3D printing gets faster, with help from a vat of goo

Ben Coxworth for New Atlas:  Although 3D printing may be revolutionizing the world of manufacturing, it still takes rather a long time to do when compared to some of the alternatives. A collaboration between MIT's Self-Assembly Lab, Steelcase and product designer Christophe Guberan, however, has resulted in a new technique known as Rapid Liquid Printing – it can reduce the time of some 3D print jobs from hours to minutes.

Normally, 3D-printed objects have to be built up on a platform one layer at a time. In some cases, supporting structures need to be added during the build process, which are subsequently removed and discarded.

With Rapid Liquid Printing, though, the print nozzle extrudes a polymer material directly into a container of translucent gel. That gel holds the material in place, so no supporting structures are necessary. It's sort of like being able to draw the object in mid-air, except it's in mid-gel.

Additionally, while some traditional 3D printing materials must be cured via exposure to heat or UV light, the two-part material used in Rapid Liquid Printing chemically hardens upon contact with the gel. Once the object has been printed – and its size is limited only by the size of printer and gel container – it's simply pulled out and rinsed off.  Full Article:

ROBOTMASTER V7

ROBOTMASTER V7

Since Robotmaster V7 uses integrated CAD/CAM functionality, for the first time, the power of Robotmaster can be used by welding, cutting and other process experts without buying or learning complex CAD/CAM software. As in past versions, Robotmaster V7 imports paths, but now makes it even easier for end users to leverage any CAD/CAM tool choice. It is an intuitive tool that anyone could use, with or without robotics expertise. It bridges the gap between robots and manufacturing by providing easy programming solutions for part manufacturing.
