Automated system generates robotic parts for novel tasks

An automated system developed by MIT researchers designs and 3-D prints complex robotic parts called actuators that are optimized according to an enormous number of specifications. In short, the system does automatically ...

Finding keyholes in metals 3-D printing

Additive manufacturing's promise to revolutionize industry is constrained by a widespread problem: tiny gas pockets in the final product, which can lead to cracks and other failures.

3-D printing 100 times faster with light

Rather than building up plastic filaments layer by layer, a new approach to 3-D printing lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3-D printing processes, University of Michigan ...

Origami, 3-D printing merge to make complex structures in one shot

By merging the ancient art of origami with 21st century technology, researchers have created a one-step approach to fabricating complex origami structures whose light weight, expandability, and strength could have applications ...

Changing the color of 3-D printed objects

3-D printing has come a long way since the first "rapid prototyping" patent was rejected in 1980. We've evolved from basic designs to a wide range of highly-customizable objects. Still, there's a big issue: once objects are ...

Novel 3-D printing technique yields high-performance composites

Nature has produced exquisite composite materials—wood, bone, teeth, and shells, for example—that combine light weight and density with desirable mechanical properties such as stiffness, strength and damage tolerance.
