How Long Does 3D Printing Take?

The time it takes to complete a 3D print can vary widely depending on several factors. Here are the main factors that influence the duration of a 3D printing job:

Factors Affecting 3D Printing Time

1. Print Size:
   • Larger prints require more material and time to complete than smaller ones.
2. Layer Height:
   • Thinner layers (higher resolution) result in smoother prints but increase the print time. Common layer heights range from 0.1 mm to 0.3 mm.
3. Print Speed:
   • The speed at which the printer moves and extrudes material. Higher speeds reduce print time but can affect print quality.
4. Infill Density:
   • Higher infill density increases print time. Most prints use infill densities between 10% and 20%, but functional parts might require higher densities.
5. Complexity of Design:
   • More complex designs with intricate details or lots of overhangs may take longer due to the need for support structures and slower print speeds to ensure accuracy.
6. Printer Type:
   • Different types of 3D printers (FDM, SLA, SLS, etc.) have different speeds. For example, SLA printers are typically slower than FDM printers due to the curing process of the resin.
7. Material:
   • Some materials print faster than others. For instance, PLA generally prints faster and more easily than flexible materials like TPU.

Estimating Print Time

Here are some general estimates for different types of prints:

• Small, Simple Objects (e.g., a small figurine or part):
  • 1 to 4 hours.
• Medium-sized Objects (e.g., a phone holder or medium-sized model):
  • 4 to 12 hours.
• Large, Complex Objects (e.g., a full-size helmet or detailed model):
  • 12 to 48 hours or more.

Examples

• Small Keychain:
  • Layer height: 0.2 mm
  • Infill: 20%
  • Print time: 1-2 hours
• Medium Vase:
  • Layer height: 0.2 mm
  • Infill: 10%
  • Print time: 6-10 hours
• Large, Detailed Bust:
  • Layer height: 0.1 mm
  • Infill: 20%
  • Print time: 24-48 hours

Tips to Reduce Print Time

• Increase Layer Height: Using a larger layer height can significantly reduce print time at the expense of surface finish quality.
• Optimize Infill Density: Use lower infill density where strength is not critical.
• Adjust Print Speed: Increase the print speed, balancing with acceptable print quality.
• Simplify the Design: Reduce complexity where possible.
• Use Larger Nozzles: For FDM printers, larger nozzle diameters can print faster but with less detail.

Conclusion

The duration of a 3D print is influenced by a combination of factors related to the print’s size, complexity, and the specific settings and capabilities of the 3D printer. While a small, simple print might take just a couple of hours, larger and more complex prints can take a day or more to complete. Adjusting print settings can help manage and optimize the time required for different projects.
