High “spatial ability” in adolescence, including the capacity to visualize 3D objects from 2D patterns, is a statistically significant predictor of later creativity in science and technology, says a ...

Makerbot is in the gutter, 3D Systems and Stratasys stock is only a shadow of their 2014 glory, but this is the best year 3D printing has ever had. Machines are now good and cheap, there’s a variety ...

Computer-aided design (CAD) is the go-to method for designing most of today's physical products. Engineers use CAD to turn 2D sketches into 3D models that they can then test and refine before sending ...

You know that feeling when your optical-tomography rig just can’t seem to handle 3D-scanning an object with occluded regions? So annoying! Ah, first-world problems. Well, now there’s a solution: a ...

Orthographic projections have a set of standard lines to show different aspects of the diagram. These lines allow complex shapes to be drawn simply in 2D. In third angle, what you see from the right ...

3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by ...
