Open Source is a Philosophy, Not a Checkbox
TL;DR : open source is a philosophy, not a checkbox. Find more collaborators, not customers. The future is open.
for sugar we usually do 1.2 mm or 0.8 mm for reproducible extrusion. Going smaller requires higher pressures which the glass syringe won't support. you can't just increase the temp. to lower viscosity because the sugar will burn.
And a steel syringe is around $500 to start with, so we'll stick with the $50 glass syringe for now.
Hey Jordan, how small have you gone with your nozzle diameter?

are you using standard borosilicate hamiltons then? have you tried fused silica (quartz) instead?
