3D Printing/Additive Manufacturing

Researchers at Sandia National Laboratories have developed a much faster 3D printing process using dual-wavelength light that yields tougher, stronger nonmetallic parts.

Researchers at the KTH Royal Institute of Technology and Stockholm University in Sweden have unlocked a game-changing potential in 3D printing technology. By hacking into a 3D printer, they’ve transformed it into a versatile tool akin to a laser printer, capable of printing various polymers without the need for solvents, chemicals, or stringent clean room conditions.

With the growing demand for environmentally friendly activities and considering that 37% of global greenhouse gas emissions are currently generated by the construction sector, the implementation of sustainable construction has become a necessity.

In the extensive world of materials science and industrial processes, selecting the right rheometer for our specific applications often feels like navigating a complex puzzle. Each piece must fit precisely to unlock the full potential of material characterization,  R&D, and process optimization.

Have you considered the potential of transforming household fruit and vegetable waste into 3D printing filaments? The BARBARA project has successfully developed biopolymers, enhanced with bio-additives derived from food waste, for the additive manufacturing of components.

A pair of U.S. defense-related organizations –– America Makes and NCDMM –– have awarded funds to a project designed to optimize recycled PET (rPET) and rPET-based composites in filament-fed material extrusion 3D printing.

Melt Electrowriting (MEW) emerged in the biomedical and tissue engineering outlook over a decade ago as a method for printing structures on the low micrometer or nanometer scale. But how does it work, and what does the future hold for this technology?

Traditional fiberglass casts, though an improvement over plaster ones, have their drawbacks. They aren’t waterproof, leading to water absorption and unpleasant odors. Moreover, wearers still need to protect the cotton padding beneath from getting wet. Recognizing these issues, the Cast21 team set out to create a patient-friendly solution.

In a groundbreaking endeavor, mechanically recyclable thermoplastic materials were harnessed to craft lightweight and highly efficient aerogel filter media for air filtration. Leveraging the fused filament fabrication (FFF) 3D printing technique, this project focuses on creating an all-polyolefin composite filter media.

Stratasys partners with the National Occupational Competency Testing Institute (NOCTI) to introduce a High-Standard FDM Process Certification. The global 3D printing market in terms of revenue was estimated at USD 15 billion in 2023 and is expected to reach USD 34.5 billion by 2028 with a CAGR of 18.1%. This makes it an appealing market for young professionals, although certifications may be necessary.

3D printing has emerged as a game-changer in the medical field, particularly in the development of prosthetics and orthotics. While the technology allows for highly customizable solutions, challenges persist, especially concerning the limited availability of these prosthetics. However, a recent breakthrough in 3D printing research by Loughborough University could potentially revolutionize the creation of prosthetic sockets.

Stratasys and Siemens Healthineers partnered to develop a technology that translates information from scanned patient images (CT) into 3D-printed phantom models with specific material characteristics that emulate the radiopacity of human anatomy.
