Step by Step Instructions for Undertaking the Task

BEFORE STARTING - CRITICAL SAFETY REQUIREMENTS

1. PRE-OPERATION SAFETY CHECKS (MANDATORY - DO NOT SKIP)

  1. Sign in to the equipment log book (record name, date, time, operation type)

  2. Visual inspection of laser safety windows:
    • Check front laser safety window (green-tinted) for cracks, chips, or damage
    • Check all side panels and top cover for damage
    • If ANY damage found: DO NOT USE - lock out and report to supervisor
  3. Test door interlocks (CRITICAL):
    • Power on the equipment
    • Navigate to settings menu and initiate a test print or laser operation
    • Slowly open the front door - laser/print head MUST stop immediately
    • Close door and repeat test with top glass cover
    • If interlocks fail: DO NOT USE - lock out and report immediately
  4. Emergency stop test:
    • Press the red emergency stop button
    • Verify all motion stops and alarm sounds
    • Reset emergency stop by twisting clockwise
  5. Verify local exhaust ventilation (LEV):
    • Check exhaust ducting is connected
    • Turn on LEV/air purifier
    • Verify airflow (use tissue test if needed)
  6. Check fire extinguisher:
    • COâ‚‚ or dry powder extinguisher present within 5 metres
    • Check pressure gauge in green zone
    • Check clear access path to extinguisher
  7. Clear work area:
    • Remove all flammable materials from vicinity (papers, solvents, etc.)
    • Ensure clear egress path for emergency evacuation
    • Remove clutter around equipment

2. MATERIAL PREPARATION AND APPROVAL

  1. Check material is approved:
    • Consult approved materials list
    • PROHIBITED: PVC, polycarbonate, materials containing chlorine or halogens
    • If material not on approved list: seek approval from supervisor before use
  2. Review material Safety Data Sheet (SDS):
    • Check for hazardous decomposition products
    • Note any special ventilation or PPE requirements
    • Confirm fire hazards and extinguishing methods
  3. Prepare material:
    • Ensure material is clean and dry
    • Check material dimensions fit within build volume (350 × 320 × 325 mm for 3D printing, 310 × 270 mm for laser engraving with 10W module)
    • For laser operations: ensure material is flat and securely positioned

3. EQUIPMENT STARTUP

  1. Power on the Bambu H2D (if not already on from safety checks)
  2. Allow equipment to complete startup sequence and homing
  3. Check touchscreen display for any error messages
  4. Verify network connection (if remote monitoring to be used)
  5. Start LEV/air purifier system

4. PREPARE JOB FILE

  1. Open Bambu Studio or Bambu Suite software on computer
  2. Import or create your design file
  3. For 3D printing:
    • Select material type and printer settings
    • Configure support structures if needed
    • Slice the model and preview toolpaths
    • Check estimated print time and material usage
  4. For laser engraving/cutting:
    • Use BirdsEye camera to align material on bed
    • Set laser power and speed for material type (consult manufacturer guidelines)
    • Configure air assist settings
    • Preview laser path
    • Verify material will not extend outside safe area
  5. Send job file to printer via network or USB

5. LOAD MATERIAL

  1. Open front door (equipment should be idle, not during operation)
  2. For 3D printing:
    • Clean build plate with IPA if needed
    • Install appropriate build plate (textured PEI, smooth PEI, etc.)
    • Load filament spools into AMS (if using multi-material)
    • Verify filament type matches job requirements
  3. For laser operations:
    • Remove build plate if necessary
    • Position material on bed using alignment guides
    • Use BirdsEye camera to verify material position
    • Ensure material is flat and won’t curl during processing
    • Verify material is within safe operating area
  4. Close front door securely - ensure door clicks closed

    • Listen for unusual sounds
    • Watch for excessive smoke or fumes
    • Verify material not moving or curling
  6. During laser operations - MANDATORY ATTENDANCE:
    • You MUST remain within visual line of sight OR monitor via camera continuously
    • Never leave the room during laser cutting/engraving
    • Watch for signs of fire (flames, excessive smoke, burning smell)
    • Keep emergency stop and fire extinguisher within reach
    • If you must leave for any reason: STOP the laser operation first
  7. During 3D printing operations:
    • Check periodically for print failures
    • Can be left unattended if print-only mode (no laser)
    • Camera monitoring recommended for long prints

7. COMPLETION AND SHUTDOWN

  1. Wait for equipment to signal job complete

  2. Allow hot components to cool:
    • Nozzle: can reach 350°C - wait minimum 10 minutes
    • Chamber: can reach 65°C - wait 5 minutes
    • Build plate: wait until below 40°C (touchscreen displays temperature)

  3. Open front door carefully (watch for residual heat)

  4. Remove completed work:
    • Wear heat-resistant gloves if components still warm
    • For 3D prints: allow to cool on plate before removal
    • For laser work: carefully remove material (may have sharp edges)
    • Place in designated area for cooling/collection
  5. Clean work area (see cleanup section below)
  6. Turn off LEV/air purifier (after ensuring adequate ventilation time)
  7. If last user of the day: power down equipment via touchscreen menu
  8. Sign out in equipment log book (record time, any issues)
