Vat photopolymerization, a light-based 3D printing technique, conventionally relies on UV light to rapidly transform liquid resins into intricate solid objects. However, the use of visible light as an ...

An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when ...

ANN ARBOR--Rather than building up plastic filaments layer by layer, a new approach to 3D printing lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3D printing ...
