This is another tutorial:
He prints large items. Very large! So of all people, he would be one who would seem to need the tilting peel, but he doesn't. The FEP in his vat is flexible enough to lift within his frame even when his frame is held solid. The FEP is not "drum" tight as you see in the mUVe flex vat.
If you check his videos, he has another that explains in detail how to build the tape vat.
His design is very nice, but I don't like the idea of having to use a fused filament printer to make a frame. I was planning on taking a trip to a local hardware store and looking around for some common item that can be used as a frame. Perhaps some kind of ABS toolbox, or perhaps a small bathroom garbage can. I am also thinking of Michaels arts and craft store and looking for some kind of square acrylic dish or picture frame. Anything that looks to be an appropriate size where you could cut out the bottom and stretch the FEP across. I have a CO2 laser cutter and a CNC mill, so putting a good square in the bottom of an acrylic dish will not be a problem. With the laser cutter I could also do a hybrid of James' design where I can put pins on the square frame and laser cut holes in the FEP so it can just be stretched over and catch on the pins.
Realize also that if you are cutting a square out of the bottom of a dish to make an area for the FEP to stretch across, you could reuse this square to be the firm backing that is required. You would simply cut the square about 1/4" smaller in all dimensions and you would bolt your vat back down the the print bed over this square. This gives you the solid base and also stretches the FEP a little more in the area you need stretched.
If I find the right dish for a simple tape vat, I'll be sure to post the part number and where I purchase.
I want to build my machine using a single stepper on the Z axis and no motorized tilting. This will let me use the Raspberry pi with NanoDLP software, but avoid the arduino and Ramps board that so many people seem to be having difficulty with failing communications.Statistics: Posted by lasersafe1 — Sun Jun 05, 2016 11:07 am
