Glow Box – A Window into an Artificial Mind


Glow Box, a project by Yeseul Song & Michael Simpson, is a 3D printed hybrid object which imbues life into the object by displaying a real-time visualization of a neural network as it works to solve problems. The installation exploits the organic-like nature of the neural network algorithm and combines this with the almost magical ability of the physical object to appear illuminated without apparent electricity. The result is something which blurs the distinction between real and virtual imploring the viewer to question this distinction altogether.

Glow Box – Inspired by Nature

Nature has inspired mankind as longack as history is recorded. Among other things, our tools, techniques, and even aesthetics derive so much of their form and function from the clever decisions arrived at through centuries of evolution.

In more recent years, Nature has become a direct source of strategy for designers and researchers tackling some of the world’s most challenging problems. The neural network, a core component in deep learning, is no exception to this grand tradition. In their simplest form, a neural network models the high-level behavior of neural perceptrons. Essentially, they implement the basic functioning of a living brain. This technique has become invaluable in resolving problems that were once extreme challenges to quantify and compute.

Evoking Curiosity and Questioning Hybrids

But, categorically, what is a neural network? What do they look like? Do they think like we do? The ubiquity of these AI techniques begs for a more critical and creative understanding of the algorithms themselves. This project strives to do so by presenting viewers with a real-time window into the mind of a neural network as it repeatedly attempts to prove a simple equation. In particular, Glow Box evokes curiosity and, potentially, a questioning of the role for analog-digital hybrids as they inch closer and closer toward invalidating accepted definitions of sentience and free will.

3D Printed Glow Box – The Making Of

The cube itself was algorithmically designed and then fabricated using Stratasys Polyjet 3D printer. The cube has dimensions of 6” x 6” x 6” and is printed in optically clear material (Vero Clear) which exposes the object’s internal structure. On the contrary to optically clear print resins, that may result in printed optics or other geometrical shapes with a fully transparent internal core and a smooth surface finish, the higher haze values of the Vero Clear materials are utilized to absorb the emitted light.

Inside the walls of the object, a matrix of conduits curve to connect the cube’s bottom surface to the front-looking face of the object. These conduits hold thousands of strands of optical fiber which redirect light from beneath to be emitted from the front. This allows the analog object to serve as a sort of display when an image or animation is projected onto the cube’s bottom.

Lighting Research Center Industry Collaboration to Explore 3D Printing Solutions for Lighting Professionals

Header image of article about LRC collaboration on 3D printing for the Lighting Industry

How will 3D printing affect my business? This question is being asked by companies in several industries, especially those involved in the manufacturing process. A diverse group of companies came together last month to discuss and better understand the impact of 3D printing in the lighting industry. 3D printing, also known as additive manufacturing, is already being used in several industries to augment conventional manufacturing.

3D Printing – Understanding the Impact on Lighting

The discovery workshop, organized by the Lighting Research Center (LRC) at Rensselaer in partnership with Carbon Group Global, was designed to understand the impact of 3D printing across all areas of buildings and construction, and especially its impact on lighting. A group of industry leaders focused on how to best assimilate 3D printing with the lighting industry, the mutual benefits to all stakeholders, and the implications to and the impact on the existing ecosystem. The group will soon embark on developing an industry roadmap to make additive manufacturing a viable option for the lighting, building, and construction industries.

The Benefits of 3D Printing for Lighting Professionals

The potential benefits of 3D printing include the ability for manufacturers to create custom products that are uniquely designed for spaces to be illuminated. Fixtures could be printed on-site and on-demand, benefitting the user/customer, the manufacturer, and the local construction industry.

3D Printing Individual Solid State Lighting Components

With 3D printing, the manufacture of individual lighting components, such as heat sinks, electrical traces, and led optics, could be customized, enabling the design of parts that cannot be manufactured today by traditional methods, improving both aesthetics and functionality.

Research is still needed to advance the integration of 3D printing into the lighting industry, beyond the current prototyping stage. To date, the Lighting Research Center has conducted initial investigations into the potential for printing thermal, electrical, and optical components.

100 Times Faster 3D Printing with Light

Image of 3D printing with light with logo of Michigan University on it

A new, unconventional approach by Michigan University to 3D printing creates stunning results in an up to 100 times faster 3D Printing process. The newly invented methodology was recently reveiled and rather than building up plastic filaments layer-by-layer, it lifts complex geometrical shapes from a bath of liquid resin at up to 100 times faster 3D printing than conventional printing processes do. Here are some deeper insights.

3D Printing: A Game-Changer for Manufacturing

3D printing could potentially change the game for relatively small manufacturing jobs, producing < 10,000 identical parts. It would mean that the objects could be made without the need for a mould tool, coming with a significant upfront investment. But the most familiar forms of 3D printing, which are sort of like building 3D objects with a series of 1D lines, hasn’t been able to fill that gap on typical production timescales of a week or two. Scaling towards larger volumes has only been possible by multiple printers in parallel, each of them duplicating the same approach, what is not very efficient.

Printing Optics at Speed

As far as we are aware, it’s been thus far only the process of 3D printing optics, that has basically evolved from UV-inkjet printing, that can produce parts at such high speed and has the potential to scale to larger manufacturing quantities. This process, however, is fully tailored for additive fabrication of custom optics and Optographix and does not offer commercial solutions for other markets, as far as we are aware.

The Michigan University Approach

The Michigan University method solidifies the liquid resin using two lights to control where the resin cures – and where it stays liquid. This enables the team to solidify the resin in more sophisticated patterns. They can make a 3D bas-relief in a single shot rather than in a series of 1D lines or 2D cross-sections.

By creating a relatively large region where no solidification occurs, thicker resins – potentially with strengthening powder additives – can be used to produce more durable objects. The method also bests the structural integrity of filament 3D printing, as those objects have weak points at the interfaces between layers.

An earlier solution to the solidification-on-window problem was a window that lets oxygen through. The oxygen penetrates into the resin and halts the solidification near the window, leaving a film of fluid that will allow the newly printed surface to be pulled away.

But because this gap is only about as thick as a piece of transparent tape, the resin must be very runny to flow fast enough into the tiny gap between the newly solidified object and the window as the part is pulled up. This has limited vat printing to small, customized products that will be treated relatively gently, such as dental devices and shoe insoles.

By replacing the oxygen with a second light to halt solidification, the Michigan team can produce a much larger gap between the object and the window – millimeters thick – allowing the resin to flow in thousands of times faster.

The Resin: Key to Success

The key to success is – like in many other (3D) printing processes, the chemistry of the resin. In conventional printing systems, there is generally only one material reaction. A photoactivator hardens the resin wherever light shines. In the newly invented Michigan system, there is also a photoinhibitor, which responds to a different wavelength of light.

Rather than merely controlling solidification in a 2D plane, as current vat-printing techniques do, the Michigan team can pattern the two kinds of light to harden the resin at essentially any 3D place near the illumination window.

Soon, a research paper describing this approach will be published in Science Advances, titled, “Rapid, continuous additive manufacturing by volumetric polymerization inhibition patterning.”

Final Thoughts

As described before, the process invented by Michigan University reminds us very much about the invention of ‘Printoptical Technology’ (3D printed optics) by Luxexcel back in 2009. We are greatly interested to learn whether this novel approach would bring new approaches and/or synergies to the table, especially related to applications in the Lighting Industry. In any case, we will be following the developments around the innovation with great interest!

LPS 2018: Springboard to the European Lighting Industry

Choosing ‘LED professional Symposium + Expo’ along with the co-located ‘Trends in Lighting’ event as a launching platform has been a strategic decision for Luximprint. Among the European Lighting events, LPS and TIL take a leading position in bringing the latest strategies related to new technologies and digitization closer to market professionals. It provides both engineers and designers of lighting systems a unique platform for new fixture development.

“Presence of digital manufacturing technologies is key, as it significantly contributes to improved system engineering and finally a healthier industry”.

Additive Optics Fabrication

Printed optics has come a long way in the lighting industry. Additive Optics Fabrication, marketed over the recent years by Luximprint, is a future-proof methodology of rapid prototyping custom LED optics by means of digital fabrication technologies. Direct ‘CAD-to-Optic’ manufacture avoids costly and uncertain commitments related to conventional optics manufacturing processes in the early development stages, such as upfront tooling investments and minimum order quantities.

Printed Optics by Luximprint were introduced at LPS 2018 to an audience of lighting system designers and engineers.

Printed products find their way find their way in a variety of engineering and (temporary) project applications, such as general lighting, (light) art, event- and interior design. Luximprint solutions serve mainly inspirational and functional demonstration purposes, as well as mold-/concept validation and pre-series fabrication.

Optographix: Optical Translucency for Branding and Interior Design

In addition to functional optical plastics, so-called ‘Optographix’ – as the name suggests a unique combination of optical translucency and full-color graphical expressions – are initially proposed at this years’ events to trigger lighting and interior designers.

All of the Lights Installation by Budmen Industries


Illuminate your Imagination: 100 Unique 3D Printed Lamps Installation by Budmen Industries

‘All of the Lights’ by Budmen Industries is an immersive light installation including 100 unique 3D printed lamps. It acts as a unified display of individualism. The project represents a bright future where individuality is celebrated and reflected in environments that are as unique and complex as we, human beings, are.

Hand-crafted Digital Designs

The All of Lights installation redefines 21st century craft by combining art sculpture and digital fabrication. To attach a personal and human element to each of the designs, the designers decided to digitally sculpt each lamp shade by hand.

Image of All of Lights installation by Budmen Industries with individually crafted lamps
During the process, a variety of form families appeared while the personality of each lamp remained unique.

Following the designers’ unique approach, a great variety of different shades was created, each reflecting unique personalities. Some were symmetrical and had a pure geometrical appearance, while others were more gestural, feeling like captured motion. Or they were swirled and stretched into splendid spirals.

3D Printing Large Luminous Layers

In fact, 3D printers can build hundreds of identical objects but their real strength is in making hundreds of different objects at no extra cost. 3D printing is a shift from a world full of mass manufactured products to one where each item can be a unique reflection of our individuality (called ‘mass customization‘)

Large Luminous Layers

A 3D printer creates objects layerwise. This process of stacking layers produces surfaces with striations similar to those seen on rock formations and tree bark. Printing with thick layers produces even more dramatic striations.

Illuminated Layers as Project Signature

Where for some applications the layering might be a limitation, the Budmen designers decided to see and use it as an charismatic feature of the process. The uniquely layered aesthetic is not only a process signature, but the object takes on an entirely new character when illuminated.

The Brains behind Budmen Industries

Budmen Industries was founded by Isaac Budmen and Stephanie Keefe. Budmen is an artist, designer and ‘lifelong inventor’ as he describes himself. His creative work exploring digital fabrication has been featured at leading museums and other venues.
