Soft, shape-changing materials are attracting growing interest in applications ranging from robotics to wearable devices, but conventional 3D printing methods are limited to a single actuation mode in ...

Welding is typically used to join two parts together, whether those parts be metal or plastic. There are various styles of welding, but we won’t go into those here. Casting is the act of pouring a ...

An experimental hollow-tube extrusion approach could dramatically accelerate large-scale 3D printing while reducing material use, though significant ...

3D printing may be a breakthrough technology, but it isn't sustainable. Most printers still rely on petroleum-based plastics, while greener alternatives are too brittle to use in parts that need ...

Researchers have developed a new approach to nanoscale 3D printing that improves both speed and fidelity, overcoming a ...

Researchers have developed a way to 3D print custom micrometer-sized structures directly into the interior of living cells. As reported in Advanced Materials, the investigators used their method to ...

Scientists have developed a 3D concrete printing method that captures carbon, demonstrating a new pathway to reduce the environmental impact of the construction industry. Scientists at Nanyang ...

Researchers at EPFL have demonstrated a light-based 3D-printing method that's about 30 times faster than conventional additive manufacturing, creating objects in 20 seconds that would normally take ...

Taking a cue from the structural complexity of trees and bones, engineers have created a way to 3D-print two types of steel in the same circular layer using two welding machines. The resulting ...

A rapidly expanding area of research in materials science involves the development of routes to complex 3D structures with feature sizes in the mesoscopic range (that is, between tens of nanometres ...
