Mantle’s three collaborations based on TrueShape 3D printed tool inserts

Mantle printed conformal cooled medical forceps tool inserts via TrueShape technology using H13 Flowable Metal Paste. (Mantle’s 3D printed inserts were accurate to 0.0015″.)

At the recent AMUG Conference and Plastics Technology Expo in Illinois, metal 3D printing technology company Mantle Inc. showcased the results of three successful tooling collaborations, each using its TrueShape Hybrid Metal AM and H13 Flowable Metal Paste. . First it was Connecticut-based Westminster Tool, which needed to manufacture cavity and core tool inserts in order to quickly mold sample parts for medical forceps. The company wanted to mold the clips from Arkema’s bio-based, glass-filled Rilsan FKZM 65 O TD MED, supplied by Foster Compounds and used for surgical device applications. Mantle’s TrueShape was used to 3D print the tool’s inserts, designed with shaped cooling channels, in just 86 hours, with a tolerance of +/- 0.0015”.

Another Connecticut company, Wepco Plastics, designed inserts and cooling channels made from Mantle’s TrueShape while molding a cell phone mount. After 3D printing them in 80 hours by Mantle, the parts were molded in blue and black ABS plastic. Amanda Wiriya, Wepco Manufacturing Support Manager, reports that they had smooth surface finishes and were very easy to remove from the tool. Finally, New York-based Precision Laser Technology (PLT), which offers laser welding, engraving, texturing, and direct part marking for injection molds and molded plastics, participated in a study with Mantle to verify that its H13 materials could withstand machining and welding without having to change these processes. Mantle 3D printed four test bars of H13, and after precision milling and grinding, the results were, according to the press release, “indistinguishable from traditional H13 tool steel.”

Japan-based Kimura Foundry Group, which is a global network of foundries providing high-quality castings, now owns the largest number of ExOne 3D printers in the world with the purchase of its 10th desktop metal sand digital 3D printer . Traditional casting means waiting nearly 40 days for tooling, but Kimura is a major adopter of AM, allowing him to 3D print cores and molds in ceramic sand and create foundry prototypes in just five days. Kimura invested in its first ExOne sand binder injection systems in 2013, which saw its revenues skyrocket due to the design freedom and speed enjoyed by its customers. It launched a direct molding process with six ExOne binder jet printers in various Japanese facilities, established Kimura Foundry America in 2018, and is building a new foundry in Indiana around ExOne sanded binder jetting. Now, with his recent purchase, Kimura will install his third S-Max platform printer in the US.

“We are honored that Kimura, a foundry company with such high quality standards, continues to choose us as their choice for digital foundry solutions. Kimura Foundry Group is truly at the forefront of using additive manufacturing production, and is an important partner in our mission to demonstrate the benefits of additive manufacturing 2.0 across all industries,” said Ric Fulop, Co-Founder and CEO of Desktop Metal.

European researchers print drugs in 3D in seven seconds

A team made up of researchers from University College London (UCL), FabRx Ltd., the University of Santiago de Compostela and the MERLN Institute for Technology-Inspired Regenerative Medicine at Maastricht University published a study on their work in developing a new vat polymerization technique for 3D printing. medications in just seven seconds. Vat curing has very high resolution for microscale printing and also does not require intense heat, but it is not very fast. The team discovered a way to print an entire object in one go by projecting multiple images of the object, viewed from different angles, onto the resin, resulting in a much faster print speed. The amount of light shining down gradually accumulates until polymerization occurs, and all points of the 3D object in the resin can be reached at the same time by adjusting the light intensity at different overlaps and angles. They demonstrated their work by 3D printing printlets loaded with paracetamol.

The abstract reads: “In this work, for the first time, a volumetric printer was used to manufacture drug-loaded 3D-printed tablets (Printlets™) in seconds. Six resin formulations were evaluated with this printer, each consisting of poly(ethylene glycol) diacrylate (PEGDA) as the crosslinking monomer, lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP) as the photoinitiator, and acetaminophen as the model drug. Water or PEG300 were included as diluents in varying concentrations to facilitate drug release. The acetaminophen-loaded Printlets were successfully fabricated in 17 s. Drug release rates could be adjusted by altering the monomer to diluent ratio of the photosensitive resin, with a lower ratio releasing drug more rapidly. The present work confirms the suitability of volumetric 3DP for the printing of pharmaceutical products in a matter of seconds. Upon further optimization, this new technology can enable rapid, on-demand manufacturing of drugs and medical devices.”

Dubai RTA 3D printing spare parts to maintain roads and facilities

The Dubai Roads and Transport Authority (RTA) has a new solution to maintain your roads and road facilities. The agency is using 3D printing to manufacture the necessary replacement parts for the lining materials and the electromechanical systems used for this maintenance. The Executive Director of the RTA Roads and Traffic Agency, Ing. Maitha bin Adai, recently reiterated how important it is to keep up with innovative systems and technologies, and the use of 3D printing to manufacture these spare parts as well. will help Dubai RTA to realize the general 3D of the government. print targets. The Highways and Traffic Agency worked with three 3D printing companies for this initiative.

bin Adai said, “Over the past few months, RTA has developed a new initiative and conducted various studies and experiments to increase the availability of spare parts for road maintenance systems, in cooperation with specialized 3D printing companies. The initiative has been successful in expanding sources of spare parts, such as propeller fans, control equipment and lining for tunnel walls in Dubai’s road facilities.

“As part of the initiative, selected types of parts were chosen to be 3D printed; based on specific criteria, such as the lack of spare parts in local markets and taking into account safety measures. The initial results of the technology implementation revealed a 50% savings in the operating cost of purchasing spare parts. Additional improvements to factory replacement parts were made due to analysis of historical data, reducing failure rates to record levels. 3D printing technology has also helped reduce the cost of transportation and the time it takes to import spare parts to Dubai.”

3D printed boards from plastic waste

Finally, multidisciplinary design studio Uido has unveiled a line of 3D-printed waterboards made from plastic waste and old prototypes. The two designers, Lautaro Lucero and Tadeo Lucero, drafted their idea and, after a couple of iterations, created a fin-like look for the Wabo Handboards. In an effort to reduce waste and create a more environmentally friendly product, they shredded the plastic from the discarded prototypes, made 6mm plates to cut out, pressed the plastic into a mold, and placed the elastic handboard strap on top.

“At Uido, whenever we do a product design project, it’s an essential part of the process to make 3D printed prototypes. that’s why, throughout the year, we fill tons of boxes with those prototypes of different colors and sizes. Our commitment to the planet is serious, and our only waste as a company is those prototypes, so we started thinking about what we can do with them and how we can transform them into a fun new product. This is how the idea of ​​making handboards to surf waves was born”, said Lautaro Lucero.
