75,000+ layers with any Formlabs material

For example: approximately 190 prints using an average height model (39 mm tall), any resin, and 100 µm layer height

600k – 1.9M layers, depending on material and layer height

For example: approximately 1,300 prints using average height models (87 mm tall), Grey Resin V5, and 100 µm layer height
