Materials list, settings and machine specs

Machine - laser cutter specs

To create our lamps, we only used a laser cutter (machine/process available in many Fab Labs)

  • Fab Lab Wgtn's laser cutter is a ILS12.150D Universal
  • powered with a 105W laser unit
  • with a bed-size of 1219.2x609.7mmm

Material tests

So far, we made great lampshades out of

  • 0.6mm polypropylene (the white model) or 0.35mm colored craft paper (the dark blue model)

  • and 3mm acrylic (for the light socket fitting)

--

We also tested the following materials for the lamp without much success

  • 0.45mm craft paper was too thick, it made the creasing too difficult

  • 0.15mm & 0.20mm craft paper was too thin, the final structure couldn’t hold itself

List of materials for one lamp

To create one lamp and light it up, we recommend getting

  • a 500x500mm piece of 0.6mm polypropylene or 0.35mm colored craft paper

  • a 85x80mm piece of 3mm acrylic

  • a light bulb (between 1,800K and 3,000K)

  • a light socket not too large (we used one with 33mm diameter & found a matching light bulb)

  • a power lead (prior to buying, think of where you’ll put it & the length you need)

Material settings for the laser cutter

All vectors, print in order. The settings on the picture are for the 0.6mm polypropylene.

For all materials but the acrylic, you will see that the PPI for colour blue is down to 20 pulses per inch.

This makes a dotted line instead of a continuous line, allowing light to escape as well as making it easier to crease the card in the direction you want it to, and create a sweet result for your customised illustrations on the petals!
