Here’s an example of why I love 3D printers. 3D printers can replicate virtually any part or product through a process called additive manufacturing, which assembles physical objects by layering a pliable filament or building material. Most consumer 3D printers work with various plastics, but there are printers that work with a wide range of materials including metals, ceramics, composites, wood, and more. In the decade since 3D printers first exploded onto the consumer tech scene, these tools have become much easier to use. I’ve taken the time to test some of the most highly rated and popular 3D printers to highlight the best for new users.
