But there is no way that a bearing on a RepRap reaches such high temperatures, so I don't have to worry about its toxicity. Even if locally, a tiny little fraction gets heated due to friction, the amount of harmful substances produced would be far below safety thresholds.Quote
PTFE is TOXIC when heated too high. Fluoro anything is usually more stable by more harmful to manufacture/burn.
Where did you get that from? Never heard of this before.Quote
Delrin is OK but explosive if heated in the presence of brass (read: fireworks).
That's one of the reasons why I would like to continue using this material (if only one could print it!).Quote
UHMW is cheaper, hands down.
I wouldn't. PTFE creeps more than UHMW-PE, is softer and has terrible wear characteristics.Quote
I would use PTFE where machining is or hardness is needed.
