New software algorithms reduce the time and material needed to produce objects with 3-D printers. Here, the wheel on the left was produced with conventional software and the one on the right with the ...

Some things are easier to 3-D print than others. We know, for example, that we can 3-D print pierogi molds no problem. But engineers have been trying to crack the 3-D printed house for quite some time ...

Machine learning has returned with a vengeance. I still remember the dark days of the late '80s and '90s, when it was pretty clear that the current generation of machine-learning algorithms didn't ...
