I printed this ventilated fingertip protector after an injury with a power tool left my finger very sensitive to knocks and bumps. I wanted the protector to be ventilated to allow air to circulate to help prevent infection.

I didn’t need it to be pretty so I printed at 0.2mm with no supports. I opted to use a raft.

3D Printing Used to Decorate Biodegradable KOFFINs that are Personalized for the Deceased

While the way we live is vastly different from the way we did 100, 50, and even 20 years ago, the way we say goodbye to loved ones when they’ve passed away is still pretty much the same. Funerals are not easy for a number of reasons, but the last thing on anyone’s mind should be the cost of these emotional events and ceremonies; unfortunately, that’s not often the case. According to SunLife, funeral costs have shot up over 70% in the last decade.

With this in mind, Koffin, a Liverpool startup founded by artist Gina Czarnecki in 2014, is working with business program LCR 4.0 and using Industry 4.0 technology – specifically 3D printing and advanced material testing – to help cut down on the cost of funerals with customizable, biodegradable eco-coffins.

“Funeral prices are increasing drastically, and people deserve the right to a personalised send-off that isn’t going to break the bank. Planning a funeral can be a difficult time, but we’ve found that having something tangible to take control of and make your own improves people’s wellbeing and peace of mind,” said Czarnecki.

“The work with LCR 4.0 has enabled us to test our design that creates a cost-effective alternative that emits less CO2 emissions than a natural plant.”

Together with brand consultant Clare Barry, Czarnecki set out to redesign the coffin – typically a narrow wooden box. But a KOFFIN, according to the startup’s website, is “a light, eco-friendly capsule made from bioplastic,” which is definitely different from the more traditional, pricey Victorian-style coffins we’re used to seeing.

“The way we currently bury or cremate our loved ones is poisoning the earth,” the Koffin website states.

“Besides… your funeral is your last hurrah, right?

“…So shouldn’t your coffin be as unique as you are?”

The 100% biodegradable KOFFINS were created to help people take back their rights to a personal, affordable funeral. They are made with a lignin-based biopolymer and don’t require any glues or metals to hold them together. They produce less ash residue than other coffins, are leak-proof without having to use wax linings, and will decompose in the earth just like natural tree wood. Additionally, the oval capsules can be completely personalized with different colors, hand-written messages, photographs, and a variety of attachable, 3D printed decorations.

During the development of the KOFFIN prototype, the startup was in need of expert technical support during testing. So Koffin turned to LCR 4.0, partially funded by the European Regional Development Fund, and its partners Sensor City and Liverpool John Moores University to test its inexpensive, sustainable prototype, and use 3D printing for added personalization.

“Koffin is unlike any other start-up that we’ve helped to date,” said Jaime Mora-Fernandez, LCR 4.0 product design engineer at Sensor City. “The work carried out illustrates how new technologies can help businesses in a wide variety of sectors transform the way they approach the design and manufacturing process.”

The LCR 4.0 team at Sensor City helped Koffin complete a finite element analysis (FEA) of the design to find the right material thickness to withhold sufficient pressure. This helps reduce material costs, which will trickle down to lower consumer costs. Then, the partners tested the prototype, and completed a report that concluded the material’s thickness would be robust enough for its purpose.


After four long years of development, the startup has officially gone into production with its first run of biodegradable, customizable, eco-friendly KOFFINs.

“Our involvement with the LCR 4.0 scheme has resulted in outputs being produced in a timely and efficient manner, using expert advice and linking disciplines seamlessly,” said Czarnecki.

Starting today, 20 of the KOFFINs, decorated through a national public call-out, will be displayed at the Oratory, next to the Anglican Cathedral, in Liverpool; some of them even bear some interesting 3D printed decorations. Soon, the startup will also launch a Kickstarter campaign in order to raise the necessary funds to take the KOFFINs to market.

 

This isn’t the first time that 3D printing has been utilized in the death care industry. We’ve seen 3D printed urns, 3D printed busts of the deceased, and even 3D printed jewelry made from the ashes of our loved ones. As 3D printing also comes into play often with sustainability efforts, the KOFFINs seem to be a perfect mix of life and death.

FEM Simulation Used to Test Mechanical Performance of SLS PA 12 3D Printed Objects

In a paper entitled “Mechanical performance of polymer powder bed fused objects – FEM simulation and verification,” a group of researchers discusses the importance of accommodating anisotropic behavior in 3D printed objects. Geometrical optimization is needed so that the object meets pre-set strength and quality requirements. For the study, a material description for polymer powder bed fused or selective laser sintered PA12 was investigated using the Finite Element Method (FEM).

Test specimens in the shape of dumbbells or dog bones were 3D printed, and material tests were carried out. The model was then used to simulate and predict the mechanical performance of SLS 3D printed lower leg prosthetic components: a pylon and a support.

“It was found that the FEM simulations, together with the Material Model, gave good estimations for the location of a failure and its load,” the researchers state. “It was also noted that there were significant variations among individual SLS printed test specimens, which impacted on the material parameters and the FEM simulations. Hence, to enable reliable FEM simulations for the designing of 3D printed products, better control of the SLS process with regards to porosity, pore morphology and pore distribution is needed.”

Two parts of a lower leg prosthesis were 3D printed: a pylon and a support. For the FEM analysis, ANSYS software was used. Topology optimization was carried out to find the optimal geometry of the two parts.

“For topology optimisation, the two load cases were created and linked to a topology optimisation module,” the researchers explain. “Since the topology optimiser cannot handle non-linear effects, the behaviour of the linear elastic anisotropic material together with the analysis of the small deflections was used in this stage. The goal of the optimisation was set to minimise the mass.”

The pylon was investigated first, and was then tested in load case II, according to an ISO standard. The test results were compared with the FEM simulations. The second object investigated was the support. FEM analyses and the optimization of two different designs were carried out: topology optimisation for the vertical and horizontal printing directions of a support with a wall thickness of 7 mm, and shape optimisation of the wall and base thickness of the support printed vertically, based on the existing geometry.

The pylons were horizontally and vertically 3D printed and tested in load case II, combining compression with the bending and twisting of each part. The test results were compared with the FEM simulations, and the two corresponded well. The supports were then tested and the results compared to the FEM simulations.

“It was shown that the Material Model gave a good prediction of the location of a failure and it even yielded reasonable estimates of the loads at failure when tested, according to ISO Standards. Hence, an FEM simulation can be a useful tool, when it comes to the optimal design of 3D printed objects and in predicting how they perform mechanically,” the researchers conclude. “Nevertheless, it needs to be considered that there may be large variations among 3D printed pieces, including dog bones, from which the mechanical properties were obtained or derived. The variations in the material properties (inputs to FEM simulation), e.g. Young’s modulus, yield limit and tensile strength etc., could possibly make an FEM simulation less reliable. Therefore, it is essential to have better control of the 3D printing process, which leads to reduced porosity and a variation in the 3D printed objects, in order for an FEM simulation of 3D printed objects to be reliable.”

Authors of the paper include Anders Linberg, Johan Alfthan, Henrik Pettersson, Göran Flodberg and Li Yang.

Black Panther and 3D Printing: PepsiCo Reveals Details About This Year’s Promotional Campaign

Marvel’s Black Panther was a huge hit earlier this year, and 3D printing played a starring role through the costume design. In addition, PepsiCo took advantage of the technology to have a limited edition series of Black Panther cans created, as seen at RAPID + TCT in May. Now the company has released more details on the process that went into making the cans, which featured a 3D printed mask created by Protolabs.

The special cans, which featured the movie’s main characters, were part of a promotional kit that also contained a Samsung tablet, comic books, behind the scenes photos, a light-up carton with smart LEDs, and, of course, the 3D printed Black Panther mask that fit onto the can.

“Much of this kit was inspired by the costumes and characters from the movie,” said Andrew Phinney, R&D packaging engineer at PepsiCo. “This was an exciting opportunity for us to incorporate new technologies to develop unique textures, graphics, dimensional elements, and lighting to bring the kit to life.”

Phinney led the mask’s technical development, and he and his team were faced with the challenge of producing a complex shape economically at a low volume, since they were only going to be making 250 of the promotional kits.

“Given the detailed features on the mask and the relatively low volumes of parts, we knew early on that 3D printing was going to be the most suitable manufacturing process for this project,” Phinney said. “The volumes were not high enough to justify investing in an injection molding tool and we liked the design freedom that 3D printing provides.”

For early stage prototypes, in-house FDM 3D printers were used to alter the design of the original mask so that it aligned with the design on the can and fit securely on it. The team then began considering what 3D printing technique to use for later prototypes and ultimately production. They decided to try out CLIP, SLS and Multi Jet Fusion technologies, and eventually settled on Multi Jet Fusion thanks to its low cost, high resolution, and excellent surface finish.

“When we received the Multi Jet Fusion part it was clear that this technology was going to meet the cosmetic requirements we outlined at the beginning of the design process,” said Phinney. “Not only did the part look great, but it was also the most affordable process among the final three technologies we considered. Since the can was meant to be a collector’s item, we wanted a part that could last 10 to 20 years. While other processes like SLA and PolyJet have high resolution, there was no guarantee that they would hold the deep black color and be able to last for several years.”

The final parts were 3D printed by Protolabs and put through a series of compression, vibration and drop tests, which they passed, remaining securely on the can. Just before the Black Panther premiere, the promotional kit was finished and sent out to hundreds of online influences and others involved with the movie. According to Phinney, it took less than six months to conceptualize, engineer and produce the kit.

“We needed a supplier that could meet our deadlines and Protolabs provided us with quality 3D-printed parts on time throughout the project,” said Phinney. “The success of the Black Panther mask not only demonstrates Protolabs’ capabilities, but the potential of 3D printing to advance packaging design.”

Interview with Hugo Fromont of Sharables Site Cults3D

3D Printables sites is one of the most competitive areas of the 3D printing industry. While Thingiverse still reigns supreme there are dozens of sites competing with each other nipping at Thingiverse’s heels. One of the larger ones is Cults3D, Cults3D from the beginning tried to make money by offering files for sale and subscriptions and grew through the tireless efforts of Hugo and his team. Cults was founded in 2014 Hugo Fromont, Pierre Ayroles and Sunny Ripert. While Ultimaker owns YouMagine and Pinshape is owned by Formlabs Cults3D is independent. Can the young company survive and prosper in the hyper-competitive sharables market? We interviewed Hugo Fromont to find out more about Cults.

The Cults Team (L-R): Sunny Ripert, Pierre Ayroles and Hugo Fromont

How did Cults3D get started?

“We created the platform at the end of 2014 and officially launched our start-up Cults in 2015. What gave us the idea to create Cults, was the fact that we bought a 3D printer to test and we wanted to create our own objects, but none of us were familiar with 3D software. We are true noobs in 3D modeling. However, there are many talented people whose passion, even the job, is to model 3D objects; it is these individuals that we wanted to highlight. The world of 3D printing will always need creators who have a real vision of a designer, a soul of an artist. Without quality 3D STL file to print, there is no need for a 3D printer. Cults was born to pay tribute to all these 3D designers who have a crazy talent, our name comes from the patron saint of artists and sculptors St. Luc, read backwards it becomes Cults. We also find there the extension stl which refers to the formats of 3D printing files.”

What is the site now?

The site currently offers several services:

  • Sharing and Downloading of 3D Objects: 3D designers drop off their digital 3D printable models on the platform. They choose to share their creations for free or by paying.
  • Makes and the Community: Cults is also a digital community that brings together all fans of the 3D printing universe to interact with each other. The makers who downloaded the 3D files and printed them can then share the photos of their creations with their settings and their use of the object. Members can follow the activity of their favorite creators through the Cults feed.
  • On Demand Design: If manufacturers cannot find a 3D file on our platform, we can make it on demand. Simply complete the application form on our site.
  • Deals and Promotions: Our service is also synonymous with generosity. Thanks to the Promotions part everyone can find offers and promo codes to buy products related to 3D printing at the best price (filaments, 3D printers, accessories, etc.).
  • Challenges: We also regularly organize design competitions on specific themes to encourage and animate our community.
  • The Blog: Our visitors can get the latest news related to 3D printing but also discover our tips and tricks our focus on designers or innovations through our blog.

These are a few figures:

  • We now have more than 300,000 international member makers registered on our platform.
  • We welcome more than 700 new users every day and more than 5,000 new members every week.
  • The platform currently hosts 35,000 designs and a community of 3,500 designers.
  • Our platform is translated into 3 languages: English, French and Spanish.
  • We have more than 1.6 million downloads and 150,000 downloads per month.

What is your business model?

We have a mixed business model, based on commissions taken on the sale of 3D files (20% – without having to pay a subscription fee from designers to have the right to sell); on advertising; on affiliation/partnerships; on 3D modeling on demand and on the use of our white label API.

Are people really paying to download models? Do you think this will happen more in the future?

Yes, that is an undeniable fact. More and more people are buying 3D models and more and more designers are looking to monetize their work. Our system allows designers to finance part of their hobby since the beginning. 3D printing is still a cost, so making money by selling your 3D files on Cults allows creators to continue to create great projects.

Some designs take weeks or even months of work and testing before publishing their 3D models that are perfectly optimized for 3D printing. Only designers own their designs. Quality models are able to sell their work. To show you, we have identified a Top 100 of the best 3D designers ranked here by number of sales.

How will you evolve in the future? 

We will focus on continuing our growth and listening more and more to our community. We would like to further improve our platform to make DIYers and designers feel more comfortable. There are still many features we need to create to optimize the download experience. But as we are a small team of 3 people, we often lack time but we never lose our energy and enthusiasm!

Where do you see yourselves in five years? 

In 5 years, we see ourselves becoming the reference platform for downloading 3D printable objects, whether you are a private individual or a professional. Currently, Cults is the first independent platform on this specialized market. Our main competitors belong to large groups (Thingiverse = Makerbot, Myminifactory = iMakr, Pinshape = Formlabs, Youmagine = Ultimaker…).

Why should I pick cults?

If you are a designer, you can be sure that we will do our best to promote your work. We use full potential of our other channels like social media and emailing to touch as many makers as possible. We consider ourselves to be artists’ agents. As we are independent, your work will be respected and will not be used as a pre-sales service to promote the group’s 3D printers. Cults is also a way to get compensation for your 3D modeling work. On the maker side, you will find many exclusive quality designs, 100% printable in 3D. Having a quality 3D file avoids failed prints and therefore wastes of time (and money in consumables / electricity). We are very close to our customers and designers. All requests are processed and we always try to answer within one day or even the next. Our responsiveness and proximity are among our values and strengths.

Who is your ideal customer?

Our ideal customer is a customer who frequently comes to re-purchase 3D models and who is attentive to new projects realized by his favorite designers that he follows on our platform. He is also someone who talks to designers to improve their work and show them what its prints look like. Via our option which allows you to post photos of your 3D printed creation, there is a real virtuous circle that is created and a sense of belonging to a community.

What kinds of things are being made on Cults3D?

“We are more oriented towards objects for the home (lamps, furniture, decoration), small useful inventions such as lifehacking / tools or even sculptures and objects from fan art. You can view our best STL files collections to see objects classified by themes.”

With several of the top sharables sites in the hands of OEMs will it be logical for Cults3D to partner with one? or be acquired by one?

It would not be logical for us and it is not really our dynamic right now. We are makers and individuals, not industrialists or traders who are absolutely looking for profit. We want to remain on a human scale and above all close and responsive to our community. If a brand or service in the 3D printing sector contacts us for a possible partnership or takeover, it must be done in accordance with our values and our independence, we will always be on the designer’s side. If we consider it positive for Cults and our members, we can consider it, but otherwise, it is out of the question!

 

What are some desktop 3D printing trends you’re seeing now?

We can see the arrival of colors and also of double extrusion. 3D printing speeds are also being improved, which is a major challenge. There is also the arrival of SLA printers on the 3D desktop printer market. What is also interesting to see is all these new materials that can be 3D printed with personal printers: carbon, wood, fluorescent filaments, etc.

Right now a lot of people are saying that desktop 3D printing is dead? 

People often compare personal 3D printing with industrial/professional 3D printing where houses, organs, aircraft parts etc. can be made. Obviously, these are not the same amounts of money at stake and growth is not the same. But it is not dead at all, quite the contrary. We are welcoming more and more makers to Cults, the price of 3D desktop printers has also dropped significantly, so many people can try 3D printing at low cost. There is also a trend towards multi-equipment. Maybe there will not be a 3D printer in every home one day, but there will be many in do-it-yourselfers’ garages, like drills, jigsaws, hammers, etc.!

Who will be your future users?

We also wish to address companies and professionals who need to share safely 3D printable models with their various circles: internal, customers, service providers. We also want to become a reference place to consult for any 3D printer owner who needs useful and creative objects.
