How to Use Exposure Time Helper
Select your printer LCD screen type (Mono LCD 4K/8K/12K vs Legacy RGB LCD).
Select resin brand and resin color (Clear, Grey, White, Black, Tough).
View recommended base exposure (seconds), bottom exposure (seconds), and lift speed settings.
What is the Exposure Time Helper?
A calibration guide that suggests starting UV cure times based on screen UV power output, resin pigmentation, and layer thickness.
Formula Used
• Estimated Normal Exposure = Base Resin Factor × Color Pigment Multiplier × (Layer Height / 0.05)
• Bottom Exposure = Normal Exposure × 8 to 12
Real-World Example
Standard grey resin on an 8K Mono printer at 0.05mm height: 2.2s normal exposure, 28s bottom layer (6 layers), 60 mm/min lift speed.
Accuracy and Limitations
Ambient temperature below 20°C (68°F) requires increasing exposure times by 10%–20%. Always run a Cones of Calibration test.
Who It Is For
Beginner and advanced resin 3D printer users dialing in new resin bottles.
Frequently Asked Questions
What is normal exposure time for modern Mono LCD resin printers?
Modern Monochrome LCD printers typically require 1.8 to 2.8 seconds per normal layer (at 0.05mm layer height), and 25 to 35 seconds for bottom adhesion layers.
