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.

340 x 340 x 600 mm (P390) or 700 x 380 x 580 mm (P760)

Gaps for Mating Parts

0.5 mm clearance between features

Tolerance

+/- (0.25 mm + 0.002mm/mm)

  • For long, thin parts: use ribbing to mitigate warping risks.

Cost Saving Tip

If using 3D printing for higher part quantity fabrication (20+), SLS will be the most cost effective additive manufacturing process.

About the Process

Selective Laser Sintering uses high-powered lasers to sinter powdered material, binding it together to create a solid structure. It is often confused with another similar process called Selective Laser Melting (SLM), the difference being that it only sinters the powders together as opposed to achieving a full melt.

Parts are supported by unsintered powder in each layer, which remain spread across the build volume until each layer is fused together. Once complete, the part is removed from the remaining powder and cleaned by hand and using water/air jets.

While parts created using this technology can contain some metal, they are usually plastic composites that present a good strength to weight ratio and can be acquired relatively cheaply. For parts that must be structurally as sound as forged solid metal, DMLS is required. Still, the high level of accuracy, relatively cheap feedstock, and high temperatures achievable with SLS printing make it an incredibly useful technology with a broad range of applications ranging from architectural models to control surfaces of aircraft and surgical tools.
