Filament Flexible D3D Sigma TPU 1,75 mm - Bobine de 500 g (5 Couleurs)

Great place great help Everything I need and experience have been going here for years

Beau filament

Strong, tough and fairly easy to print using the recommended temperatures and fairly slow volumetric speed (6 cu. mm/sec). The attached picture is a drive belt for my drill press -- doesn't slip, doesn't heat up. I've also made a number of gaskets and seals (150psi water pressure with no leaks). This stuff is a game changer for me.

I bought and tested a roll of the green Sigma TPU: great stuff. Got all the settings figured out to work with my open bedslinger and made several functional parts with great success, from gaskets and seals to a drill press drive belt. So I bought a roll of the black, thinking it would be similar. Not so much. Right out of the vacuum sealed bag w/dessicant I had stringing, under-extrusion and poor layer adhesion. Every print failed. I tinkered with settings for hours without success, but I could print the same parts in green (which I store in a vacuum bag with dessicant) without issue. All the signs were pointing to excessive moisture in the filament, despite coming direct from the factory packaging and ambient 35% RH in the room. So I stuck it in the warming oven at 70° C. After drying overnight it seems to be printing reasonably well using the original settings determined using the green.

Nice , Just needed to get the right temp ... I upgrade my noozle block heater to copper and make my temp 205 and 60 for bed and works good. I always make design for cellphones cases .

Prints well. Durable. Vacuum belt has been going for months.

First time printing flexible material and wasn't too hard to dial in. Had to modify my extruder a bit (had a huge gap, material curled up at extruder), but once that was done, it printed and adhered very well at 220C/55C on a modded MPSM.

It's nice to have this available in a smaller spool size. TPU isn't something I use a lot, so when my uncle wanted some caps printed in 3 different colours, it was nice to find someone selling it less than the standard 1 kg roll of each. Performance-wise, it's pretty similar to every other TPU I've used; it's flexible, tough, and has a decent surface finish, but stringy, oozy, and not easily sandable.

The toughest portion when printing with TPU/TPE filaments is, first, the tacking on the bed. I had to cheat with some tape to have the skirt attached on the bed, and even then, I had to pause the print to re-attach (with more tape) the base of the print on the bed. So, if you manage to find the right settings on your printer (mine was 220 celsius, and 70 for the bed, with some PVA glue on the bed (but it didn't quite work)), and at the end, after some reajustements, it prints well. I printed a Baby Yoda, but forgot to put rafts under the overhangs, but printed surprinsingly well. The flexibility of the material will depend on your filling percentage, mine was about 18%, but I found out it was a little too much for the Baby Yoda. Next time I successfully print with this, I will post a picture.

I have to print very slow but it works every time love it.

Good quality and no issues printing on Anycubic i3 Mega. Really pleased with the product.
