For this project, I would like to explore the possibility of combining two advanced techniques, printing transparent with FDM and printing flexible/kinetic pattern

Part 1: GLASS FDM!

Inspired by this video made by youtuber CNC Kitchen, which is based on parameters posted in a forum, I decided to test these parameters he

Research Outcome

PETG/PCTG is a feasible and common material for transparent printing but its overhang is simply not good enough for me to make this project. It’s also not as clear as I would like it to be. There is a type of PETG that’s printed in a higher temperature (ColorFabb Clear HT PETG) that would actually make optically clear results, but my printer’s nozzle cannot handle the temperature.

The PVB

Important settings for a GLASS print:

• 100% unidirectional linear infill
• Low printing speed (down to 15mm/s)
• Higher Flow/Extrusion Multiplier

The materials for transparent FDM printing are always printed in a higher temperature for a slower curing speed resulting in a better flow which eliminates bubbles that fog the print.
