Experimenting with the laser-cutter

starting from this picture

First try-out on 6mm plywood.
The wood was bent an the laser got stuck -> interesting glitch

Create a texture on 3 mm acrylic

Over-saturated pattern

experimenting with different tracing settings

first 4 -> failed because I forgot to convert the file to RGB

->

It started doing a second layer stronger, but I had to stop it mid-way

Using the laser-cutter for the process of slashing textiles

Before putting it in the washing machine

After putting it in the washing machine

Experimenting with different powers and speeds

Trying to engrave on different, thinner acrylic

Initially: seeing if the heat bends it
...
It didn't

Interfering with the file

Odd Matter

Engraving a Marble pattern on Foamboard

Interesting shiny effect

Revealing the layer underneath

Different type of file -> less interesting effect

Engraving on hypertrans laser film matte sheets

Looks almost like printing

Can I try to make them look even closer to printed images?

Interfeering In-between

Coloring the paper before engraving

Changing power/speed of the machine while it is engraving

Taking it further

Trying to cut it

Going bigger (A3 Sheet)

Creating an image that is not defined within a clear rectangle

Trying to print a bigger, fuller image in the laser cutter from the interaction station.

It did not turn out as good as the ones in the digi lab -> i had to adjust the power a few times and i still didn't get the same effect and the paper got creased

I tried experimenting with different colors, in this case using the copic markers.

I think the black, red and dark blue give a nice effect, but also the subtlety of the yellow is interesting and can be explored further.

Some failed attempts.

The paper moved and the machine kept engraving.
