What is Heat Soak and Why is it Important?

Heat soak involves preheating the print bed to a specific temperature and maintaining it for a set duration before starting the print. This process allows the bed to reach thermal equilibrium, ensuring consistent heat distribution. For the Bambu P1S, proper heat soak is crucial for materials like PLA, PETG, and ABS, as it prevents first-layer adhesion issues and warping.

Step-by-Step Guide to Heat Soak with Bambu P1S

Follow these steps to master heat soak with your Bambu P1S:

• Step 1: Set the Bed Temperature – Navigate to the Bambu P1S interface and set the bed temperature according to your filament type. For PLA, 60°C is ideal; for PETG, use 70°C; and for ABS, aim for 100°C. (Bambu P1S temperature settings, filament-specific temperatures)


• Step 2: Preheat the Bed – Start preheating and allow the bed to reach the set temperature. This typically takes 2-3 minutes. (Preheating duration, bed temperature stability)


• Step 3: Apply Adhesion Aid – While the bed heats, apply a thin layer of adhesion aid like glue stick, hairspray, or BuildTak. Ensure even coverage for consistent adhesion. (Adhesion aids, bed preparation)


• Step 4: Wait for Heat Soak Completion – Let the bed maintain the temperature for an additional 1-2 minutes to ensure uniform heat distribution. (Heat soak duration, uniform heat distribution)

💡 Note: Avoid rushing the heat soak process, as inadequate heating can lead to poor adhesion and print failures.

Advanced Tips for Perfect Heat Soak

Take your heat soak technique to the next level with these advanced tips:

• Use a Temperature Tower – Print a temperature tower to fine-tune your bed temperature for specific materials. (Temperature tower, material calibration)


• Upgrade Your Bed Surface – Consider using a PEI sheet or textured surface for better adhesion during heat soak. (PEI sheet, bed surface upgrades)


• Monitor Bed Leveling – Ensure your bed is properly leveled before starting the heat soak process. (Bed leveling, print quality)

Common Mistakes to Avoid

Steer clear of these pitfalls to ensure successful heat soak:

• Skipping Preheating – Always preheat the bed to the desired temperature before applying adhesion aids. (Preheating importance, adhesion failure)


• Overheating the Bed – Exceeding recommended temperatures can damage the bed surface or warp prints. (Overheating risks, bed damage)


• Uneven Adhesion Aid Application – Inconsistent application can lead to uneven adhesion and print detachment. (Adhesion aid application, print detachment)

Heat Soak Mastery Checklist

• Set the correct bed temperature for your filament.


• Preheat the bed and wait for thermal equilibrium.


• Apply adhesion aid evenly across the bed surface.


• Allow 1-2 minutes for heat soak completion.


• Ensure proper bed leveling before printing.
