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 ...

Once you have a 3D printer able to build a few objects in a single color, the next logical upgrade is a dual extruder. A dual extruder allows for multiple color prints, and by adding a dissolvable ...

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 ...

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.

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 ...

Most 3D printers are designed to produce plastic parts, such as prototypes, housings for electronics, or decorative objects. Building a working electric machine is far more complicated. Unlike a ...

Those of you that already own a 3D printer or have access to one will already have experienced the mounting costs of purchasing the 3D printing filament required to create and develop your designs and ...

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 ...
