Bambu PLA & PETG Filament Calibration Temperature Tower

This temperature tower model is designed to help you calibrate the optimal printing temperature for Bambu PLA and PETG filaments. It features a progressive range of temperatures for both filament types:

• PETG: 220°C - 255°C
• PLA: 190°C - 225°C

The tower incorporates a variety of test features to assess print quality at each temperature setting:

• Overhangs
• Cones
• Fillets
• Horizontal and vertical circles
• Bridging challenges

By analyzing the printed tower, you can identify the temperature that produces the best results in terms of:

• Layer adhesion
• Surface finish
• Stringing
• Bridging accuracy
• Overall dimensional accuracy

This information will help you fine-tune your printer settings for superior results with Bambu PLA and PETG filaments.

How to Add Temperature Changes in Bambu Studio

Slice the Model: Open the 3MF file in your slicer software and proceed with slicing the model.

• Locate Layer for Temperature Change: Navigate to the preview tab within your slicer. Identify layer 55 (or a suitable layer for your desired temperature change) on the preview timeline.
• Insert Custom G-Code: Right-click the "+" icon next to layer 55 and select "Add Custom G-Code" from the menu.
• Implement Temperature Control: A text box will appear for entering G-code. Paste the following code, ensuring removal of the brackets: M109 S
• Set Temperature Value: Replace with the specific temperature you wish to introduce at layer 55.

Layers to add temperature change code:

• 55
• 105
• 155
• 205
• 255
• 305
• 355

Explanation:

• The provided G-code snippet utilizes the M109 command, commonly used in 3D printing to set the extruder temperature.
• By replacing with your desired temperature, this code instructs the printer to adjust the temperature at layer 55.
