I wonder if that's possible, it means your print need to be very sturdy even when not finished.
Also need to have an excellent bed adhesion.
Also milling plastic is complicated.
- buildbot 2y agoAnd your frame must be much stiffer, as now your tool is being used to apply force vs just lay down plastic.
- yetihehe 2y agoHmm, milling is complicated, milling hot plastic is almost impossible, but maybe a head with heated rod to gently iron the plastic? Like ironing with printhead, but specifically shaped to also iron laterally?
- justinclift 2y ago> milling hot plastic is almost impossible Automatic pause time of (say) 5 mins before starting the mill process? Or even some kind of thermal measurement (laser?) instead of using a fixed time. Perhaps even fan forced cooling? The milling tool would need some kind of vacuum near it anyway for debris clearance.
- yetihehe 2y agoIf it was done after the print, you could use water (mist) cooling, would probably help a lot with preventing plastic sticking to your endmill. If it's done mid print, you would probably like to do it for each layer, so no long cool times and it should be hot anyway for next layer. Using printhead for this (like for ironing top layers) would create a lot of blobs from dripping plastic.
- nom 2y agoI can imagine a tool head for ironing. Small metal sphere on a rod, like those touch probes, attached to a heating block. Every couple layers you could iron all the walls, fix those layer lines and overhangs you get on shallow angles. Tool changers are awesome, I can't wait!
