About the Class
In his global class, Neill expanded on the content of the local class, which introduced us to the Trotec 400 laser cutter and the Roland CAMM vinyl cutter. This included preparation of files for the two machines, pre-print routines and mechanical aspects, such as safety measures and material considerations.
Building a lighting edge sign
For my personal homework project, I decided to build a glowing edge light sign. It features a box, housing a LED strip and power supply, together with an engraved sheet of acrylic. By lighting the acrylic sheet from below, the engraved motive on the acrylic plate appears to be glowing. Using the Trotec 400 laser cutter, I manufactured the press-fit parametric box from 2,5mm MDF plates. As the time slots were heavily compressed when using the laser cutter, the acrylic sign was not manufactured on that day. Instead, I cut the acrylic sign in the subsequent week. For time reasons, I omitted the Grasshopper-generated background design on the sign.

assignment
group assignment:
characterize your lasercutter's focus, power, speed, rate,
kerf, joint clearance and types
individual assignment:
cut something on the vinylcutter
design, lasercut, and document a parametric construction kit,
accounting for the lasercutter kerf,
which can be assembled in multiple ways,
and for extra credit include elements that aren't flat
