Process of laser cutting/ engraving
By Adrian Duyn
Having received the various black and white contrast scans, I digitally image trace the outlined profiles, making sure to include even the smallest of details. I then transfer the new files to the editing software on the computer, which is attached to the C02 laser engraver/ cutter machine, to make final adjustments and confirm the sizes required.
A CO2 engraver/ cutter uses a water cooled – gas filled tube and various mirrors. The mirrors focus and guide the high power laser beam onto one specific spot. From there the laser beam bounced around in different directions across the machine by angled mirrors, focusing down on the machine bed.
For Corina Duyn’s shadow images I selected a 3mm wooden sheet material for the cutting. It would be structurally sound once cut into the required shapes. Placing the material flat onto the engraver machine bed, I then focused the distance of the laser beam to achieve a pin point accurate cut.
The machine has two main functions – engraving and cutting. Engraving is the process of taking off a minimum top layer of the materials, with the machine making numerous passes to achieve this. Cutting is a constant beam of laser following shapes or lines. Many different effects can be reached by altering the two main inputs – power and speed.
Once a test run is complete, I start the cutting. The engraver software chooses which pieces to cut and in what sequence, moving from area to area to allow the recently cut pieces to cool down as not to distort the material.
Once complete, I simply lift and shake the sheet material and the individual pieces fall out.
Fascinating to see these pieces coming to life in Corina’s work, with stunning result. A pleasure to be a small part of it.
