When it comes to innovation in FDM 3D printing, there doesn’t seem to be much room left to move the needle. Pretty much everything about filament printing has been reduced to practice, with more or ...

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.

This patent might be part of the solution. It describes (in tedious patent language) what could be a new type of filament ...

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 ...

However, industrial 3D printing machines differ greatly from traditional desktop printers. Besides the format of the machines and the prints, one major difference can be found in the material that is ...

Entrepreneurs in Denmark have taken another step towards improving the general usability of 3D printers with the Diamond Hotend, a single 3D extruder unit that can mix and melt three filaments ...

The problem: folk are finding wear and gouging under the driven hobbed gear of a certain type of dual-drive extruder. In the photo right of a partially assembled dual-drive, it would be in the red ...

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 ...
