Wikifactory’s Docubot Challenge Creates a Hardware Solution for Documentation

International startup Wikifactory, established in Hong Kong last June, is a social platform for collaborative product development. Co-founded by four makers and counting 3DPrint.com Editor-in-Chief Joris Peels until recently as a member of its advisory board, Wikifactory also has locations in Madrid and Shenzhen, and is dedicated to makers and DIY projects. It’s an all-in-one workspace designed for open source communities to help connect product developers to useful tools, such as 3D printing.

Recently, the platform launched the Docubot Challenge to help inaugurate the first Distributed Hardware Hackathon in the world. The global open source community was charged with finding a hardware solution for an issue that every maker faces – documentation.

This is a very prevalent issue in the maker community in terms of open knowledge for the purposes of digital fabrication. Documentation makes it possible for community members to gain the necessary knowledge and skills to further contribute to an ever-growing base of information. But just because it’s useful doesn’t mean it’s easy – while documenting fabrication methods may be a necessary evil, it can be a painstaking and tedious process that can slip through the cracks if you’re not meticulous about updating your work.

“Every product developer faces the task of having to document their work, but it’s a painful process. When your hands are full with what you are doing, it’s hard to take a step back and jot down the steps. That’s why documentation is often written after the process has already been completed, so there will always be missing photos or information,” the challenge states.

“We should strive to make the process of documentation easier, because Documentation in itself is an amazing thing. As a resource, it helps a broader community learn the skills and acquire the knowledge to contribute to a growing open source knowledge base.”

The Wikifactory team really wanted to turn the first edition of its Docubot Challenge into a distributed event; it is, after all, tagged as being “designed for makers, by makers.” Due to support from makerspaces around the world – specifically Pumping Station One in Chicago, Makerspace Madrid, and TroubleMaker in Shenzhen, China – this hope became a reality. Wikifactory is a great tool when organizing maker community events like workshops and hackathons, as it makes it simple to bring teams together online so they can contribute before, and even after, the event.

The goal of the challenge was to, according to WikiFactory, “accelerate a solution to a common problem faced by product developers” by collaboratively building a real-time documentation assistant that will take photos and videos on command, and could even convert speech to text. As someone who spends plenty of time transcribing recorded interviews, I want to know when this documentation assistant will be commercially available!

“With a hardware solution, doing documentation can be made into a more interactive, assisted process which can help accelerate engagement and collaboration in open source design and hardware,” the challenge stated.

The Docubot Challenge was originally instigated by Wikifactory members Gianluca Pugliese and Kevin Cheng. The participants were connected through Wikifactory to host project events in their own cities, engage with other teams around the world, and accept feedback and advice from other problem solvers. While it was definitely a learning experience, Docubot is now officially an open source hardware initiative, and great progress has already been made.


“The Shenzhen Team developed an app that converts speech to text, the Madrid Team created a fun game that helps makers beat laziness and get documenting, and the Chicago Team created a button that signals a phone to start recording voice messages as well as pictures,” Wikifactory wrote.

The worldwide maker community is invited to get involved and contribute to the Docubot initiative. Whether you’re working on design ideas, developing the app and OS, or the hardware integration, the collaborative project needs your help in further extending the ideas by the team members who originally started it.

“With interactive and intercity sessions, participants will get to build relationships with creative problem solvers from around the world. It is an opportunity to apply skills in digital fabrication machines like 3D printing, hardware, electronics, programming and robotics for a relevant cause.”

Sciaky Joins R&D Initiative to Combine Traditional Metallurgy with Wirefed Metal 3D Printing Techniques

Metal 3D printing solutions provider Sciaky, Inc., well known for its extremely popular Electron Beam Additive Manufacturing (EBAM) process, just announced that it has entered into a research and development initiative with metallurgist expert Aubert & Duval – a subsidiary of the Eramet group’s Alloys division – and Airbus, one of its previous 3D printing partners. The ambitious initiative, also called the Metallic Advanced Materials for Aeronautics (MAMA) project, is being driven by the Saint Exupéry Institute for Research in Technology (IRT), and the academic partner for the project is the Production Engineering laboratory of the National School of Engineering in Tarbes, France.

“Sciaky is proud to work with the Saint Exupéry IRT, Aubert & Duval and Airbus on this exciting project. Industrial metal additive manufacturing technology continues to break new ground every day, and Sciaky is committed to keeping EBAM at the forefront of this movement,” said Scott Phillips, the President and CEO of Sciaky, Inc., a subsidiary of Phillips Service Industries, Inc. (PSI).

In terms of work envelope, Sciaky’s exclusive EBAM technology is probably the most widely scalable metal AM solution in the industry. It’s the only industrial metal 3D printing process that has approved applications for air, land, sea, and space, with gross deposition rates up to 11.34 kg of metal an hour, and is able to manufacture parts from 203 mm to 5.79 meters in length. Rather than just melting the outer layer of the metal powder, the EBAM process completely liquefies the metal wire feed.

The fast, cost-effective EBAM process offers a wide range of material options, including titanium, for large-scale metal applications, and uses its adaptive IRISS (Interlayer Real-time Imaging and Sensing System) to combine quality and control, as the patented system can sense, and digitally self-adjust, metal deposition with repeatability and precision. It is mainly due to the IRISS system that the Chicago-based company’s EBAM 3D printing process is so good at delivering, as the company puts it, “consistent part geometry, mechanical properties, microstructure, and metal chemistry, from the first part to the last.”

The goal of its combined MAMA project with Airbus and Aubert & Duval is to combine traditional metallurgy (high-power closed die forging) with new wirefed metal 3D printing techniques, such as Sciaky’s EBAM process, in order to come up with new processes for manufacturing titanium alloys that can be used to make aircraft parts. Based on the caliber of its partners, Sciaky made a good decision in joining the R&D initiative – Airbus is a 3D printing pioneer in the aerospace industry, and Aubert & Duval creates and develops advanced metallurgical solutions for projects in demanding industries, such as nuclear, medical, energy, defense, and aeronautics.

The project’s first phase has global funding in the amount of €4.2 million. 50% of this funding is supported by the French State as part of its “Investing in the Future” program (Programme Investissement d’Avenir, or PIA), while the other half is funded by industrial partners of the initiative.

The researchers at Oak Ridge National Laboratory (ORNL) in Tennessee have spent a lot of time working with unique 3D printing materials, such as polyester, lignin, and nanocellulose, which is a bio-derived nanomaterial. Now, a new research collaboration between ORNL and the University of Maine’s Advanced Structures and Composites Center aims to increase efforts to use wood products as 3D printing materials. Together, the team will work with the forest products industry to create new bio-based 3D printing materials that can be used to make products like building components, boats and boat hull molds, wind blades, and shelters.

The large-scale initiative was announced this week in Washington, DC. Leaders from the university and ORNL, as well as the DoE‘s assistant secretary for energy efficiency and renewable energy Daniel Simmons, the founding executive director of the Advanced Structures and Composites Center Habib Dagher, and US Sens. Susan Collins, Lamar Alexander, and Angus King were all on hand for the announcement, which also stated that UMaine and ORNL had received $20 million in federal funding for the program from the DOE’s Advanced Manufacturing Office.

“While Oak Ridge is a global leader in additive manufacturing, the University of Maine is an expert in bio-based composites. By working together, they will strengthen environmentally responsible advanced manufacturing in America as well as helping the forest industry in the state of Maine,” Senator Collins said.

Sens. Collins and King requested federal help to save the declining forest products industry in Maine back in 2016, after several paper mills in the state closed their doors. This led to the founding of the Economic Development Assessment Team (EDAT) to work across agencies in order to come up with economic development strategies for the rural communities in Maine that were suffering from the mill closures. This team resulted in the ongoing partnership between UMaine and ORNL.

“Using Maine forest products for 3D printing is a great way to create new jobs in Maine and a good reminder that national laboratories are our secret weapons in helping the United States stay competitive in the rapidly changing world economy. The partnership between the University of Maine and the Oak Ridge National Laboratory is a model for how science and technology can help Americans prosper in the new economy,” said Senator Alexander.

This October, ORNL’s BAAM 3D printer will be installed at UMaine, which is actually considered a world leader in cellulose nano fiber (CNF) technology. UMaine students can also visit ORNL’s Manufacturing Demonstration Facility (MDF), while staff from the laboratory can in turn learn about cellulose fiber and composites at UMaine’s composites center.

One of the printer’s first tasks will be to fabricate a boat mold out of a wood-based plastic, though the team hopes to apply the technology to many large-scale manufacturing applications.

Dagher explained, “The material is nanocellulose, basically a tree ground up to its nano structure. These materials have properties similar to metals. We are taking those and putting them in bioplastics so we can make very strong plastics that we can make almost anything with.”

The team will then add the nanocellulose to PLA.

“The University of Maine is doing cutting-edge research related to bio-feedstocks and the application of advanced manufacturing in regional industries,” said Thomas Zacharia, the director of ORNL. “We are thrilled at this opportunity to expand our research base while providing UMaine with access to the leading national capabilities we have developed at ORNL’s Manufacturing Demonstration Facility.”

The overall goal for the initiative is to find new uses for wood-based products in an effort to reinvigorate Maine’s forest products industry, while also helping to make regional manufacturing stronger by connecting university–industry clusters with the MDF. The federal funding will be divided equally between both facilities.

“We will integrate 20 years of research in bio-based composites at UMaine and 3D printing at ORNL. It is an opportunity engine for our students, faculty, staff and manufacturing industry who will work side by side with researchers at our nation’s foremost research laboratory. Together, we will break down wood to its nanocellulose structure, combine it with bioplastics, and print with it at hundreds of pounds an hour,” said Dagher. “The research we will be conducting with ORNL will spur next-generation manufacturing technologies using recyclable, bio-based, cost-effective materials that will bolster our region’s economy.”

Scientists from UMaine and ORNL will be conducting research in multiple areas, such as multiscale modeling, CNF production, drying, functionalization, and compounding with thermoplastics, and sustainability life-cycle analysis.

CNF could actually rival the properties of steel, and by successfully adding it into plastics, the researchers could create a renewable feedstock for strong, recyclable, bio-derived material systems that might even be 3D printed at deposition rates of hundreds of pounds an hour. Additionally, using a material that’s 50% wood could help open new markets for the forest products industry.

UMaine will get world’s largest 3D printer and use wood-based plastic to make boat molds

US Marines Using LulzBot 3D Printers to Successfully Continue Their Mission

3D printing in the military isn’t just about fabricating weapons like grenades, missiles, and warheads. The US Marine Corps has embraced the technology with enthusiasm, using it to research and complete a wide variety of projects. These days, logistics in particular is a fairly complicated defense sector, and investing in 3D printing has allowed the Marines to learn how to travel lighter to missions, with more adaptability…par for the course for this branch of the military, which counts “Improvise, Adapt, and Overcome” as its unofficial motto.

The USMC’s Next Generation Logistics Innovation group (NexLog) was established in 2015 to advocate for the use of modern technologies, such as 3D printing, on the front lines. The initiative, led in part by Col. Howard Marotto and Captain Matthew Friedell, speeds up development and integration of these technologies within the Marine Corps, and gives the Marines a way to develop solutions to problems directly affecting them and their environment.

“We see it as being absolutely transformative. It’s not just about untethering yourself from the supply chain,” Marotto said. “It’s also about being able to rapidly innovate to the threat in the field.”

The Marine Corps is more than ready to use 3D printing in any way they can, and LulzBot 3D printers from Aleph Objects are now being used by Marines in their important mission: to help build and grow a more innovative culture.

When the US military first got wind of 3D printing, the technology originally provided the perfect solution to a long-time problem: a continuing shortage of available spare and replacement parts for equipment that was getting older, thus more difficult to maintain.

Marotto explained, “A lot of our older equipment in the Marine Corps, nobody wants to make those items or parts for. So we might have to become our own manufacturers on certain low-demand, obsolete type items because the industrial base won’t support us, because there’s no money in it.”

In one of the many ongoing efforts to use the technology to “Charlie Mike” (Continue Mission), the Marines have started to design and 3D print replacement handles for their Humvees on LulzBot 3D printers. The standard vehicle handles are extremely fragile – not good if you’re on the front lines and need to get up and moving quickly.

LulzBot 3D printers have been a good choice for the Marines, thanks in large part to the LulzBot MOARstruder Tool Head – a popular option for applications that require strong parts and rapid prototyping capabilities.

“I use a MOARstruder on the thing and it prints in an hour, and you can’t break that thing…that’s my favorite example of using a LulzBot and more specifically, the MOARstruder,” said Friedell.

Another application for 3D printing in the Marine Corps is providing solutions in expeditionary environments.

“It’s stuff like buckles that you don’t think would be very valuable, but they’re huge in an expeditionary environment,” Friedell said. “If your buckle breaks that’s holding your weapon, your life is gonna suck for the next 10 miles or 3 weeks until you can get a new plastic buckle. So having that ability is huge.”

A recent example is a small snowshoe clip, 3D printed using a strong, flexible resin, that the Marines developed at the Mountain Warfare Training Center (MWTC) in northern California. Marines are now extensively training in very cold environments, which can cause a slew of new problems for their important gear.

Friedell said, “We have a snowshoe in our inventory and Marines keep breaking small retaining clips. So we had Marines redesign them and we’re actually able to 3D print them and throw them on the snowshoes, and now we have snowshoes that don’t fall off our feet.”

The Marines were able to call on their trusty LulzBot 3D printers to come up with a fast, inexpensive solution to this particular problem.

“I’ve been a big proponent of LulzBot [3D Printers] because it’s just bulletproof, and that’s the reason we put it out there. We literally load them up in [watertight] cases, unbox them…. they level themselves, and they’re printing in five minutes. So the durability of them, the flexibility of them, is awesome,” Friedell said.

Because LulzBot 3D Printers are so reliable, durable, and easy to use, Marines stationed in difficult environments all around the globe can put them to work in tasks ranging from mission-critical to simply making everyday life more convenient.
