Hello, We have been using transparencies for almost 4 years now. We use them for photolithography with SU8 2000 formulations and the minimum feature we have fabricated was 10-15 microns (for microfluidics). However, we do not have our own printer, we send the autocad files to a company that prints them for ~70 USD per sheet (you can fit 6 3in x 3in masks). Hope this helps, Octavio > Hello all, > > Our group was thinking of printing our own masks on transparencies instead > of using expensive chrome-glass masks. > > Has anybody had success using printing for creating masks? > > If so, what type of printer was used? and what was your minimum feature > size? > > Thanks in advance, > > J.
