Further to my last blog, Preparing for Highlights, 2.
Yesterday, my first Ponoko laser cut pieces arrived and it was worth waiting for. After peeling off the protective sheet, that still showed the impact of the laser’s heat, clean clear pieces popped out of the cut Perspex sheet. I had used the clear 2mm thick Perspex material out of Ponoko’s material catalogue.
The edges are clean and appear almost polished and do not show, as I had expected, some ‘burn’ marks. As Ponoko suggests in their ‘starter kit’ the dimensioning of interlocking pieces might need a bit of fine-tuning, I found that while having a good fit the slots I had designed have been a bit too wide. This will be easily fixed in Illustrator, as I have in mind to get more of the same parts cut in different colours for further variations of this lamp.
These parts form the ‘head’ of the desk-lamp for which I had already made all other parts. The assembly was straight forward as everything, the rapid prototyped and laser cut parts fitted very well together. I used sandpaper to make the surface of the parts opaque as the clear was ‘too’ transparent. Now the LED’s make the whole head light up.
I am very pleased about the straight forward way Ponoko’s system enables me to include precision cut pieces as part of my designs. Living in Australia made it a three week turn-around-time which was somewhat testing. But I already look forward to the next shipment with parts that will combine laser cutting with laser engraving. Ponoko has great instructional videos about this on their site.
