Research and Development in Self-Replicating Open-Source 3D Printing
We have been experimenting with 3D printed Ravigneaux epicyclic gears to get a high-reduction-ratio gearbox in a compact space for making robots. They work if you drive them with a high-torque from an already geared-down motor, but they suffer from
A while ago Naomi Wu 机械妖姬 very kindly sent us one of Creality‘s infinite-Z belt printers. Lots of people have printed long I beams on this type of machine, but we thought that we’d write a Python FreeCAD program to
It’s often the case that you need to 3D-print objects that must slot together, like the grey and red parts slotting into the white central hub in the picture above. (It’s a design for a 3D-printed BLDC motor that we’re
Most recycling streams are not set up to process PLA, despite the fact that PLA is probably the most widely-used 3D printed material and is easy to recycle in a number of ways. This needs to change, and the 3D
