We have seen 3D printed buildings before but most of them were prototypes, built off-site or not used afterwords, but nothing compares to this house built by Apis Cor.
Apis Cor used a unique house 3D printing machine they developed and made an on-site house in 24 hours for the cost of some 10000 USD. It has surface of 38 square meters (409 square foot) and has been built in Stupino town, Moscow region, Russia.
The finished house is fully livable with all the appliances. Very cool!
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.
“The mantra is ‘if you could make everything out of carbon fiber, you would’—it’s potentially the ultimate material,” explained Jim Lewicki, principal investigator and the paper’s lead author. “It’s been waiting in the wings for years because it’s so difficult to make in complex shapes. But with 3D printing, you could potentially make anything out of carbon fiber.”
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.
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.”
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.”
This new human skin is one of the first living human organs created using bioprinting to be introduced to the marketplace. It replicates the natural structure of the skin, with a first external layer, the epidermis with its stratum corneum, which acts as protection against the external environment, together with another thicker, deeper layer, the dermis. This last layer consists of fibroblasts that produce collagen, the protein that gives elasticity and mechanical strength to the skin.
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.
Large-scale production of the graphene that would be needed to produce these high-performance supercapacitors was once unachievable.
By using low-cost solution-based film synthesis techniques and a laser 3D printer, the researchers are able to produce graphene on a large scale at low cost.
