Review on 10-Meter Filament Temperature Change: 32°C (8 Feet) by David Stewart

UPDATE: I just bought a gray PETG filament from Yousu. I really liked the black, but the gray is very viscous. Continues to build up around the nozzle and then leaves clumps on the print. This is at 235 and when printing at 80 mm/s. I don't know why gray isn't as good as black. I'll probably try another color because the black was really good. Definitely a star deduction for the stiffness. I really like this thread. I used to use Inland PETG but had issues with adhesion and stretch even with the retraction set at 4mm. The first print with this thread was very good. Very clean except for a lot of strings in the supports. However, the piece itself was very smooth. I also forgot to set the retraction and it was set at 1mm hence the tension. The second print, set up correctly in Slic3r, produced a near-perfect first layer without a hint of tension. The pressure really came out. The best I've ever had with PETG. One more thing. The spool is slightly wider than standard spools. I was afraid it wouldn't fit on my spool holder. However, the coil has an inner tube that fits my mount perfectly. Nice design. I am very happy with this material. It is very durable, has a nice finish and extrudes very smoothly. I will definitely buy this item again.
