Thoughts about taulman Tritan so far...

[jeffhuber]

I got a couple rolls of taulman Tritan to play around with. I was really attracted by the mechanical stats (6600 PSI tensile, and 53,000 PSI modulus) and it also does not seem to have water absorption issues like the nylons. Tritan is a polyester. My findings:

- tritan is insanely strong. the parts are the hardest parts i have ever seen come out of a 3d printer. and that includes printing some polycarbonate as well.

- bed adhesion wasn't obvious... but i ended up getting it to stick with 90c bed, hairspray (aquanet brand), 115% flow rate on first layer at 15mm/s with a 8mm brim. once the bed cools down, the part pops right off.

- you will need to upgrade the stock hot end to do this - im running at 282c on the e3d v6.

- jamming issues - i did encounter some jamming issues, but it's hard to place why. the rolls of tritan i got were a little under spec (around 1.5mm diameter). I wonder if the tension on the extruder would sometimes slip or not be strong enough to push it through. i do prefer 1.5mm to 1.9mm though!

- Tom at taulman has been really helpful and supportive! he's a great guy!

Here is a picture of the biggest part i was able to print. (part of a prosthetic socket)

have you tried tritan? what have you found? especially interested in ideas to avoid jamming.

I've really wanted to try Tritan out...how has it been with shrinkage/warping?

[jeffhuber]

warping isnt too bad. i would say less bad than abs. shrinkage i havent done an empircal test yet. I doesn't seem bad at all. According to the spec - http://taulman3d.com/tritan-spec.html - it's .0021" per inch
