Selective laser sintering


SLS is a process that can produce strong and accurate functional parts by sintering the powder into solid parts layer by layer usually with high powered laser beams. Nylon is the most common material used for the SLS process. The finished parts usually have a rough outer texture. Flexible parts can also be made out of SLS. Nylon parts are known for their strength. Because of the homogeneity of the process, the parts are reliable and can be used as functional parts. The process is relatively inexpensive compared to SLA.


SLS parts made out of nylon PA-12 2200 are often utilized for end uses as functional parts. This is due to their excellent long term constant behavior, high strength, and stiffness. They are bio-compatible to a certain extent. They are food safe too.

Nylon PA 12 2200 cc ₹ 80



Dyeing can be used for SLS nylon parts to impart colours to the finished parts. The natural colour of the parts is white.

Sand Blasting

Sand Blasting is used on SLS and MJF parts to give them a smooth finish after printing is done. The output parts of these processes generally have a rough surface finish. Sand Blacsting can help smooth their surfaces to a good extent.
