3D Printer Safety Precautions

Operating a 3D printer involves potential risks. Please follow these precautions to ensure a safe and enjoyable experience:

Environment and Ventilation

• Location: Place the printer in a well-ventilated area.
• Ventilation: Use proper ventilation to remove fumes.
• Fire prevention: Keep a fire extinguisher readily available.

Printing Process

• Monitor printing: Don't leave the printer unattended.
• Material handling: Use caution when handling hot filament and resin
• Post-processing: Follow proper procedures for post-processing.

Additional Tips

• Read the manual:Thoroughly read and understand.
• Use recommended materials: Stick to materials recommended.
• Maintain your printer: Regularly clean and maintain.
• Stay informed: Keep yourself updated on safety best practices.

Remember, safety is paramount. By following these precautions, you can minimize risks and enjoy a safe and successful printing experience.

Design Rules

Design Rules for 3D Printing

Design rules for 3D printing are guidelines that ensure your model can be successfully printed on a particular 3D printer. They take into account the limitations of the printing process, such as the minimum layer thickness, the maximum overhang angle, and the supported resolution.

1. Bridging:

   • Unsupported horizontal spans.
   • Minimize length, use thicker walls for longer spans.
   • Avoid thin, long bridges to prevent sagging or breakage.
   • Consider redesigning to eliminate bridging if possible.







2. Overhang:

   • Jutting sections without underlying support.
   • Limit angles to avoid support structures.
   • Typical FDM limit is around 45 degrees.
   • Use support structures or adjust angles for complex overhangs.







3. Angle:

   • Angle between vertical surface and horizontal plane.
   • Consider minimum angles for features like holes and slots.
   • Steeper angles might require support, impacting print time and quality.
   • Adjust angles or redesign features for printability.







4. Surface Finish:

   • Quality and smoothness of the printed part's exterior.
   • Layer lines are inherent, affecting surface finish.
   • Use higher resolutions for smoother surfaces (increases print time).
   • Optimize for post-processing techniques like sanding or smoothing if needed.







5. Dimension and Wall Thickness:

   • Maintain minimum wall thickness based on material and printer.
   • Too thin walls are weak, excessively thick walls waste material and time.







6. Dimension:

   • Ensure dimensions fit within the printer's build volume.
   • Find the balance between strength, printability, and material efficiency.

Conclusions from the Group Assignment

• Gained a comprehensive understanding of additive vs. subtractive manufacturing, including principles, processes, equipment, achievable complexity, producible features, material suitability, and finishing requirements.
• Explored the advantages and disadvantages of FDM (Fused Deposition Modeling) and various materials used with it.
• Familiarized with the features and operation of the Fracktal Works Julia Advanced 3D printer, including control panel functionalities.
• Successfully tested design rules by printing components and the 3Dbenchy model using PLA filament, comparing printed objects with reference dimensions.
• Learned the process of generating G-code for 3D printing using Fracktory slicing software, including loading STL files, setting parameters, and generating G-code for each object.
• Gained practical experience in setting up the 3D printer, including bed calibration, temperature control, flow rate and feed rate adjustment, and filament extrusion.

Overall, the group assignment provided valuable hands-on experience with 3D printing technology, allowing us to understand the process, experiment with different functionalities, and gain insights into the capabilities and limitations of our specific 3D printer.
