SLA Printer FDM Parts

thingiverse

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