Proposal: Batch Automated 3D Printing with Auto-Ejection

Dear OrcaSlicer Community and Developers,

I’d like to propose a new feature for OrcaSlicer that could significantly enhance its capabilities: Batch Automated 3D Printing with Auto-Ejection Support. This feature aims to streamline the printing of multiple parts by automating the process of printing, ejecting, and preparing for the next print.

Key Features

• Batch Printing Workflow:
  • Allow users to specify the number of prints required.
  • Automatically duplicate and arrange parts on the print bed.
• User-Defined Input Parameters:
  • Model Height Analysis: Use the sliced model height to determine feasibility for auto-ejection.
  • 3D Printer Mode: Adapt movements based on printer type:
    • Core XY: Execute precise lateral ejection movements.
    • Core XZ: Consider vertical eject adjustments.
• Auto-Ejection G-code Integration:
  • Enable users to input custom G-code for bed clearing after each print.
  • Provide pre-configured templates for popular printers (e.g., Ender, Bambu Lab X1C).
• Visual Preview of Auto-Ejection:
  • Include a simulation showing the ejection sequence, so users can validate their setup before initiating a print job.
• Smart Plate Management:
  • Automatically cool or heat the bed as required for safe and effective part removal.
  • Include checks for bed adhesion and material compatibility.
• Failsafes and Triggers:
  • Analyze print settings to ensure successful ejection (e.g., minimum part height, adhesion strength).
  • Abort ejection if risks are detected (e.g., part height too small, risk of damage).

Benefits

• Efficiency: Automates tedious manual tasks, allowing continuous printing without user intervention.
• Scalability: Ideal for producing multiple identical parts or small batch production.
• Compatibility: Expands OrcaSlicer’s utility for advanced users and automation enthusiasts.
• Preview Confidence: Users can test and adjust ejection strategies with visual feedback.

Technical Challenges

• Printer Compatibility: Not all printers support automated part ejection; hardware prerequisites must be defined.
• G-code Complexity: Developing robust and flexible G-code templates for diverse printer models.
• Safety Considerations: Ensuring no damage to parts, printers, or eject mechanisms.

Call to Action

I believe this feature would position OrcaSlicer as the go-to slicer for automated workflows, competing strongly with both proprietary and open-source solutions. If the community supports this idea, we could collaboratively refine the concept and create a roadmap for development.

I look forward to hearing your thoughts and suggestions!

Best regards,
Neckr0ik

Curious - how would the ejection occur, exactly?

My idea on a bedslinger is using the X axis to push the object forward first, then using the toolhead itself just to make a second pass to certify the bed plate is clear, here's something I use already between my prints

; Auto-Extraction GCODE
M140 S45 ; Set bed temperature to 45°C
M190 S45 ; Wait for bed temperature to reach 45°C

; --- Variables ---
{bed_x} = 256 ; Total bed width (X)
{bed_y} = 262.5 ; Total bed depth (Y)
{safe_z} = 40 ; Safe Z height
{center_x} = {{bed_x} / 2} ; Center of the bed on X axis

; Positioning for extraction
G90 ; Set absolute positioning

; --- Start pushing sequence at the left edge ---
G1 Z{safe_z} F1200 ; Move Z to safe height
G1 X40 Y{bed_y} F3000 ; Move to X: 40 (left edge), Y: max (back)
G1 Z1.5 F600 ; Lower Z to 1.5mm
G1 Y0 F1000 ; Push forward (Y min)
G1 Y{bed_y} F3000 ; Return to Y max (back)

; --- Pushing sequence at the center of the bed ---
G1 Z{safe_z} F1200 ; Move Z to safe height
G1 X{center_x} F3000 ; Move to the center of the bed (X axis)
G1 Z1.5 F600 ; Lower Z to 1.5mm
G1 Y0 F1000 ; Push forward (Y min)
G1 Y{bed_y} F3000 ; Return to Y max (back)

; --- Finish extraction ---
G1 Z{safe_z} F1200 ; Move Z to safe height
G1 Y{bed_y} F3000 ; Return to Y max (safe position)
M400 ; Wait for all movements to finish
