Selective laser sintering has similar properties to the SLA process. SLS uses the print area that is filled with material during the workflow.
What are the purposes of 3D modeling?
3D modeling is the first stage of the production process. It allows you to replicate products by making them out of plastic or creating models for metal castings.
Stereolithography
Stereolithography often uses a resin bath. A laser is used to selectively harden the layers to create the finished product.
