The Best 3D Printer

What can you make with a 3D printer? Almost anything you want—from vases to GoPro mounts to phone cases—provided you don’t mind that it’s made out of plastic. Whether you’re a tinkerer interested in prototyping or a tabletop-gaming enthusiast seeking to expand your arsenal of miniatures, a 3D printer might be the manufacturing tool you need. We recommend the Prusa Mini+ printer because it’s the most reliable printer we’ve tested, and we find it to be an especially good value at $400 or so. It’s also easy to use and relatively inexpensive to operate.

The consistency and the thoughtfully chosen, repairable parts of the Prusa Mini+ will please more advanced users who need a dependable 3D-printing machine. It’s also a bargain, with unusual features at this price such as a large, 7-by-7-by-7-inch printing area (also known as the print volume, or the total space you can print within) and a color display, as well as 24/7 customer support. Prusa printers are the quietest models we’ve tested, too, and they’re compatible with a wide range of plastic types.

The Prusa i3 MK3S+ is a worthy upgrade from the Mini+ for its 9.9-by-8.3-by-8.3-inch printing area, more stable z-axis, and better extruder. It comes with parts that are likely to last longer (though no color screen as on the Mini+) and an upgraded motherboard that can better detect and correct errors while the machine is printing. Its setup is also faster and easier than that of the Mini+.

If you’re a total beginner who doesn’t want to invest too much, or if you’re looking for a printer that’s safer for children to use (similar machines are advertised for kids as young as 8), the Monoprice MP Cadet might be a better option. In our testing, it consistently turned out flawless (though less detailed) prints as long as the designs weren’t too complex. It has a small, desk-friendly footprint. It’s also less than half the price of the Prusa Mini+, but it doesn’t offer as many features or produce the same level of detail, and it has a smaller, 3.9-by-4.1-by-3.9-inch print volume.

If you’re trying to print a sci-fi helmet or custom shelving brackets, a larger printer allows you to make the entire part in one shot rather than splitting it into smaller components and gluing them together. The print bed of the Artillery Sidewinder X2, an 11.8-inch square with a height of 15.7 inches, gives you a lot more room for bigger jobs. This model also offers easy setup and an intuitive menu, and in our tests it produced fantastic prints.
