There are no electronics embedded in the sleeving or the finger. Tubing runs from each printed port to a barometer sensor, and a Raspberry Pi Pico 2W microcontroller reads the sensors and drives the arm's servos, with control handled from a web browser over a local network. The sensing element is the geometry itself. That distinction matters on a factory floor. When the part is the sensor, a worn contact pad is not a rework order. It is the next print job.

ooling introduces draft angles that alter cross-sectional geometry in the sealing zone. Overmolding requires secondary bonding operations that add variance. Multi-material requirements get resolved by splitting a single component into an assembly, which introduces tolerance stacking at every interface. The design team knows what the part needs to do. The manufacturing process determines what the part actually does.

What We Tested We evaluated twelve standard lattice configurations across four structural families: Gyroid, Diamond, Fluorite, Octet, and BCC. Each was printed in TEPU 30A and TEPU 50A using Inkbit’s Vision-Controlled Jetting platform.
