All the best.

Sprinkling a powder does change the surface texture, much like it does on Pt silicone or TPE toys. (I've used baby powder, but powdered sugar should work, too). If it's the appearance, rather than the texture, that you're interested in, then I'm not sure how sensitive this is to the amount, composition, and grain size of the powder. I can confirm that the surface will have a more "matte"-like appearance, in 100% of the one trials I ran.mi6c wrote:I am not aware of the sugar sprinkling for a matte look - like with silicone surface creation - if that is so it would be nice to get some reference.
The cure time for 3D-XTC is HIGHLY dependent on temperature. In theory, the reaction rate should increase exponentially with temperature, and this is consistent with my results with both 3D-XTC and every other 2-part epoxy I've tested. If you do want to use XTC but need more time, you can cool it down to to ~50 F before mixing. Obviously, this makes the mixing process more difficult. It does work, though, and any bubbles you trap should disappear when you spread it on your print. If you can cool it fast enough, mixing then cooling works, too.MannequinFan wrote: On second thought, the high build primer may be the better way to go for a project this large.
You only have a few minutes work time with the XTC so you'd probably end up having to do it in sections.
