- Enclosure: not necessary.
- Build Surface: Kapton tape (PEI), blue painter’s tape.
Is TPU filament hard to print?
TPU is more difficult to print compared to other filament materials, mainly due to its flexibility.
How do I make my TPU print smooth?
If the filament becomes too saturated with moisture in an overly humid environment such as near a coastline, then there might be print quality issues such as air pockets. Fortunately, this can be fixed by drying TPU in a food dehydrator or a low temperature oven.
Can TPU be printed with PLA?
Will PLA stick to TPU? PLA will bond with TPU without too many issues, but the bond won’t be too strong, which is why PLA is often used as a support material for TPU prints since it’s quite easy to remove.
Why did my TPU print fail?
An unleveled bed is the first and most common cause of TPU printing issues. Warping is the most common outcome of an unleveled print surface. In general, every 3D printer uses a different leveling mechanism. Some have four or more knobs under their print surface, which can change one corner’s height.
Does TPU need heated bed?
TPU does not require a heated build space. You also don’t need a closed build space. If you print TPU at low temperatures, warping is also less likely to occur due to the not quite high shrinkage of the material when it cools down.
How do I stop TPU from clogging?
TPU is a very soft material, and if it moves in and out of the nozzle repeatedly it can get stuck in the hotend. Lower the retraction distance to 2mm and decrease the retraction speed to 20mm/s to prevent clogging and underextrusion, the less retractions the better.
Can you print TPU with supports?
Just use your TPU extruder for both the model and the supports. You may have to tweak the support settings a bit. I never tried breakaway as support material for TPU, since for my parts TPU supports have been adequate so far.
How do I print with flexible filaments?
Flexible filaments typically print best using a slow and consistent feed rate. Because the material is elastic, it can be very difficult to control sudden changes in the print speed. Higher print speeds can cause the filament to compress and will most likely result in a jam. Slow and steady is the best approach.
What temperature is TPU?
Flexible filaments, one of which is TPU, are fun and useful materials to work with, but they can be very difficult to use. TPU prints at similar temperatures to PLA, working best at around 210 to 230 °C with a bed between 30 and 60 °C.
Does resin stick to TPU?
In our review of BigRep’s flexible TPU filament, we discovered that the material works remarkably well for making epoxy resin molds and we promised a tutorial on how to to make them.
Is TPU hygroscopic after printing?
TPU filament is hygroscopic, which means it absorbs moisture from the surrounding air – it is therefore recommended to store the material in a drybox; a (mostly) air tight container with silica gel in to absorb moisture from the air.

Will TPU stick to nylon?
Now, so far Nylons and Flexibles all play by somewhat similar rules, but when it comes to bed adhesion, they’re quite different: Nylons are hard to stick down, while TPUs will stick and often permanently bond to a ton of surfaces.
Can you mix PLA with ABS?
This is not a good idea. Both filaments have different melting points, that of ABS being much higher than that of PLA. To melt the ABS you have to heat the plastic to the point where the PLA starts to degrade. While I agree it’s not a good idea, I don’t think it’s completely improbable.
Will ABS bond to PLA?
Plumbers ABS cement is also a good option for gluing ABS, PLA, and HIPS. It’s a solvent-based glue that reacts with plastic in the same way as acetone. You will get a very strong bond with it, but the bond will be visible since these types of cement are colored (usually yellow or red).
How do I change the color of my PrusaSlicer?
You can easily add color changes from the Preview screen – drag the layer slider up or down and then click on the orange plus icon. Check this video to see it in action. Unlike this web app, PrusaSlicer displays a realtime preview of each color change and even a print time estimate until each color change.
