The Original Prusa i3 Mk3 is an excellent Fused Filament Fabrication (FFF) 3D Printer and one of the best ready to run consumer-grade 3D printers out there. With a solid frame, easily replaceable and upgradeable parts, and a community to rally around, it's one of the best places to start a 3D printer journey. But even one of the best 3D printers isn't perfect, and here are some of the best upgrades we would add to the Prusa Mk3.

All of the items I've listed will be great purchases, but which ones you buy will often depend on what you want out of the 3D printer — except the MK3s upgrade kit, which should be a mandatory purchase. The upgrade kit is not expensive and comes with everything you need to bring your machine up to the latest Prusa specs. The more reliable filament run-out sensor, the easier maintenance on the X carriage and extruder are well worth the cost.

Other upgrades, such as the three Items from E3D, should all be considered quality of life upgrades, or "set and forget." The Nozzle X lets you print any material without fear of damaging the nozzle such as glow-In-the-dark filament or carbon fiber-filled materials. The Titanium Heatbreak lets you forget about potential heat creep or PLA sticking on the inside and causing a clog. Lastly, the Silicone sock is something that should be there from the beginning, and at such a low cost for three, you'll even have spares.

The only premium purchase is the MMU2s upgrade kit. It's expensive and likely won't be used often. Still, if you want to print in multiple materials or colors, the MMU2s takes the spot of the Palette 2s Pro because of the better integration with the Prusa ecosystem of machine, slicer, and filament.
