    I picked up .5kg of poly to try out as the picture shows it has a very high working temperature. I ended up at 245c to get it to flow and stick well. I reprinted the parts for my pot mount and I am impressed. The original parts were printed in ABS. The ABS printed good with resolution better than I could obtain with PLA. The poly printed with a lot more detail and much less curl at the edges than the ABS. This material was almost double the cost of ABS, but the parts are more detailed. The polycarbonite finished part is almost as hard as PLA but not as brittle. When the printer finishes a job the extruder lifts leaving a little stringy piece of plastic, this can be seen in the second photo. Normally I just knock it off with my fingernail. With the poly i couldn't i had to cut it off, it seems way more durable than the other two types of plastic I have been using. So in the end I believe poly though more expensive is easier to work with and turns out a better and more durable part.

    this bracket was printed at .2mm layer height

    these were printed at .1mm layer height abs left poly on right

    The ABS is prone to curling/shrinking as it cools. the poly did not do this. ABS left Poly on right

    hey @bruce stephen thanks for the heads up with the new material , few more bits to print off just pushing the times and parts size a bigger and times little longer with each model , will have to try this material at some stage just to compare how the machine holds up . Cheers
