Solution

Know if a model will print before you start the printer

STL analysis measures your model, slices it with supports on the printer you choose, and turns the result into a risk score where every point has a stated reason.

In short

An STL analysis in 3D Fosil reports dimensions, build volume fit, mesh watertightness, overhang area, support share, print time, filament weight and material cost for a chosen printer.

What you get

Fit check

Compares the model's width, depth and height with your printer's build volume.

Mesh health

Counts open edges so you know whether the mesh is watertight before slicing.

Overhangs and supports

Finds downward faces past the support angle and measures how much filament supports will use.

Time, weight and cost

Uses a real slice of the model for print time and filament, priced per material.

How it works

Drop an STL, 3MF or OBJ file into the analysis page.

Choose printer and material

Pick one of your saved printers and PLA, PETG or ABS.

STL Analysis: common questions

How is the risk score calculated?

The score adds points for specific problems: the model not fitting the build volume, open edges in the mesh, a high share of filament going into supports, and a tall model on a small footprint. Each point is listed with its reason.
