Hi, does anyone have a profile for TPU95-HF that I can use as a starting point for my printer (modified Prusa i3 MK3S+)?

maybe the generic flex profile works? actually wait no that didnt work for me. I have a tpu90 profile that works for a stock prusa... its kinda sketchy with 4.5mm retracts at 15mm/s but it works to some degree

Take your pla profile and increase the retraction to keep stringing. It will run 🙂

I hardly ever use PLA. Regardless PETG would likely be closer.

Closer? What are you printing petg at?

I personally print HF-TPU at 100mm/sec no problem. And it prints at PLA temps more than PETG temps maybe way too high.
Regular TPU generally doesn’t do well with cooling, HF-TPU does much better with light to full cooling. Which helps speed. The main attraction to the HF-TPU is the drastic increase in printablity which is why it can easily demand the higher price and limited color pallet.

I wouldn’t worry so much, do a basic PLA profile and bump up retraction distance slightly, 40mm/sec retract, 25mm/detract, and try it on a small piece like a Cali Dragon, you will likely be very surprised how well it does.

The melt index information is very helpful here from Polymaker, which is available on their website's material comparison chart.

Rather than targeting a speed in mm/s, you care about volumetric flow rate. This will inherintly control the printer speeds in mm/s. I would limit your volumetric flow rate to ~1/2 of the melt index or 4.6mm3/s to start and work up from there.

For PolyFlex TPU90, Fiberology 40D, 30D, we reduce or eliminate retractions. 95A is much stiffer so this will be different.

I have a working profile now. But also a blob. Anyone know what chemicals dissolve TPU?

TetraHydroFuron THF, it is nasty stuff use the UP MOST CAUTION⚠️ double read directions. But it will get the job done.

cant buy over the counter anyways. only seek if you have atleast a basic understanding IF you even can buy it!

You can buy it on Amazon in most of the USA

#

I have ordered it a few times personally.

Granted your not wrong it isn’t generally available outside industrial setting and is dangerous but it works really well very similar to gloop.

I replaced the LCD brackets on my Prusa with a pair printed in Polymaker TPU95-HF and it significantly reduced some of the more obnoxious vibration noises.

This stuff prints beautifully.

never thought of doing that
