Dreaded blinking light on new Visionline Big Boy

Lots of high temp materials how much heat would it need to resist? Some of those materials are hard to print. I am sure those impellers are injected molded ABS which is pretty high temp.

Well, it would have to be higher temperature than what they're using now.

This looks like a great candidate if someone could make me a cad file of the impeller I could make some and send them for testing.

Polycarbonate (PC)

This material has a crystalline melting point of about 230°C – 260°C and a glass transition temperature of 147°C. Polycarbonate is a tough and amorphous material with high impact strength, stability and good electrical properties. It has a wider temperature range of usage with a heat deflection temperature of 140°C. It is widely used for the production of safety helmets, lenses for car headlamps and bulletproof glasses.

• Technology: Fused Deposition Modeling (FDM)
• Key Features: Translucence, pliability
• Common applications: Plastic lenses in eyewear, protective gear, automotive components

Yep, the CAD file is usually the sticking point for these projects.

Do you know what is causing the high temperature damage to the impeller?

I'm guessing the temperature the impeller is seeing is in excess of 550 degrees F.

ABS melts at 390 degree's so at least that hot
