Update 11/9/17: Improved substrate vacuum mount to minimize filament sag, improved vacuum channel, and improved stiffness. The outer diameter of the mounting tube is sized at 6.8 mm to account for printing coarseness. This will mount to the standard 6.6 mm vacuum actuator pen with a little turning. If it takes too much effort to mount, I would suggest lightly sanding the mounting tube. Print face down on glass (for glass like finish on the working side) with 100% infill and 100 micron layers.
Vacuum wand for handling ~2-6" silicon substrates.
Materials to print in:
PETG will offer good solvent resistance but not acid resistance
ABS has mild acid resistance but poor solvent resistance
Polypropylene is probably the best material, but not strictly necessary for most applications
PLA is probably not a good choice here
Update: 8/21/16 Slightly taller vacuum channel to compensate for filament sag.
