Introduction The two main 3D printing processes for creating commercial-grade nylon parts are HP Multi Jet Fusion (MJF) and Stereolithography (SLS). Each process produces parts with a high level of detail and structural integrity, but how do they compare? HP completed an experiment to examine the impact of accelerated weathering on HP Nylon PA12 W to two main SLS competitor materials. The experiment tracked changes in colour, mechanical properties, and dimensional properties. This article summarizes the main findings of the study. Test Description For this study, HP simulated long-term weathering conditions on 3D printed parts using a combination of fluorescent UV light, temperature, and condensation. The purpose was to compare Nylon PA 12 W produced with HP Multi Jet Fusion, and two comparable Nylon PA 12 materials produced with SLS 3D printing technology. Results Overall, HP Nylon PA 12 W performed better than the Nylon PA12 materials produced with SLS technology. The HP Nylon PA 12 W retained 80 – 90% of its initial mechanical properties, and it didn't show any visible aesthetic changes after extensive exposure to the test conditions. The results are summarized in the table below. Colour The colour of the HP Nylon PA12 compared to the SLS materials was compared at 200 hours, and again at 1,000 hours. After only 200 hours (approx. 8 days) of accelerated weathering, the SLS materials show a clearly visible colour change compared to the HP Nylon PA 12 W material. After 1,000 hours of accelerated testing (around 41 days), the SLS materials have an ∆Ecmc that’s at least 3 times higher than HP Nylon PA 12 W material. Mechanical Properties The graphs below show how the accelerated weathering testing affected the mechanical properties of HP Nylon PA 12 W and the SLS materials. The testing parameters can be defined as follows: Elongation at break (%) shows ductility and how much the material can stretch before breaking. Young’s modulus (MPa), also known as modulus of elasticity, measures the stiffness of the material. Tensile strength at break (MPa) measures the maximum stress a material can withstand before breaking. Charpy impact strength measures the amount of energy absorbed by a material during fracture. During the testing process, all of the materials exhibited relatively stable stiffness over time. However, the HP material exhibited stable ductility and strength properties over time, while SLS materials showed significant degradation after the testing was complete. Dimensional Changes The dimensional change of each of the materials was measured through the weathering study, using the charpy impact bars as a reference. All materials show very little change in their dimensions over time. The variations ranged mostly between +0.5% and -0.5%. Conclusion The results of the accelerated weathering study showed that the HP Nylon PA12 material showed superior colour retention and ductility when compared to the Nylon PA12 3D printed with SLS technology. The HP Nylon 12 showed great colour stability and retained 80-90% of ductility at the end of the test period. The results of the study combined with customer feedback suggests that HP Nylon PA12 W material will be suitable for applications such as medical devices or cosmetic parts where white colour consistency is important, and also suitable for parts which require an extended use or shelf life. .Data and images courtesy of HP.

Injection moulding and 3D printing are the two most commonly used methods for manufacturing plastic parts, but it can be hard to decide which is most suitable for your project. Each manufacturing process has its own advantages and can be used together as complementary manufacturing methods. This guide compares the optimal uses of each. How do 3D printing and injection moulding work? 3D printing 3D printing, or additive manufacturing, is a process of making three-dimensional solid objects from a digital file. Essentially it prints by adding material one layer at a time, from the bottom up. Additive manufacturing can produce shapes and parts that are either difficult or even impossible to create using other fabrication methods, and an increasing variety of materials are available for use with this manufacturing process. Injection moulding Injection moulding uses moulds to manufacture parts. First, a mould is made of a temperature-resistant material in a reverse image of the part being produced. Once the mould has been manufactured, plastic is injected into the mould and allowed to cool, to produce the final part. With this process, multiple parts can be manufactured at once. How do 3D printing and injection moulding compare? Production volume The volume of the production run is a major deciding factor when deciding whether to use 3D printing or injection moulding. For high-volume production of identical parts (1000+) injection molding is the most effective and affordable. For low volumes (10-100+), 3D printing is more cost-effective. For mid-volume production, other factors including design complexity, turnaround time and customization must be taken into consideration. Design complexity There are many factors which need to be considered when designing for injection moulding, as the part must be able to be removed from the mould when it is complete. A complex design must be moulded in many pieces and subsequently fit together, and delicate areas must be treated with care. Generally, more complex designs are more expensive. With 3D printing, the parts are built layer-by-layer, which gives the designer a great amount of freedom when designing the part. A complex part is as easy and affordable to 3D print as a simple design. Production time Injection moulding has a long lead time because a mould must be designed and built for the part being manufactured. It generally takes 10-20 days to design and build the mould before the parts can be produced. With 3D printing, the CAD file is simply uploaded to the printer and is ready to build, with delivery times as low as 24 hours. Customization When injection moulding, a new mould must be built each time the design is changed. This can cost anywhere from ~$100 for a 3D-printed low-volume injection mould to $100,000+ for a complex steel mould for mass production. This makes design changes very expensive and time-consuming. With 3D printing, all modifications are made with 3D modelling software. The CAD file can be sent directly to the 3D printer to be manufactured, making modifications or custom designs very quick and easy to produce. This makes 3D printing very useful for applications such as designing and testing prototypes, creating customized consumer goods, and creating medical devices formed to the human body. Material strength The injection moulding process creates parts in one single piece, making it strong across all dimensions. With 3D printing the parts are built layer by layer, making the final part weaker along the layer lines. More recently developed 3D printing processes have minimized these weaker layers, and provide strength close to injection moulded parts. Parts requiring strength in a certain direction can be oriented in the print bed to provide strength in the desired direction, as shown in this video where a 3D-printed chain link is used to lift a car. Surface finish Injection moulded parts have a wider variety of finish options than 3D-printed parts. Injection moulded parts often undergo additional surface finishing to hide imperfections such as the flow lines, knit lines, sink marks and shadow marks that are a result of injection moulding. 3D printed parts can have a textured surface finish integrated into the design, but the finished part can show slight layer lines. These lines can be minimized if the part is oriented properly in the print bed. An additional step of post-processing is often used to smooth the parts to improve aesthetics or material properties. 3D printing and injection moulding in the manufacturing cycle Often 3D printing and injection moulding are both used in the product development and manufacturing cycle. A product can be designed and tested with 3D printed prototypes, and initial production runs can be manufactured with 3D printing until the production volume is high enough to justify the expense of injection moulding. In this case, the part can be designed for the injection moulding process so the transition between the two manufacturing processes is seamless. 3D printing is again used in the end-stage lifecycle of a product to create legacy parts for older or discontinued equipment. 3D printing can also be used to create moulds for injection moulding, or create unique parts such as jigs and fixtures. Summary Conclusion Both injection moulding and 3D printing serve different and complementary purposes in manufacturing. When choosing which one to use, it is important to consider which factors are most important, including cost, production volume, delivery time, material properties and your stage in the design and manufacturing process.

Cerakote Ceramic coating is a world-leading thin-film coating that is applied to plastic, metal and other materials to enhance their physical performance and appearance including scratch resistance, wear resistance, waterproofing, chemical resistance, and UV protection. Industrial Applications of Cerakote The performance-enhancing properties of Cerakote make it a logical choice for a wide variety of industries and manufacturing processes. For example, Cerakote is used for corrosion protection in the oil and gas industry, heat resistance in the aerospace sector, performance coatings in the automotive industry, extending the life of sporting and hunting equipment, and increasing the useful life of jigs and fixtures. Recommended applications include tools, consumer goods, eyeglasses, sporting equipment, robotics, electronics, fresh and saltwater applications and other applications where a durable performance coating is required. A wide variety of manufacturers and suppliers rely on Cerakote coatings including Boeing, SpaceX, Blue Origin, Lockheed-Martin, US Department of Defence, Zipline, Ford, and Lamborghini. Benefits of Cerakote Destructive testing has shown the superiority of Cerakote to other standard finishes. For example, a Taber abrasion wear test was performed by NIC Industries to compare the durability of Cerakote to 6 other popular coatings. In this test, Cerakote lasted nearly twice as long as the nearest competitive finish and 24 times as long as the furthest competitive finish. Another study tested the impact resistance of Cerakote. In this test, a 1 oz slug was fired from a 12-gauge shotgun at a piece of metal plate treated with Cerakote. The area behind and surrounding the impact site showed no cracking or loss of adhesion, even in the areas of greatest deformity. Cerakote in Additive Manufacturing of Plastic Parts Cerakote is an increasingly popular finish used in additive manufacturing because it’s ability to enhance the performance and aesthetics of 3D printed plastic parts. This diversifies the potential end-use applications of the parts; for example, Cerakoted plastics are emerging as faster, less expensive alternatives to metal parts, especially for small-to-medium volume manufacturing. An example is provided in this case study, where HP and Aerosport re-designed 2 different metal assemblies to be 3D printed with Nylon 12. Each was able to reduce assembly time, weight, cost of manufacturing and overall production times by a significant amount. To validate the performance of Cerakote when applied to 3D-printed plastic parts, the Cerakote Technical Training Team completed ASTM testing on Nylon PA12 plastic coated with 2 different types of Cerakote finishes. The tests showed excellent results, including no chipping or cracking in cross-hatch adhesion tests, and minimal effect after 24 hour immersion in water, acetone or diesel.
