# QIDI Plus4 3D Printer (Plus4)

**Category**: 3d-printers | **Price**: ~$650–$800 | **Reviews referenced**: 500
**Last updated**: 2026-04-19
## 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 ABS/ASA/nylon/CF, P2S wins on out-of-box reliability and AMS multi-color ecosystem
- vs Bambu Lab X1 Carbon ($1100–$1400): Plus4 wins on price and active chamber temperature for engineering filaments, X1C wins on software maturity, LiDAR calibration, and print consistency
- vs Creality K2 Combo ($550–$700): Plus4 wins on high-temp chamber control for engineering materials, K2 Combo wins on build volume and native multi-color support
- vs Prusa MK4S ($750–$1100): Plus4 wins on print speed and active chamber heating, MK4S wins on reliability track record and open-source repairability

## 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
