Build Your Own SLA/SLS

Hi guys, got a problem and I need your help please. Recently I got a pretty bad details loss on my prints. I have FULL HD DLP, Optoma HD25e, 2800 luments, 20000 contrast, lamp 300 hours used. distance to vat is 28 cm. I'm using MakerJuice SubG+ resin Black and Red with some added PI. Focus is set pr...

Alright, thanks a lot :0

Well actually in general terms on your DLP gyus, what's the contrast and brightness set from 0 to 50 for example?

I couldn't do anything except for increasing cure time, but this unfortunately will probably burn your center area of th...

This is called INTERSELECTED SURFACES.
Solution is to handle it in any 3D software like 3DMAX or ZBrush manually via Boolean operations,
or some software which will repair (fix) this some kind of like NETFABB, etc.

Hope this helps.

Why not, it seems to have the same specifications, so I think it will work.

Hi guys, 1st of all I'm e-x-t-r-e-m-e-l-y grateful for your responds, I hope this topic will clear things out to me :) finally! Yes, I'm using 23-FEP-TEF Dupont Teflon w silicone (adhesive) from CSHYDE. The sounds of detaching are awful, I will try decreasing the speed of my LIFT UP, thanks for the ...
