Just finished my first TPU print - Lemmy.world

Pretty impressed how well that one turned out. Used SUNLU TPU in yellow with 200/50 degrees Celsius at 20mm/s speed on my Voxelab Aquila (upgraded PEI bed and DirectDrive, also used Filament drybox). This filament to be exact: Angebot: SUNLU TPU Filament, 1KG Flexibles 95A TPU 3D Drucker Filament 1.75mm Maßgenauigkeit +/- 0.03 mm, Hohe Liquidität und Elastizität, 1KG（2.2Lbs) Spule, TPU Filament für FDM 3D Drucker,TPU Gelb https://amzn.eu/d/7H5TLjr [https://amzn.eu/d/7H5TLjr] [https://i.imgur.com/jJka7d9.jpg] [https://i.imgur.com/jHmmnf4.jpg] [https://i.imgur.com/ztlGg6g.jpg]

Really, really nice results!

I’ve been spending too much time in testing with fiberlogy 30D material on an upgraded ender 3v2 (direct drive, pei etc.etc.)

Gave up after three dozen test prints and sub-par results. Back to petg with great results.

Thanks! Fiberology 30D?! Never heard of that, but I assume that’s very soft? I am pretty sure my Extruder would just eat that :D What were your problems?

Yes, this is really soft material. Got the printer to produce some results, but a lot of blobs between gaps. Never achieved nice gaps between edges.

Tried this but my result is nearly as good.

TPU Flexi-Fish by Spiderpiggie

A flexible fish designed for TPU/flexible filament. The tail and fins bend well. This is also a good test print for several reasons: Its designed in a way where you wont need to worry about stringing, as there are no islands where the nozzle needs to lift or travel. There are also no severe overhangs so you dont need to worry about no sagging. It's fairly small, without being too small, so you wont be spending half a day printing at 30/40mms. (I printed at 50mm/s) It works well with 95a TPU. No clean up. Good for testing the properties of the final part. Or just for fun... My kids like it.

A friend of mine tried some softer material and managed to get better results printing really really slow. He also had blobs and gaps before that. Also he printed too hot. But I assume you already tried that. Maybe this community here can help? Have you considered making a post here asking for advice?

Holidays are coming, maybe I can find some time to give it another go. Last attempts was 20mm/sec, but maybe it needs even less speed.

If everything else fails, I’ll reach out here. Thanks.

I’ll keep my fingers crossed for you :)
