Review on 🖨️ SainSmart Flexible Printing Filament: Advanced Additive Manufacturing Products and High-Quality 3D Printing Supplies by Viswanath Lopez

I will keep trying but at least twice in the first half of the first roll I bought, the diameters increased by more than 2 mm - see photo of the second example. The first was over 2.2mm. It's stuck in my printer (Flashforge Creator Pro). And since you have to print this material very slowly, a 14-hour overnight print will naturally jam after 10 hours. I look forward to improving my rating once I'm through the second half of this role and the second role. I may or may not get a usable print for $54. If you really need TPU/TPE this might be a safe bet, but keep a close eye on your printer and if it gets stuck, stop, throw away all the bad prints and filament (it was only about 5 inches in the first jam, two inches in the second) and start over. I think if I had known this beforehand I might have tried another provider. But this company usually has good filament - no problem - so it's possible they just had poor mileage. The temperature and speed are finicky as others have described, but if you use the right settings and it doesn't stick you can get good results. . If you type too coolly or too quickly, you end up in chaos - the outer walls don't fit, sloppy support structures, rough curves, demarcation. I used similar settings as another commenter: Extruder temp: 220°C Bed temp: 60°C Glass and hairspray cutter: Simplfy 3dSlicer settings: Default print speed: 30.0mm/s (1800mm/min) First layer height: 95% First Layer Width: 120% First Layer Speed: 50% Slower Outline Speed: 30% Slower Solid Fill Speed: 35%
