Hi guys, yes I understand completely the benefits of SLS. My projet was a polyjet printer printing wax as a support and acrylic as the build material. It was also not limited by part geometry. I've never owned a glue gun on a gantry. lol I did make an error in my rant. The rims are only 27mm diameter x 15mm tall, so a build area of 110 x 110 x 100mm would allow me to print 4x4x6=96 rims... At $5 each is starting to make more sense.

I saw a sandblaster mentioned and was thrown because I couldn't figure out how to separate the silica sand and the build material. Now I think they only meant the enclosure to trap all material and any dust.

I think I'm going to have to get on board...
