STL Volume Model Calculator

This script provides functionality to calculate the volume and surface area of 3D models stored in the STL file format, as well as estimate the weight of the model based on the selected material. It is implemented in Python and supports both binary and ASCII STL files.

Usage

To use the script, navigate to the directory containing volume_calculator.py and your STL file in a terminal, then execute one of the following commands based on your needs:

Volume and Mass Calculation

python volume_calculator.py <filename.stl> volume --material <material_id_or_name> [--unit cm|inch]

Surface Area Calculation

python volume_calculator.py <filename.stl> area

Arguments:

<filename.stl>: Replace with the path to your STL file. <material_id_or_name>: Replace with the ID or name of the material you want to use for mass estimation (see the list of materials above). Options:

--unit: (Optional) Specify the unit for volume calculation. Choices are cm (default) or inch. Examples:

Calculate the volume and mass of torus.stl using ABS material:

python volume_calculator.py torus.stl volume --material ABS

Calculate the surface area of torus.stl:

python volume_calculator.py torus.stl area

Materials Supported

The script comes with an extensive list of 3D printable materials each with its specified density which is used to calculate the mass of the model. The materials included are:

• ABS
• PLA
• 3k CFRP
• Plexiglass
• Alumide
• Aluminum
• Brass
• Bronze
• Copper
• Gold_14K
• Gold_18K
• Polyamide_MJF
• Polyamide_SLS
• Rubber
• Silver
• Steel
• Titanium
• Resin
