Selective Laser Sintering or SLS is an industrial 3D printing technology. It builds accurate and durable parts from nylon (PA 12) materials one layer at a time. SLS is used extensively for prototypes and functional production parts.

SLS is used extensively for prototypes and functional production parts. SLS 3D printing is a mature, stable and repeatable process which can replace conventional manufacturing methods to produce parts.There are several distinct advantages to selecting SLS for your prototype or production requirements.

We have PA 12 or PA 12 + Glass fibre material options.

What is SLS (Selective Laser Sintering) 3D printing?
SLS (Selective Laser Sintering) 3D printing service is an additive manufacturing process where a laser selectively fuses powdered material layer by layer to create a solid part. It allows for the production of complex geometries and durable parts in a variety of materials, including plastics, metals, and ceramics. SLS 3D printing is used in a wide range of industries, including aerospace, automotive, and medical, for producing functional parts such as turbine blades, engine components, and surgical instruments.
