New Bicontinuous Additive Manufacturing Process Using Functionally Graded-Materials

Recommended Posts

I am a student at Penn State working with a new additive manufacturing invention in one of our entrepreneurship classes. My team's goal is to find the best possible application for this process in the market. Our thought is to target the biomedical field to see if there are specific companies that could benefit from this invention. Below is some additional information about the invention, if there is any incite that anyone could share with us that would be greatly appreciated. 

Technology Description: This patent pending technology presents a solution for both thin film and bulk 3D printed FGMs by digitizing the design’s geometry into hundreds of thousands of aligning micron sized cubes. Each cube is represented by a gyroid structure, which typically has a volume and empty paths or tunnels that mathematically maze through the structure. However in this process, the maze is filled in with the other selected material creating a mechanical advantage from the intertwining material paths. Both the gyroid material and the maze material separately but continuously flow into the surrounding cubes, repeating the gyroid pattern from cube to cube. Since each material is continuous throughout the entire design, the component exists as two continuous discrete structures, not only bonded together, but mechanically blocking each other from separating. The final product will increase the multi-material bond strength compared to current FGM techniques. This process creates a superior connection between two materials allowing characteristics such as: anti corrosive, high flexibility, high/low thermal conductivity, temperature resistant, biodegradable, and more.



  • Component composition can durably integrate multiple desired material properties

  • Replace after production coatings or adhesives between materials

  • Tangled gyroid process delivers a mechanical advantage over current FGM processes

  • Micron sized gyroid structures have no effect on print time
