I have been wondering why polypropylene isn't much easier to source as a 3D printing material. Given its incredible flexibility it should be much more widely used than it is. The price would also likely fall with greater demand. Your dedication and attention to detail are admirable.

Thanks for the video. i haven't been able to find much info on PP. You always supply so much information, thank you.

Every one: wow this is so interesting and educational
Me: hehe pp

I'm so happy that you tested this material. PP is something I have been wanting to print with but have always been intimidated by the potential for warping. It is quite interesting how well the interlayer adhesion performed. Cheers!

[joemulkerins]

Because of the mentioned properties ( hydrophilic, heat/chemical resistance etc) I think PP would easily surpass most flexible filaments with some development. Excellent engineering video as always! Thanks.

[nerys]

those layer bonds are amazing. as for tape residue. thats easy. painters tape THEN PP tape. :-)

what about high temp deformation? it gets wobbly when hot but does it return to printed shape or "retain" the new shape if you bend it when it cools?

ie how well will parts survive in a hot car? might make for good nose cones!

I’m a big lover of PolyPropylene I think is such an amazing material and layers adhesion is great!

Great video! PP is an underrated material for 3D printing indeed...
Thanks for mentioning my channel. Cheers, Robin

I've used some Forefront F43 TOUGH PP (black) myself and was super impressed by it's layer adhesion and surface finish, when printed in 0.1mm layer height it's almost as if it's injection moulded. The nice thing about the F43 is that it can be printed at 200C so there's less warping. Also the layer adhesion is really annoying when it comes to supports on large objects/curved surfaces, the supports are borderline impossible to remove.

I used it to create some velocity stacks for inside of a motorcycles airbox as it's properties were ideal for the application (They were designed to snap fit into the airbox + good chemical/temperature resistance).

You are the boss Stefan! so much rich information, perfectly sort, wow, you are doing a really professional work ! keep doing this amazing job and providing this invaluable information!

[skydance]

Einfach danke für deine wissenschaftliche Vorgehensweise!!!

[David-uknv]

Finally some info on PP. Thank you!
As a suggestion for the next material to review: POM

[GabbyMoore]

All you videos are fantastic. Thank you for all your hard work. I have a project where PP might be good and your video was just the information I needed.

[devluz]

I was surprised you got this thing waterproof. Would be great if you could make a video about making things waterproof in general. Great video btw!

[mleitner]

Man I love this channel for 3D printer is amazing.

[sirkooshiar]

very comprehensive and honest. this video answered all of my questions about pp filament. thank you.

[CDPropShop]

That's an awesome material! Can't wait until it's more widely available!

[Djchrisman]

Love the information presented here! Also, that finger poke definitely made me lol :)

[minitos]

Amazing filament, I wish more brands were available..

[NilesBlackX]

I gotta say, Gearbest's sponsorships are totally up my alley.
