Re: Stereolithography machine

For the UV cured resin machines you lower the working bed then top up,
it can't be overflowing (although it can overflow oncce each time).

For laser sintering they seem to use a gantry that lays a layer of the
fine poweder and then levels it with a squeegy. It is tempting to try
with some toner and a 2W diode from ebay.

if you use a gantry system it is going to be increadibly slow you will
probably want and need quite a small spot size so for each layer it
will be necessesary to raster scan the whole area. Even if you make a
fast gantry system (say based on a plotter) it will take forever. If
you really want to make small parts I guess that would be OK.
