Researchers are developing methods to insert DNA-like info into 3D printed objects.
Researchers at ETH Zurich have now collaborated with an Israeli scientist to develop a means of storing extensive information in almost any object. “With this method, we can integrate 3-D-printing instructions into an object so that after decades, or even centuries, it will be possible to obtain those instructions directly from the object itself,” explains Robert Grass, Professor at the Department of Chemistry and Applied Biosciences.
As a use case, the researchers 3-D printed a rabbit out of plastic that contains the instructions (about 100 kilobytes’ worth of data) for printing the object. The researchers achieved this by adding tiny glass beads containing DNA to the plastic. “Just like real rabbits, our rabbit also carries its own blueprint,” Grass says.

Liz Clark, AKA BlitzCityDIY recently posted a remix of one of our Circuit Playground snap fit cases. Just in time for the holidays, this turns any Circuit Playground into a light-up tree topper. We printed it on our Creality CR-10S using Eryone Silky Gold PLA. A Circuit Playground Bluefruit works well here since we can change up the NeoPixel colors and animations. We wired up a JST slide switch adapter and used a 500mAh battery. The case has a built-in holder for the slide switch so it’s easy to turn it on/off. It also fits nicely on our Christmas tree! If you’d like to build your own, check it out on Thingiverse.
In the recently published ‘Developing Fall-Impact Protection Pad with 3D Mesh Curved Surface Structure Using 3D Printing Technology,’ authors Jung Hyun Park and Jeong Ran Lee once again prove our point that 3D printing is affecting nearly every industry today—and positively so.
Here, the researchers raised the concern of the ease in which the elderly are injured by falls, which are all too common. With their new concept for 3D printed fall-impact protection pads, seniors may not be able to prevent falls that usually occur due to balance issues with age, health conditions, dizziness due to medical treatments, failing eyesight and more, but they may be able to survive them much better.
Park and Lee, both hailing from Pusan National University in Korea, present a design for curved protective pads that could be printed directly from scans of patients, allowing for individually-specific treatment—one of the greatest benefits of 3D printing in the medical realm today. And assistance is obviously much needed in this area as reports from Korea show that increasing numbers of elderly Koreans are taking such serious falls that they must be hospitalized; in fact, some remain in the hospital for over two weeks—often due to broken hips.
“It is becoming increasingly important to prevent the elderly from falling. Wearing hip protectors can prevent falls or reduce the damage caused by falling,” explain the researchers. “However, existing hip protectors are not suitable for use with daily clothes; they are not widely utilized because of aesthetic limitations. Furthermore, they are not comfortable. Therefore, it is necessary to develop an optimized impact protector with due consideration for body characteristics and motion.”
“Additionally, it is necessary to improve the wearing satisfaction by designing the impact protector in a form that is suited to the shape and motion of the human body while maintaining its protection performance.”
The 3D modeling process included creating a baseline for body scan data, making an outline, and then using a pad outline along the patient’s body—making a curve to mimic the human body. Afterward, they created a hexagonal mesh structure, with the pad completed by transforming the mesh structure—according to the curves of the body.
The 3D printed pads were fabricated via FDM 3D printing using a Cubicon Single 3D printer, chosen due to its capabilities for using more flexible materials; thus, a flexible TPU was used for creating the padded materials.
The researchers were forced to divide printing of the pads due to size:
“The radial split method for dividing pieces into three by 120° from the center point of the pad, and the elliptical split method for dividing pieces into four according to the sideline and curved surface were used,” explained the researchers.
Once supports were removed, the parts were stitched together. Overall, the parts proved to be ‘structurally flexible,’ and the modeling proved to be excellent for creating the necessary protection.
“Through several iterative experiments, we developed a reasonable and delicate modeling method that yielded results which are applicable to research on clothing and other fields,” stated the researchers. “Existing 3D printing technology has been deployed to produce very hard products; however, in this study, the printing conditions were finely set, in consideration of the complex characteristics of flexible filament materials. Finally, we believe that our findings foreground the possibility of using 3D printing technology to print complex and elaborate shapes in the field of functional clothing.”

The commercial vehicles segment of Mercedes-Benz parent company Daimler AG has fully integrated 3D printing into the development process and series production workflow for several of its divisions, such as Daimler Trucks North America and Daimler Trucks & Buses; in fact, the latter already features 3D printed parts built into the interior of its buses.
According to its website, Daimler Buses is the “leader in its most important traditional core markets,” and is now expanding its use of 3D printing for bus parts, collaborating with SLS leader Sintratec for the initiative.
“With 3D printing the Daimler bus division can respond quickly, flexibly, economically and environmentally friendly to urgent customer needs,” Ralf Anderhofstadt, the Head of the Center of Competence Additive Manufacturing, Daimler Buses, stated in a Sintratec press release. “The advantages of additive technologies, especially with regards to spare parts, are evident.”
Rather than utilizing external service providers, this coming year Daimler Buses will be setting up its own personal service bases, with the 3D production support of Sintratec. These 3D printing centers, to be used for the fabrication of both individualized components and spare parts, are a smart idea in terms of economics and logistics – it will only take a few days, rather than several months, to manufacture and deliver a 3D printed part, which produces much less waste and costs far less money.
Swiss high-tech company Sintratec develops and manufactures precise SLS 3D printers for professional purposes. The company’s materials are temperature-resistant and resilient, and its technology allows customers plenty of design freedom in creating complex objects for 3D printing.
Sintratec’s first desktop SLS system was successfully crowdfunded on the Indiegogo platform back in 2014, and the company has since moved on to bigger printers, introducing its modular, industrial Sintratec S2 system at last year’s formnext. This affordable, end-to-end SLS solution is perfect for education and training, in addition to fabricating prototype parts and small and medium-sized series.
The smart S2 has a modular construction, with the build chamber inside the Material Core Unit, but easily removable from the Laser Sintering Station. The system also includes an integrated powder mixing function, a Blasting Station and Polishing Station, and an additional Material Core Unit for convenient powder handling.
Now, Sintratec is excited to help contribute to the bus industry’s continuing digitalization. Recently, the S2 system was delivered to the Neu-Ulm, Germany production site of EvoBus GmbH, Daimler AG’s largest European subsidiary. The 3D printer will be used at this location to, as the release states,” convey technological know-how” at Daimler Buses’ new 3D printing centers, and to help advance the development, and optimization, of 3D printing materials.
“Special thanks to the entire EvoBus GmbH team for letting Sintratec participate in this outstanding event and present our vision of the digital factory as well as our Sintratec S2 system,” said Gabor Koppanyi, Sintratec’s Head of Marketing & Sales. “We are very proud of this partnership and are looking forward to more fantastic projects where we can shape the future together.”
