Laser Inversion enables Multi-Materials 3D Printing

Selective laser sintering is one of the most widely used processes in additive manufacturing, but it is limited to printing with a single material at a time. Columbia engineers have used their expertise in robotics to develop a new approach to overcome this limitation: By inverting the laser so that it points upwards, they’ve invented a way to enable SLS to use—at the same time—multiple materials.

‘SlothBot in the Garden’ Demonstrates Hyper-Efficient Conservation Robot

For the next several months, visitors to the Atlanta Botanical Garden will be able to observe the testing of a new high-tech tool in the battle to save some of the world’s most endangered species. SlothBot, a slow-moving and energy-efficient robot that can linger in the trees to monitor animals, plants, and the environment below, will be tested near the Garden’s popular Canopy Walk.

A Great New Way to Paint 3D-Printed Objects

Rutgers engineers have created a highly effective way to paint complex 3D-printed objects, such as lightweight frames for aircraft and biomedical stents, that could save manufacturers time and money and provide new opportunities to create “smart skins” for printed parts. The findings are published in the journal ACS Applied Materials & Interfaces.

Robot Uses Artificial Intelligence and Imaging to Draw Blood

Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.
