For my final project for Digital Fabrication for the Arts I used the 6-axis ABB IRB 140 robot in the dFAb lab.  The goal of the project was to create a tool head that focused light onto photosensitive paper allowing various images and patterns to be programmed into the robot.

tool head

The tool design consisted of several elements.  A 3D printed head was made to align an LED with a lens shield to control the amount of light that was focused to the paper.  The printed part also holds a 12in cardboard tube straight out from the end of the robot.  At the end of the tube in a lens that creates the focused beam.  The final focal length of the tool was 10in out from the lens.  After calculating this measurement I programed the robot to move in and out of focus on the paper so that an image of varying texture, contrast, and light intensity could be programmed.

CALLIGROBOT

This holder is designed possibly as a fruit basket or table ornament.  The joints are waffle notch joints.  I wanted to experiment between the CNC router and vacuum former in the dFAB lab.  I was impressed with the variety of forms that developed out of each pocket of the waffled structure as the plastic formed and cooled.

My 3D print works were explorations into the Rhino 4.0 command “FlowAlongSrf”.  This unique command takes three dimensional geometry and uses a reference surface to warp that same geometry into the shape of the target surface.  My first goal was to create complex interlocking chains to print in plastic.  After that I decided to push the limits of the plaster printer through the same process of warping geometries to other surfaces.

The creation is laser cut cardboard and acrylic.  The cardboard rotates inside the acrylic to reveal a storage cavity.  A stand was created as an improvement to the overall design.
