Lustrous-colored 3D printing using liquid crystals

What do cosmetics, car finishes, passports, bank notes, tropical insects, and oysters have in common? The color is formed through a specific microscopic organization of the matter making up the material, often called "iridescent" ...

An improved ink for colon tattoos

The colon might be the last place people would consider getting a tattoo, but endoscopic tattooing is an important medical technique for marking colorectal lesions for surgery or follow-up. Today, scientists report a next-generation ...

Moving objects straight off the printer

It seems like science fiction: a flat object issues from the 3D printer, then starts to fold itself. Albeit in a limited way, 4D printing was already possible, but now TU/e researcher Marc del Pozo Puig has developed a smart ...

Microfountain pen draws minute patterns for live cells, circuits

Advances in intuitive microwriting devices that can print microstructures could pattern electric circuits and more. The setup, featuring a robot arm to hold the micropen, deposits ink onto the surface, much like writing by ...

3D nano-inks push industry boundaries

A new, 3D-printable polymer nanocomposite ink has incredible properties—and many applications in aerospace, medicine and electronics.

Turning pollen into 3D printing ink for biomedical applications

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have found a way to use sunflower pollen to develop a 3D printing ink material that could be used to fabricate parts useful for tissue engineering, ...
