Advanced Tech and Life Science on Station Today Promoting Health

Posted by in categories: 3D printing, bioprinting, biotech/medical, health, nanotechnology, science, space travel

Nanomaterials manufacturing, 3D bioprinting, and astronaut eye health were the main research topics aboard the International Space Station on Friday. The Expedition 71 crew members also continued servicing spacesuits and conducted an emergency drill.

The SpaceX Dragon cargo spacecraft recently delivered to the orbital outpost a biotechnology study to demonstrate the in-space production of nanomaterials that mimic DNA. NASA Flight Engineers Jeanette Epps and Mike Barratt worked on the second portion of that experiment on Thursday mixing then treating the research samples for analysis. Epps began her day mixing solutions in the Life Science Glovebox to create specialized nanomaterials. During the afternoon, Barratt applied sound and light treatments to the samples then stowed them aboard Dragon for analysis back on Earth. Results may lead to advanced therapies for space-caused and Earthbound health conditions.

The duo partnered back together at the end of the day for eye scans using standard medical imaging gear found in an optometrist’s on Earth. Barratt operated the hardware with guidance from doctors on the ground peering into Epp’s eyes and examining her retina and optic nerve for the B Complex eye health investigation.

New 3D-printing method makes printing objects more affordable and eco-friendly

Posted by in categories: 3D printing, materials

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 3D print new ultra-realistic heart and lung models that can bleed, beat, and breath

Posted by in categories: 3D printing, biotech/medical

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.

From Neuronal Differentiation of iPSCs to 3D Neuro-Organoids: Modelling and Therapy of Neurodegenerative Diseases

Posted by in categories: 3D printing, bioprinting, biotech/medical, neuroscience

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.

Stanford’s 3D printer can now print million dust-sized particles a day

Posted by in categories: 3D printing, biotech/medical

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.

Video: Europe’s biggest 3D-printed building rises in just 140 hours

Posted by in categories: 3D printing, computing

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.

3D-printed skin closes wounds and contains hair follicle precursors

Posted by in categories: 3D printing, bioprinting, biotech/medical, engineering

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.

Chameleons inspire new Multicolor 3D-Printing Technology

Posted by in categories: 3D printing, chemistry, engineering, sustainability

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.
