Printing a transparent cube  

RE: Printing a transparent cube

Only idea that comes to mind is use a resin printer.

I think the best you are going to achieve with FDM is translucent.

RE: Printing a transparent cube

There is a filament and system out there that promises clarity.  You print something then set it in a chamber that vapor washes the part to melt the surface to a smooth and polished sheen.  It's been mentioned a few times here, but the name of the filament escapes me.  Do a google search for glass filament...

For walls, something like Polymaker's Polysmooth filament might work. It prints much like PLA but can be smoothed with isopropyl alcohol. Anything with internal infill is going to be difficult to make transparent.

If you do find something that gives good results - post it!

RE: Printing a transparent cube

Thank you all for your replies. It's a shame that there isn't a common way to do this with FSM printers but I'll keep trying and I'll definitely report back if I have success.

I tried Polysmooth but as bobstro said it's only for thin walls.

RE: Printing a transparent cube

As long as the printed part has infill, I wouldn't expect to get any real transparency with FFF printing. I have sent some experiments in which epoxy was injected I to an otherwise sparse infill that gave more of a transparent result, but certainly not glass-like.
