With every 3D printing technology there are strategies to get the best result with your print. When designing parts for HP Multi Jet Fusion, it is possible to achieve very fine dimensional accuracy, with Cpk values comparable to injection molding. HP has provided a set of guidelines to help maximize the accuracy of your design. Minimum Specifications The recommended minimum dimensions for printed features are between 0.1 mm and 0.5 mm Minimum hole diameter 0.5 mm Minimum shaft diameter 0.5 mm Minimum printable font size 6 pt Minimum printable features or details (width) 0.1 mm Minimum clearance 0.5 mm Minimum slit between walls/embossed details 0.5 mm Embossed and Engraved Details Text, numbers or drawings should be at least 1 mm deep. Additional Considerations When designing for detail, there are several other considerations to keep in mind. When possible, place small features with critical dimensions—such as pins, holes, and raised texts—in the same plane. Design parts with a smooth cross-section transition. When possible, lighten parts and minimize the chance of warpage by hollowing them or adding internal lattices. Avoid long, thin, flat parts with a ratio of length to width greater than 10:1. Avoid predominantly long and thin curved segments in your part design. Avoid ridges and ribs on large, flat areas.

Each 3D printing technology has a unique set of design recommendations to ensure the best result. We would like to share the design specifications provided by HP for their HP Multi Jet Fusion 3D printing technology to help you achieve the best results possible. These design guidelines apply to all Multi Jet Fusion materials, including Nylon PA12, Nylon PA12 Glass Bead, Polypropylene, and TPU Flexible Polymer. What is HP Multi Jet Fusion (MJF)? Before starting, it helps to understand what HP Multi Jet Fusion (MJF) is and how it differs from other 3D printing technologies. According to HP, The MJF printing process is a combination of Powder Bed Fusion and binder jetting technologies. Unlike SLS or FDM, which use a point-by-point printing approach, HP MJF technology can print a complete layer at the same time. A layer of powder material is spread on the print bed, then fusing and detailing agents are deposited at voxel-level on top of the powder. These define the regions of the layer that need to be fused or protected from fusion respectively. The bed is heated and the areas where the fusing agent was deposited are fused together.. Once these fused layers cool down, they solidify to form the designed 3D-printed part. Wall thickness When you’re creating a 3D design for Multi Jet Fusion, the minimum recommended wall thickness is 0.3mm for short walls oriented in the XY plane, and 0.5mm for short walls oriented on the Z plane. If you design your part to be optimized for a specific orientation, make sure you make this clear to the person or company printing your part. Cantilevers When printing a cantilever, the minimum wall thickness depends on the aspect ratio, which is the length divided by the width. For a cantilever with a width of less than 1mm, the aspect ratio should be less than 1. There are no specific recommendations for widths of 1mm or larger, but for parts with a high aspect ratio, it is recommended to increase the wall thickness or to add ribs or fillets to reinforce the part. Connecting Parts Sometimes a pair of printed parts need to fit together to form the final application. To ensure correct assembly, a good starting point would be to leave a gap between the interface areas of these parts of 0.4 mm (+/- 0.2 mm for each part). Moving Parts As a general rule, spacing and clearance between faces of parts printed as assemblies should be a minimum of 0.7mm. Parts with walls which are 30mm or thicker should have a larger gap between each side to ensure proper performance. Parts with walls that are thinner than 3mm thatcan have a clearance as low as 0.3mm, but this depends on the design. Testing may be necessary to ensure quality performance. Thin or Long Parts Thin and long parts are susceptible to non-uniform cooling, which may cause uneven shrinkage along the printed part. This can warp the part from it's original shape. The potential for warpage can be minimized with good design practices. A general guideline is that any part with an aspect ratio higher than 10:1, an abrupt change in its cross-section, or a predominantly long and thin curved segment is susceptible to warpage. These include thin and long parts; parts with abrupt changes in cross-sections; and thin and curved surfaces. To minimize the possibility of deformation, there are several guidelines to follow when designing the part. These include: Increase the thickness of long walls to reduce their aspect ratios. Avoid ridges and ribs on large, flat areas. Re-design parts with high potential stress and smoothen their cross-section transitions. Lighten the parts by hollowing them or by adding internal lattices. Hollow Parts For large or thick parts, it is recommended to minimize the risk of warping by hollowing the part or adding an internal lattice structure. The minimum recommended wall thickness is 2mm, but better mechanical properties are achieved with thicker walls. The optimum choice is dependent upon the application. Hollowing can be easily achieved with professional software such as SolidWorks, Materialise Magics, Autodesk and Netfabb. Depending on the end-use application, the part can be left solid, or drain holes can be added to remove the powder in the post-processing process. Ensure the drain holes are at least 4 mm wide if there is a single drain hole, or 2+ mm wide for multiple escape holes. When placing the holes ensure they are placed in a way that forced air can be used to effectively clean out trapped powder. If no escape holes are provided and powder remains within the part, the part will be heavier and stronger than with the fully hollow option. Leaving the powder trapped within a part also saves post-processing time since powder extraction is not required. Lattice structures Lattice structures are used in thick or large parts to minimize the chance of warping or for producing lighter parts. Replacing solid materials with a lattice also reduces the cost to 3D print the part. This design optimization strategy involves hollowing a part and replacing the internal solid mass with a lattice structure that provides mechanical integrity. This re-design can be automated with professional software such as Materialise Magics or nTopology. Additional Considerations Material Choice Each type of material that is 3D printed with HP Multi Jet Fusion has different properties. Select your material based on the properties you desire such as strength, flexibility, biocompatibility, weather resistance, or chemical resistance. File Resolution The resolution of your file is an important factor to consider when 3D printing your part. If your file is too low resolution it may lack quality, and if the resolution is too high then the file size may be too large for the printer to read. Keep your file size under 100MB if you can.

With the HP Jet Fusion 5200 Series 3D Printing Solution, Dundon Motorsports has been able to accelerate production, experiment with new designs, grow their product portfolio, and expand to new markets. Dundon Motorsports provides high-performance parts to the motorsports world. One of Dundon's projects was to upgrade the performance and horsepower of Porsche GT racecars. According to Dundon Motorsports’ Jamie Bopp, “The nature of the car has been about freedom, about emotional release, about joy, so Dundon is in the business of taking joyful cars and making them more joyful.” Challenge The challenge in this project was to ensure the upgraded parts fit under the hood and within the confines of air conditioner, the power steering pump, and other parts. The other challenge was to ensure the design and manufacturing of the parts was time- and cost-effective. “Finding an innovative way to make all of these parts fit is one thing,” said Bopp. “The second thing is the business side of the situation. If we were able to injection mold or CNC machine these parts, the costs would be stratospheric.” Dundon looked into various manufacturing methods to produce an intake manifold, including injection molding and CNC machining. Injection molding would cost nearly $65,000 to produce a mold, which was prohibitively expensive, especially for low-volume manufacturing. CNC machining was not ideal because the tooling is difficult to control in the long, hollow parts due to the long reach of the tool and the vibration on the tool bit. also, aluminum was not ideal to manufacture the part because it transfers heat too easily to the intake air. as an alternative, they looked into 3D printing as a manufacturing option. Solution Dundon chose to work with 3D printing as a manufacturing option because the same technology could be used for both prototyping and final production of the parts. After researching the various options, they chose HP Multi Jet Fusion 3D printing technology for its capacity and repeatability. Their material of choice for building the parts is HP Nylon 12, for it's all-purpose robustness and ability to provide an air-tight seal. According to Bopp, “With [HP] MJF, we’re able to not just make a single-printed usable part, but we’re also able to make assemblies that we bolt together to adapt to what we would want to make in the end”. Result Dundon now produces many different parts with HP Multi Jet Fusion technology including intake plenums, intake runners, and air filter boxes. With this manufacturing method they are also able to easily alter the designs to improve functionality. Bopp sees HP 3D Printing as a disruptive technology in the industry. “We can draw a part and, within a few days to a week, have that part in our hands and be testing it on a car, when previously it’s taken development cycles that were quarters, months, at best cases, weeks. If we need to make a change, we can now make that change in days... [HP Multi Jet Fusion] has become an enabler for us. It has enabled us to operate and ‘punch above our weight class’ quite effectively.” Additive Manufacturing with Tempus 3D As one of only a select few HP Certified Production Professionals in Canada, Tempus 3D can help you achieve the advantages of additive manufacturing with Multi Jet Fusion.

Multi Jet Fusion is a 3D printing process that is designed to build functional prototypes and manufacture low-to-mid volume production runs of end-use parts. This technology has become one of the leading additive manufacturing technologies for industrial applications because it can quickly and consistently manufacture parts with high tensile strength, fine detail, and overall excellent material properties. This article explains how Multi Jet Fusion works and it's unique advantages. How does HP Multi Jet Fusion technology work? HP Multi Jet Fusion (MJF) uses a powder-bed fusion 3D printing process, in which small powder particles (with a size of 30 nm) are fused together with heat. To build the parts, a fine layer of powder is deposited in the build chamber. A fusing agent is applied in select areas, creating a 2-dimensional profile of the part. Next, the fusion agent is heated with infrared light, which fuses the particles together and to the layers below. An additional agent is used to define the edges of the part and ensure dimensional accuracy. When a layer is finished, another layer of powder is deposited and the process is repeated. When the part is finished, the excess powder is removed and the parts are cleaned with a bead blaster. At this point the parts are ready for use or may receive further treatment to enhance their looks or material properties. Parts may also be machined for higher precision on features like mating surfaces, holes or internal threads. Advantages of Multi Jet Fusion Multi Jet Fusion is ideal for building prototypes that can be used in their end-use application and for small-to-medium volume production of final parts. The materials used in Multi Jet Fusion have characteristics that make them valuable for a wide variety of applications, including biocompatibility, chemical resistance, and resistance to water and UV degradation. They are used in a wide variety of industries including automotive, aerospace, medical devices, education, electrical, and robotics. How does HP Multi Jet Fusion compare to other 3D printing technologies? HP MJF is most commonly compared to Select Laser Sintering, also known as SLS. Both 3D printing technologies use heat to fuse layers of fine powder layer-by-layer in a build chamber, but they differ in the way heat is applied. With SLS, a laser heats the shape of the part being manufactured, point-by-point. With MJF, infrared lights heat the whole surface in one pass. The method of manufacturing directly affects the mechanical properties of the parts being printed and the speed of manufacturing. With SLS, the printing speed depends on how many parts are being built. A laser has to draw the surface of each model separately. This is an advantage when just only one part is printed, but with larger print volumes SLS takes longer than MJF. This also results in a higher cost for larger print volumes. With Multi Jet Fusion, the printing speed is the same no matter how many parts are being printed because the time needed to make each layer is the same. This provides a cost and speed advantage when many parts are printed at once and the whole build volume is filled. Usually, low-volume production is more cost-effective on HP printers. Multi Jet Fusion Materials One major advantage of Multi Jet Fusion is the ability to print a variety of materials, each with unique advantages. Nylon Polyamide 12 (Nylon 12) Nylon 12 is an excellent all-purpose material with properties that make it useful for a variety of applications. These include chemical resistance, water and UV resistance, and biocompatibility. Nylon 12 is the most commonly used material produced with HP Multi Jet Fusion. Nylon 12 with glass beads (Nylon GB) Nylon GB material is filled with 40% glass microspheres. It has all of the great material properties of Nylon 12, but the glass beads increase stiffness adn improve dimensional accuracy and reduce the possibility of warping with flat parts. Nylon GB is commonly used for thin, rigid parts such as casings and housings, fixtures and tools. Thermoplastic Polyurethane (TPU) TPU creates durable, strong,flexible parts. It is commonly used for applications where shock absorption capacity, flexibility or energy return is required.It has many applications including car interior components, industrial tools, pipes, grippers, footwear, orthopedics and sports protection equipment. Nylon Polyamide 11 (Nylon 11) Nylon 11 is a strong and flexible, producing high-density parts with fine detail and high accuracy. It is biocompatible and resistant to oils and greases. It is also stable to UV light and weather, and has good elasticity and impact resistance. Polypropylene (PP) Polypropylene is chemical resistant and weldable, with low moisture absorption and great mechanical properties. Polypropylene is an excellent choice for anything that needs to be light, water-tight, and durable. It is one of the most common polymers you find around the house, often used for plastic containers. What is the Digital Manufacturing Network? HP has established a digital manufacturing network with service providers certified as HP Multi Jet Fusion Production Professionals.

How Biesse has increased design freedom, improved speed-to-market, and met customer requirements more quickly and more profitably with industrial 3D printing technology. The Biesse Group was founded in Pesaro, Italy in 1969 by Giancarlo Selci. The company offers modular solutions from the design of turnkey systems for large furniture manufacturers to individual automatic machines and workstations for small and medium-sized businesses. The company has a variety of subsidiaries which design, manufacture and market a full range of technologies and solutions for the wood industry, including furniture, windows and other wood components. Biesse has also recently expanded to plastic processing machines, with solutions designed specifically for this growing market. Challenge “Within Biesse, we have a business unit entirely dedicated to the supply of machines that allow edging“, says the company's technical and prototype office manager, Marco Mencarini.“They allow the application of plastic or wood to the edges of the furniture. As you can imagine, our machines have to support a diverse set of assembly needs. To support them, we need to create a wide range of highly customized parts and tools.” Some Biesse edgebanding machines operate at very high speed and consist of many moving parts that help the customer guide the edge through the assembly using supports, channels and guides. In many cases, these production aids have to be tailored to the beading material used.The challenge they faced was the ability to quickly and affordably design and build these customized pieces. Solution Biesse uses a variety of manufacturing processes in it's product development, including 3D printing. “We’ve worked with 3D printing since late 1990’s, primarily for rapid prototyping,” says Mr. Mencarini. “The HP Jet Fusion 3D Printing Solution allows us to do much more, including helping us bridge the lead-time gap of making metal molds and even allowing us to produce final parts, especially in short-runs that would be impossible to profitably manufacture otherwise.” As 3D printing has matured, they have continually explored new opportunities. When HP launched its first HP Multi Jet Fusion 3D printers, Biesse became one of the first to adopt an HP Jet Fusion 3D 4200 printer. The company chose HP because HP's Multi Jet Fusion technology meets a variety of needs. In addition to simple models, Biesse wanted a more efficient way to create functional prototypes of its various mechanical components, including connecting rods, pulleys, sprockets, couplings and other parts. An example is the gear box pictured below. The part initially required multiple manufacturing technologies, including injection molding and computer numerical control (CNC) machining. Biesse's engineers wanted to assess whether the part could be redesigned using 3D printing. The design and manufacturing team optimized the geometry of the part in ways that couldn't be made with traditional manufacturing processes, such as CNC machining and injection molding), creating a part that was more efficient and less expensive part to produce usign HP Multi Jet Fusion 3D printing technology. Result With creative part redesign and HP Multi Jet Fuison 3D printing processes, The Biesse team was able to reduce the lead times required to create and improve their products. They found significant productivity gains over other other 3D printing technologies and over traditional manufacturing techniques. This technology allows Biesse to beta-test a series of parts in hours rather than weeks. The quality of the parts features excellent surface quality, allowing Biesse to sandblast and paint parts comparable to other parts that are injection molded or computer numerically controlled (CNC) machined. Biesse compared the cost and time savings to manufacture a series of 100 of these mechanical parts with HP Multi Jet Fusion (MJF), CNC machining, and injection molding. Their results showed significant advantages of MJF over traditional manufacturing processes, as summarized below. HP Multi Jet Fusion CNC Injection Molding cost: 100% cost: 300% cost first year: 700% lead time: 1 day lead time: 20 days cost from year 2: 20% lead time: 90 days This case study, originally published by HP and Biesse, shows the potential for additive manufactuing with HP Multi Jet Fusion technology to revolutionize the manufacturing industry, saving companies significant time and money.

Ledcor teams up with Tempus 3D printing to alleviate supply chain issues, improve part design and minimize manufacturing time. Ledcor is North American construction company which was having trouble finding replacements for ball valves used in applying calcium chloride to road surfaces for dust control and other purposes. After making exhaustive attempts to source new valves through their traditional suppliers they were faced with a six month or greater lead-time for delivery. Ledcor approached Tempus for a solution, with the explicit need to get a functioning ball valve in their hands within four weeks. They also wanted to take the opportunity to improve the design of the valve to address historical weak points and improve functionality. The main weak point had been the seam in the parts from where the two injection molded parts had fit together. This seam was prone to holding water and then freezing during the cold Canadian winters, which resulted in the parts cracking and no longer holding a seal. The team at Tempus 3D collaborated with their partners at the Selkirk Technology Access Centre (STAC) part of Selkirk Innovates team (www.selkirk.ca/innovates) to re-design the part and manufacture the final product within the specified timeline and deliverables. The original valve was scanned with a Creaform HandySCAN 3D scanner to determine the critical dimensions, and the part was redesigned to improve it’s function and address critical failure points. A prototype of the valve casing was 3D printed and tested for fit and function. After additional design changes, the final product was manufactured using an HP Multi Jet Fusion 5200 3D printer for it’s dimensional accuracy and quality. Nylon PA 12 was selected as the material for its overall durability and resistance to water, chemicals and UV rays. Once printing was complete was sealed with AMT Post Pro vapour smoothing technology to improve water and chemical resistance. Finally, due to the tight dimensional requirements and fit, the low-tolerance surfaces of the valve were machined to ensure exact compliance with the client specifications. This whole process was completed in less than four weeks, and future parts could be manufactured and delivered in less than two weeks. The cost savings to Ledcor were significant, both in terms of saved downtime and overall cost of manufacturing in comparison to the alternative options of injection molding or CNC machining. Ledcor and Tempus continue to look for ways to integrate 3D printing into their operations to reduce their supply chain risk and improve part functionality and quality. With Tempus’ location in the interior of British Columbia, it is uniquely capable of serving markets across Western Canada with cost-effective overnight shipping and the ability to turn around rush orders in as little as 36 hours. We at Tempus feel this is just the beginning of what manufacturing will look like in the future; it will be more responsive, more custom, and more local allowing innovators across sectors to bring products to market quicker and in a more environmentally friendly way.

The design freedom and quality materials provided by HP Jet Fusion 3D Printing Solutions allow Prensilia and Elastico Disegno to create a robotic hand called ‘Mia’ In 2012, Prensilia set itself the goal of developing a robotic hand casing that was light, highly functional, aesthetically pleasing and structurally solid to protect the internal mechanical and electronic components of the device. For this project, Prensilia collaborated with Elastico Disegno to help them overcome the limits set by traditional production methods and other filament-based 3D printing technologies, such as the inability to perfectly adapt the external covers to the shape of internal mechanics, while maintaining exceptional surface quality. Elastico Disegno chose to use PTC Creo because it is able to design mechanical and anatomical parts in a single environment, thus accelerating development and minimizing the number of components required, flexibly size the product to adapt to any variation of the components, communicate directly with the technical development departments, and simply exchange data with the customer to speed up design operations. The result of this innovative project is Mia, a robotic hand equipped with sensors and connected to a trans-radial titanium implant (between the elbow and the wrist). The cables and electrodes that connect the muscles and nerves pass through the two bones of the forearm (the ulna and the radius) before reaching the robotic hand, returning the information captured by the fingers and improving movement. Due to the complexity of most of Mia's components, Prensilia and Elastico Disegno saw additive manufacturing as the only valid technology for this project. The external coatings of the hand and fingers are made with HP Multi Jet Fusion technology using HP nylon PA 12 material, which combines strength and structural support, as well as a surface finish able to guarantee the desired aesthetics from Prensilia. These components include wearing parts, such as buttons and snap fasteners, which have passed all functionality tests. The soft parts of Mia's fingertips are made from silicone molds, also made by HP Multi Jet Fusion and Nylon 12. According to Prensilia, replacing metal molds with plastic molds has reduced the investment required and production times, without compromising performance and external finish. Marco Controzzi, Founder of Prensilia, described their reaction to the final product. “The first time we tried Mia on a patient, the reaction was, ‘How light!’,” she said. “We reached the desired level of robustness thanks to the improvement of the internal mechanics and by 3D printing the external casing with HP Multi Jet Fusion, which allows for the combination of rigidity and surface finish.” Controzzi also sees the ability to rapidly iterate as a major advantage of HP Multi Jet Fusion technology. “Another important advantage offered by 3D printing to technological frontier products such as ours is the possibility of offering customers updated products,” Controzzi said. In 2019, Mia received the Red Dot Award, one of the world's largest and most important design awards for product design.

Montreal-based medical services innovator uses 3D printing technology to develop custom form-fitted and breathable back braces to improve patient comfort and outcomes. A medical services innovator based in Montreal, Quebec approached Tempus 3D with a back brace design that they wanted to have manufactured. After comparing 3D printing service providers, they approached Tempus 3D for a solution. Challenge The biggest challenge with this project was the large size of the brace. Not many industrial 3D printers are capable of manufacturing such a large piece, and when a part has large, flat areas there is a risk of the piece warping during the manufacturing process. A second consideration was to choose a medical-grade material with the strength, durability and flexibility to provide comfortable support. Solution The team at Tempus 3D was able to leverage HP Multi Jet Fusion 3D printing technology, which provides the class-leading build volume and part quality required to successfully manufacture this design. With this printer all of the parts for the brace could all be fit into one print run, which saved manufacturing time and cost. ​ The greatest risk in the production of the brace was the potential for the pieces to warp, because the difference in temperatures across large, flat pieces can bend them as they cool. The team at Tempus 3D collaborated with experts at HP and Hawkridge Systems to ensure the part orientation and print settings were optimized for the best result. The other consideration in building the brace was to select a material that was suitable for a medical device used on or near the skin. Nylon 12 was the material of choice because it has high tensile strength, is waterproof, and is certified biocompatible. It also has enough flexibility to accommodate the patient's movement without losing its support. Result In collaboration with their manufacturing network, the team at Tempus 3D was able to produce a brace that exceeded the client's expectations in terms of finish, color, accuracy, and cost. We at Tempus are excited to help local businesses meet their manufacturing goals as a part of the industry 4.0 network which allows innovators across sectors to bring products to market quicker and in a more environmentally friendly way.

Additive manufacturing, also known as industrial 3D printing, has added a new dimension the manufacturing industry. One of the many advantages of additive manufacturing is the ability to build forms that are not achievable with traditional manufacturing methods. This gives engineers the freedom to focus more on optimizing the component design, and less on the limitations of the manufacturing process. The many benefits include improved part functionality, weight reduction, decreased assembly time, and lower overall manufacturing costs, as shown in the two case studies below. HP - Optimized Drill Extraction Shoe HP's engineers re-designed a drill extraction shoe that was used in the manufacturing process to create print heads. The original assembly was manufactured from machined aluminum and standard parts. The final design integrated the various parts into one single piece, and was designed to be manufactured of Nylon 12 with the HP Multi Jet Fusion 3D printer. RESULTS Multi-part assembly reduced to a single piece The resulting part was watertight, without additional post-processing Manufacturing costs reduced by 95% Weight reduced by 90% Lead time reduced from 3-5 days to 24 hours Aerosport - Redesigning a rudder trim system Aerosport Modeling and Design Inc. was redesigning a rudder trim system used in an instrument panel which was used as part of their manufacturing assembly line. The original assembly was built of 16 machined and standard metal parts. With the freedom of design inherent in additive manfuacturing, the engineers were able to reduce a 16 part metal assembly to four pieces 3D printed on HP Multi Jet Fusion 3D printing technology with low-cost Nylon PA12. RESULTS Reduce the final design from a 16 part assembly to only 4 parts Decrease the manufacturing lead time to 24 hours Minimize the assembly time with only 1/6 the number of parts Significant reduction in cost with reduced material costs, shorter assembly time and eliminated need to maintain a part inventory Additive Manufacturing with Tempus 3D Whether you are learning how to design for additive manufacturing or looking for a reliable Canadian manufacturer to produce high-quality, affordable plastic parts, the team at Tempus 3D is available to help.

Airforce Velocity Stacks is an Alberta-based business that produces custom snowbike intakes for customers across North America. Airforce was re-designing a throttle body to boost engine performance and was looking for a local manufacturer that could support them to design and produce prototypes that were precise and robust enough to test in real-life conditions, but affordable enough to make multiple design iterations to compare different options. Airforce approached Tempus 3D for a solution. Tempus 3D collaborated with their design and manufacturing network to help with the re-design and manufacturing of the throttle body prototype for Airforce. To start, the original part had to be digitized and converted to an editable CAD file. This task was completed by the team at the Selkirk Technology Access Center (STAC) using their commercial laser scanner and CAD design software. The CAD file was used to create prototypes of the desired design upgrades with the support of Tempus 3D’s design partner, Bruce Fitz-Earle. The final prototype was 3D printed by Tempus 3D on their HP Multi Jet Fusion 5200 using Nylon PA12. Nylon PA12 is ideal for creating functional prototypes because it is affordable yet tough, resilient, and is resistant to moisture and chemicals. HP MJF 3D printers are designed for commercial use, producing plastic parts with the precision, density and uniformity required to create an accurate design and stand up to testing in a real-world environment. The accuracy and quality provided with HP MJF 3D printer allowed for the parts to be fit onto bikes for not just dyno testing in the shop, but for performance testing on the track and in the mountains. The team at Airforce were able to put the prototypes through a range of testing in a condensed time period that would have been impossible using other manufacturing techniques and materials. ​ Airforce was able to get their product to market quickly and affordably with the support of the design and manufacturing network available through Tempus 3D. Airforce, Tempus, and Tempus' development partners continue to work together developing new and innovative products using some of the most sophisticated advanced manufacturing tools. As Airforce continues to invest in innovation Tempus 3D will be there to help them with prototyping and design, and get their products from concept to market in record time. With Tempus’ location in the interior of British Columbia it is uniquely capable of serving the Canadian market with local manufacturing and design services.
