Demolding Procedure

Tip 1: Print 2 sets if possible

The forming tool will last longer if you allow it to cool between formings. If you print 2 or more tools, you can keep forming for hours by alternating tools between cycles.

Tip 2: Form multiple items at once

Form 2 masks at once


Tip 3: Have a spray bottle or a wet rag on hand

The sheet clamp/frame and the perforated mesh will heat up if you're forming continuously. To quickly cool down these components, spray them with a mist of water or wipe them down with a wet rag.

The evaporating water will quickly wick the excess heat off of them.

Tip 4: Use a mold release agent

The hot plastic sheet has a tendency to stick to the 3D printed forming tool making it difficult to demold. To make it easier, slather the tool with a generous amount of petroleum jelly, or even vegetable oil.

Too big or too small?

Scale the STL up or down to resize. Or better yet print several tools in different sizes.
