University of Florida engineers have developed a method for 3D printing called vapor-induced phase-separation 3D printing, or VIPS-3DP, to create single-material as well as multi-material objects. The discovery has the potential to advance the world of additive manufacturing.
Researchers from Nottingham Trent University (NTU) have developed realistic 3D printed heart and lung models that can bleed, beat and breathe like their real counterparts.
Designed for organ transplant training, the lifelike models reportedly reflect the tactile qualities of a human heart and can be produced with various tissue hardness levels. Using the models, medical professionals can plan surgeries and safely research and teach transplant procedures, without the risk of complications.
The project, which was led by research fellow Richard Arm, leveraged 3D scans of both healthy and diseased human hearts to 3D print the models to a high level of accuracy.
A new fabrication process for helical metal nanoparticles provides a simpler, cheaper way to rapidly produce a material essential for biomedical and optical devices, according to a study by University of Michigan researchers.
In the last decade, the advances made into the reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) led to great improvements towards their use as models of diseases. In particular, in the field of neurodegenerative diseases, iPSCs technology allowed to culture in vitro all types of patient-specific neural cells, facilitating not only the investigation of diseases’ etiopathology, but also the testing of new drugs and cell therapies, leading to the innovative concept of personalized medicine. Moreover, iPSCs can be differentiated and organized into 3D organoids, providing a tool which mimics the complexity of the brain’s architecture. Furthermore, recent developments in 3D bioprinting allowed the study of physiological cell-to-cell interactions, given by a combination of several biomaterials, scaffolds, and cells.
Researchers at Rice University have unlocked the potential to use 3D printing to make sustainable wood structures, offering a greener alternative to traditional manufacturing methods.
These small particles that look like dust to the naked eye are highly detailed and can be customized to suit a wide variety of needs ranging from microfluidics to vaccine delivery and even microelectronics, a press release has said.
3D printing or additive manufacturing at a macroscale level has matured at the market level, where items like shoes, hearing aids, and even household goods can be made using this technique.
Tasked with building a new data center in an urban area of Germany, the team behind the Wave House harnessed the benefits of 3D printing technology to inject a sense of style into the unglamorous world of cloud-computing infrastructure, creating Europe’s largest 3D-printed building in the process.
The Wave House is located in Heidelberg and was designed by SSV and Mense Korte, and created by Peri 3D Construction for developer KrausGruppe. It measures 600 sq m (6,600 sq ft). As mentioned, its unusual appearance comes from an attempt to spice up what could otherwise have been a rather boring building.

Science: In future maybe wounds be cured and closed in seconds by 3D printing regeneration.
Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. The advancement could have implications for reconstructive facial surgery and even hair growth treatments for humans.
The team’s findings were published March 1 in Bioactive Materials. The U.S. Patent and Trademark Office granted the team a patent in February for the bioprinting technology it developed and used in this study.

Inspired by the color-changing ability of chameleons, researchers have developed a sustainable technique to 3D-print multiple, dynamic colors from a single ink.
“By designing new chemistries and printing processes, we can modulate structural color on the fly to produce color gradients not possible before,” said Ying Diao, an associate professor of chemistry and chemical and biomolecular engineering at the University of Illinois Urbana-Champaign and a researcher at the Beckman Institute for Advanced Science and Technology.
The study appears in the journal PNAS.
The proliferation of wearable devices—from smart watches to AR glasses—necessitates ever-smaller on-board energy solutions that can deliver bursts of power while remaining unobtrusive.
Scientists leverage additive-free 3D printing process to construct exceptionally customizable and high-performing graphene-based micro-supercapacitors tailored for on-chip energy storage.
