> I'm always surprised that 3D printing isn't making faster progress. I don't own a 3D printer, but I wonder why pellet extruders are not a standard for feeding these FDM machines. This apparent lack of interest has an effect on the price of the excessively overpriced and seemingly amateurish pellet extruders that seem to exist at the moment (of which there seem to be only two or three models?). We are talking about a significant price difference in the cost of consumables in pellet form, humidity of the material and mixing control, and the ability to reuse material from failed prints or everyday items, among the first things that cross my mind. it's been like this for nearly a decade as you said, and the common extruder usually doesn't even include an acceleration sensor.
