The model-by-model 3D printer upgrade wiki

What each Bambu Lab printer can print stock, where its nozzle, bed and chamber limits sit, and which upgrades help with engineering filaments.

What a Voron is, what it prints in a 50 to 60 °C chamber, where its limits sit, and which hotend and chamber upgrades fit for engineering materials.

What caps a 3D printer's nozzle, bed and chamber temperatures, part by part, and what has to change before you can print hotter materials.

How to pick a hotend for nylon, PC and PEEK: all-metal vs PTFE-lined, heat breaks, sensors, heaters, and every 400 to 500 °C hotend compared.

How chamber heater retrofits work, which materials need one, the risks to motors and electronics, and every commercial retrofit kit side by side.

Upgrade a 3D printer in the order your next material needs: enclosure, bed, hardened nozzle, hotend, then chamber heat. With a filament-by-filament chart.

How multi-color 3D printing works with one nozzle, two nozzles, IDEX or a toolchanger, and how each handles purge waste and mixed materials.

A dual nozzle 3D printer has two hotends on one toolhead. What it prints, how it compares with an AMS or MMU, and which printers have one, with prices.

How a 3D printer toolchanger docks, parks and picks up whole toolheads, how many toolheads each system takes, and the main printers and DIY kits.

What Klipper macros are, what they automate, which commands Klipper and Mainsail or Fluidd provide by default, and the macros most printers run.

Most 3D printers have a 1-year US warranty, or 2 years for Bambu Lab from Bambu Store US. Eight brands compared: parts, extensions and claim routes.
