A new research paper introduces a compact screw-based pellet extruder for high content feedstocks, and it could materially shift costs and throughput for polymer, metal and ceramic additive ...

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 ...

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 ...

It would be great if you could create your own filament. On the face of it, it seems easy to do, but as [Thomas Sanladerer] found out when he was a student, there are a lot of details that can bedevil ...
