Nylon

Multi Jet Fusion (MJF) nylon is a synthetic 3D printing polymer material that is strong, durable and flexible. MJF nylon is generally considered more frequently used for end-use parts and functional testing under higher loads. With its modular design and faster production speeds, MJF nylon is a cost-effective option for higher bridging production volumes.. Nylons offered: Nylon 11, Nylon 12, and Nylon 12 Glass-Filled

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

Cost Saving Tip

When choosing to 3D print higher part quantities (20+), SLS stands out as the most economical additive manufacturing process.

About the Process

Selective Laser Sintering (SLS) harnesses high-powered lasers to selectively fuse powdered material, binding it together layer by layer to form a solid structure. It is frequently mistaken for a similar process known as Selective Laser Melting (SLM), differing in that it solely sinters the powders together rather than achieving full melting.

During the process, parts are supported by unsintered powder in each layer, which remains distributed across the build volume until each layer is fused. Upon completion, the part is extracted from the residual powder and manually cleaned, often utilizing water or air jets.

Although parts produced through this method can incorporate some metal, they typically consist of plastic composites that offer a favorable strength-to-weight ratio and are obtainable at a relatively low cost. While parts requiring structural integrity akin to forged solid metal necessitate Direct Metal Laser Sintering (DMLS), the exceptional precision, cost-effective feedstock, and capability to reach high temperatures with SLS printing render it a highly beneficial technology applicable across a wide spectrum of industries, from architectural modeling to aircraft control surfaces and surgical instruments.

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 […]
