What Qidi is for
Engineering filaments. Every current model has an actively heated chamber and a 350 °C or hotter nozzle, which is the entry ticket for nylon, PC, PPA and their fibre blends; see PA-CF. Bambu offers this only in the H2 series, Creality only in the K2 Plus. If your parts are PLA and PETG, a Qidi is over-specified and a Bambu or Creality with better software is the easier life.
Pick by size
- Desk, most parts: Q2 or Q2 Combo. See the Q1 Pro and Q2 page.
- Helmets and enclosures: Plus 4 or Plus 5 Combo. See the Plus 4 page.
- Large functional parts: Max 4.
Trade-offs
- Qidi Slicer and firmware are less polished than Bambu Studio; Klipper root access partly compensates.
- Chamber heaters add power draw and a warm-up wait.
- Spares depth is improving; see Qidi upgrades.
