One-line verdict
High-speed enclosed CoreXY for power users printing engineering filaments like ABS ASA nylon and carbon fiber, but early units require hardware fixes for reliability.
How it compares
- vs Bambu Lab P2S ($550–$800): Plus4 wins on active chamber heating for high-temp filaments like nylon and carbon fiber, P2S wins on multi-color support and out-of-box reliability
- vs Bambu Lab X1 Carbon ($1100–$1400): Plus4 wins on price for active chamber heating capability, X1C wins on Lidar calibration, software maturity, and overall system reliability
- vs Prusa MK4S ($750–$1100): Plus4 wins on print speed and high-temp enclosure performance, MK4S wins on proven long-term reliability and open-source repairability
- vs Creality K2 Combo ($550–$700): Plus4 wins on active chamber heating and high-temp engineering filament support, K2 Combo wins on build volume and multi-color functionality
AI-summarized review themes
Frequently Praised
- Exceptional print quality on PLA PETG ABS and carbon fiber composites
- Fast 600mm/s speeds with smooth surfaces and minimal artifacts after tuning
- Heated chamber up to 65C eliminates warping on high-temp materials
- Fully automatic leveling and calibration minimizes setup tinkering
- Large 305x305x280mm volume handles helmets and multi-part models easily
Frequently Criticized
- Early SSR overheating risks fire hazards needing warranty replacement
- Frequent Z-offset drift and bed leveling issues on high-temp prints
- Hotend failures like heat breaks cracking after hundreds of hours
- Occasional chamber heater and sensor malfunctions require support
- Thick bed heats slowly extending preheat times significantly
Best for
engineering prototypes, functional carbon fiber parts, high-temp ABS ASA printing, serious hobbyist farms
Not for
absolute beginners avoiding tweaks, multi-color printing without add-on box, budget buyers seeking zero maintenance
