My first two test prints with one of @Tom_Martz 's (aka Taulman 3D’s) new filaments, Tritan.
They were printed at 270c (!) on a garolite bed at 90c. They both had good bed adhesion, but were easy to pop off the bed when the temperature got to about 80c. There was no apparent warping away from the bed surface.
The single walled test cube shows the excellent translucency of this stuff. You can even read through it. The rook was printed with my previous setting of 3 perimeters and 25% infill, but would probably give better translucency at 2 or even 1 perimeters. Interestingly, the translucency has made my belt-rubbing caused surface ribbing extremely obvious. You can’t feel it, but with Tritan you can really see it.
Tritan seems to give very little warp or curl during printing, the only time this wasn’t true was on the steep overhang at the top of the rook, but this print had no active cooling going at all. A small amount of that would probably help immensely and prevent that minor curling. I did get a little stringing with it, but it all cleaned off very easily with just my fingers, no cutting needed. The bridge on the bottom of the rook turned out only so-so, my PLA/ABS setting is overkill for Tritan and the bridges sagged. Turning down the bridging multiplier should fix that, though the results were good for an uncalibrated first print.
As for strength… this stuff is tough. Squeezing as hard as I can on the crenelations at the top of the rook produces a small amount of deflection, but no damage. I can’t break those things off no matter how I try (and anyone who has printed this model in ABS or PLA will know, those things break off without too much work). Squeezing the rest of the model produces no deflection at all. This stuff is more rigid than, and at least as tough as, nylon.
Color me impressed.
