Adjusting Layer Times for Resin 3D Printing: A Handy Calculator

If you’re into resin 3D printing, you know that adjusting layer times when changing layer height is crucial for successful prints. But it’s also incredibly annoying. That’s why I’ve created this handy calculator to do the math for you.

Based on the information from this video by 3Dprintingpro, this calculator helps you determine the adjusted slow layer time and regular layer time when you change the layer height.

To use the calculator, simply enter your current slow layer time, current regular layer time, current layer height, and the new layer height you want to use. Then click “Calculate” to get your adjusted layer times.

Here’s the calculator:

The calculator uses the following formula to calculate the adjusted exposure times:

Adjusted Exposure Time = Current Exposure Time - (((1 - (New Layer Height / Current Layer Height)) / 2) * Current Exposure Time)

This formula is used for both the slow layer time and the regular layer time. It calculates the proportional change in layer height, halves this proportion, and subtracts it from the current exposure time to get the adjusted exposure time.

This calculation is based on the assumption that the exposure time is roughly proportional to the layer height. So, if you’re decreasing the layer height, you’ll need less exposure time, and vice versa.

Remember, this calculator is just a starting point. Always monitor your prints and adjust the settings as needed based on the results.

Happy printing!
