We’re far beyond the heyday of the RepRap project, and the Hackaday tip line isn’t seeing multiple Kickstarters for 3D printers every week. In a way, this is a bit of a loss. The rapid evolution of ...

Filament-based 3D printers are remarkably wasteful. If you buy a kilogram of filament from your favorite supplier, the odds are that it will come wrapped around a plastic spool weighing about 250 ...

Filaments are the building blocks of three-dimensional printing. As the world of 3D printing is becoming more advanced, so are the filaments that are used within the printers. While ABS filaments are ...

A new 2025 review identifies several bulk 3D printer filament options that combine affordability with reliable print quality, addressing growing demand from hobbyists, educational users, and small ...

A rule you can follow and use every time you print.

A Ben Cox, engineer at the Morgridge Institute for Research: 3D printing is a process by which we make a piece layer by layer, and the various forms of 3D printing differ in how they make each layer.

Ordinarily, when using an off-the-shelf 3D printer, it's quite difficult to print a single object that incorporates multiple materials. An experimental new system could make it easier, though, by ...
