Abstract

The paper present novel digital fabrication process that assembles building blocks
to create a three-dimensional object. The system consists of an assembly robot and a
fabrication head installed at its tip. The head, consists of a vacuum gripper, an adhesive
extruder, and a camera, and is thus capable of gripping and releasing a building block,
applying an adhesive, and determination of the position of things in the process. The
calibration process and the design and build workflow for this technique are mentioned in
the paper. The process is a discrete fixtureless manufacturing process that gives faster speed,
compared to both additive and subtractive manufacturing processes. Tiny mosaic pieces are
used as building blocks and fabrication of a curved bridge model is used to demonstrate
how this process works and its performance.
