Important Note
This is a rough estimate. Actual print time depends on model geometry, travel moves, retraction settings, acceleration, and many other factors. Your slicer provides a much more accurate estimate for specific models.
What Affects 3D Print Time?
Print time depends on many interrelated factors. Understanding these helps you optimize your printing workflow.
Primary Factors
- Layer Height: The biggest single factor. Halving layer height roughly doubles print time.
- Print Speed: Faster is quicker, but too fast reduces quality. Limited by volumetric flow.
- Model Size: Larger models = more material = longer time (scales roughly with volume).
- Infill Percentage: More infill = more material to deposit per layer.
Secondary Factors
- Wall Count: More walls = more perimeter toolpath = longer per layer.
- Acceleration: Higher acceleration reaches target speed faster on short segments.
- Travel Speed: Non-printing moves between features.
- Retraction: Each retraction adds ~0.5-1 second.
- Supports: Additional structures that need to be printed.
Speed Optimization Tips
- Use 0.24-0.28mm layers for non-visual parts (40-60% time savings vs 0.12mm)
- Use a 0.6mm nozzle for larger prints (significant speed increase)
- Reduce infill to 10-15% for decorative items
- Enable adaptive layer height in your slicer for mixed detail levels
