These are the FDM printed parts used in my WIP SLA build. It's currently unfinished and non functional.

These parts are designed for the materials I have on hand: the gutted remains of my Printrbot Simple Maker's Kit after I upgraded to a Printrbot Simple Metal.
All FDM parts printed at .3mm layer height, either 10% or 30% infill depending on if the part is load bearing or not.
FDM Parts in this thing:
Mirror Bracket (only one side, mirror it in your slicer for the other side)
Z assembly
Motor Mount & smooth rod block
Knurled knob (unmodified from source)
Z-coupler (unmodified from source)
Vat walls
Gasket Mold (I used RTV gasket maker to create the gasket. Mold is lightly larger than needed as I found the gasket maker shrinks.)
FDM part yet to be designed:
Shutter for projector
Vitamins:
MakerBeam kit
RAMPS/Mega
Nema 17 motor (PB Simple)
Vat (cut from acrylic if you have access to a laser cutter; otherwise use the STL above to 3D print it)
Vat bottom - FEP Film
(http://projectsinterestsandetcetera.com/store/) or potentially Reynold's Oven Wrap?
Small C-clamps to hold vat assembly together
First Surface Mirror (http://www.sciplus.com/p/MIRROR-FIRST-SURFACE15MM-X-15MM-X-1MM-THKVERY-SMALL_248)

Creation Workshop to slice and control printer (http://www.envisionlabs.net/)
WARNINGS:
DO NOT USE ABS FOR SLA PRINTER PARTS. If you have a resin spill, the resin dissolves ABS. It will literally melt your printer. Not fun. I'm using PLA, because I have lots of it. If I need to, I'll reprint parts in PET or Nylon. I'll update this if PLA doesn't work out for any reason. Likewise, PVC is not a good material. The PVC vat in the pic is just a placeholder while I make my acrylic vat.
You'll have to get a DLP projector and likely have to modify it a bit to make it work. Void warranties at your own risk.
