I designed this light object with the idea to further integrate web2 based fabrication with my craft practice. The shade, base and fixture for the light emitter (LED) are all laser cut by Ponoko. I look forward to try a variety of materials for the base including acrylic using ‘iMacy’ colours, bamboo and metals. The shade is white felt or polypropylene.

The shade simply snaps into the base and forms a dome covering the warm-white 1 watt LED. A metal fixture holds the LED the switch and functions as cooling surface.

Environmental aspects of this object: The LEDs used are highly energy efficient and have an expected life span of about 5 years of continuous operation till reaching 70% of their original brightness. All parts can be dissembled for recycling.

Anyone interested in web2 based fabrication, here is a ‘growing’ collection of bookmarks. You will need to have a ‘delicious’ account though. If you are logged onto ‘delicious’ search for designartsanu and you will find these links.

bookmarks for designer maker

These links are added for their relevance for making things from digital files eg images, text, vetor-based drawing (Illustrator) or 3D files in .dxf format. I have referred to these services in earlier blogs about making a catalogue or a light object. If you know about any further relevant links please let me know and I will add them.

While sorting photos of a recent exhibition using iPhoto on an Apple Mac I explored the ‘book’ option in this free software. After selecting one of the many layout templates it was easy to populate the pages with images. The basic image editing tools in iPhoto also helped to improve the look of the pictures significantly. After tweaking the templates and adding the images and some text, I only needed to press the ‘buy’ button and through my Apple account the prove of my catalog was on its way to be printed. This is just another example of a web2 based production method.

iPhoto book interface

The price of about $25 (Australian) for each copy is good if one needs only a few copies instead of hundreds to make a traditional print-run viable. I also used a pdf export of this catalog to get 20 copies printed locally, the price was comparable but the quality of the ‘Apple’ print was superior. You can download (500KB) a low res pdf of this catalog.

I have now a lasting document that helps with promoting my work and a little giveaway for everyone who supported my work. In the process I also registered as a publisher and this booklet has an ISBN. This might sound like a lot of effort for a little 30 page publication, but this catalog documents my recent ‘highlights‘ exhibition, which in turn represented the outcome of an intensive period of research and work as part of my professional practice.

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.

My first solo exhibition since 2001 called ‘Highlights’ opened in February 2009 at Craft ACT in Canberra and then in May at Metalab, in Sydney. Many thanks to Catrina Vignando, general manager Craft Australia and Grace Cochran who have opened those shows respectively. Highlights represents a change in my practice with the focus on light objects as well as highlighting how combining making processes (manual, digital and distributed) can address the designer/maker model as a contemporary approach to craft. See earlier post of the design/making of the light ‘Desk 30′.

The exhibitions were well received and successfully set up by Jason Hugonnet, curator and exhibition manager Craft ACT and Cesar Cueva, director of Metalab. Please find Jason Hugonnet’s exhibition review here.

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.

Opaque surfaces

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.

Responding to a call to participate in the APM (Accredited Professional Member) exhibition by CraftACT with the title Interior Exterior I decided to make a light object. This show will open on Thursday 18 September at 6PM. Taking the dualism in the title as a starting point I used a warm light (1watt LED) representing the interior and a cold white LED as its counterpart. Both lights are directed towards each other and shinning onto a slightly curved transparent screen. See image of a few preliminary drawings for this object.

This screen is the membrane separating the inner from the outer. At this screen the different light qualities mix or fuse. Interestingly you can see the cold white on the ‘warm’ side of the screen and visa versa.

However when I started to model the components for a simulation on formZ (CAD) it became apparent that ‘all that stuff’ I needed to hold the elements in place was distracting form the pure, initial idea. What are now little cubes housing the LEDs were various (failed) designs going from bad to hideous. Even the cubes I have now are somewhat a compromise. Also the base-box which is capped by two alu plates and a white rapid prototyped frame feels like a necessary compromise to me. It contains the switch, driver and an additional LED (360 degree), which illuminates the base lightly from the inside.

First I wanted the top alu plate to be in mirror-polish but this particular alu piece I used had too many inclusions creating the occasional streak in the otherwise polished surface. To hide these streaks I used the new high tech Ink jet printer at the ANU School of Art , it can print on anything up to 40 mm thick with ink. The ink is then cured (baked on) with UV light. (One of our staff printed on a room door). The pattern I got printed onto the alu was derived from a piece of white sandpaper scanned in then the image was inverted and finally a ‘chrome’ filter in Photoshop applied. I usually avoid filters and effects at all cost but this pattern seemed to be able to run from the interior to the exterior section of the object without problems.

Now that this object is together and shines when switched on it has grown a little on me, but still it is an object that is neither a lamp nor a sculpture. Maybe, if I find the right (friendly) term for it it will settle into its place. Materials: Aluminium, ABS plastic, LEDs. Dimensions: 100 x 100 x 95 mm

Since yesterday I am on ArtFlock thanks to Sharon and Amy who got me there in the first place.
I will be interested in the responses I might get to my works in this art and craft related (web2) space. The first work I uploaded is the DP bowl, this piece is part of a body of work that uses mathematical formulas I manipulated as their source. Despite a lot of technologies involved in creating this object there is a significant amount of manual work necessary to get this work finished, both on the keyboard as well as on the workbench. Tomorrow, 5th September 2008, will be the opening of Digitaler Formenschatz at the Galerie Handwerk in Munich, Germany. This exhibition intents to show the impact of new technologies on and the response to these by makers and the crafts in general. I have six related works on display at this show.

I got this 1.7MB PowerPoint file attached to an email showing a series of stunning images of the earth from space. I particularly enjoy the images showing the shadow line between day and night.

BlueBeauty 1.7 MB slide show might take a while to download.
The last slide motivates the viewer to ‘send’ this file out wide. I am not sure as to who owns the images, as only agencies like NASA or ESA could capture such images, so the intellectual property might be an issue with this PowerPoint file. If it is a NASA image then there seems not much of a problem here.
