Every printer has limits it ships with: the nozzle, bed and chamber temperatures it is built for, the caps set in its firmware, and what its warranty allows. Each page here starts from those limits.

Upgrade options are set out in tables sorted by a neutral column, such as temperature rating or price, never ranked. Every figure cites its source, and every page shows when it was last checked.

The model-by-model 3D printer upgrade wiki.

Start from the machine you own and the material you want to print, find the limit that stops you, and see every route past it: hotends and nozzles, enclosures and chamber heating, firmware and Klipper, beds and build plates, and multi-color systems. Each route comes with its dependencies, its cost and what it means for the warranty.
