Does Buildtalk have a much better sticking quality than painting mask ?
I had printed with painting mask, the result was not bad at all...
If I want to change to buildtak, it means I need to recalibrate the Z limit again.....don't I ?
I would say it's definitely more adhesion than with tape. It's only marginally better than tape, though. If you really wanna upgrade, look at a nice thick PEI sheet. If you get the 1/8" thickness, you don't need to glue it down to anything, just clamp it to your glass/flat bed.
The limitations of buildtak are that the surface is very delicate and the sheet will peel up during the first large ABS print that would otherwise normally curl up.
