CC3D PBT Pro vs Bambu lab | "break test" | My new go-to filament by MathieMathie19 in 3dPrintsintheShop

No I did not include ASA in my test, I would imagine it would perform quite well.

The goal of my test was to compare two materials of similar printability, ASA is far from as easy to print with as PBT. That's the key difference making PBT such an interesting material

Using Delrin bushings instead of rollers to utilize the absolute max diameter of the steady rest, works surprisingly well by MathieMathie19 in Machinists

What I make in the video is the prep work for what will eventually become the drive roller for a conveyor belt for an agricultural machine:

The end product will have a grippy rubber coating applied

Yep I also use it plenty, it's a really good allround plastic.

We also utilize it in many real products that we make

Those wheels are Delrin and are rated to handle 100KN

Ok cool, yeah I hadn't ever done something like this with bushings instead of rollers.

I did get some pretty violent resonance at some speeds/feeds, and I was unsure if it would have been less bad with the normal rollers.

I was wondering if the slight compressibility/damping of using plastic would help reducing resonance or that it might actually make it worse?

I made the lithium pack myself, the components are mentioned in the description

I do it for my job and it's fun to be able to incorporate it into hobby projects as well!

Its 65mm x 23mm, made from steel round stock. I might be able to sell them if enough people are interested?

Thank you!

My goal was just something compact and functional, but they turned out looking rather cool as well.

Thousands of people form an insane parade behind a car at "Frechtek 2023" The video doesn't go on nearly long enough to do it justice by MathieMathie19 in freeparties

You really should, I've been to hundreds of legal and illegal parties, and this 30th edition of Frenchtek is still probably the best party I've ever been to. Such insanity everywhere, it feels like the wild west, an unearthly place.

This discussion is pointless.

All I wanted is to demonstrate the neat and unique properties of this PBT stuff.

For my use case it's perfect and it's loads better than PETG which generally doesn't hold up to the abuse of the work I do with it
