I have done some printing in POM (acetal) which has very much the same issues as olefins. It is very slippery, and very high shrink rate which means all it want to do is curl and peel off. Incredibly strong when it works though, I have made several complex plastic spring prototypes with it that would be very difficult to make any other way.

My best results were with a 120degC bed, painted with ABS slurry, and the key bit is to repaint over the first layer of POM with slurry again, which effectively glues it down. I then close the enclosure, which sits at about 60degC, any less and the high shrinkage will give you delamination.

Hope this helps. Good luck.

Andrew

Am I crazy or do you keep saying polypropylene?

What is the other material you're using?

AFAIK there is PP filament but it needs something like 290°C IIRC. I doubt that it will ever work with a standard UM2 hotend.

Polyethylene is the other common olefin, I guessed he meant that.
