Build Your Own SLA/SLS

And what software do you use to hollow your parts?

Did this ever get resolved? If so what was the solution?

Francesco,
mUVe uses the Viewsonic PJD7820HD. It is proven for this machine and makes it easier to get advice from those who already have one.

I'm in too...

MJ SubG+ Red. Same with SubG+ Black. I reset all the settings to factory on my projector. I did just get some new QSil and will try my old glass vat to make sure something else didn't go amiss. But for now I need to make parts and it is working great (just slow).

When i bought the FEP I did not know there where different types and their description does not designate which they sell (no adhesive): -Color: Clear -Temperature Range: Plain Back: -320° to 400° F, Adhesive Back: -100° to 400° F -Tensile Strength: Poor -Impact Strength: Not rated -Width tolerance ...

Good questions. I am on a search for the best FEP (or similar) film and am finding that the manufactures of these films make them in different grades (translucent, clear, etc.) which, I am sure, greatly changes the UV transmission. My film from McMaster seems to not transmit UV as well as what other...

FEP is tough stuff. I accidentally drove my Z home with a 15mm diameter printed shaft on my build plate (again). By the time I could hit the power switch it had driven about 25mm into the 0.005" FEP. It permanently deformed the FEP but did not break through.

HP, thanks for the info. I love your vat designs, I'm trying to hard with my tensioned vat. ;-) Hopefully my long exposures are due to my FEP. I'll try to get some from Alibaba. One thing I just ran into -- I was having an issue with the part not sticking to the build platform and I solved it by add...

HP,
Thanks for your assistance. Looks like I may be buying some more FEP. What exposures are you using and what is the biggest part you have printed with your flex vat?
