FE Meshing and Analyses
3-D Printed Finite Element (FE) meshes.
The first ever.
I have personally developed a system for converting FE meshes directly into solid structures which I have dubbed "Meshagons". There is a lot to the story of Meshagons and their developement. I have described this in detail on my personal webpage ( and you can find it HERE.
Meshagons could be very useful for creating strong but very light 3-D printed parts. Also, they are quite beautiful and lend themselves to artistic/architectural objects and Jewelry.

Finite Element (FE) Analysis is the industry  standard for engineering, bioengineering, and architectural design.
A fundamental aspect of FE analysis is the ability to create meshes of complex structures.
There are many commercially available software tools for mesh generation... too many to mention; for example: ANSYS, ABAQUS, TetGen, TrueGrid, etc. Most of these software tools are focused on generating meshes from regular (CAD) shapes and designs.
However, the commercial mesh softwares often fail when attempting to mesh complex multi-domain organic structures such as the cell-seeded scaffold and Abdominal Aortic Aneurysm shown at the right. At TensorTek we have developed a number of novel software tools and algorithms for robust tetrahedral meshing tasks programmed in Matlab ( and C#; providing 'sliver-free' and multi-domain tetrahedral mesh generation directly from volumetric images. We use implicit surfaces to define the multi-domain boundaries, thus freeing from topological constraints. In addition, we have developed our own in-house non-linear FEA software.
Because every design problem is unique, we do not at this time provide a 'generic' software solution. Each project/analysis likely requires novel innovations in shape computation and we tailor sofware packages to the client's needs, developing or adapting our software to meet new challenges.
Please email: forconsulting whether for basic or for difficult meshing FE problems.
Recent Work
Multi-domain meshing of cells and scaffold material. Our meshing code works directly from volumetric images, whether from microscopy, or from MRI/CT sources.

A 3-D printed organic cubiod "Meshagon".
The first ever.
I can now generate meshagons with controlled density and thickness, which has broad implications for generating light but strong 3-D printed parts for engineering and architecture. Meshagons can be generated for pretty much any shape, because it is based upon my implicit surface mesh generator. From a creative standpoint, meshagons are just really fun to hold and view.
I am in the process of developing a store for purchase of meshagons. 
If you have questions or are interested in a custom meshagon (examples: a company logo, initials, custom jewelry concept, or custom engineering or architectural component such as a light fixture or installation) please feel free to email me.
