Intact.design provides many material options, organized into six main groups:

• Ferrous metals
  • Contain iron and are usually magnetic. Used for their high tensile strength and durability.
• Non-ferrous metals
  • Lighter and more malleable than ferrous metals. These materials do not exhibit typical properties of metals such as hardness and conductivity.
• Non-metals
  • Includes materials such as concrete, glass, and rubber.
• 3D printed plastics
  • Inexpensive materials used in the 3D printing process.
• Engineering plastics
  • Harder and more durable plastics than 3D printed ones
• Biological materials
  • Different types of bones are currently supported

For a list of all the materials with their properties, download this excel sheet. In the Excel sheet, there are several lines to understand

1. Material name
2. Category: Ferrous metal, non-ferrous metal, non-metal, 3D printed plastic, engineering plastic (Organized by category in Intact.design)
3. Failure criterion: a way to measure how and under what conditions a material will fail. Materials either fracture (brittle failure) or yield (ductile failure). There are several failure criterion methods for each type of failure.
4. Density: defined by mass/volume
5. Elastic modulus: derived from the linear (elastic) region of the stress-strain curve; a measure of a material’s resistance to being deformed when a force is applied to it.
6. Poisson’s ratio: negative ratio of lateral strain to longitudinal strain.
7. Yield Strength: stress at which a material begins to deform plastically
8. Tensile Strength: the maximum stress a material can withstand before breaking while being pulled apart
9. Compressive strength: the maximum stress a material can withstand before breaking when being compressed
