Knicks LED light, use of digital fabrication for design prototyping

This light was in the making for a long time and is now finally completed. See earlier post. Its design includes several digital fabrication processes like laser cutting (acrylic and brass) and rapid prototyping (gold-plated stainless steel) using Ponoko‘s distributed manufacturing system. All metal surfaces are gold plated taking advantage of Ponoko’s US based production hub which offers rapid prototyping directly into metal.

Its dimensions are: 600 x 150 x 710 mm and the light head holds four 1watt LED’s.

CAD to gold-plated stainless steel

Web-based fabrication has gotten even more exciting with a new material/process offered through the Ponoko system. Getting computer models ‘printed’ in 3D using online rapid prototyping processes is established but having the CAD parts arrive in stainless steel with a gorgeous rich gold coat is quite something.

This new material/process is offered through the US hub and is equally as easy to order as the 2d laser-cutting service. I found that dimensions ‘shrink’ slightly eg holes I had modeled as 3.9 mm turned out to be 3.4 mm in the finished parts. Being mostly stainless steel (with some bronze wicked into it) it proved very difficult to drill the holes to the right size. High speed drill bits (even titanium tipped) are blunt after drilling only 6mm deep. Reducing the speed from the recommended 1000 rpm to a third helped to improve their staying power slightly. I look forward to the carbon-nitride drill bit I ordered to finally finish the job.

These parts are for a new light using a mix of digitally fabricated and manually made elements. The ‘gold’ parts are intented to connect carbon fiber rods forming the main structure of the design.
