Researchers utilize 3D printing to produce lattice structures for bone regeneration

A group of researchers utilized selective laser melting (SLM) 3D printing to produce titanium lattice structures as scaffolds for bone regeneration.

According to their study, “bone replacement materials need to be accepted by the body and should clinically be infiltrated with bone tissue within a short time,” which makes them osteoconductive.

The implants, which were perfectly matched the size and shape of the bone defect, were used on 18 adult rabbits.

After four weeks, researchers removed and studied the implants to determine how well they had stimulated bone growth.

The results showed that the best results were achieved at a rod distance of 0.8 mm and a rod caliber of 0.3 to 0.4 mm.

Architectural fabricator builds world’s largest 3D-printed structure

A Tennessee-based architectural fabricator built the world’s largest 3D-printed structure out of carbon fiber-reinforced Acrylonitrile Butadiene Styrene.

The designers of the structure teamed up with a structural engineering firm to optimize its design (open cell structure) and eliminate the need for supplemental steel reinforcement.

“The open-cell nature allows for efficient builds and endless geometric form,” a press release stated. “For architectural application, the matrix acts as a formwork or scaffold to accept traditional building materials.”

The design resulted in a product that is “as robust as it is revolutionary.”

3D printing system to produce autonomous robots

Researchers from various organizations collaborated to develop a 3D printing system which they will use to create autonomous robots for extreme nuclear environments.

The group of researcher from the Bristol Robotics Lab, the University of York, Edinburgh Napier University, and the Free University of Amsterdam began the four-year Autonomous Robot Evolution (ARE) earlier this year to explore new design approaches for robotics operating in foreign and extreme environments.

The researchers started the development of the project after being granted with a fund from the Engineering and Physical Sciences Research Council (EPSCR).

The ARE project aims to create its own technology to enable automated 3D printed robotics that will help in the production of evolutionary autonomous robotic ecosystems that can operate for long periods in extreme environments.

US Gov’t Allows Return Of 3D-Printed Gun Blueprints

Four years after the US government ordered the removal of 3D-printed gun files found on the internet, the United States Justice Department ruled that it can now be returned online.

The previous decision claimed that the files violated the International Traffic in Arms Regulation, which was disputed jointly by the Defense Distributed and Second Amendment Foundation, the organizations that defend the right to own guns.

Today, the US Justice Department allows Americans to “access, discuss, use, and reproduce” the technical data of 3D printed guns.
