LightArt Coil Collection: From Waste to Watts


After over two years of intense research & development, the Seattle based company ‘Lightart’ finally shared its new ‘Coil Collection’ with the world. An exciting, 3D printed series of new pendants created from upcycled waste. These distinct matte fixtures have a look and feel like pottery, spun and handcrafted. Unexpected from fixtures produced through additive manufacturing.

A Unique Merge of Design and Upcycled Materials Science

How can we make recycled content look as good as possible? This was the key question during the product development phase for LightArt’s founder Ryan Smith and his team: “This is where things started to get really challenging. When we first started, it did not look polished—it looked like what you might expect when you’re trying to turn garbage into something beautiful. But we kept following the promise of the process, and made something we’re so proud of.”

Materials science and design came together at the LightArt production studio, aiming to create a material that looks unique, custom, and unlike previously seen upcycled materials. Image courtesy of LightArt.

The new Coil Collection addresses a central question the industry is facing: What can we do with waste? The team worked with the engineering division of parent company 3form to figure out what the base material possibilities were, and pushed the boundaries in collaboration with other polymer companies across the US to tap into collective expertise and drive for innovation.

Upcycling Plastic into Pendants: The Coil Collection

LightArt’s Coil Collection is made from internal waste material, but the brand hopes to expand the practice throughout the industry over time, as the LightArt facility strives to become a manufacturer of goods that are net positive in climate, waste, and energy.

Visually Appealing Content, Curvatures and Distinct Geometries

The design team of LightArt aimed for recognized classic pendant shapes focused on distinct geometry and curvature with a matte finish, giving the fixtures a pottery-like quality. The textured finish, inherent to the additive manufacturing process, is complemented by subtle algorithmic adjustments to achieve a handmade, one-of-a-kind feel.

The LightArt tdesignersfinally chose seven elegant shapes, deliberately defining the endless options afforded by additive manufacturing to create a curated product with a distinct LightArt feel. Departing from what is expected from a 3D printed item, the form is textured, tactile, and unique.

Sustainable Innovation

In design, recycling and sustainable innovation cannot be the sole drivers for innovation —the product has to be attractive, too. LightArt wanted the color and aesthetic of the Coil Collection to have a distinct value. Sorting the colors of the waste through new technology, the company came up with a monochrome black and white palette for the pendants.

We at 3DPrinting.Lighting will keep following LightArt with great interest and report upon the availability of new and sustainable concepts!

Independent UL 3D Printing Research Study on Safety and Performance for 3D Printed Plastic Parts

Header image for blogpost UL 3D Printing Research Study at 3DPrinting.Lighting. Image and logo courtesy of UL

Underwriters Laboratories (UL), a leading safety science company based in Northbrook, Illinois, recently published its research findings detailing the effects of 3D printing on safety-critical polymer performance properties. The UL 3D Printing Research study findings have been used to develop a framework for evaluating and qualifying materials, helping stakeholders across the additive manufacturing (AM) supply chain to mitigate risk and deliver quality and performance.

UL 3D Printing Research Study

The key topics UL investigated include flammability, ignition and electrical properties of samples that were 3D printed against samples manufactured using conventional, injection-molded methods. UL Researchers identified significant safety and performance variations and concluded that performance ratings from traditional manufacturing techniques cannot be applied when the same material is used in a 3D printing process to print a 3D part.

UL Blue Card Certification Program

In response, UL has developed a certification program for plastics for additive manufacturing (Blue Card), The UL Blue Card presents the data necessary to ensure the integrity and usefulness of materials intended for 3D printing and 3D printed components and products. A Blue Card is automatically issued when a material intended for 3D printing receives a UL Recognized Component Mark.

“UL Researchers identified significant safety and performance variations and concluded that performance ratings from traditional mFG. techniques cannot be applied IN 3D pRINTING”

UL Certified AM materials are published in UL’s publicly available Product iQTM database, making them searchable to thousands of manufacturers looking for a certified 3D material. By using an independently tested and certified 3D material, end-product manufacturers can save time and money certifying their end-products or systems. As Blue Cards are specific to a 3D printer, a 3D printer manufacturer can also certify material for explicit use on his equipment.

Certified Plastics for AM Whitepaper

Read UL’s white paper ‘Certifying plastics for additive manufacturing’ to get an overview on UL’s research. A copy of the detailed research study is available for download, in addition to the study ‘Processing the Future of Additive Manufacturing‘ that was published back in 2018.

Back in 2015, UL published its first compliance guideline, titled “3D Printing & Additive Manufacturing Equipment Compliance Guideline” as well as its “E-Learning Program teaching the basics of 3D Printing“.

Header image for blogpost on 3DPrinting.Lighting for new Ammunition collection at Gantri

Designed by Ammunition and made possible by Gantri’s radical approach to manufacturing, three new collections of lighting are now available for people seeking a better approach to design, craft and sustainability as they shape and illuminate their spaces. Named ‘Carve’, ‘Gio’ and ‘Signal’, the three collections are inspired by Gantri’s 3D printing platform and the intricate, organic and unexpected possibilities it provides compared to conventional manufacturing.

The Collection: Designed by Ammunition – Fabricated by Gantri

Sustainably produced using a corn-based material and manufactured in California, each light is 3D printed on-demand, hand-assembled and finished, in a process that feels less like industry and more like artistry.

Featuring table, floor and wall-mounted lights, the lighting range includes next collections:

1. Signal Collection

The Signal collection features louvered slats that are fused to the main body of each light through 3D printing technologies. The slats were inspired by the functional aspects of exterior architectural louvers used to bring light and air inside.

2. Carve Collection

The Carve Collection’s monolithic forms and seamless surfaces feel carved from stone rather than assembled like conventionally manufactured objects.

3. Gio Collection

The Gio Collection is inspired by Italian Lighting Designs of the 1970’s that sought to remake and refresh historic archetypes through new materials and processes. The unique character of the lights came to life by manipulating and rationalizing classical geometric elements so they interact with each other in playful ways.

Ammunition and Gantri Designer Toolkit

In addition to bringing floor and wall lighting into the Gantri platform, Ammunition also worked together to create an improved process and toolkit that makes it easier for any designer to make use Gantri. This major update offers designers the freedom and flexibility to create while maintaining Gantri’s high standards for materials, additive manufacturing, packaging, pricing, shipping, and user experience.

Availability Ammunition 3D Printed Lights:

The collections are available for purchase via Gantri’s online marketplace.

Header image used in blog about Plumen 3DP biodegradable fixtures at 3DPrinting.lighting

In its latest designer collaboration with Batch.works, UK start-up Plumen pushed the boundaries of sustainable design to bring a range of 3D printed lamp shades to the market. The shades are made by using recycled plastic filaments from water bottles, fridges and other sources of plastic pollution. Here are some further introductions to the stunning decorative lighting collection of Plumen 3D Printed Lamp Shades.

Collaboration with Batch.works

Batch.works was established back in 2016 by former architect Julien Vaissieres. The aim of his newly invented company has been to create affordable and eco-friendly products, making the most out of 3D printing, most notably its speed and efficiency. Recently, Batch.works cooperated with five different design studios to create the Plumen 3D Printed Lamp Shades collection. The collection was inspired by everything from the Bauhaus movement to geometric forms of the Art Deco era.

Here are some of the highlights of the Plumen 3D Printed Lamp Shades Collection:

‘Ribbon’ features a fluid surface that bends over itself. The space created within the shade is filled with light, revealing and emphasizing the different volumes created by the enveloping surface. The vertical lines that run through the shade, combined with the horizontal layers characteristic of the 3D printing technologies used, amplify the idea that a piece of textile has solidified around the light to direct and enhance it.

NEO by Matthias Lauche

One other pendant fixture in the 3D printed range, named ‘Neo’, is based on geometric forms of the Art Deco era. Its designer, Matthias Lauche, has been taking familiar, historic shapes and cast them in a new role using 3D printing. Two shades stack on top of one another to fit and frame Willow’s delicate silhouette. The dual nature of the shade means several color combinations are possible.

The colorful HIVE shades work to frame the bulbs, allowing their beauty to shine through, while also taming the glare of their naked light. Together, they become a unified and natural objet d’art. Images courtesy of Plumen.

Biodegradable materials: Recycled and Recyclable

The new Batch.works lampshades are all made with a filament supplied by Amsterdam’s social enterprise Reflow, which recycles and repurposes plastics that would otherwise be sent to landfill or incinerated. They’re also 3D printed to order at Batch.works, significantly lowering the amount of produced waste.

Closing the life cycle of the design, when you’re finished with them, they can be recycled with the rest of your domestic plastics, ready to be reinvented once more.

We’re delighted to see inventive start-up companies like Plumen breaking a lance for biodegradable lighting solutions. So Signify did with launching its recent services for tailormade 3D printed luminaires using recycled CD’s to create distinctive light shades for its users to demand.

We’ll keep following the Plumen team with great interest, keep our eyes open and inform you about further releases in 2020…

SU University Researchers Develop Projection Lens Oscillation Process for 3D Printing Microlens Arrays

Image of 3D printed optical lens array by Luximprint used as header image for blog post on DLP 3D Printing lens arrays

Recently, researchers from the Singapore University of Technology and Design and Southern University of Science and Technology in Shenzhen, China, announced a breakthrough in the digital fabrication of microlens arrays using oscillation-assisted Digital Light Processing (DLP) 3D printing method.

To date, producing microlens arrays has proven to be difficult, according to the researchers. The current manufacturing technologies are time- consuming, have high process complexity, have a lack of fabrication flexibility, and face difficulty in consistency control.

Now, using a novel process of projection lens oscillation, the research teams have been successfully testing an approach for producing microlens arrays with proper surface smoothness using DLP 3D printing. 

Micro Lens Arrays – A gentle Introduction

A microlens array (brief: MLA) consists of multiple micron-sized lenses with optical surface smoothness. An MLA has a supporting substrate with often individual lenses of about 10 micrometers on it. It is formed in a one-dimensional or two-dimensional direction. Today, MLA’s have become an important micro-optics device used in various compact imaging, sensing, and optical communication applications.

With the exception of Netherlands based Luximprint, a global leader in Additive Optics Fabrication, most traditional 3D printing methodologies have been unsuccessful in fabricating any optical component thus far, due to the presence of coarse surface roughness in 3D printed objects.

Projection Lens Oscillation

In this new approach, the computationally designed grayscale patterns are employed to realize microlens profiles upon one single UV exposure which removes the staircase effect existing in the traditional layer-by-layer 3D printing method, and the projection lens oscillation is applied to further eliminate the jagged surface formed due to the gaps between discrete pixels.

Digital Light Processing for Details

DLP 3D printing is a process that uses a digital projector to cure photopolymer resin and produce 3D printed parts. It is often used for highly detailed 3D printing, and is considered a faster method than Stereolithography, a similar 3D printing process. Although DLP 3D printing offers great flexibility in the fabrication of microlens arrays with different sizes, geometries, and profiles, it has been unable to produce parts with optically smooth surfaces. 

Oscillation DLP Printing: Ultrafast & Flexible Fabrication Method

To overcome this, the SUTD and SUSTech researchers suggested integrating DLP 3D printing with mechanical oscillation and grayscale UV exposure. Oscillation helps to remove the jagged surface formed by discrete pixels in a 3D printed part, whereas the grayscale UV exposure removes the staircase effect common to 3D printing, where layer marks are visible. The result is an ultrafast and flexible fabrication method for microlens arrays with optical surface smoothness. 

3D Printing Smooth Microlenses

Although the research team has specifically adapted DLP for producing microlens arrays, various other 3D printing technologies are already suited towards its production.

For example, Germany-based Nanoscribe manufactures two-photon additive manufacturing systems that are capable of producing microlens arrays.

Also, for larger types of lens arrays, Dutch service provider for printed optics Luximprint offers optical quality lenses straight from the printer with zero need for post-processing.

Economic Viability & Effectiveness

To prove the viability and effectiveness of the approach, the research team has conducted detailed morphology characterizations, including scanning electron microscopy and atomic force microscopy. Results suggested that the integration of projection lens oscillation with DLP 3D printing reduces surface roughness from 200 nm to about 1 nm.

Wrapping it all up, we may fairly conclude that, although the new DLP 3D process is still under investigation and not commercially available yet, the initial results are promising, and we can’t wait to see the first 3D printing devices entering the market.

NOTE: The SUTD + SUSTech Study, Ultrafast Three-Dimensional Printing of Optically Smooth Microlens Arrays by Oscillation-Assisted Digital Light Processing, was initially published in ACS Applied Materials & Interfaces.
