Malyan M150 - User Manual

The Malyan M150 is a desktop 3D printer designed for users to experience 3D printing with ease and reliability. This manual provides a comprehensive guide to its first run, covering setup, operation, and essential maintenance tips to ensure optimal print quality and user safety.

Function Description:

The Malyan M150 is a Fused Deposition Modeling (FDM) 3D printer that creates three-dimensional objects by extruding heated thermoplastic material layer by layer onto a build platform. It is designed for both beginners and experienced users, offering a straightforward interface and robust construction. The printer's core function involves taking a digital 3D model (typically in G-code format from an SD card), heating the filament to its melting point, and then precisely depositing it according to the model's specifications. The M150 features a sturdy frame, an extruder assembly, a heated build platform, and an external control box with an LCD screen for user interaction. It supports common filament types like PLA and ABS, making it versatile for various printing needs, from prototyping to creating functional parts and artistic models.

Important Technical Specifications:

While specific detailed technical specifications like build volume, print speed, and nozzle diameter are not explicitly listed in the provided pages, the manual highlights several key operational aspects:

• Temperature Generation: The Malyan M150 generates high temperatures during operation, particularly around the extruder and the heated build platform. The manual emphasizes allowing sufficient time for the machine to cool down after use to prevent burns. The extruder can reach temperatures of approximately 220°C when heating for PLA.
• Moving Parts: The printer incorporates moving parts (e.g., X, Y, and Z axes, extruder mechanism) that can cause injury if not handled carefully. Users are advised to keep hands clear during operation.
• Electrostatic Discharge (ESD) Sensitivity: The M150 is sensitive to ESD. Users should ground themselves by touching a grounded object before operating or servicing the printer to prevent damage to electronic components.
• Power Supply: The printer uses an external power supply brick. It is crucial not to stack anything on this brick as it can get very hot and potentially fail if insulated.
• Filament Compatibility: The printer supports PLA and ABS filaments, with specific preheat settings available for each.
• Control Interface: The M150 features an LCD screen and a single black aluminum button for navigation and selection. This button can be turned to scroll through menus and pushed to confirm selections.
• Data Input: Prints are loaded from a Micro SD card, which is inserted into a dedicated slot on the control box.

Usage Features:

The Malyan M150 is designed for user-friendly operation, guided by its LCD interface and intuitive controls.

• Initial Setup: The first run experience guides users through essential steps:
  • Unboxing and Hardware Setup: This includes bolting the extruder in place, mounting the filament spool, and connecting the power supply.
  • Power On: Upon powering on, the LCD screen displays the MALYAN logo, indicating readiness for initial setup.
  • Navigation: A single black aluminum button allows users to navigate menus (by turning) and make selections (by pushing).
• Platform Leveling: This is a critical step for print quality.
  • Auto Home: Users navigate to "Prepare" -> "Auto home" to move the extruder to the left bottom side of the printer.
  • Disable Steppers: By navigating to "Control" -> "Disable steppers," power is removed from the motors, allowing manual movement of the extruder along the X-axis and the printing platform along the Y-axis.
  • Manual Adjustment: Users manually move the extruder to different positions over the build platform and adjust the spacing between the nozzle and platform using four knobs located underneath the platform.
  • Spacing Reference: The ideal spacing is approximately the thickness of an A4 paper (0.12 mm). A sticky note can also be used as a reference.
  • Knob Functionality: Tightening the knobs (turning right) moves the build plate away from the nozzle, while loosening them (turning left) moves it closer.
  • Visual Guide: The manual provides visual examples of correct and incorrect nozzle heights, illustrating "NOZZLE TOO HIGH" (small contact area, raft detachment), "OK" (filament pushed slightly into the bed for maximum contact), and "NOZZLE TOO LOW" (insufficient clearance, potential damage to extruder or bed).
• Filament Loading:
  • Preparation: The filament tip should be cut as sharp as possible.
  • Preheat: Users navigate to "Prepare" -> "Preheat PLA" (or ABS) to heat the extruder to the target temperature.
  • Extruder Access: The extruder spring lever must be pushed down to open the filament route.
  • Loading: Navigate to "Extruder" -> "Extr.position" and turn the black button clockwise to load the filament.
  • Filament Path: Ensure the filament loads from the upper side of the spool to prevent jams.
  • Completion: Stop twisting the button once plastic starts extruding from the nozzle.
  • Safety: Users are warned not to touch the hot extruder.
• First Print:
  • SD Card: Ensure the Micro SD card is inserted into the control box.
  • Menu Selection: Navigate to the "Print from SD" menu and select one of the pre-loaded prints.

Maintenance Features:

The manual implicitly suggests several maintenance practices through its safety and operational guidelines.

• Cooling Down: Always allow the Malyan M150 to cool down after operation before attempting any servicing or touching hot parts.
• Cleanliness: After extruding plastic, wait for it to cool and then remove it from the nozzle. This prevents newly extruded plastic from sticking to the nozzle instead of the build platform.
• Platform Leveling: Regular platform leveling is crucial for consistent print quality. If prints are not sticking or the masking tape is tearing, re-leveling the platform is recommended.
• Power Disconnection: When opening the Malyan M150 for service, ensure the power supply is turned off and the cord is disconnected to prevent electrical hazards and ESD damage.
• Ventilation: Always use the duplicator in an open, well-ventilated area to mitigate irritating vapors/fumes produced during operation.
• Unattended Operation: Do not leave the duplicator unattended during operation, implying a need for supervision to address potential issues promptly.
• Filament Handling: Properly cutting the filament tip and ensuring it loads smoothly from the spool's upper side helps prevent jams, which can be a common maintenance issue.
• Support Contact: If issues arise that cannot be resolved through the guide or troubleshooting page, users are advised to contact tech support at support@malyansys.com.
