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 ...

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 ...

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 ...

What type of 3D printing filament should you buy? Best answer: Polylactic Acid (PLA) is the best all-round filament for making models, especially if you're going to finishing them. It's forgiving, ...

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 ...
