How to print small PLA patterns on glass?
Hello,
I would like to 3D print some small PLA patterns (each looks like 0.5 mm x 0.5 mm x ~25 mm) on the surface of 1" round, 1 mm thick fused silica substrate (see model attached below)? I have multiple Prusa 3D printers. One I use often is Original Prusa i3 MK3. How can I do this? How should I hold the fused silica substrate on the magnetic printbed? How do I set the printer? Thanks.

You could try double sided tape or glue stick to hold the material down. You may have to modify the g-code for the first layer to be at the correct height. Go through the code looking for all the G1 Z lines after the wipe. Add in your 1mm offset to those numbers.
In one of my models, the first line after the wipe is G1 Z.6 F720, I would change that to G1 Z1.6 F720, once the print head gets to the point that it is going to print, the command G1 Z.2 F720 is sent. This would be changed to G1 Z1.2 F720. If I was doing this, I would look at using a script to change it. Could be done in a text editor with search and replace features. Start with the highest Z point first if using search and replace.
Ensure the article is not in the path of the bed levelling or don't do the bed levelling. I would test with some test printed pucks.
