Think laying down molten plastic on a 3D printer is as easy as squeezing plastic filament out of a hot tube? It’s not, and anyone who had a 3D printer in 2009 would tell you as such. There were hobbed ...

The holy grail of desktop 3D printers – aside from manufacturing full color objects in any shape imaginable – is turning tiny plastic pellets into a plastic filament. Many projects have attempted this ...

Last week, we took a first look at the dual-filament Ultimaker 3 printer. This week, we dive into one of the key features that provides the printer with its power and flexibility: its extruders.

Extruders are devices that heat and melt the feedstock and extrude it through the nozzle along a predetermined path on the print bed. Based on the material feeding, 3D printers are classified as ...

One of the issues with 3D printing is the amount of waste that is generated when creating prototypes, mockups and testing your designs. One way to combat this is to break up your unwanted prints and ...
