Multimaterial 3D printing manufactures complex objects, fast

3D printing is super cool, but it’s also super slow — it would take 115 days to print a detailed, multimaterial object about the size of a grapefruit. A new method allows printing with up to 8 different inks in a fraction of the time, thanks to special printheads that can seamlessly switch inks up to 50 times per second. https://www.sciencedaily.com/releases/2019/11/191113153106.htm
