3D printing, also called additive manufacturing, has become widespread in recent years. By building successive layers of raw material such as metals, plastics, and ceramics, it has the key advantage of being able to produce very complex shapes or geometries that would be nearly impossible to construct through more traditional methods such as carving, grinding, or molding.

The technology offers huge potential in the health care sector. For example, doctors can use it to make products to match a patient’s anatomy: a radiologist could create an exact replica of a patient’s spine to help plan surgery; a dentist could scan a patient’s broken tooth to make a perfectly fitting crown reproduction. But what if we took a step further and apply 3D printing techniques to neuroscience?

Stems cells are essentially the body’s raw materials; they are pluripotent elements from which all other cells with specialized functions are generated. The development of methods to isolate and generate human stem cells, has excited many with the promise of improved human cell function understanding, ultimately utilizing them for regeneration in disease and trauma. However, the traditional two-dimensional growth of derived neurones–using flat petri dishes–presents itself as a major confounding factor as it does not adequately mimic in vivo three-dimensional interactions, nor the myriad developmental cues present in real living organisms.

University at Buffalo (UB) researchers have developed a novel 3D printed water-purifying graphene aerogel that could be scaled for use at large wastewater treatment plants.

Composed of a styrofoam-like aerogel, latticed graphene and two bio-inspired polymers, the novel material is capable of removing dyes, metals and organic solvents from drinking water with 100% efficiency. Unlike similar nanosheets, the scientists’ design is reusable, doesn’t leave residue and can be 3D printed into larger sizes, thus they now aim to commercialize it for industrial-scale deployment.

“The goal is to safely remove contaminants from water without releasing any problematic chemical residue,” explained study co-author and assistant professor of environmental engineering at UB, Nirupam Aich. “The aerogels we’ve created hold their structure when put into water treatment systems, and they can be applied in diverse water treatment applications.”

Turns out bones and 3D printing have a lot in common 🤔.

Learn how a young team of additive manufacturing engineers helped bring 3D printed parts to the design of the GE9X, the world’s largest jet engine.

Stefka Petkova enjoys building things. It’s a passion she’s had since she was a small child when her dad, an electrician who liked to work on cars, kept the door to his workshop open. “I was exposed to that as a very young child and just got a lot of encouragement,” says Petkova, who she spent many afternoons watching him weld and wire automobiles.

3D-printed parts can make rocket engines lighter, less expensive and more efficient.

At Marshall, we’re working with our industry partners to test the latest advances in additive manufacturing technologies:

NASA is partnering with Aerojet Rocketdyne to advance 3D printing technologies, known as metal additive manufacturing, and its capabilities for liquid rocket engines in landers and on-orbit stages/spacecraft.

Why luxury brands like Hermès, Iris Van Herpen, and Stella McCartney are turning to mushrooms for an eco-alternative to leather.

The wondrous fungi-inspired creations in Dutch couture designer Iris Van Herpen’s Spring 2021 collection are like nothing else in the fashion world. Undulating crowns of brass coils top delicate micro-plissé gowns with bodices formed from sinuous silk tendrils. An early adopter of 3D printing and advocate for sustainability, van Herpen has emerged as a kind of oracle within the fashion industry. She spent lockdown in Amsterdam reading biologist Merlin Sheldrake’s book, Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures, which describes the hidden world of mycelium, the sprawling underground root-like networks of fungi (the visible part we know as mushrooms are akin to fruit on trees).
