Volume production of end-use parts

There are many types of 3D printing available, but to be able to economically and reliably produce one to tens of thousands of parts in engineering grade material, Multi Jet Fusion technology is the logical choice. The speed of production, level of detail, affordability, and overall quality of the end product is unparalleled in the industry.

Tempus 3D prints in-house with the HP Multi Jet Fusion 5200 because it's unbeatable combination of speed, cost and quality makes it the perfect fit for on-demand manufacturing of functional prototypes and end-use plastic parts, on-time and on-budget.

How does Multi Jet Fusion work?

Multi Jet Fusion (MJF) is a Powder Bed Fusion technology designed by HP for manufacturing end-use plastic parts. This unique printing process produces parts with high density and low porosity, with excellent mechanical properties and an exceptionally smooth surface straight out of the printer, requiring minimal post-production finishing. This means short lead times, ideal for functional prototypes and small- to medium-production runs of engineering grade end-use parts. Additional post-production treatment can enhance the surface finish and performance of the parts.

Ideal applications for Multi Jet Fusion

Functional prototyping

MJF is ideal for building prototypes that can be tested in real-world applications for form, fit and function. 

Low- to mid-volume production

Multi Jet Fusion is up to 10x faster than it's competitors, making it an affordable alternative to injection molding.

Mass customization

MJF is a popular choice for industries where customization is important, such as medical and consumer goods.

Multi Jet Fusion materials

HP Nylon PA12

HP Nylon PA12 is by far the most popular material choice for Multi Jet Fusion because of it's excellent mechanical properties, fine detail, and affordability. Nylon PA12 is water tight, air tight, is resistant to chemicals and is certified biocompatible. It is ideal for functional prototypes and end-use applications, used in a wide variety of industries including automotive, aerospace, medical and consumer goods.

How does Multi Jet Fusion compare to other 3D printing technologies?

There are many types of 3D printing available, but to be able to economically and reliably produce one to tens of thousands of parts in engineering grade material, powder bed technologies are the logical choice. The speed of production, level of detail, affordability, and overall quality of the end product sets this technology apart from all other 3D printing processes.

Multi Jet Fusion (MJF) is most closely comparable to Selective Laser Sintering (SLS) technology. Like SLS it works by adding sequential layers of polymer powder into a build chamber, and the most common material for both is Nylon PA12. In contrast to SLS which uses a single point laser, MJF uses a combination of a fusing agent jetted onto the powder surface and a high powered heat source to selectively fuse areas of each layer together to form parts. This means that Multi Jet Fusion produces parts with similar material properties, but at a much higher volume per print.

MJF and SLS have similar material properties, but Multi Jet Fusion has several distinct advantages:

  • MJF is significantly faster than SLS.

  • MJF is 15-30% less expensive than SLS, with greater cost advantage at higher volumes.

  • MJF parts have superior strength and flexibility and have more homogenous mechanical properties compared to SLS, which is weaker along the print axis.
