A couple printed widgets

[A2022]

I’ve been experimenting with PPS CF-10, a new material for me. When dropped onto a surface, it sounds like metal but is actually lightweight plastic. I printed a spark plug baffle wire seal with it. Its heat resistance is claimed to be better than the Slick version made from PEI. After testing and breaking a few pieces, I found it’s not as tough as nylon or PEI, but for this application, toughness isn’t critical. The material max operating temperature rating is greater than 400°F, though I would conservatively rate this printed part to about 350°F. I use the high-temp nylon version in my aircraft, mounted directly over the cylinders, and been happy with them at their 300°F rating. This PPS material could open the door to even higher temperature applications. Fun stuff! Now back to work on my bicycle kickstand extension.

see and hear the part drop video.... sounds like metal
