gcode files on an SD card, and into your printer Run them through a “Slicing” program, this (a) turns the solid 3D model into a structure of layers and ‘infill’, then (b) outputs the “GCode” this is commands that tell the printer what to do, layer by layer,.The SFX-100 actuators require around 200 hours of printing with 20 individual parts that need printing. Once you get past the initial setup it’s usually only a couple of minutes setup work and your print is underway. It isn’t as daunting as you think, and isn’t as expensive as you’d think.
Without 3D printing this would likely mean CNC machined aluminium blocks. 3D printing makes the actuators possible – the bearings, and motor all need to be at certain positions and held solidly in alignment.
