PyMFCAD: v0.5.0

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.

Version Information:

0.4.2 -> 0.5.0 (2026-09-03)

Replaced slicer/print file generation with new workflow utilizing Workspaces. For more details see slicing section of documentation.

Breaking Changes

• Component's no longer accept position parameter. Use translate() instead. (#55)
• Membrane Settings no longer directly accepts exposure parameters (such as exposure times), now accepts ExposureSettings object (#59)
• Devices have been completely removed. Printer resolution is now handled by slicer (#48)
• Slicer has been renamed PrintFileGenerator (#62)
• Slicer.make_print_file() has been renamed .run()
• Slicer settings object has been removed. PrintFileGenerator now directly accepts parameters. (#56)
• PrintFileGen now accepts either a single component or a Workspace (advanced component placement)
• Printer class now need default positional settings
• Printer class now accepts stitching settings
• LightEngine class now needs default exposure settings

New Features

• Added scale function to shape (#52)
• Added single parameter shape resize (#53)
• Added libraries for printers and resins (#58)
• PrintFileGen now handles embedded and stitching internally

Bug Fixes

• Removed unnessicary init saving args (#35)
• Regional settings not impacting subcomponents (#43)
• Channel rounding in fractional routing broken (#63)
• Subcomponets of different layer sizes not working (#64)
• Resolved confusion about device sizes needing to be specific (#3, #65)
• Fixed failing test cases (#67)

Performance Improvements

• Reduced slicing time

Known Issues:

• Large number of TPMS structures cause rendering and slicing to crash (memory overflow)
• Massive numbers of components (many thousands) also cause crashing (memory overflow)
