Experiments with T-Glass. Initially, I had real trouble printing with this but when I totally ignored the included instructions it went much better. I had to go up to 246 degrees in temperature (230 for normal PLA) and print at 40mm/s. I am printing in a rather cold garage. Printed on an @Ultimaker 1.
The coffee cups and bracelet is printed at 0.2mm layer height and the frog at 0.09mm.
The white cup is for reference and is printed in Pearl-White PLA.
T-Glass seems like a great material to print with.
The coffee cup is of course designed by our own @Daniel_Noree !
The filament itself is apparently FDA-approved. Your extruder will, of course, never be certifiably food-safe, but I’m sure people have taken drinks our of printed cups made with every 3d printing filament available at one time or another, and I haven’t heard of any of them dropping dead or growing extra limbs as a result. YMMV.
Interesting to see that the roughness in the extrusion is still there with an Ultimaker. I’ve been getting the smoothest extrusion lines I’ve ever seen with the Bukito (especially last night, when I tried T-glase on it), and one of our hypotheses was that the bowden tube was smoothing out the extrusion by allowing some slight variation in the length of filament between the extruder and melt zone resulting in the nozzle pressure being more constant, but the Ultimaker has a much longer bowden tube that should make the effect even more apparent. Looks like super-smooth X/Y motion must be the cause…
I don’t know if rough is the right word, but there’s an unevenness along the length of the extrusion, mostly visible as a difference in the transparency of transparent filaments, especially T-glase. I’ll have to get some pictures of it when I get back to the shop on Wednesday. I went years without noticing it, but after seeing some of my prints off the Bukito, I can’t not see it in other prints…
It’s pricey, and I’m not sure what better sizes then the 1lb roll I got there might be, but the dimensional accuracy on interlocking parts is impressive, as well as the strength. Mildly flexible, qualitatively less so then ABS
Nice results. I had a bit of bad luck with my batch of t-glase, it turned out to be oval and jammed my extruder massively. It turned out to have 1.55/1.95 instead of 1.75.
@Peter_Parnes in the second photo there appears to be some black horizontal lines, is that an optical illusion? Or is it burnt filament or residue from a previous filament?
