Hey all,
I came across an unusual filament recently - "PBT Pro" by CC3D, and shared that it seemed to be remarkably tough. Naturally, I decided to build a combat robot using it, to see just how tough it really was.
This is the first test of that bot!
"Death Ray" has a large undercutting blade, and in testing I put it up against old frames printed in PLA+, 64D TPU and the new PBT Pro filaments. The results were... unexpected. TPU remains the best option for durable combat robot frames, but I'll keep testing unusual filaments as they come past my radar.
Full video will be released here sometimes soon, then on the YouTube channel at a later date. Watch this space :)

I've just received some Durapro PC/PBT from Extrudr.
280-290C, hotbed @ 110C, 1.2g/cm3 - its certainly tough (much tougher than PETG in the same part), and you need serious equipment to handle the temperatures (Prusa XL handles it fine). We'll need someone (CNC Kitchen?) to do some notch testing!

Nice! The PC would definitely bring the toughness up but yeah, that heat bed requirement is pretty high! I've got a similar roll on its way for further testing. Stephan is definitely the guy for the job, I'll send him a message.
