Shadow Projections by Sam Berg

| 2 Comments

Samantha Berg, a student here at the department, used the laser cutter to create a wonderful shadow projected image by etching clear acrylic and shining a light on the image (as seen in the photo below).

The image below shows what the acrylic looks like after it is etched (the clear acrylic was photographed behind a black background to show up in the photo better).

When etching acrylic for shadow projecting purposes it is important to make sure your original image has high contrast with relatively few midtones from there the image should be halftoned with relatively few dots or circles per inch; this creates more clarity in the projected image because when the dots are too tight they etch more surface blocking light from passing through the acrylic.

Knife Template by Paul Linden

| No Comments

Paul Linden a member of the Technical Staff here at the department used the laser cutter to create templates that were used for tracing onto metal (for the blade) and wood (for the handle). After he traced the template he cut the metal and wood out using traditional methods. Paul also used the laser cutter to design a template for the silhouette of the knife handle. Once all the pieces were cut he assembled, sanded and sharpened the final product as seen in the photo below (the final knife show was made from a similar but differently dimensioned pattern).
