I made a prototype assembly for an overseas customer and they’ve been testing it. They’ve asked me what material I used for one of the parts and it turns out to be Hello Matte Red PLA. This part is supposed to be in steel on final production units but my printed one is holding up in durability testing so they wanted to produce the preproduction units with printed parts like mine (I didn’t do steel either because it’ll take special tooling to make) but their printed ones from a local jobber are breaking. I thought they might break myself so I printed a few extras (I have here) so that I’d have them for my testing in case one broke and none had broken, so examining the part I find it’s very (unusual for PLA) flexible I’m printing one now in regular non-matte pla but I have a feeling I’ll be able to break it because similar parts are like it are regular, brittle, breakable PLA.
My question. is there something about matte PLA that makes it different? I used the whole roll in their job so if it’s a unicorn I might not be able to reproduce it. They have the jobber coming into the factory now. he’ll be there in a couple of hours so it would be good if I could tell them something about the composition of this PLA so they can reproduce these parts there with locally available materials.
