NVBOTS is making 3-D printing as simple as printing on paper

If you haven’t used a 3-D printer yet, you may be surprised to learn that it isn’t fully automated the way your office’s inkjet is. With paper printers, users queue documents from a computer, and each finished sheet drops neatly into a tray, waiting to be collected. With commercial 3-D printers, however, designs are manually … Continue reading “NVBOTS is making 3-D printing as simple as printing on paper”

3D-printing Bricks using Moondust and Sun’s Heat.

Bricks have been 3D printed out of simulated moondust using concentrated sunlight. This ESA project took place at the DLR German Aerospace Center facility, with a 3D printer table attached to a solar furnace, baking successive 0.1 mm layers of moondust at a temperature of 1000°C. A 20 x 10 x 3 cm brick for … Continue reading “3D-printing Bricks using Moondust and Sun’s Heat.”

New 3-D Printing Method Creates Shape-Shifting Objects

A team of researchers from Georgia Institute of Technology and two other institutions has developed a new 3-D printing method to create objects that can permanently transform into a range of different shapes in response to heat. The team created the objects by printing layers of shape memory polymers with each layer designed to respond … Continue reading “New 3-D Printing Method Creates Shape-Shifting Objects”

Reinventing Metal 3D printing with new Direct Writing process

Metal 3D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations. Parts produced using selective laser melting (SLM) and other powder-based metal techniques often end up with gaps or defects caused by a variety of factors. To … Continue reading “Reinventing Metal 3D printing with new Direct Writing process”

New 3-D-printed device mimics the Goldbug Beetle, which changes color when prodded.

New 3-D-printed device mimics the goldbug beetle, which changes color when prodded. In this age of smartphones and tablet computers, touch-sensitive surfaces are everywhere. They’re also brittle, as people with cracked phone screens everywhere can attest. Covering a robot — or an airplane or a bridge — with sensors will require a technology that is … Continue reading “New 3-D-printed device mimics the Goldbug Beetle, which changes color when prodded.”
