3D printers can make objects of practically any shape you can dream up, but despite the fact that they’re so capable, there’s one thing that they often struggle with: overhangs. Filament-based 3D ...

Most of the time FDM 3D printing involves laying down layers of thermoplastics, but the layer lines also form the biggest weakness with parts produced this way. Being able to lay out the lines to ...

Two researchers at Penn State have created a new system for five-axis additive 3D-printing that reduces the amount and density of support materials needed for making printed objects. In a paper ...
