STL to 3MF Converter

stlto3mf is a command line tool written in Rust that merges multiple STL files representing a single object into a single 3MF file. This is especially useful for multi-material 3D printing, saving time and effort when dealing with slicer programs.

Features

• Merge multiple STL files into a single 3MF file.
• Generate a generic 3MF file compatible with any slicer program or 3D viewer that supports the 3MF format.

Requirements

• Rust (for building from source)

Installation

To build from source, you need to have Rust installed. Clone the repository and build the project:

git clone https://github.com/yourusername/stlto3mf.git
cd stlto3mf
cargo run
# or
cargo install --path '.'

The executable will be available in the target/release directory (or in your $PATH)

Usage

stlto3mf [OPTIONS] --output <OUTPUT> [STL_FILES]...

Arguments

• [STL_FILES]...

  List of STL files to merge.

Options

• --output <OUTPUT> Name of a group of STLs in the final .3MF file.

• --name <NAME> Output filename for the 3MF file.

• -h, --help Print help information.

• -V, --version Print version information.

Examples

Basic Usage

Merge multiple STL files into a single 3MF file with a specified output name:

stlto3mf --output final_object --name output.3mf part1.stl part2.stl part3.stl

This command will merge part1.stl, part2.stl, and part3.stl into a single output.3mf file, grouping them under final_object.

Help and Version

To print the help information:

stlto3mf --help

To print the version information:
