Introduction

1.1 Product Overview

The X2D is an intelligent 3D printer based on Fused Deposition Modeling (FDM) technology. This model features an innovative dual-extruder system with two separately designed extruders: the auxiliary extruder provides strong thrust to support long-distance filament feeding, while reducing the toolhead load and improving motion performance. It maintains a compact size while ensuring ample print area. The dual hotend design significantly enhances material change efficiency and reduces filament waste.

The X2D also offers the following features to provide a smarter printing experience, making your creativity more efficient and diverse.

• Smooth user experience: The 5-inch touchscreen and second-generation UI provide smoother interaction, while the quick-release hotend design makes routine maintenance and replacement easier.
• Stable support for engineering materials: With a nozzle temperature of up to 300 ℃, a heatbed temperature of up to 120 ℃, and an adaptive airflow system that actively heats the chamber up to 65 ℃, the printer reliably supports a wide range of printing needs, from basic to engineering-grade filaments.
• Intelligent detection and comprehensive calibration: The self-developed extruder motor works with the filament buffer to provide dual filament-tangle detection, while multiple cameras and sensors enable a wide range of smart detection and calibration features.

When used with the Automatic Material System (AMS), it further enhances printing intelligence and ease of use:

• AMS 2 Pro: supports RFID filament sync, automatic multi-color/multi-material changing, and smart drying. Enhances multi-material printing and filament management for a smarter, more convenient, and improved printing experience.
• AMS HT: specialized for high-temperature filaments, the AMS HT supports RFID filament sync, automatic multi-color/multi-material changing, and smart drying, meeting the demands of engineering-grade and professional printing.

Optional upgrade accessories can be used to further improve printing automation and reduce manual operations:

• Filament track switch: supports any mapping between AMS and the two hotends, allowing flexible delivery of filament from AMS to any target hotend, avoiding manual intervention in filament-saving mode.
• TPU feed assist module: allows filament to be fed directly through the module’s inlet while the printer remains enclosed, simplifying TPU print preparation and loading while reducing feeding resistance regardless of spool placement.

1.2 Printer Component Introduction

1.2.1 Printer

1. Filament cutter stopper: Inserts into the toolhead to activate the left and right filament cutters to cut the filaments.
2. Purge wiper: Comprises the purge wiper part and nozzle wiping pad. It cleans and collects excess extruded filament to keep the print surface clean and smooth.
3. Toolhead: Contains the main extruder. It precisely extrudes and heats filament, depositing melted filament layer by layer on the build plate.
4. USB port: Insert a USB drive to print model files offline and store recordings and timelapse files.
5. Air filter: Air inside the chamber passes through an activated carbon filter before being vented, helping reduce particle and odor emissions.
6. Adaptive airflow switching unit: In strong cooling mode, it draws in external cool air to lower the printing environment temperature. In heating mode, it works with the air filter to form an internal air circulation.

1. Touchscreen: Displays printing parameters and controls the printer.
2. Live view camera*: Monitors print progress in real time and is used for timelapse recording and AI vision detection.
3. Circulation mode indicator: Automatically switches based on the air management mode without manual adjustment.
4. Chamber heater unit: In heating mode, it raises and maintains the chamber temperature. In strong cooling mode, it draws external cool air to lower the printing environment temperature.
5. Heatbed: Heats the print surface to ensure stable adhesion of printed layers to the build plate, preventing warping or detachment.
6. Top glass cover: Allows observation of print progress during printing. It provides good sealing and safety and can also be used to place AMS.
7. Side window: Allows observation of print progress from both left and right sides during printing.
8. Front door: Keeps the printer enclosed and helps maintain chamber temperature during high-temperature printing. It also allows observation of print progress.
9. External air intake (lift handle): In strong cooling mode, it draws in external air through the intake to lower the chamber temperature. Use this position to lift the printer for safe handling.

1. Belt tensioner: Adjusts and monitors belt tension. It sends data to the system to ensure printing accuracy and motion stability.
2. Spool holder base: Secures the spool holder to allow placement of an external spool.
3. Power socket and switch: Connect the printer to an AC outlet using the included power cord. Turn on the switch to power the printer.
4. Main extruder PTFE tube bracket: Filament enters the printer through this port and moves to the toolhead’s main hotend.
5. Auxiliary extruder PTFE tube bracket: Filament enters the auxiliary extruder through this port and is then pushed to the toolhead’s auxiliary hotend.
6. Auxiliary extruder: Independently extrudes filament for the auxiliary hotend, pushing filament from the filament buffer to the toolhead.
7. Bambu Bus port 6-pin: Connect AMS devices and external exhaust fans to the printer using the included Bambu Bus cable 6-pin to ensure proper communication.
8. Filament buffer: Reduces tension fluctuations during filament load to ensure smooth feeding.
   • The top includes two Bambu Bus ports 6-pin for data transmission to the AMS and external exhaust fan.
   • The left side has two filament inlets to connect the AMS and the external spool for filament feeding. The upper inlet transports filament to the main hotend, the lower inlet to the auxiliary hotend.
9. Purge chute: Connects to the printer’s internal purge wiper, allowing waste material created during printing to be discharged from the chamber.
10. Ventilation holes: Assist in expelling hot air from the chamber during strong cooling mode.
11. Exhaust fan: Installed on the printer’s back panel, it contains a filter that cleans the internal hot air before exhausting it from the chamber.

1.2.2 Toolhead

1. Main hotend toolhead filament inlet: The filament enters the main extruder and main hotend through this inlet.
2. Main extruder: Grips and pushes filament into the main hotend. Precisely controls filament extrusion and retraction length.
3. Toolhead front cover: Protects the front of the toolhead to prevent dust or debris entry.
4. Part cooling fan: Directs cooling airflow near the hotend nozzle to quickly cool the printed layers.
5. Main hotend: Heats and melts the filament, then extrudes it through the nozzle.
6. Auxiliary hotend toolhead filament inlet: Filament enters the auxiliary extruder through this inlet and is then pushed to the auxiliary hotend.
7. Filament cutter lever: During the unloading process, it drives the left/right filament cutter to cut the filament for the corresponding hotend.
8. Cooling fan for hotend: Stabilizes hotend temperature to prevent clogging caused by overheating.
9. Toolhead camera: Used for motion accuracy calibration, high-precision nozzle offset calibration, and build plate identification code recognition.
10. Auxiliary hotend: Heats and melts filament, then extrudes it through the nozzle. It moves up and down with the nozzle switching lever to switch between the two hotends.
11. Main extruder gear: Made of hardened steel, including drive and driven wheels. Precisely pushes the filament under the drive of the extruder motor.
12. Flow blocker: A black flap located below the nozzle that prevents molten filament inside the idle nozzle from dripping onto the model or build plate.
