3D print weight calculator

Attach an STL, OBJ, GLB, 3MF, STEP or STP file and estimate model volume, shell + infill material, filament weight, filament length and print cost.

Browser-side 3D analysisThe model file stays in your browser during calculation. STL/OBJ/GLB/3MF are parsed locally; STEP/STP uses a browser-loaded OpenCascade WASM parser and still keeps the model data local.

Estimate is based on calculated model volume, shell, infill, material density and your price-per-gram range.

STL, OBJ, GLB, 3MF, STEP and STP. Default print model uses ~1.2 mm shell plus the selected infill percentage.
Available materials for the 3D calculator. One material per line in the Choices tab.
3D files are analyzed locally in the browser by default. The original model is not uploaded with the form submission; only the calculation data is saved. STEP/STP support loads the OpenCascade browser parser when needed.
