you can basically treat it like a thermoplastic with a really high melting point

problem is that

glass doesnt behave

a really heavy thermoplastic

like plastic

It's still semi-solid even in molten form

this is also true of thermoplastics

if your plastic is going down fully liquid you're printing _way_ too hot

i'm not even sure how you'd manage that without burning it first

The thing is that glass seems like it would need a fuckton more heat

it definitely would

before being finely printable

like Tungsten hot

that and the rigidity of cold glass are the main issues you'd need to tackle for a glass printer

you would definitely have to print in a heated chamber

for sure

you aren't gonna print glass off a normal printer, just

it'd be closer to a normal fdm machine than a clay printer would

oh i realize

What're the best materials you can use for FDM

without ultra specialized equipment

depends on what you want

nyon is great for most things

The way i understand it polycarbonate and nylon are up there

what about glass-reinforced versions of those

or TPU

FRN is doable but you'll need to replace your nozzle every print

and possibly during a print

i use TPU fairly often

TPU seems fun since it's not strictly rigid

you will not get a smooth _and_ dimensionally accurate surface finish from tpu without some really dangerous "no normal person should own this" industrial solvents

so just be aware of that

also support structures are horrible pain to remove and will never come off cleanly

sanding and grinding the stuff smooth is next to impossible

You could fix that

with a double extrusion print

where the support material isnt tpu

more difficult than it soudns

But the solvents part seems kinda offputting

if you don't care about dimensional accuracy you can polish it with a propane torch
