Recycling plastic into filament normally involves chopping it into tiny pieces and pushing it through a screw extruder. [JRT3D] is taking a different approach with PetBot, which cuts PET bottles into ...

Didyou know that 3D printing generates a lot of plastic waste? This mayseem odd at first, but every enthusiast knows the amount of plasticthat gets wasted before any successful printing is done.

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 ...

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.

Three engineering physics students at the University of British Columbia have developed a desktop plastic recycler and extruder that turns plastic waste into the material needed for 3D printing.

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 ...

Fancy filament isn't always the answer ...

For all its transformative potential, the high costs of 3-D printing continue keeping it from achieving mass consumer adoption. Now a new open source device may change that with its ability to create ...

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 ...

Q: Are We Not Men? A: We are 3devo! A Dutch startup, 3devo, part of the engineering company Detoteq, has developed a filament extruder for 3-D printing, called the Next 1.0, aimed at the “maker” ...
