Make the body — and make it survive.
A robot's body takes loads a display model never does: torque at the joints, vibration in flight, impact on landing. Printing for Physical AI is its own craft. This section is the practical guide — materials, tolerances, joints, and mounts — anchored to the Bambu Lab workflow so you can go from plate to bench with parts that hold.
What a robot body demands of a print.
What to print robots in
PLA to prototype, PETG and ABS/ASA for parts that take load and heat, TPU for compliant feet and grippers — and when to reach for carbon-fiber blends.
Fits that actually fit
Clearances for shafts, bearings, and press-fits so joints move freely without slop — the difference between a demo and a robot.
Print-in-place motion
Living hinges, captive pins, and print-in-place assemblies that come off the plate already moving, with no hardware.
Holding the hardware
Actuator brackets, board trays, and sensor mounts that survive vibration and the loads a moving machine puts on them.
Plate to bench
The MakerWorld-to-build path: slicing profiles, multi-color and multi-material, and organizing a multi-part robot print.
Model it to make it
Orienting for strength, avoiding supports where it counts, and splitting big bodies into printable, boltable sections.
Printable bodies, growing.
Bodies for the builds on this site — brain-agnostic, printer-agnostic, Bambu-anchored — with print settings that have actually been run.
◱ Modeling Files land here as each build is verified on a real printer. Kits follow once the library is rich enough to box.
