At Bower Ashton yesterday; spent almost two hours in Fabrication laser cutting. This was to make perspex versions of the three press-out toys (helicopter, trawler and ferry) to be used as bedside lamps and/or decorative lamps.
The assembly has been interesting, especially the helicopter.
- One pressing out the pieces there were several breaks, leaving sharp edges and points; I had several tiny cuts on my fingers.
- Press-out was far too hard, even without the breaks.
- All ‘bridges’, used – as with stencils – to hold the pieces in place on the perspex sheet, would need to be eliminated, they are the main problem preventing press-out.
- More breaking during assembly, leaving razor sharp points and edges.
- A large amount of waste material, acrylic and therefore Group 7 plastic, cannot be recycled.
The inevitable conclusion: this is not a viable project and should be abandoned, unless I can find a translucent sheet material that is not brittle and does not break and can be recycled.
