In contrast to the success of their molten-plastic cousins, paste extrusion 3D printers have never really attained much popularity. This is shame because, as the [Hand and Machine] research group at ...

It’s safe to say toolchanging on 3D printers has stepped to the front, but what comes next? What kind of tools other than extruders make sense on a 3D printer? First, let’s explain what makes separate ...

This transparent view of a parallel twin-screw extruder illustrates the structure of the basic hardware that accomplishes compounding and end product extrusion in one step without subjecting the ...

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 ...
