A patent proposal by Thermwood could solve one of large area extrusion’s oldest challenges: keeping bead size consistent when a pellet fed printhead speeds up, slows down, and corners.

Air-cooled blown-film extrusion machines can allow energy loss through convection cooling when the dampers are closed, victims of the so-called 'chimney effect'. A new extruder design removes heat and ...

Purging the blow molding machine on the shop floor will ensure efficient performance and a better end product. While there are some differences between standard and custom blow molders, the blow ...

Hugh Lyman, an 83-year-old retiree from Enumclaw, Washington, won The Desktop Factory Competition with his design for a low-cost, open-source machine capable of turning resin pellets into inexpensive ...

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 ...

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.
