PyMFCAD

PyMFCAD is a Python package for rapid design and prototyping of 3D-printed microfluidic devices. It provides a component-based workflow for building reusable parts, assembling devices, routing connections, visualizing results, and generating printer-ready slices.

Key features

Component-based design: Build microfluidic devices from reusable components and subcomponents.
Flexible geometry: Create primitives, complex shapes, polychannels, and Bézier curves.
Pixel/layer precision: Work at printer resolution for high-fidelity fabrication.
Automatic routing: Connect ports with manual or fully automatic routing tools.
Visualization + rendering: Preview designs in 3D before slicing.
Slicing support: Export printer-ready slices (for custom printers only).
Extensible: Add your own component libraries and reusable features.

Typical workflow

Define components (bulk material + negative feature)
Assemble microfluidic device (position and combine subcomponent in a parent component)
Route connections (ports + routing tools)
Visualize and render (inspect in 3D)
Slice and export (generate print files)

Installation

pip install pymfcad
