Ground plastic bits go in one end, finished 3D-prints come out the other. That’s the idea behind [HomoFaciens]’ latest build: a direct-extrusion 3D-printer. And like all of his builds, it’s made from ...

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 ...

There was a time when the curious hardware hacker had to build their own 3D printer, because commercial models were so expensive as to be unaffordable except by well-funded institutions. We’re ...

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 ...

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.

Most desktop 3D printers offer a fairly limited print volume, but cultivate3d is looking to change this with the launch of ‘The Beast’ 3D printer that has taken to Kickstarter to raise the $10,000 ...

The Creality Ender-3 Max Neo is a great starter 3D printer for those who want to produce much bigger plastic creations than you'd normally get on an entry-level printer. After quite a few years and ...

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 ...
