Evening all,
Been musing whilst tuning the huxley..dangerous...

John S has a laser cutter, will do plastic cutting and engraving, has a height adjustable bed to set the laser focus.
All it needs is the bed automating, a powder spreading system, and a source of powdered plastic.
Voila! Selective laser sintering printer

Thoughts?

I think there are some doing that with powdered metal already.

Fusing a plastic powder into shapes is an old process by now.

SLS has been around for a while. People have tried it with the cheap lasers but almost no one makes a laser cutter with a controlled Z axis. Mine does as well as the laser welder I am getting.
