I have been fortunate enough to be involved in several prosthetic limb design projects over the past few years:
The Isabella Arm was created for a young girl who loves care bears and was born without a fully formed arm. Bethany, Dylan and I designed an elbow actuated prosthetic for her inspired by the enable open source prosthetic limb community. We cast a replica of her limb which we then scanned and used to design around in CAD. The open source design incorporates many dynamic features such as print in place hinges, adjustable wrist angle, adaptive grip, and ratcheting tension system. The design is available for download on instructables.com and enable’s website.
The following summer Bethany and I participated in a mentorship program for KidMob, a prosthetic limb workshop through Autodesk where we collaboratively designed a prosthetic with David, a 13 year old who uses a supportive splint. David is very active and wanted to create attachments to the splint that allowed him to do more with his limb when kayaking, horse riding, swimming and skiing. We scanned David’s splint and recreated it with 3D printing, adding the capability for modular attachments specific to each activity.

My deep interest in Additive technology has lead me time and again to the medical field - the promise of unrestricted form factors, integrated tech, and new materials has motivated me to explore the cast - a design that has not changed for decades.
#cast is a concept for a 3D Printed cast that explores the possibilities of an additively manufactured cast in a social media age.
I designed the #cast from a scan of my own arm, taking fictional “get well” posts from a social media page and wrapping them as text around the form of a cast. The cast was then 3D printed in SLS nylon, a viable end use material that is washable and can even be dyed to any color with fabric dye. Comfort was a key consideration in the design of the cast - the gaps between the letters provide breath-ability and a place to scratch! This design form and platform is only viable through additive manufacturing.

3D Printed #CAST for the Social Media Age
Social, 3D Printed Cast for Broken Bones
At FATHOM I was apart of a team that created a smart leg cast for Mike North of Prototype This! The cast integrates sensor technology and explores the possibility of augmented healing through a connected device.
The team scanned Mike’s leg and created a custom fitting cast with 3D printed ratchet straps, similar to snowboard bindings. Integrated sensor systems communicate data on the healing process while speaker systems create vibrations that are thought to improve healing time. The ratchet straps were integrated in order to account for the swelling that Mike’s foot would undergo during airplane travel - something that can be a complication with traditional casts. Mike wore this cast for the last few weeks of his healing process and traveled via plane to a conference on IoT medical devices.
I was intimately involved in all phases of the project. I performed the scanning and collaboratively created CAD of the main form with one other CAD designer.
FATHOM was commissioned to design the trophies for the East Bay Innovation Awards from 2014-2018. I was the lead designer on the 2015 and 2018 trophies. Each year we created 16 trophies utilize the latest additive techniques- embodying the spirit of innovation celebrated at these awards.
The design for 2018 was based on the Gyroid form. The complex surface design was achieved in grasshopper using Crystallon - a software that aids in the creation of computational lattice structures- and 3D printed in SLS nylon. Each trophy was unique.
2015: Topographic Map
The design for 2015 utilized NASA scan data to create a topographic map of the east bay. The map was embedded into the face of the trophy and LED lighting system was integrated into the base. The trophies were created using a full color polyjet 3D printer.

3DP Custom Infill
I created a custom infill pattern for FDM 3D Printers and utilized it in a large scale version of FATHOM’s logo and in business card holders distributed to FATHOM employees.
