What is the Optimal Temperature for 3D Printing?

1. Why does Temperature Matter?

• Temperature plays an important role in making resin more reactive, and makes it require less energy to be cured.
• Hot resin is usually less viscous and more reactive compared to cold resin.
• Exposure time for a resin will increase or decrease depending on the weather.

2. Optimal Temperature for Resin 3D Printing

• Most resins perform best above 24°C, and will begin to fail below 20°C
• Ideal temperature range is 24°C-30°C (75°F-86°F) 
• If ambient temperature falls between 18°C-24°C (65°F-75°F), exposure time should be increased by 20%
• If ambient temperature is below 18°C ( 65°F), printing is not recommended. If you still wish to print, make sure to heat the resin. 

If heating the environment is not possible, we suggest installing a heater to the printer. Please check out this post for suggestions. When installing a heater or a thermostat, make sure it maintains an optimal temperature. Fluctuating temperature will result in printing failures.
