Desktop 3-d printing has largely been the domain of extrusion-based machines like MakerBot's Replicator and DIY RepRap designs.
On our recent visit to Formlabs for a demonstration of the Form 1, we were left highly impressed.
Plastic isn’t deposited on a build platform; instead, parts are extracted from a gooey pool of resin. In addition to its higher accuracy, this process also makes translucent parts and complex geometries possible. It can print objects 4.9 by 4.9 by 6.5 inches with layers that are just 25 microns (0.001 inches) thick.
To put this in perspective, the Form 1 resolution is four times higher than the new MakerBot Replicator 2 (100-micron layer thickness), and is on par with professional grade systems. With tolerances this tight, designers will be able to produce high quality presentation models suitable for painting, small runs of production parts, and models with enough detail to be used in jewelry casting.
While SpaceX works on giant reusable rockets to reach Mars, other companies are working on technologies to keep colonists alive on the red planet. Relativity Space has made the world's largest metal 3D printer, called Stargate, to print rockets, tools, and other useful objects off-Earth.
When humans take the drug MDMA, versions of which are known as molly or ecstasy, they commonly feel very happy, extraverted, and particularly interested in physical touch. A group of scientists recently wondered whether this drug might have a similar effect on other species—specifically, octopuses, which are seemingly as different from humans as an animal can be. The results of their experiment, in which seven octopuses took MDMA, were “unbelievable.”
