About Print Time Estimator
Drop an STL or 3MF file — binary or ASCII — and the tool measures its real geometry: volume via the divergence theorem, surface area, bounding box and non-manifold edges.
With your layer height, line width, perimeters, infill and speed settings it estimates deposited plastic, filament grams and meters, and a print-time range. A volumetric flow check warns you when the hotend, not the XY speed, is the limiting factor. Everything is computed locally — the file never leaves your browser.
