If a 3D printer leaves gaps in the plastic that it deposits, it's usually thought of as an unwanted flaw. Now, however, the process has been harnessed to quickly and cheaply produce pliable polymer ...

3D printers are exact and are a fantastic way to print complicated parts that couldn't be built otherwise. However, sometimes 3D printers make mistakes by extruding too much material, too little, or ...

3D printers usually work by extruding long strings of molten plastic onto a surface. When MIT Media Lab researchers spotted a broken printer squirting out plastic erratically, they had an idea: By ...
