Replacing the silicone layer on the B9Creator UV resin printer
When 3D printing with the B9Creator, UV resin is cured layer by layer with the help of a projector and so turned into a shape, which is lifted out of the remaining still-liquid resin after the print. So that the resin does not bond with the acrylic glass print tray (called the vat in the manuals) as it cures, a coating of silicone (PDMS) is used. Unfortunately this breaks down after a few prints and therefore has to be renewed regularly.
