- 100% 3D Printed with HP MJF (TPA)
- Personalized, lattice midsole with field-driven stiffness
- Integrated, woven lattice upper
- Functional prototypes printed
This was a functional prototype I developed with my colleague and mentor Jerry O'Leary. After we
came up with the base sneaker design, I designed several zones of elastomeric lattice structure
combined with
the solid components to form a cohesive, single-piece design (apart from laces).
The
upper is a
woven lattice structure using a custom latticing method I developed. The midsole is a tuned
lattice structure with zonal stiffnesses designed using Grasshopper, nTopology, and some custom
tools. The lattices are parametric and can be easily updated for different shoe sizes or
mechanical performance.
These prototypes were made using MJF technology and TPA material. Several of these prototypes
have
been printed and worn around in various sizes.
- Injection molded clamshell assembly
- Glass filled nylon substrate, TPU overmolding
- Functional prototypes (T1 samples) in field testing
*Actual product under NDA
This was a design for injection molding project. We took the initial concept design, a tool handle needing to withstand specific loading and environmental conditions, and performed a redesign for manufacturability. We came up with a design consisting of a clamshell structure (glass filled nylon substrate) for structure and housing internals along with soft, textured, TPU overmolding. We validated the prototype through finite element simulation and additively-manufactured prototypes prior to field testing.

- 3D Printed with HP MJF (TPA)
- Lattice structure tuned for rebound
- Functional prototypes printed
This project was a proof of concept prototype for a 3D printed, airless tennis ball. I designed a two-layer custom lattice structure that would withstand the required forces and provide the desired rebound. These were manufactured using HP MJF technology and TPA material. The design involved a combination of Rhino, Grasshopper, and nTopology.
- STL Viewer
- Command-based, inspired by rhino
- Focus on being minimal
This is a (work in progress) test to see what it would take to get a minimal, useful online STL viewer working. This is inspired by my favorite 3D Viewport experience (Rhino). The primary goals with this are to make it fast and familiar to use for engineers. Current functionality includes model uploads, visibility toggling, ground plane & axes, iso/perspective toggle, screenshots, wireframe, and more. WIP functionality includes better instructions/help, a measuring tool, rotation/translation, and whatever else seems like it would be useful to add. Also, bug fixes.
- Running in the Browser
- Automatically generated design
- Live updating and rendering of parametric design
This project was a test of a web application that would allow a user to tweak parametric designs operating on their own files. The use case shown is an example where a file is upload, a bone plate is automatically generated, and the user can tweak the parameters using sliders to see it update in real time. This project runs in the browser and is fully custom built using Three.js and Grasshopper.
- Some miscellaneous programming demos
- P5.js, THREE.js
