SLA Printer FDM Parts

thingiverse

These are the FDM printed parts used in my ongoing SLA build project, which remains unfinished and non-functional at this point. Full build notes #1: https://kt421.wordpress.com/2015/06/28/my-newest-project-an-sla-printer-wip/ Modifying a projector: https://kt421.wordpress.com/2015/07/07/modifiying-a-dlp-projector-for-use-in-an-sla-printer/ These parts are specifically designed to work with the materials I have on hand, which include the gutted remains of my Printrbot Simple Maker's Kit after upgrading to a Printrbot Simple Metal. All FDM parts printed at 0.3mm layer height, either 10% or 30% infill depending on whether the part is load bearing or not. FDM Parts in this project: Mirror Bracket (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, and the mold is slightly 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 (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) DLP Projector Aluminum build plate (http://www.metalremnants.com/product/aluminum-discs/) 2x 8mm Smooth rods (PB Simple) 5/16" Threaded rod (PB Simple) 2x LM8UU Linear Bearings (PB Simple) M3 hardware (PB Simple) Delrin Acme Nut (PB Simple) Servo for shutter Firmware/Software: Marlin; modified to remove extruder code and temperature failsafes, and to enable 1 servo 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, which will literally melt your printer. I'm using PLA because I have lots of it; if needed, I'll reprint parts in PET or Nylon. 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 modify it a bit to make it work.
