MANUFACTURING – 3D PRINTING (FDM) CALCULATOR
Cooling Speed
A precise tool.
What is the Cooling Speed & How does it work?
Cooling speed in FDM printing determines how quickly a freshly extruded filament solidifies, directly influencing layer adhesion and surface finish.
Higher fan speeds increase convective heat removal, which is beneficial for materials like PLA but can cause warping or delamination in ABS if the temperature gradient becomes too steep.
Balancing print speed, nozzle temperature, and ambient conditions is essential; excessive cooling can lead to poor interlayer bonding, while insufficient cooling results in stringing and loss of detail.
v_c = frac{F_{fan} times V_{print}}{T_{nozzle} – T_{ambient}}
v_c = cooling speed (mm/s)

Frequently Asked Questions
What is the impact of fan speed on cooling in FDM printing?
Higher fan speeds increase convective heat removal, which helps PLA solidify quickly but can cause ABS to warp or delaminate if the temperature gradient becomes too steep.
How does excessive cooling affect FDM prints?
Excessive cooling can lead to poor interlayer bonding, resulting in weak print quality and potential structural issues.
What should I consider when balancing print speed with cooling speed?
You should consider the material properties, ambient conditions, and nozzle temperature to ensure proper solidification without causing defects like warping or delamination.
Can insufficient cooling cause problems in FDM printing?
Yes, insufficient cooling can result in undercured layers, leading to poor surface finish and dimensional inaccuracies.
How does ambient temperature affect the cooling speed in FDM printing?
Higher ambient temperatures require faster cooling speeds to prevent overhangs from warping or delaminating during the print process.
What materials benefit most from controlled cooling speeds in FDM printing?
PLA and other thermoplastics that are prone to warping or delamination benefit significantly from controlled cooling speeds.
How can I adjust the cooling speed for better print quality?
Adjust the fan speed, monitor ambient conditions, and experiment with different nozzle temperatures to find the optimal cooling speed for your specific material and model.
