Temperature Tower G-code Analysis Report

Objective

The objective of this document is to detail the methodology for analyzing the results of a temperature tower G-code file after printing. The analysis will involve inspecting various blocks of the temperature tower for common print defects and issues, and determining the optimal extrusion temperature for a given filament. This process will help identify the most suitable printing temperature to ensure optimal performance for subsequent prints, minimize defects, and maximize print quality.

Methodology

1. Print the Temperature Tower G-code

• Action: Begin by printing the provided temperature tower G-code attached.
• Conditions: Ensure the printer is properly calibrated, including bed leveling and nozzle alignment. Verify that the filament being used is dry and that the nozzle is clean and unobstructed. A blocked nozzle or damp filament will lead to inaccurate results and poor print quality.

2. Inspection of Printed Blocks

Once the print is complete, thoroughly examine the printed temperature tower for common defects and issues that could arise at varying temperatures. 

3. Identification of the Most Suitable Temperature

• Analysis: After thoroughly inspecting each block, identify the layer or block with the most consistent and acceptable print quality. This layer should show minimal defects such as under-extrusion, over-extrusion, stringing, or surface imperfections.

• Optimal Temperature Selection: The temperature of the layer with the best quality (i.e., well-defined features, no defects, and consistent extrusion) should be used as the ideal print temperature for the filament in question. This temperature is the one most likely to produce reliable results when slicing future prints with the same filament. Upon thorough evaluation, it becomes evident that a printing temperature of 180°C effectively mitigates stringing. When considering the model's overhanging features, a slightly elevated temperature of 185°C emerges as the optimal choice. After weighing both stringing and overhanging considerations, the optimal temperature for the red model is determined to be 185°C.

  

4. Temperature Range Considerations

• Too Low a Temperature: If the temperature is set too low, the filament may not flow adequately, leading to under-extrusion, weak layer bonding, and inconsistent print quality. Stringing and poor adhesion are common in these conditions.
  

5. Repeat Testing with Alternative Filament or Printer (If Necessary)

If results are inconclusive or if multiple defects persist despite temperature adjustments, repeat the temperature tower test using a different filament or on a different printer. This will allow for cross-validation and ensure that results are consistent and reliable under varying conditions.

Additional Precautions

• Nozzle Blockage: Before starting the print, ensure the nozzle is clear. A partially blocked nozzle can lead to inconsistent extrusion, skewing the results of the temperature test. If the nozzle is clogged, run a purge or cleaning cycle before printing.

• Filament Condition: Filament must be dry for accurate results. Damp filament will absorb moisture from the air, leading to inconsistent extrusion, poor adhesion, and issues such as popping or bubbling during printing. Always store filament in a dry environment and dry it before use if necessary.

Conclusion

The temperature tower test serves as a vital tool for identifying the optimal printing temperature for a given filament. By inspecting each block for defects such as under-extrusion, over-extrusion, stringing, and surface quality, one can fine-tune the printing parameters for improved performance. After determining the most suitable temperature, subsequent prints should exhibit better adhesion, fewer defects, and a more polished final result. Repeating the test with a different filament or printer can help verify the findings and further refine the process.
