STLTIME

A small utility for estimating 3D printing time before you open the slicer.

Drop in an STL and get a realistic print-time estimate in seconds, based on your printer profile and a little geometry.

What it is

A tiny web tool that answers one question: how long will this take to print? It reads the mesh, estimates volume and travel, and gives you a number before you commit to slicing.

Software

Everything runs in the browser. Parsing happens in a worker so large files don't freeze the page.
