The multi-material process enabled the printing of conductive and insulating materials inside the same object, creating a helical dielectric elastomer actuator (HDEA) with individually addressable conductive channels.

That allows the printed object to change shape when electricity is applied, and could be used in robotics, biomedical devices and other ‘smart’ materials.

US Navy Warship Installs Metal 3D Printer For Tools & Parts


Via “In 2022, the USS Essex became the first American Navy warship to install a metal 3D printer to ensure onboard repair capabilities of much-needed tools and parts. Now, the USS Bataan is following in its footsteps. The Naval assault ship announced the complete installation of a metal 3D printer on November 3, 2022. We have learned that the machine is a Phillips Additive Hybrid powered by Meltio and Haas.”

I think this trend will continue in many industries, providing a quick way to manufacture replacement parts on demand.

Creating Shapeshifting Materials That Change With Button Press


Researchers at Fraunhofer are currently working on programmable materials that can change shape on demand. One of the first applications will be for matresses, aiming at stopping bed sores for bed-ridden patients. Initial pilot projects with industry partners are already underway.

Multi-Material Digital Light Processing 3D Printing


A joint team of researchers from Japan and Singapore have developed a new technique for creating high resolution (40µm) hybrid plastic/metal parts. It’s called multi-material digital light processing 3D printing (MM-DLP3DP).

Similar to standard resin 3D printing, this process adds a few extra steps. Firstly the printer uses both resin and a pre-cursor material. Once printed, the parts are further processed in a plating bath, and the pre-cursor material is plated, while the standard resin is not. This allows for intricate and nested plated metals and could potentially be used as a way to create 3D circuits.

New Fabric Coating Responds To Toxic Gases By Changing Color

Dartmouth College

A team of researchers at Dartmouth College have developed a durable coating which can be precisely integrated into fabrics, to create responsive sensors for protective equipment and more.

The coating is based on a conductive metal-organic framework (MOF), which can respond to the presence of toxic gases in the air by converting them into less toxic substances that become trapped in the fabric.

UCalgary Researchers Create 3D-printed Materials With Liquids


The team added nanoparticles to water and chemical compounds, or surfactants molecules, to oil. One of the researchers, Dr. Hossein Hejazi explains, “By injecting this water into the oil, the interface between the oil and water spontaneously turns into emulsion, forming an interfacial skin made of many tiny water droplets that are sticking together.”

This creates 3D tube-like structures in the oil, which can be injected with other materials, and this liquid-in-liquid process could enable many potential uses including energy storage, microreactors, and for creating biomimetic materials like tissues and polymers.
