Even though the title says SLS, focus is convertible to 3DP (inkjet). Nobody has gone into SLS desktop printers because it is unknown, really hard and dangerous (high powered lasers). Powder management could be a health issue, but I think it is mainly this: no real prospect for usable parts in experimental printers and too many unknowns. (for SLS and 3DP)
I haven't had a single usable part, just some experiments. Everything I do is completely unknown.
I am currently planning to convert Focus to 3DP printer, because I need a break from the hell that is SLS printing. I need to rethink SLS before I will continue with that.
