3I’S TECHNOLOGIES
Industrial Product Engineering
At 3I’s Technologies, I assisted in the design of a low duty powder feeder. 3I’s Technology special-
izes in powder feeders, but their previous feeder designs were larger and more complex. The goal was to
simplify designs and reduce the costs of production.
The render above is the resulting design. This feeder takes design cues from other products, tak-
ing advantage of similar drive systems, feed gears, and bearings as previous designs. The simple design
makes customization and maintenance easier. Parts are easily accessible and replaceable during product
use. The package is smaller and lighter, making multi-unit deployments easier. Besides functional chang-
es, this feeder is much cheaper to produce than previous designs. 3I’s Technologies previously used local
machine shops to manufacture parts for these systems. This system takes advantage of 3D printing to
produce parts with complex geometries. In the model above, the top hopper and the black bearing sup-
port blocks are designed to be 3D printed using 3D printing services. These parts were redesigned and
strengthened appropriately to provide similar strength to their metal replacements.
During this project, I created all 3D models and manufacturing drawings for the system. I helped
prototype the system, often evaluating the strength and versatility of 3D printed solutions. For some of
the early systems, I also produced metal parts for testing. This feeder is currently in use by serval compa-
nies and will become the main feeder produced by 3I’s Technologies.

At 3I’s Technologies, I assisted with the creation of
system deployments. Feeders designed and built by 3I’s
Technologies were assembled with hoppers, conveyors,
and scales.
The system shown here uses the two low duty feed-
ers to measure and dispense powdered colorants. Hoppers
for the feeders were filled with conveyors that transported
the material from the floor above. The feeders dispensed
powder into scales before being discharged. The frame on
the right is the support structure for the system.
During this project, I created all CAD models and
produced manufacturing drawings for every piece of this
system. I assisted in the prototyping and assembly of the
feeders before finalizing designs.

AUSTLEN BABY CO.
Consumer Product Engineering
Shown here is the Entourage stroller by Austlen Baby Co. During my time at the company, I pre-
pared the back handle for manufacturing. The plastic parts were designed to be injection moldable and
drawings were created for the manufacture of the metal pieces.
Besides design for manufacturing, I also worked on side projects to improve the design and func-
tionality of the stroller. I designed and prototyped a better folding mechanism for reduced size and
smoother actuation. The new design hid the folding mechanism within the front seat structure. In addi-
tion, I helped design the car seat adapter and the accessory attachment system for the back handle. Due
to these designs, I am listed as an inventor on two patent applications for Austlen Baby Co. The applica-
tions are linked below.

DREXEL BIOMEDICAL JOYSTICK PROJECT
Parametric CAD Design
In 2015 I was approached by a senior design team at Drexel University. The team of biomedi-
cal engineers were designing a wheelchair joystick for people with arthritis. The design of the joy-
stick was customized for each user and 3D printed for use. The team needed assistance with the 3D
modeling and customization of the design. I created a 3D model in Solidworks with variable geome-
try in mind. The resulting model took in hand measurements and altered dimensions accordingly.
The renders show di>erent versions of the same part due to di>erent input dimensions.
The customizations include size of palm rest (top dome), width of shelf (distance from center), and
length of shelf (distance around center). The top render has the largest palm rest, largest length of shelf,
but smallest width. The bottom renders share the same self length and width, but with di>erent palm rest
sizes. The dimensions and features used to design the part were chosen to ensure that a large range of
dimensions could be accommodated without geometric issues.

The goal of the project was to simulate the conduction of heat through the skeleton of
a lunar rover and investigate materials to mitigate the buildup of heat.
The simulation used thermodynamic equations and material properties to simulate
the heat throughout the rover. The body of the rover with layers of insulation material over
an aluminum frame were assembled with cubic centimeter blocks. Using equations for
conduction, radiation, and heat absorption, the transfer of heat between the various materials
and the surrounding environment were calculated over time. For analysis, areas could
monitored through graphs or generated Excel files.
Due to time constraints, it was impossible to test all material options as planned. It
was noted that the skeleton would not dissipate enough eat from the motors and electronics.
Radiation shielding also reduced the heat that could be radiated away.

At SPS Technologies, I built an operator performance tracker with 5 week history and
quality tracking. This project intelligently parsed a weekly Excel hours sheet to generate a
productivity summary for each operator. A quality section was added to allow the supervisor
track quality issues associated with an operator. The final version included a way to add and
delete operators without code manipulation.
The entire system ran in Microsoft Excel and was successfully used by the forging
department.

to show the progress of the team over

PERSONAL PROJECTS
Surface Modeling
My experience and interests have pushed me to pursue consumer and industrial product engi-
neering. I enjoy the problem solving, prototyping, and CAD design that goes into making a product. As
CAD design is one of the most important facets of my experience, I am always looking to improve my
skills and learn new methods. To push the boundary of CAD design, I am currently learning surface mod-
eling. I was introduced to surface modeling at Austlen Baby Co., and realized that it was a powerful tool
for complex geometry. The examples shown here are models that show o> surface modeling. These piec-
es are created from reference images and would be hard to create with solid modeling techniques. The
examples were created in Solidworks.

I am still working on the top (separate model) and preparing renders.
