First Build makes an impression

MATLAB model to CNC-carved Modulan mold

FirstBuild is helping make a molded plastic diffuser for the Trilife cellular computing project.

The MATLAB file (rainbow colored inset) got CNC milled into a Modulan tool for vacuum forming thanks to Jeremy Turner and Randy Reeves at First Build.
We are looking at PETG for the plastic that will be formed over this mold, because PETG is paintable and can also be laser cut. These diffusers will create the triangular light reflectors that we currently get from folding paper. The paper works great, except it crumples up a lot in transit.

The MATLAB code to create the diffuser surface is… Continue reading
