91.548 Meeting 3: Laser Cutting
This week we are using our new Trotec laser cutter.
The basic procedure is illustrated below. We use CorelDraw to draw a vector or raster image, print it to the Trotec driver, and then use the Trotec driver to talk to the laser:
It's also possible to use the HPGL file format as a go-between so that you can write code that describes objects to be cut:
Play with the laser. Make something cool.
For materials, right now we have cardboard, wood, and acrylic plastic sheeting. The foam core doesn't work too well 'cause the foam just melts.
You can also engrave on found objects. Beware that PVC plastic should not be cut: it emits chloride gas, which is toxic. Cardboard is a good prototyping material anyhow.
Important safety notes:
