The printed body.

A humanoid you can print — the frame, the transmission, the actuators, the skin — is governed by one honest question: what can additive manufacturing actually do, joint by joint, and where does it hit a wall. The lab's answer is that nine of the ten subsystems inside an electric actuator already have a demonstrated additive route — structure, compliant transmission, flexure bearings, soft-magnetic iron, copper windings, bonded magnets, sensing — and the tenth, the drive die, is the one part that must be fabbed, not printed. So the robot is not a printed shell with bought muscles: every joint is one axial-flux actuator, AXF-1, re-sliced per joint from a single design — same poles, coils, magnets, and process, only the diameter changes. The cost of full printability is legible rather than hidden: bonded-magnet torque runs about half of sintered, so a lean 14-DoF walker carries roughly ten kilograms of actuators, and the sovereignty tax for printing the legs instead of buying them works out to about +38% of actuator mass in the design study. Every joint is priced in joules on the MathGround substrate, and every number traces to one cheap coupon — the remanence of a printed magnet.
