What is the impact of building things in layers?

• A. With thinner layers it will take longer to print
• B. It will print faster with thinner layers
• C. Layer thickness has no impact on print time
• D. Layering only affects color accuracy

Answer: (A)

Layer height determines how many individual layers the printer must build to reach the final object height. Using thinner layers means more layers are needed, so the printer has to perform more passes and work longer, making the overall print time longer. The number of layers is roughly the object height divided by the layer thickness, so smaller thickness equals more layers and more time. Thinner layers do improve detail and surface quality, but that comes with the trade-off of longer print times. If you want a faster print, you’d typically choose thicker layers, which reduces the number of layers but reduces resolution. Layer thickness also affects other aspects like surface finish and, in some materials, strength, not just color accuracy.
