Key strengths
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
The Qidi Tech Plus4, released September 2024, was Qidi's best-selling prosumer printer. Its 305×305×280 mm build volume — larger than the Bambu X1C's 256×256 mm — combined with active 65°C chamber heating and a 370°C bimetal hotend made it one of the most capable enclosed printers under $700. Nominated for Desktop FFF 3D Printer of the Year 2024. Qidi has discontinued it in favour of the Plus5, which offers an 18% larger build volume, a more powerful chamber heater, and loadcell leveling.
The Plus5 is the better purchase — it has an 18% larger build volume (320×320×300 vs 305×305×280 mm), a 550 W third-generation chamber heater, loadcell leveling, and H12 HEPA filtration for $749. Chamber temperature (65°C), hotend temperature (370°C), and top speed (600 mm/s) are unchanged, so a Plus4 at a significant clearance discount remains a capable printer for engineering filaments.
The Plus4 ($699) has a larger build volume than the X1C (305×305 vs 256×256 mm) and active 65°C chamber heating at a lower price. The X1C wins on ecosystem: Bambu Studio is more polished, the AMS multicolor system is more mature, and LiDAR-based print monitoring is a genuine differentiator for unattended printing. If build volume is your priority, the Plus4 is hard to beat at the price. If ecosystem quality and reliability matter more, the X1C justifies its premium.
Yes — it is one of the best prosumer options for carbon-fiber composites. The 370°C bimetal hotend, 65°C active chamber, and available hardened steel nozzle options make it well-suited for PA-CF, PET-CF, and even PPS-CF. Use a hardened steel or ruby nozzle for abrasive filaments — the stock brass nozzle will wear quickly.
The Plus4 has a larger build volume (305×305×280 mm vs 270×270×256 mm) and costs $200 more ($699 vs $499). For most users, the Q2 is the better value. The Plus4 makes sense if you specifically need the extra print area or are running high-volume production where the larger bed matters.
