Nylon

Multi Jet Fusion (MJF) Nylon is a synthetic 3D printed polymer material that’s strong, durable, and flexible. MJF Nylon is typically considered more often for end-use parts and functional testing under higher loads. MJF Nylon is a cost-effective option for higher bridge production quantities because of the machine’s modular design and faster production speed.

Design Recommendations

Maximum Part Size

380 x 284 x 380 mm 15 x 11.2 x 15 in

Gaps for Mating Parts

0.2 mm minimum; we recommend 0.3 mm to ensure good fit

Tolerance

± (0.3mm + 0.002mm/mm)

Min Wall Thickness

1 mm for consistent measurement or mechanical properties

Cost Saving Tip

When it comes to MJF parts, it's more cost-effective to print in large quantities to use all available build space.

Finishing Options

Name

Vapor Smoothing

Applicable Materials

PA 12 Glass Beads

Colors

While steam smoothing itself doesn't apply color to the part, it makes the color of the part more vibrant - so a black-stained part becomes a deeper, more glossy black. Please note that the gray (original) MJF part will turn to a near black if steam smoothed because the gray surface melts into the black inner part during the process

Applications

Enhance appearance and improve mechanical properties

Texture

Smooth and glossy

About the Process

Multi Jet Fusion (MJF), also known as MJF, stands as a state-of-the-art 3D printing innovation from HP, enabling companies to expedite time-to-market with production-grade 3D printing capabilities.

This technology operates by dispersing a fine layer of powder, applying fluid to designated areas, and subsequently fusing those regions. The raw powder serves as support for parts within the build bed. Upon completion, parts undergo cooling, cleaning, and media blasting to achieve a smoother surface finish.

MJF proves highly advantageous for bridge production volumes, especially considering its comparatively higher daily output compared to alternative 3D printing methods. Additionally, it excels in functional testing and form/fit validation, owing to its superior resolution, tensile strength, and heat deflection properties. Moreover, MJF facilitates the production of end-use parts and serves as an excellent transition into injection molding, courtesy of its consistent mechanical properties.

This versatile process finds application across a myriad of industries, including healthcare, automotive, and consumer electronics. Common applications span prosthetics, aerospace camera enclosures, dental molds, and automotive component molds.

3D Printing vs Injection Molding

3D printing and injection molding are each used to produce plastic parts. However, these processes are not mutually exclusive because some projects that begin with 3D printing end with injection molding.  3D printing is typically used for early-stage prototypes, evolving designs, and part geometries that can’t be produced with other methods. Because this form of […]
