the animals may remain stressed. For custom-made objects, 3D printers may prove useful in keeping up with demand—once a design is acquired, objects could be printed as needed—but there isn’t much ...

For example a cube has 8 vertices. 2D shapes are boring. Ah! Not really. But got your attention. Now. 3D shapes, they have 3 dimensions. Length, width and depth. What would the 3D version of a ...

in India are working on what they believe could be a compromise—offering the reliability of animal testing without the suffering. Their proposed solution: artificial “skin” made of 3D ...

Scientists have developed a 3D-printed imitation of human skin with living cells, an advance they say could enable cosmetic testing without the use of animals. Researchers, including from the ...

Recyclable plastic objects can be 3D-printed using light 1. 3D printing can quickly make objects with complex shapes. But recycling those products into ones that are equally tough is a challenge.
