HATCHBOX 1.75mm Orange TPU 3D Printer Filament Shore 95A, 1 KG Spool, Dimensional Accuracy +/- 0.03 mm, 3D Printing Filament

Love hatchbox and I order it all the time.

There was a little bit of a learning curve on print settings but once I got it. Dialed in it prints like a champ.

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.

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.

This is my first TPU filament and I'm very happy with it so far. I'm using it in my Prusa i3 MK3S+ and have not had any issues printing. I'm printing directly on the textured sheet, but they advise putting something like a glue stick down if you have the smooth sheet. I also followed the Prusa guide for printing with flexibles and loosened the idler tension on my extruderI'm using the Prusa SainSmart TPU profile and there is some minor stringing depending on the model, but not sure how much that can be helped with a flexible filament like TPU. I haven't played around with retraction at all yet and am using the profiles default of 1mm. Perhaps increasing this a bit could help the stringing.

While Hatchbox is definitely a budget-friendly manufacturer, I've been fortunate to have had almost exclusively positive experiences with their PLA filaments...when I decided to get into TPU, the price and availability was right for me.Like with all the Hatchbox filament I've bought, it came in a very well vacuum-sealed bag with a big sachet of silica gel. The winding appears to be good (this was my only previous issue with Hatchbox), I've noticed no moisture issues, and it feeds well into the Micro-Swiss direct-drive extruder and hot end kit on my Ender 3. The first few prints, small calibration type items, went pretty well but I had to do some additional tweaking to get larger parts to print without issue (definitely check the flow/extrusion multiplier because it will feed differently than PLA/PETG/ABS). Once those tweaks were applied, however, the issues I had with print quality and filament not feeding correctly went away. I'm excited to see what I can do with the rest of the spool!

This filament was really easy to print with. First print was successful although it wasn't a complex print. Very happy with with results and would recommend. I printed at 225 degrees with bed at 60 degrees.

Another great filament from HatchBox. This is a fairly firm flexible filament. Not at all like NinjaFlex, which is on the "soft" end of the flexible filaments and requires very slow printing speeds. This HatchBox filament prints at PLA temps and can be run at normal print speeds. It doesn't stick to bare, clean glass like NinjaFlex does (cold or hot) but it gives quality prints although quite a bit stiffer. This is because HatchBox put the flexibility rating up near the top of the scale (95 of 100) while NinjaFlex is down at around 20. When printed at the RX'd 190C extruder temp, the blue will give a very glossy-finish print, similar to their PLA in the same color. I have also recently ordered their red and green flexible filaments and expect the same results as this blue spool has given. The secret of the flexible filaments is to lower the infill for a more flexible printed object, and to increase the infill for a more firm print. Generally, something in the 12-20 range for more flex, 25-35 for more stiffness. Love this stuff. No noticeable odor when printing. Very pleased with this and have resigned my NinjaFlex to the shelf, although it does have some specialized uses.

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.

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