Protopiper: Physically Sketching Room-Sized Objects at Actual Scale

Protopiper is a computer aided, hand-held fabrication device that allows users to sketch room-sized objects at actual scale. The key idea behind protopiper is that it forms adhesive tape into tubes as its main building material, rather than extruded plastic or photopolymer lines. Since the resulting tubes are hollow they offer excellent strength-to-weight ratio, thus scale well to large structures. 

 

Make the device on Instructables!

The device itself is an assembly line: the tape is drawn from the roll, shaped into a tube, sealed together, and cut off with a wing connector.

Protopiper’s tubes also afford creating simple mechanisms. By creasing them, for example, users form hinges. Hinges allow for moving mechanisms, like the opening-closing umbrella.

Protopiper works equally well for freeform expression, such as the T-Rex sculpture.
