The 3rd prototype was build from matte carbon tubes and printed parts made from FormFutura CarbonFil filament. The frame parts are from the initial design iteration. The later revisions of the triangles are glued and use less screws and threaded brass inserts. Still this all carbon printer looks very appealing and produces beautiful prints.
The machine is equipped with an E3D V6 hotend, a Bondtech QR extruder (1.75 mm), a 230V/450W heated bed with Filaprint surface, an Panucatt Azteeg X5 mini V3 controller, TMC2208 stepper drivers, a Raspberry Pi 3 running Octoprint and a HD camera for time lapse recordings.
