SLA printing uses liquid resin which is toxic and messy. It can also be time-consuming to clean off a completed object during post-processing. SLS printing, on the other hand, uses powder which is much easier to deal with.
Does SLS use liquid resin?
So, what is the difference between SLA and SLS? There are some common denominators, for example, both use a laser to trace out and build individual layers. For SLA a liquid resin is cured, whereas in SLS powder is selectively fused together. Comparing the techniques isn’t easy as they both have pros and cons.

The WEIRD resin printing trick that PERFECTLY tensions …
When should I replace FEP film?
FEP films should be replaced when they have major signs of wear and tear such as deep scratches, punctures, and regularly result in failed prints. Some can get at least 20-30 prints, though with proper care, FEP sheets can last several prints without damage.
Is SLA or SLS more expensive?
SLA printers are much more affordable. You can easily get one for less than $500. SLS printers, on the other hand, can cost you a minimum of $5000. However, the resins can be relatively expensive while some materials for SLS printing such as Nylon can be inexpensive.
What is SLS for 3D printing?
Selective laser sintering (SLS) is an industrial 3D printing process that produces accurate prototypes and functional production parts in as fast as 1 day.
