Selective Laser Sintering (SLS)


Selective Laser Sintering

Efficient Powder-based Technology

Selective Laser Sintering (SLS) is a powder-based technology that uses a C02 laser to sinter each layer together. With a wide variety of plastic powders available, you can easily find a material that will create the end-use part you envisioned.

Because of the abundance in material options, end-use parts that are used in demanding and harsh environments can be produced with reduced tooling costs and faster lead times.


Selective Laser Sintering (SLS) Process

Step 1​

Layer of powdered material is applied to build platform.

Step 2​

Laser is used to solidify a cross-section of powdered material.

Step 3​

Platform is lowered and next layer of powder is applied. Process is repeated.

Step 4​

Unused powder is removed. Finish part is revealed.
