Build Your Own SLA/SLS

Support / standouts if your using a perforated build plate.

@adambx The underside is dotted from my build plate holes. This is a top down setup so no release.

@kakapoopie Yes curling is a b*** with these little machine and large pieces. I am working on a little trick to combat it. I will let you know when I get a little farther with it.

I am using the top down method. It seems t be caused be some sorta of pressure do to closing all walls i.e. tube. I am seeing it in other parts with similar structure. The resin seems to want to move in and out of closed structures.

Learned a ton working with this model in its solid form. Made with G+ red at .12mm z and 100xy.

Does anyone have experience with holes forming in sidewalls on top / down setup? See picture any tips appreciated driving me nuts.

@bobbitay its probably only a matter of time then before I add one especially if it can speed up builds. I will work with the software for now and report back results.

@Bobbitay I am avoiding a wiper for the time being. To be honest I still am unsure what it does. Is it just to speed up large surface coverage?

My cure times are 9 seconds right now so the ripples tend to level as it cures.

Soap cuts surface tension for consistent level. No soap in contact with resin I'll post pic when I get some time.

@kakapoopie the column works in my favor because i have an overflow reservoir. So yes every layer displaces but build height stays constant.
