I milled a Mesostructure in Trinia on a PMMA strat worked just fine.
With special cutters? Strategy for implant bridges...

you really don't need much special for Trinia or Trilor, just good chip evactuation.
theres a limit to how fast you want to be spinning the tool too, because while small chips are best for high speed machining, theres a point at which that stops being useful and instead becomes problematic.
you can spin the tool so fast that it just melts the material you are cutting, and that can be detrimental in 3 ways. 1. the thing you want to make you end up with melty spots if you finish milling it. 2. the melted material tends to adhere to tools with coatings, making you have no more sharp edge but a crusted blunt edge. 3 you might be spinning so fast that your machine can't produce torque at that rpm, rendering your tool into a bomb.
for glass polymers like trinia and trilor, no big deal. for peek, pekk, pmma, and polycarbonate, big big deal. 1 flute cutters work best for these materials because it allows you as much capacity as possible for chip removal. this means you can run it faster. but faster within reason, remember you now have a tool with one edge, which is not well balanced. keep within the torque curve.
