The conversation went something like:
If you wanted to build an interactive art object what would it be like?
It would grab peoples attention from far away.
It would make people smile.
It would make people feel good about themselves.
It should take people on an emotion journey. In other words, make them feel good and then take that away.
Hmmm… What is something kind of universal that almost everyone likes to do? PUSH BUTTONS!
One of the oldest industrial exhibitions in Germany opened its doors to the public in Berlin on Friday as IFA 2018 began. Many additive manufacturing companies choose to showcase their latest products at this annual show – last year, for instance, Taiwan-based desktop 3D printer manufacturer XYZprinting introduced its da Vinci Color 3D printer.
At this year’s show, the company will be introducing the consumer-oriented da Vinci Color mini, in addition to exhibiting its award-winning da Vinci Color AiO, which was officially introduced at CES 2018. But on the first day of IFA 2018, the company also announced the official UK launch of the AiO, which it calls the first voice-controlled, full-color FFF 3D printer in the world with an inbuilt engraver and 3D scanner.
“This latest innovation is a significant step forward for 3D printing, particularly for desktop users. Being able to control your printer with something as intuitive as simply speaking will open up 3D printing to a wider range of people,” said XYZprinting CEO Simon Shen.
“The AiO is aimed at those that have not used 3D printing a lot previously or not used it at all. Being able to tell the printer what you want it to do will make it simple to navigate, as well as letting you search from the XYZ 3D gallery. This means that if you would like to find a 3D model of a vase, you would just say ‘search for a vase for me’ and the 3D gallery would bring up all vases on the gallery to choose from.
“The added features of the printer, the scanner and the engraver, make the AiO the most complete desktop 3D printing unit ever developed, giving entrepreneurs and designers the chance to bring their ideas to life.”
The AiO, which stands for All in One, has certainly grown since its first iteration two years ago as the da Vinci 1.0 Pro 3-in-1. The handy desktop 3D printer, scanner, and engraver will give designers, educators, engineers, and entrepreneurs alike the ability to use intuitive voice commands to easily control the system. In addition to 3D scanning objects, users can 3D print full-color objects through the use of simple voice activation, and can later engrave those same prints as well.
Actually, this last may not be true – the da Vinci 1.0 Pro 3-in-1 was only able to engrave objects made out of cardboard, leather, and wood, which the da Vinci Color AiO can’t actually 3D print. But, the old version had the laser engraver as an optional module, while the updated 3D printer features an inbuilt engraver, so maybe things have changed?
Regardless, the da Vinci Color AiO makes it easy for users to replicate and personalize designs with the built-in 3D scanner and engraver. It also features full-color 3D printing – the company’s 3D Color Jet technology mixes and sprays CYMK color droplets onto white PLA filament deposit layer by layer, “achieving full-colour spectrum accuracy and precision,” according to XYZprinting.
The desktop 3D printer also features a new EZ-removable print bed, with a 20 x 20 x 15 cm build volume that helps prints adhere to the bed while still being easy to remove from it. The print bed is also auto-leveling, so you never have to worry about the accuracy of your prints.
The coolest thing about the da Vinci Color AiO, at least in my opinion, is its voice control. My husband and I just purchased an Amazon Fire Stick, and I’m still tickled at my newfound ability to hold down the microphone button and say things like, “Alexa, go to Netflix” and “Alexa, add cereal to the grocery list.” Imagine how much cooler this feature is with a 3D printer: the da Vinci Color AiO allows users to calibrate the 3D printer, prep their print jobs, pause 3D printing, conduct maintenance on the system, and receive status updates on their prints, all with just their voice. This makes me feel like we’re one step closer to asking the computers on our spaceships to locate Commander Data…
XYZprinting is exhibiting at IFA 2018 through Wednesday, September 5th, in Hall 12, Stand 107 of the Berlin Exhibition Grounds at Messe Berlin. At the event, the company will be launching the da Vinci Color mini, a compact version of its original full-color 3D printer that’s designed for use at home and in schools and offices. The accessible mini 3D printer features an intuitive user experience, thanks to its 5″ color LCD display screen, and will retail for the recommended price of £1,599 beginning in December.
The da Vinci Color AiO will be available for purchase starting in September, for the recommended price of £2,699, through the company’s network of partner resellers.

Awesome advances in eye implants. Via Digital Trends:
Now, engineers from the University of Minnesota have made another significant step in the development of bionic eyes. In a paper published this week in the journal Advanced Materials, the researchers describe how they 3D printed a prototype for a synthetic eyeball, equipped with photodetectors that allow the device to pick up light. The prototype could help usher in more advanced devices for visually impaired people.
“Here we demonstrate a fully 3D-printed hemispherical photodetector array that can sensitively detect images with a wide field-of-view,” Ruitao Su, a research assistant at the University of Minnesota who worked on the project, told Digital Trends. “The high efficiency of the photodetectors and the ability to readily customize the size and layout of the design render this approach … promising for the creation of bionic eyes.”
To make the device, the researchers began with a hemispherical glass cone, which they used as a sort of canvass to 3D print an array of photodetectors. Silver nanoparticles were used as conductive interconnections, and a couple layers of semiconductive components helped convert light into electricity. Finally, liquid metal was used to print cathodes on top. The whole process, which took about an hour, is pretty complicated but still generates a relatively primitive prototype.
Last year, a project was announced: the NextGenAM collaborative project, dedicated to developing and implementing next generation industrial additive manufacturing technology. The partners involved include Premium AEROTEC, EOS, and Daimler. A goal of the project was to develop the basis of a future system for series production using 3D printing technologies. The project team has been working on assessing the additive manufacturing process to see what kind of potential it holds for automation, and now the first pilot plant has been launched at Premium AEROTEC’s technology center in Varel.
Aluminum is the material in focus here; the project aims to create a production cell that is capable of manufacturing aluminum parts for the automotive and aerospace industries in particular. Titanium has been the main material used for additive manufacturing in aerospace thus far, but one of the project’s goals is to also qualify aluminum for use in the industry. The facility contains several machines for additive manufacturing, post-processing, and quality assurance. All steps are fully automated and integrated, eliminating manual work altogether.
“The integration of the AM process in an automated production line is an important milestone for the broad application of our technology in series production scenarios,” said Dr. Tobias Abeln, CEO of Premium AEROTEC.
Central to the plant’s operations is the EOS M 400-4 four-laser system, which is being used in combination with the EOS Shared-Modules concept. This means that the M 400-4 is equipped with a powder station and is connected to a standalone setup and unpacking station. Therefore, filling and emptying the system of metal powder, setting it up to prepare for a new build job, and unpacking the finished components can be carried out independently of and parallel to the 3D printing process, greatly increasing productivity.
Downstream post-processing has also been automated. A robot takes the build platform with the parts for the setup system and places it in a furnace for subsequent heat treatment. It then removes the platform again and takes it to a three-dimensional optical measurement system for quality assurance. The build platform is then conveyed to a saw, which separates the parts from the platform.
“In this project we have already succeeded in significantly reducing the production cost per part, thus creating an economic perspective for large-scale digital 3D printing factories,” said Dr. Thomas Ehm, CEO of Premium AEROTEC.
Over the next several months, the pilot process chain will be further tested and parts of the facility will be audited. Production data will be collected and analyzed with the goal of collating precise data on process times, profitability, and cost optimization.
“3D printing is well on the way to establishing itself in the automotive sector as an additional manufacturing method with great versatility,” said Jasmin Eichler, Head of Research Future Technologies at Daimler. “With this collaborative pre-development project, we are taking a significant step towards achieving cost-effectiveness in metal 3D printing throughout the process chain. The project lays the cornerstone for the future realization of larger quantities in the automotive series production process – with the same reliability, functionality, longevity, and economy as for components from conventional production.”

Welcome to this month’s last edition of 3D Printing News Briefs! Today, in honor a new month starting tomorrow, we’re starting with stories about everything new. BEEVERYCREATIVE will soon launch a new 3D printer kit, while Fast Radius is opening a new headquarters and Thor3D welcomes a new CEO. Verashape is introducing the latest version of its SOFTSHAPER software, and Link3D launched a new additive manufacturing scheduling solution. Moving on from new things, Midwest Engineered Systems, an official KUKA partner, will be displaying its technology at IMTS 2018, and a company used its innovative laser cladding technology to restore a CNC spindle.
BEEVERYCREATIVE’s New 3D Printer Kit
Portuguese 3D printer manufacturer BEEVERYCREATIVE is getting ready to launch a new 3D printer DIY kit, and will present it publicly for the first time at the upcoming TCT Show 2018 in Birmingham. This is a big deal for the company, as it hasn’t introduced had a product launch for a new 3D printer since 2015; employees have been very busy working on the MELT project for the European Space Agency for the last two years, and are more than ready to introduce the new B2X300 3D printer kit.
BEEVERYCREATIVE conduct multiple studies before the launch, including market research on 3D printer user patterns and collecting quantitative and qualitative information from users about its helloBEEprusa 3D printer kits. The B2X300 is named for the company’s brand (B), its two extruders (2X), and its 300 x 200 x 300 mm print area (300), and was delivered to several beta testers this spring for testing and feedback. Aside from its build area, number of extruders, and the fact that it features auto bed leveling and trinamic drivers, we don’t know much about the 3D printer kit yet. But all will be revealed by mid-September.
Fast Radius Opening New Headquarters and AM Factory
3D printing solutions provider Fast Radius is scaling up its manufacturing footprint, and recently opened its new headquarters in Chicago’s West Loop, which features an advanced, industrial-grade 3D printing facility. This facility is home to extensive HP MultiJet Fusion technology, as well as what the company calls the largest Carbon production facility in the Western Hemisphere. This was a well-thought out location: the building of the Chicago-based Digital Manufacturing and Design Innovation Institute (DMDII) was where the company’s new CEO Lou Rassey first collaborated with several other Fast Radius executives, including Chief Scientist Bill King, PhD, Chief Product Officer John Nanry, and Enterprise Solutions Leader John Ramirez. The rest of the company’s executive team includes Vice President of Sales and Marketing Brian Simms and COO Pat McCusker.
Rassey said, “It was important to the Fast Radius team that we were headquartered in Chicago, as we are passionate about being a part of the next great industrial manufacturing renaissance in this city, the Midwest, and ultimately, the world.
“Pat, John, Bill, John and Brian form the perfect core team to grow Fast Radius as we build out our technology platform and global footprint to bring manufacturing innovation to the world at scale.”
Thor3D Welcomes New CEO
This week, Moscow-headquartered 3D scanner manufacturer Thor3D announced that it has appointed its very first Chief Executive Officer. The new CEO, Anna Zevelyov, is a company co-founder and a 3D printing market veteran who had been serving as Thor3D’s Sales Director; her long-time lieutenant, Vadim Fomichev, will now be taking on this role. Under Zevelyov’s leadership, the company will be focusing on R&D, with plans to release at least one new 3D scanner each year.
“Some history…the company was, until now, ruled by committee. Although periodically, this “collective-wisdom” approach was beneficial, over time we realized that a strict hierarchy and one person at the helm is needed,” Zevelyov wrote in a statement. “The Board of Directors took 6 months to consider whether to nominate a CEO and if yes, who that might be. After much debate about how this could change the culture of the company, the decision was made this month. I was elected unanimously, which, naturally, boosts confidence, as I take on this new challenge.
“I am honored and optimistic. My first priority will be R&D (after all, Thor3D is, first and foremost, a technology company). My aim will be to significantly improve our current technology and to introduce a new 3D scanner at least once a year (expect to hear big news before the end of the year). Another priority will be organization of our intellectual property. I anticipate filing a number of international patents over the next year to formalize the innovative work that has been done in the company over the previous months.”
New SOFTSHAPER Software Version
Verashape, which manufactures the VSHAPER line of 3D printers, has just introduced the latest version of its SOFTSHAPER software. Thanks to a license granted to the company by Siemens PLM Software last year, SOFTSHAPER 2019 is based on Parasolid Communicator. There are many improvements and new features in this latest version of SOFTSHAPER, including a technological process tree, detailed reports, and the ability to group layers and print manually adjusted supports.
“A huge simplification that SOFTSHAPER 2019 provides us with is the ability to print supports with higher density,” explained Seweryn Nitek, a Software Engineer at Verashape. “The density is higher only in the area of contact with the model. In other areas, the density of supports is selected in relation to the required stiffness. This saves time for printing supports, which are then removed by the user.”
Midwest Engineered Systems Displaying KUKA Technology at IMTS 2018
Two years ago at IMTS 2016 in Chicago, KUKA Robotics showcased how its robots integrate with 3D technology thanks to partnerships with companies like Midwest Engineered Systems (MWES), a leader in complex systems integration. MWES provides services such as robotic welding, machine tending, material handling, and automated production lines, but has become well-known in the last few years for its work in laser wire additive manufacturing. This technology is able to create very large parts, while also saving up to 90% of the material normally machined away.
“We’ve actually come up with a way way to print with metal using wire. Really what that does is allows you to print larger parts and it allows you to print them faster,” said Scott Woida, the President of MWES, in a video.
The company’s additive manufacturing system uses the hot wire process to preheat wire before it enters the molten pool. At the upcoming IMTS 2018, you can check out the MWES technology for yourself at KUKA’s Booth N-236200.
Restoring CNC Spindle with Laser Cladding
A company called Synergy Additive Manufacturing LLC (SAM), which claims to be one of the only turnkey jobshops to offer metalworking services like final machining, heat treating, metal forming, 3D CAD design, and 3D printing, also developed a laser cladding process is a more cost-effective alternative to hard chrome coatings. The company offers a 24 hour turnaround on the dimensional restoration of rotating components, like motor shafts and CNC spindles, using this technology.
In a new video, SAM demonstrated how its laser cladding method can be used to restore a CNC spindle. The technology offers a good metallurgical bond, and there is no chipping away or peeling once the restoration is complete. You can see this for yourself in the video below:

Laser powder bed fusion 3D printing requires a great deal of effort to make sure that quality parts are being produced – and there are a lot of things that can go wrong with metal prints, such as porosity and residual stress, which causes distortion and part failure. Therefore, it is important to optimize the machine parameters as much as possible. In a paper entitled “3-Dimensional heat transfer modeling for laser powder-bed fusion additive manufacturing with volumetric heat sources based on varied thermal conductivity and absorptivity,” eight 3D heat sources used for simulating laser powder bed fusion are compared, and new equations for varied thermal conductivity and laser absorptivity are proposed.
“The physical phenomena associated in a melt pool are highly complicated, mainly controlled by mass and heat transfer,” the researchers explain. “The heating and cooling rates are extremely high due to the fast-moving laser irradiation on the powder particles. In addition, the dynamic melt pool development beneath the powder-bed, phase change dynamics from liquid to vapor and plasma, and powder particles drawn by high-speed metal vapor flux and capillary effects exist in the melt pool. Therefore, fine-scale numerical models, which included several details, such as laser-ray tracing in randomly distributed particles and thermal fluid dynamics, have been built in order to simulate several complex melt pool behaviors. However, the computational cost for such simulations is extremely high.”
Therefore, the researchers propose effective simulation models with certain approximations and assumptions to predict the dimensions of melt pools, in order to reduce the computational time.
Experiments were carried out on an EOS M 290 machine. A 3D heat transfer finite element model for laser powder bed fusion was developed for accurately predicting melt pool dimensions and surface features.
“Based on the literature review, eight heat source models are used for the numerical modeling of LPBF and can be categorized as 1) geometrically modified group (GMG); and, 2) absorptivity profile group (APG),” the researchers state. “Experiments were carried out to validate the simulation results. All the eight heat source models lead to over 40% shallower melt pools compared with the experiments.”
To improve the model performance, a mathematical model with varied anisotropically enhanced thermal conductivity and varied absorptivity was proposed and applied to the heat transfer simulation with the exponentially decaying heat source.
The researchers came to two main conclusions:
“The expressions of varied anisotropically enhanced thermal conductivity and varied absorptivity were linear algebraic equations,” they state. “Good agreement between the simulation and the experimental results was derived. The averaged error of melt pool width and depth are 2.9% and 7.3%, respectively.
“The proposed heat transfer model has been further validated by the surface features, track stability and ripple angle. For the track stability, the predicted results are in good agreement with the experimental results. In addition, the simulated ripple angles are within the range of experimental results.”
They also concluded that the heat source expressions can be linear while causing the simulation results to be in better agreement with both experimental melt pool dimensions and track surface morphology.
Authors of the paper include Zhidong Zhang, Yuze Huang, Adhitan Rani Kasinathan, Shahriar Imani Shahabad, Usman Ali, Yahya Mahmoodkhani, and Ehsan Toyserkani.

SLA prints are oftentimes quite weak in comparison to various other additive manufacturing methods. This perception of weakness has often help them back from having applications in industrial environments. The mechanical properties of SLA prints can, however, be improved with certain methods, as a new study proves. Researchers at China’s Zhejiang University have shown that cross-linking can […]
