SLS Printers Are Getting Cheaper

Here is a kickstarter that puts SLS at around $7K USD

They already produce an FDM printer so this may be a bit safer than a lot of those "I have a dream" kinda companies. Absolutely no word on how they recover unused powder, which is vital in making these printers cost effective.

Sinterit also lowered the pricing on their Lisa printer to about $6K USD

This printer is already available and has been in production. Their powder recovery process is completely manual but they do offer a sieve to make mixing the used and unused powder a bit easier.

 

I dont believe they do

Seperate system "if you want it" that can be bought else where for now

I talked with them and their main suggestion was by hand as well lol
