So much great data! Thank you for doing all these tests.

[@stefanguiton]

Excellent videos as always!

[@spongecounter]

Thanks, Igor. I like these filament test videos.

[@MyTechFun]

More comming soon, but some of them after my vacation..

[@brezovprut4431]

As always great comparison !
It would be cool to compare eTPU Antibacteria with ColorFabb VarioShore PROSTHETIC (antibacterial version).

[@MyTechFun]

First there will be testing all 4 Extrudr TPU filaments, one of them is with carbon fibers... I am curious already..

[@kwinzman]

@@MyTechFun I love the Extruder ASA filaments, for their UV resistance and flame resistance. They are UL94 HB.
But I can not find any filament that is ASA and has higher certification. Like for example UL 94 V-0.
Only ABS filament, which I don't want to use because ASA is just better than ABS.
Any idea why there is no ASA filament with higher flame retardant certification? Maybe you can ask them :D

[@kwinzman]

Amazing data as always!
Any information from the filament manufacturer how that antibacterial effect is achieved and how durable the antibacterial substance is?
Is this an inherent property of their TPU or is this an additive?
Will the antibacterial last 1 month? 1 year? 5 years?

[@MyTechFun]

If the effect is by metallic ions, then they will be there a years later too. I asked them before the review, what is the effect material, but they told me it is a secret (usually they are silver ions, sometimes copper ions)

[@samuellobo6242]

Is it food grade

[@iamdmc]

a bit useless
if you're more interested in keeping it "antimicrobial" make every surface as smooth as possible. Microbes love grooves in 3D prints

[@MyTechFun]

Yes, but sometimes you cannot access to all (inner) surfaces for smoothing (with Epoxy for example)
