3-D+Printing

A first-of-its-kind 3D-printed concrete bridge has been unveiled in Venice, Italy. The bridge is a demonstration of a new 3D printing method resulting in a structure requiring no mortar or steel reinforcement.

WASP, in collaboration with artist Alison Knowles, has completed the printing stage of the world’s first 3D-printed livable sculpture. “The House of Dust” will be one of 10 temporary sculptures featured at the Museum of Wiesbaden’s tinyBE exhibition.

Heating and cooling systems are some of the biggest energy guzzlers, but passive temperature control could reduce emissions. Phase-change materials show promise for this, and now engineers have developed a new PCM composite that can be 3D printed.

Relativity Space is coming to the 3D-printed rocket party with its freshly unveiled Terran R. Intended for satellite launches and multi-planetary travel, the rocket is fully reusable and can be created from raw materials within 60 days.

Scientists have developed a new way to patch up injuries by 3D printing both hard and soft tissues at the same time, using two different “bioinks.” In tests on rats, the team was able to repair holes in the skulls and skin of the rodents in minutes.

Researchers at the University at Buffalo have developed a new method for 3D printing graphene aerogels that work well as water filters. The team says this technique helps make graphene aerogels scalable and stable enough to be used over and over.

Saab has flown a 3D-printed replacement part on the exterior of a Gripen fighter jet for the first time on a test flight at Linköping, Sweden, potentially paving the way for printed parts to be used to make battlefield repairs.

Engineers at Cornell University have developed a new technique for 3D printing metallic objects – and it involves blasting titanium particles at supersonic speeds. The resulting metals are very porous, making them useful for biomedical implants.

Human knees are notoriously vulnerable to injury or wearing out with age, often culminating in the need for surgery. Now researchers have created new hybrid bioinks that can be used to 3D print structures to replace damaged cartilage in the knee.

Founder of Prusa Research, the world’s largest 3D printing factory located in Prague, Josef Prusa has spoken about how the company is doing everything it can to aid the production of much needed medical supplies during the COVID-19 crisis.

Last month, Ikea and teenage engineering launched the Frekvens collection of lighting and speaker modules. Now teenage engineering has added a bunch of CAD files to the mix so that owners can print off some nifty hacks.

Researchers from ETH Zurich have created 3D rabbit models embedded with synthetic DNA that contained their own blueprints. That allows them to effectively "clone" the models, printing copies by clipping small pieces off the original.
