YOYI YOYI Flexible 95A TPU 1.75mm 0.5KG, 3D Printer Filament Black

Still a beginner, and so far it's been working on my A1 granted I've only tried simpler designs. Initially I had stringing with the generic profile, but after lowering the temperature, fan, and speed the prints are much better. TPU reminds me of polyurethane bushings, it's plasticky but has some flex and a hint of grip. Overall I think it's worth a try or at least 95A to start with.

This filament initially worked well out of the box. However after printing about 1/8 of the spool, it would no longer feed properly. I then measured the diameter of the filament and it was 1.25mm instead of 1.75mm. I can only assume that initially the diameter was correct which is why it would print but they clearly have an issue with quality. I will avoid this filament in the future. Update: After this review was posted the seller reached out an offered a full refund. Since the seller stands behind their product I have changed the rating to 3. I plan on using the refund to purchase another roll of this filament and will update my review based on how well this new filament works. Update2: Once I was past the bad portion of the filament the diameter returned to the correct size. I have now been using this filament for some time now and have found no further issues so I am raising my rating to 4 stars. However, their extrusion process should continuously monitor the diameter and should not allow bad patches to pass but perhaps this was just an anomaly.

It would be even better if this product could be launched in a matte version.

Good

Decent TPU. Does what it should.

Why did I give it 4 stars? It's because it wouldn't stick to my glass bed. It also doesn't stick to carpenter's tape or maybe my carpenter's tape is bad. I applied purple Elmer's glue stick on the glass bed and it started printing well. I didn't have to do that with Overture and Sainsmart. So far, it's printing really nice!

Okay, so the filament prints and looks great, but the cardboard spool arrived so damaged that I could not install spool rings and the spool hung up in the AMS over and over interrupting many prints. No other items in my order arrived damaged, so thinking it must’ve come from YOYI like this. I may try again, with fingers crossed.

Decent product.
