Hi
TPU is very versatile and prints very well on the X1 (especially TPU HF from Bambu).
But, there is one problem: I have not yet found the ideal plate for printing.
-glue stick → is a NoGo for me. I will not even try to mess around.
-Engineering plate → not enough adhesion, even when heated to 60°C
-Cool Plate / Hot plate → way too much adhesion, prints with large area can hardly be removed. Using ethanol helps, but there is always a risk to damage the plate.
How do you print TPU?
I use whatever works, which has been engineering, smooth and textured PEI plates. All with glue, because using it is much easier than messing around trying to remove a print without glue. That is probably why Bambu recommends glue.
Flat out refusing to do what is necessary reminds me of this door sticker:
Give FR10 a chance 
Also available as G10 or matching your printer as TK99.
A resin/fibre board that is heat cured, same material is used for circuit boards.
You will need to use clamps but it works rather well with most tricky filaments that struggle on PEI or need adhesives/release agents - just print on the bare plate.
Of course you have to make sure the plate is properly cleaned!
Ethanol or IPA first, than a sponge and soapy water, rinse under running water and dry with a lint free cloth, preferably microfibre.
You crank your bed temp as high as you like, FR10 / G10 / TK99 is good for around 300 degrees Celsius…
I use the textured build-plate and have NEVER used glue.
I use both standard TPU and high-flow TPU and have no problems with either or removing from the build-plate.
I’ve been using the supplied PEI with TPU without any issues. Sure it sticks well, but no problem getting it off the plate. I’ve had issues printing, like spaghetti etc, but solved them all by keeping the door open. Seemed to be a heat issue for me
Hi sir
I am a beginner… getting a P1S AMD 2 pro printer today … want to print TPU filaments … should I buy textured plate … or cool plate ? which one is good
should I use glue when printing TPU… heard it is not easy to remove after printed on the plate
thank you
Assuming that you are referring to the Cool Plate SuperTack and not the now unavailable previous cool plate…
- Do NOT print with TPU filament, as it will damage the build plate.
From the information on the build plate sales page.
I use the textured plate.
Review this guide for a comprehensive comparison of all the compatibilities across filament, printer, build plates, glue, and more.
I use textured, slathered with glue quite well. Glue is actually to impair the adhesion. You do need to wipe the model clean though.
Remember that glue isn’t a universal requirement, it is dependant on many factors including: ambient temperature, humidity and more.
I have never required glue for any material on any build plate.
Experimentation is the key.
Find what works and do that.
Different TPUs seem to like different surfaces. From my limited experience I’ve found that actually doing the opposite of what’s common knowledge sometimes works out.
For example: Using textured PEI and having the bed at 10 degrees, I’ve found some TPE/TPU sticks better with a lower temp bed. When I get past 30+ degrees the material begins to lift at the edges and not stick properly. I had read that higher temp bed usually equals more stick, I found the opposite to be true for my setup.
Also, increasing the initial layer height to squish some material on to the bed can help with adhesion. I used to use glue stick but the finish wasn’t nice so I spent a long time trying to crack it, and for me with my setup and filaments it’s working great now so it’s possible.
If you have no luck with one filament, find another with similar properties and maybe that one will behave.
