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.

This post describes some technical and making aspects of the Light objects for the ANU School of Art library. You can read more about the design aspects here.
During the making of these lights a mix of manual and digital fabrication processes have been used. Brass and aluminium pieces have been laser cut while the translucent red elements had been rapid prototyped by ‘Rapid Pro‘ in Victoria, Australia.
The black curved arms are five 2.5mm layers aluminium, riveted together to create an inside channel concealing the cables up to the brass cylinder. They have been laser cut locally in Canberra by Acuform. The cylinder forms a central hub from which four conical carbon fiber tubes stretch out and support two light heads on each lamp. The lights have a wingspan of 1.4 meter.
Each light head has six one-watt LEDs. The LEDs are mounted on a decorative brass cooling plate (cut by Ponoko) and are cooled by a fan. The following parts had been used: LED ring with six one watt LED (LSP6-WW-XXX) and Controller/Driver (MDU9-SC-3570) from Future Electronics. All elements are enclosed by ABS housings. These housings are rapid-prototyped using translucent red FDM material from ‘Stratasys’.

The electronics – led drivers and fan power supplies – are placed inside the void between the column and the main brass fitting. The 12 volt fans are driven by 6 volt power-supplies letting them run without developing noise. Before the installation the lights had been tested for several days.

In December 2009 I installed two light objects in the library at the ANU School of Art. Please find a post about the making of these lights here.
These two lights provide four ‘highlighted’ spots for reading or lab top use within the reading pit. The design intent was to connect the space inside the glass walls of the reading pit with the surrounding architecture. The objects themselves should have a mechanical but yet organic feel to them. I used the two columns on either side of the reading pit as anchor points from which the lights reach over the seating area in a ‘branch and twig’ fashion. All brass parts of these lights – being cylinders of sorts – referring to these columns. The lights are lightly strapped to the columns highlighting their light weight construction. The colours have been limited to Brass (gold), black and red.
The lights are made of aluminium (powder coated black), brass, carbon fiber tubes and LEDs.

This image shows some of the possible combination of materials and colours I played with for the 2nd series of this light object. Basically all 3mm materials could be used as a base. Ponoko has many exciting colours in their materials catalog.

Based on web 2 technologies, a growing variety of production processes are becoming easily accessible for anyone.
An online interface makes highly specialized technologies available. Once you setup your account, payment and shipping options are selected you can start producing and in some cases have access to a network of like-minded users or potential customers.
Companies like Ponoko (laser cutting and engraving), RedEye (Rapid Prototyping) and blurb (bookmaking) can successfully contribute to a designer/maker practice. A competent level of computer skills are required to address these services to achieve the best outcome. For waterjet or laser cutting, which are essentially two dimensional processes, of flat or sheet materials the mastery of a vector-based graphics program like Adobe Illustrator is essential. To use the RedEye ‘factory of the future’ one needs to generate a .stl file of a virtual 3D object that had been modeled in a CAD program.
The underlying specialized technology, for a long time the domain of the manufacturing industry, is expensive and usually out of reach of a single craft practitioner. If acquired, such equipment would ‘tie’ the individual maker to this technology for a long time and introducing a high level of risk to their business. Not to mention high running cost and that these digitally based technologies become obsolete within a few years.
I have used several of these processes while designing and making the ‘desk light‘, it has a waterjet cut stainless steel plate, a lasercut lamp shade (Ponoko) and Rapid Prototyping parts. Using these technologies has led the design process to new solutions and made the making of this light relatively easy.

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.
Peeling off the protective layer
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.
Prototype put together
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.

I just put together the prototype of a desk-lamp. This object uses polished stainless steel, ABS plastic (rapid prototyped parts), an aluminum tube coated with carbon fiber, laser-cut Perspex and 3 warm white 3 watt LEDs.
Desk lamp computer rendering
For the first time I will use a net based producer for part of the making process. Most of the lamp’s head part – the laser cut Perspex – will be produced by Ponoko . A clever (company) setup that laser cuts and laser engraves materials based on ones own design. Ponoko’s well working website makes it easy to get started. From selecting the materials to producing the right file formats for cutting and/or engraving all is explained in easy to follow steps. I am eagerly awaiting the first shipment of the 2mm thin cross-sections for the ‘reflector’ part of the lamp’s head.
After modeling the lamp shade as a ‘solid model’ first in CAD (formZ) I then sliced it into the cross-sections, these sections were then imported into Adobe Illustrator and saved out in the right format for Ponoko’s processes.
- Cross-sections for laser cutting
Before uploading the file to be laser cut, I printed and cutout the Illustrator outlines and put together a mock-up of the lamp shape to see if I like the design and to get an idea if the pieces fit together.

Computer simulated lamp head
I also rendered a simulated view of the final head-piece as well as the whole desk lamp. I hope the final ‘real’ object will closely resemble this simulation.
