Lawrence Livermore National Laboratory (LLNL) researchers have become the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the lightweight, yet stronger than steel material.

The research, published by the journal Nature Scientific Reports online on Feb. 28, represents a “significant advance” in the development of micro-extrusion 3D printing techniques for carbon fiber, the authors reported.

A 3D bioprinter able to create human skin is already being used to help burns patients and carry out skin testing, Alfredo Brisac, CEO of Spanish bioengineering company BioDan, told Radio Sputnik.

Last month, scientists at Universidad Carlos III de Madrid and the BioDan Group presented a prototype 3D bioprinter that can create human skin suitable for transplantation to patients or for use in cosmetic, chemical or pharmaceutical testing.

One of the first living human organs to be created using bioprinting, the 3D-printed skin is created using bio-inks with living cells that are deposited onto a structure that replicates nature. The bio-ink contains the key elements of keratinocytes, fibroblasts and fibrin, which can recreate the structure of the skin.

New research describes a novel 3D printing technique for the production of smart materials that may find use in soft-robotics and advanced medicine.

In a recent academic paper the, “striking phenomena” that “can be produced by embedding magnetic particles into polymer with designed patterns,” are described in detail. These phenomena include smart materials with, “tunable elastic properties, giant deformational effects, high elasticity, anisotropic elastic and swelling properties, and quick response to magnetic fields.”

As previously reported by 3D Printing Industry, investigations into smart and meta materials are increasingly using 3D printing techniques.

The startup Daqri has improved on additive manufacturing production speeds by developing holographic 3D printing, yet not without limitations.

Scientists from the Universidad Carlos III de Madrid (UC3M), CIEMAT (Center for Energy, Environmental and Technological Research), Hospital General Universitario Gregorio Marañón, in collaboration with the firm BioDan Group, have presented a prototype for a 3D bioprinter that can create totally functional human skin. This skin is adequate for transplanting to patients or for use in research or the testing of cosmetic, chemical, and pharmaceutical products.

This research has recently been published in the electronic version of the scientific journal Biofabrication. In this article, the team of researchers has demonstrated, for the first time, that, using the new 3D printing technology, it is possible to produce proper human skin. One of the authors, José Luis Jorcano, professor in UC3M’s department of Bioengineering and Aerospace Engineering and head of the Mixed Unit CIEMAT/UC3M in Biomedical Engineering, points out that this skin “can be transplanted to patients or used in business settings to test chemical products, cosmetics or pharmaceutical products in quantities and with timetables and prices that are compatible with these uses.”

Think you’ve seen it all when it comes to 3D printing? This hologram-powered 3D printer prints using green lasers and a tub of goo.

OMG? Are we going to have super cheap electric vehicles in a few years that charge in a few seconds/minutes?

I hope so! This is very exciting.

Australia has supercapacitors made from graphene oxide. They can can store as much energy per kilogram as a lithium battery, but charges in minutes, or even seconds, and uses carbon instead of expensive lithium.

NASA has enlisted a professor from the University of Central Florida (UCF) in order to find a way of 3D printing structures on Mars.

Pegasus Professor Sudipta Seal, interim chair of UCF’s Materials Science and Engineering program is looking at how metals can be extracted from Martian soil. Speaking about the project, Seal said,

It’s essentially using additive-manufacturing techniques to make constructible blocks. UCF is collaborating with NASA to understand the science behind it.
