Summary After several attempts to control the surface tension, finally I have a system that works properly ti print on 100,75,50,35,20,10 microns. This system can be found only on hi end professional printers as Ultra by EnvisionTec. Forget the problems caused by surface tension, such as bulging effect and others. This vat are made of 3mm and 6mm transparent and white acrylic. Barrels are made of 8mm. stainless steel. Construcion plataform its made on 5mm aluminum. Other hardware are printed on FFF printer on PLA filament. Only require drilling 4 holes in your printer to assemble the entire system. The self-adhesive film with teflon for the vat cap, I bought to guys of Muve3D . http://www.muve3d.net/press/product/fepteflon-non-stick-reservoir-coating/ They have an instruction of how to put it correctly I leave here the link for you to download the original file. It is made on Rhinoceros but leave a copy with .dwg extention. So you can measure all the elements to determine where to make the holes on the back of your printer. https://www.dropbox.com/s/353abkm3goq1w7s/NEW%20SYSTEM.rar?dl=0 http://youtu.be/WGl24ju_1yo https://www.youtube.com/watch?v=vRaSqutYaf8&feature=youtu.be
