Experimenting with melting and bending perspex

 

 

Carrying on with my material experiments, today I am melting and bending my perspex etchings to give them a sculptural form.

To shape the melted perspex I have bent steel sheets into a range of different curved formations. These metal shapes will act as a template for the perspex to mould to when it is hot.

I am pleased with the results of these experiments and am hopping to create similar work on a larger scale for my degree show.

Perspex etchings and prints

 

 

 

Today I printed from my perspex etchings and achieved some nice results!

To do this yourself you will need access to a laser cutter and a printing press.

To achieve the depth of etch on my perspex,

Here are the settings I used:

  • First convert your images to black and white and up the contrast on photoshop.
  • On the laser cutter, set your images to the size you want (mine are 13.5 x 15.5 cm).
  • Posturize your images.
  • Use the rectangle tool to draw around your images.
  • Change this rectangle to hairline and colour red (this indicates the laser to cut all the way through the perspex)
  • Go to printing preferences
  • Advanced – set the etch cut to 3mm
  • General – resolution – 300 DPI
  • General – engrave direction – bottom up
  • General – image dithering – Floyd Steinberg
  • Colour mapping – black – speed 60, power 100

 

Feel free to play around with these settings further to achieve different results.

 

Happy experimenting!

 

 

Experimenting with the laser cutter

Today I have been etching my collection of photographed textural matter onto perspex with the laser cutter.

At a later stage I would like to experiment with printing from these perspex etchings.
