What it does:

You can generate minimal surface structures in any desired dimension and save them as .stl-file. An overview of the possible scaffolds/structures follows below.

How to run?

The software was tested with Python 3.7 under Ubuntu 19.04.

Or open the folder in Terminal and run it with: python app.py Needed packages are:

• numpy
• vtk
• pypubsub
• wx

Explanation of the sliders:

• Number of primitive cells in X,Y,Z direction - changes the number of unit cells in each direction

• Quality factor - changes the surface quality of the structure, lower values took longer to render

• Wall thickness - changes the thickness of the wall seen from the surface of the minimal surface structure

Overview of the different possible scaffolds

Currently the following triply periodic minimal surfaces are available:

• Schwarz P
• Schwarz D
• Gyroid
• F-RD
• Neovius
• iWP
• L-Type
• G'
• Tubular G
• Tubular P
• P_W_Hybride
• I2-Y
• Skeletal 1
• Skeletal 2
