Top 3D printing designers discuss their approach to DfAM (Design for Additive Manufacturing)

While 3D printing has now been around for over thirty years, and some 3D printing designers have been exploring the technology since then, until recently, there was no clear-cut approach to fully exploiting the technology’s potential for near-limitless geometries. The recent rise in the adoption of the acronym DfAM (Design for Additive Manufacturing) – which collects under its umbrella a plethora of terms such as parametric and generative design, topology optimization, lattice structures and biomimicry – is an indication that these ideas are making their way into the creative collective consciousness.
As manufacturing firms and their engineers fully realize the need to create more intricate, parametric and generative shapes in everyday objects, in order to reduce weight and material consumption, designers and artists are tasked with pushing the boundaries of this approach to product development. Over the past few years, 3DPBM has had the opportunity to work with some of the most experienced designers who have embraced AM technologies from many different technological angles.
For this month’s Industry Focus, coinciding with Milan’s Design Fair (Salone del Mobile), we contacted some of these designers to learn which AM technologies and software tools they use to explore new approaches to DfAM. Whilst their answers vary, a significant preference for powder bed fusion technologies and Rhinoceros software does emerge, and they all confirm the will and effort to head toward the use of DfAM and AM to create optimized, finished, end-use products.
Janne Kyttanen (WTFVC) who was one of the first to imagine consumer 3D printing, is now working on a new process – 3DTi – to enable fast AM production. Arturo Tedeschi’s (A>T) – a leader in generative design and DfAM innovation – is presenting custom 3D printed earphones during Milan Design Week. Ronal Rael (Emerging Objects) continues to explore new materials – including ceramics – and DfAM through binder jetting and paste extrusion technologies. Other designers we contacted with but were not able to include in this interview for deadline constraints include Joris Laarman of MX3D and Daniele Cevola of Ocore, who are currently working on huge DfAM projects such as a 3D printed bridge (3D printed by laser metal deposition) and a full size sailing boat 3D printed by robotic extrusion of composite materials. There are many more in the following article whose experience can shed new light on the benefits of DfAM, so read on!

1. How did you get into 3D printing?
When I was a design student, we had to pick what we wanted to do for our final exam. That was 1999. Somebody was designing a chair, somebody was designing a lamp etc. I figured it was my last year, so I wanted to create something a bit more impactful. I decided to challenge global logistics instead.
My key question was if we could start from scratch, how would we make things so that not everything got dumped back into the oceans after their use? I created an augmented reality platform, fused with 3D printing.
All tactile products would be produced in a closed-loop ecosystem in the future with 3D printers and everything nontactile was left in an augmented reality environment. Say, do you really need to own a painting, if you never need to touch it? Isn’t an AR painting good enough in the future? The rest is history…”

5. WTFVC's latest projects
What the Future’s (WTFVC) first startup – Pixsweet – developed an entirely new way of serially manufacturing custom products through AM. Kyttanen called it 3DTi: 3D Thermo-injection.
Launched in 2016, Pixsweet was started as the pilot to test the-first-of-its kind 3D thermo-injection (3DTi) technology; an autonomous 3D manufacturing technology which enables translation of an image directly into a packaged 3D product.

At the end of the work, I sometimes put my geometry through Netfabb or Meshlab for cleaning it up. However, lately, I am really intrigued by the possibilities of using VR tools for modeling and designing. VR is a much more natural tool for creating in 3D.”

5. Alessandro Zambelli's latest projects
“The last work in order of time is MACROCOSMOS a collection of objects/vases that takes inspiration from the world of Sci-Fi.”
1. How did you get into 3D printing?
It all began when we visited the 2007 London Design Festival and we attended at the “Manufacturing Reinvented” conference at the Royal College of Art, with speakers including Dr. Richard Hague and Janne Kyttanen among others. When we came back to Barcelona, we applied to get a research fellowship granted by FAD Barcelona (Fostering Arts and Design), and we succeeded; that’s when we started our way through the AM and 3D printing world. We were lucky that we had the opportunity to learn everything of this disruptive technology from the beginning.
In 2009 we started Growthobjects with Dr. Jordi Bayer, becoming a group with the aim to offer customised design and biomimetic engineering solutions. With the goal of generating creative proposals through Direct Digital Manufacturing, we started providing international consultancy, new strategies and solutions in design and product development.”
2. What aspects of AM make it an ideal production method for your work?
For that, we have developed our own methodology for a new framework for product development and finding new customized products for niche markets. Now more than ever, product design is linked to the business model, brand identity, market strategy, among other disciplines. And so we face challenges where we need to apply all our creativity and AM possibilities, but sometimes we only need to solve a product for a unique piece or small batches, in both cases, design for AM is the best solution with regards to time, cost, and viability.”

3. What AM technologies do you prefer and why?
From the beginning, one of our favorite processes was laser sintering in polyamide, because of the absence of manufacturing restrictions we could apply design freedom and achieve impressive results based on the specific project requirements. We always exploit the potential of each process, understanding its possibilities, and pushing the boundaries from a design point of view and fulfill engineering requirements.”

5. Growthobjects' latest work
“Different activity lines, from custom projects and bespoke products to engineering and research, and also knowledge transfer and training.
GO recently created a hat for Axis service bureau, based in France, to express the potentials of the SLS technology through a stunning design that enhances its peculiarities and states its uniqueness. The design won the 2017 5th Singapore International 3D Printing Competition.
In collaboration with Origen Studio, GO has been developing creative web Fabapps for 3D printing unique products, with responsive custom design generation and web-based platform, offering pre-established possibilities for co-designing according to the features of each design.
GO also develop proposals, with the collaboration of AM companies. In collaboration with Mcor Technologies a design was developed that required the development of a new color algorithm and some software improvements for its AM system by the engineers of the company to succeed with the design fabrication.
A research project in progress is the challenge of an efficient AM tool design for plastic injection with complex cooling systems by water or air, by manufactured molds by Leitat Technological Center.
As a professor in Product Design and Engineering at the Elisava School of Design and Engineering in Barcelona since 2007, one of Xavi Tutò’s academic objectives is to provide the skills to improve the customer perceived value for the personalised products, based on a methodology of design work for AM and the definition of business models for the join delivery of products and services.
In the last course, students, Núria Diago and Maria Carrion, created a nose clip for synchronized swimming discipline, Be (in the) water, a piece that adapts specifically to the nose surface of each athlete. They received the second prize at Reshape international competition 2017.

3. What AM technologies do you prefer and why?
Thanks to solid filament, it is possible to use this kind of printer even in a closed office space. The printing result is easily cleanable as is waste management. Another advantage of FDM is the growing variety of materials, the extensive availability and it’s easily conserved. The technological limits of FDM printing are easily overcome with careful design, making it the best solution for desktop or office prototyping. While testing the different technologies, I was pleasantly impressed by the Multijet technology, especially with the pieces made using HP machines. “
4. What software(s) do you use to create and optimize your designs for AM?
1. How did you get into 3D printing?
For us 3D printing is the ultimate solution to bring our design approach to the real world. 3D printing is a very rapidly developing area, so experimenting with different tolerances and materials has become a natural part of our design practice. Without 3D printing, our digital poetry could not get a physical form.”
2. What aspects of AM make it an ideal production method for your work?
On the other hand, it is the variety of materials that are available on the market. You can prototype something by using cheaper materials and once the desired solution is achieved, you can move on to higher quality materials or even precious metals.”
3. What AM technologies do you prefer and why?
Usually, for higher-quality lightweight products we prefer SLS as the quickest and currently cheapest method with the biggest bounding box. In metal for sure, the LMF has given the most amazing results in surface quality. For large scale clay experiments we use LDM.”

“KE’LYFOS
kélyfos is a gramophone created for DWS. You can use it by inserting a smartphone for perfect sound amplification. It is composed of 8 pieces and exists as a “sculpture ” that must be observed at 360°, like a Nautilus with shell-like lines
Project Alux project was inspired by sea waves It is a lamp and also an acoustic box. Dimensions are cm. 25x30x30 that means this item is particularly difficult to 3D print by stereolithography. Alux was exposed at CES of Las Vegas (USA).
VESPA V98 is a revisitation of the motorcycle headlights of Italian “Vespa V98” new way to see the old but always actual piece.
Alice worked with stereolithography creating different pieces and assembling it, using DWS printing machine. It was exposed at Mecspe in Parma last March 2018. “Vespa V98 was an important step of Italian Design and I’m proud to have this piece in my collection of art objects,” Alice says.
Thank you so much to all the 3D printing designers that contributed to this expert roundup! If you enjoyed reading this post, share it on social media and help us spread the word about it.
