How to Use This Calculator

How the result changes with Layer height (μm)

XY pixel size (μm): Projector/laser XY resolution in micrometers. Consumer DLP ~35-50μm, pro SLA ~25-140μm.
Layer height (μm): Z-axis layer thickness in micrometers. Fine detail: 25-50μm, standard: 50-100μm.
Part length (mm): Part dimension along X axis.
Part width (mm): Part dimension along Y axis.
Part height (mm): Part dimension along Z axis (build direction).

Total layers: Number of sliced layers in the build.
Pixels per layer: Number of XY pixels covering the part footprint per layer.
Total voxels: Total addressable volume elements (pixels x layers).
Min feature XY (mm): Smallest printable feature in the XY plane (~2 pixels wide).
Min feature Z (mm): Smallest printable feature in the Z direction (one layer).
Surface roughness Z (μm Ra): Estimated arithmetic average roughness on vertical surfaces from stair-stepping.
Surface roughness XY (μm Ra): Estimated roughness on horizontal surfaces from pixel resolution.
Voxel volume (mm³): Volume of a single voxel (smallest addressable unit).

Identify Input Parameters
4 parameters
XY pixel size (μm) = 50, Layer height (μm) = 50, Part length (mm) = 40, Part width (mm) = 30 = 5 input(s) provided
Calculate Total layers
Total layers = ceil(partHeightMm / layerHeightMm)
400 = 400
Calculate Min feature XY
Min feature XY = xyPixelMm * 2
0.1 = 0.1
Calculate Pixels per layer
Pixels per layer = pixelsX * pixelsY
480000 = 480000
Calculate Total voxels
Total voxels = pixelsPerLayer * totalLayers
192000000 = 192000000
