3D printed gearboxes are great for experimental designs, but due to roughness and inaccuracies in the printed surfaces, they can wear quickly and be rather noisy. As a possible alternative, [Resetman] ...

Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a permanent ...

(a) Schematic of the multi-material one-step printing process, demonstrating the sequential switching of three different resin tanks during printing to achieve composite structures in a single step.

The treatment of gastrointestinal and urinary system diseases has long been plagued by limitations of traditional drug delivery methods, such as low drug concentration at target sites, lack of ...

To publicly demonstrate the powerful and as-yet-untapped capabilities of 3D printing, Luis Fernando Velásquez-García, a principal research scientist at MIT, had his team use it to make a miniature ...

3D bioprinting, in which living tissues are printed with cells mixed into soft hydrogels, or "bio-inks," is widely used in ...

A new class of lab-developed “field-responsive mechanical metamaterials” (FRMMs) employ a viscous, magnetically responsive fluid that is manually injected into the hollow struts and beams of ...
