HATCHBOXTPU 3D Printer Filament, Dimensional Accuracy +/- 0.03 mm, 1 kg Spool, 1.75 mm, Shore 95A, Black

siempre me va muy bien con esta marca la recomiendo mucho.

Let me be clear, printing TPU for the first time is not for the feint of heart. I've successfully printed a small model but so far larger items, not so successful. Going to take a bit of playing and tuning of the slicer and my Creality CR10 s5 to make it consistent. The material STICKS to the glass very well, almost too well - playing with my settings may help there. It seems to be good value for the money but only one I tried. I got ONE really nice print of a small sample only after several attempts. I'll get there, be nice if they had "suggested settings" for different printers. No retraction helps, slow speed as it will bunch up on you in the feed mechanism as you are pushing a wet noodle. Temp a little higher than pla to keep it flowingSlowed down the printing speed and that by itself did not help. Slowed down the X/Y axis movement speed to match seems to have done it. Before in larger print was getting a spiderweb effect for the projects, now it looks really sharp. There is a great youtube vid from Angus of Makers Muse that helped a lot.

En lo personal, no me gustó su acabado, es un TPU muy blando, dependiendo de la pieza puede que se rompa muy fácil en áreas delgadas. A pesar de que viene sellado al vacío al parecer el mío venía húmedo porque presentó los síntomas comunes de humedad en filamentos.

First off, I'm a normal customer. No weird discount stuff. Idk why hatchbox does that, throws off trust(at least mine).Anyway, Great fialment! Hatchbox has been my goto filement since I starting printing. I've bought over 7 rolls of pla. It's high quality stuff, and this TPU doesn't disappoint. Naturally, it's a bit more stringy than pla, but nothing problematic. It looks like pla until you touch it. It is also very easy to print and it prints at the same nozzle temp I use for pla (210c). I print on a PEI sheet, and since it bonds way too good with it, I have to out gluestick so as not to damage the pei when removing the print afterwards.I also print with 0 bed temp(pei holds extra well, though with glass you could prolly still pull it off, or at the most, like 50c). I print a little slower at 15-30mm/s depending on part.Check out the images of a pyramid I printed.Hey hatchbox, instead of giving free stuff to get reviews, you should give stuff to real reviewers/customers :)

This is my first TPU material so I have nothing to compare with. However, my first TPU part was run with standard PLA settings and it printed just fine. My second print was a temperature testing box. In deed, this filament likes to be extruded at colder temperatures. I started with 230C and dropped to 210F at a height of about 1 inch or so. The upper part of the test was much more consistent than the hotter temperatures. This filament is pretty sensitive. It will even bubble at 215C, so try keeping this filament at around 210F. I haven't done a low temperature test yet, but this is where I keep this filament.As far as print speed, Quality doesn't seem to vary much between 30m/s and 92m/s. However, you can't push this filament any faster than that. I've pushed the filament from 100-200m/s and it fails to extrude. You can increase temperature and extrusion rate, but that will only bunch up the filament inside the extruder and you'll have a bigger mess on your hands. Why 100-200m/s speed? Well, I do lots of test prints and prototypes, and finish is of no concern. I print prototypes at about 200m/s, and this filament can't be pushed this fast. Keep it below 92 m/s.You can cut this filament with scissors. Why is this important? I have a Makerbot with "Smart Extruder" and the heat block is encapsulated inside the extruder body, and this filament can roll and curl up inside. This is a dangerous situation. Make sure the end is "square" and straight before loading this filament.Beware of loading and unloading precautions. I frequently change filament and this filament is a lot trickier to load and unload, so it's not load/unload friendly.Otherwise, this filament is pretty nice.
