Typically the glass transition for ABS is 105C, not 150C. This seems to me to be well within common temperatures of surface stove use and well above common temperatures inside an oven.
It can probably handle 105C just fine but by 120C the handles will probably be as soft as clay. Maybe this is good enough for boiling things - I’m not sure.
Yeah sorry about that, typo! It’s definitely 105C. I hope they withstand stove use, in testing right now time will tell. I probably should have used sintered nylon but I wanted to try out the vapor smoothing.
Yeah, it works pretty well and doesn’t take too much work. There are a bunch of youtube videos about vapor smoothing including quite a few different techniques.
How about using your new handle models to create plaster or fiberglass molds or if you could reverse engineer the drawing to print out a mold rather than the handle itself, now that you know they fit, and look good and functional. Then cast the handles in resin i.e. fiberglass resin or some other derivative. As resin is chemoset rather than thermoset those handles would be able to handle the heat much better.
Sounds like a bit too much work for just a handle for a pot. Before going through all the trouble of making a mold and all of that I would just buy a new pot. The next step I would take, if the heat ends up being too much would be to reprint them in Nylon and see if the results are better.
