Team 09 - Alternative Manufacturing to Optimize
Avionics/Electronics Designs
Nathaniel Rossi, Jonathan Nguyen, Ronald Anderson, Marcus Alameda
● Team was tasked with optimizing
an avionics/electronics design
● Determine the weight, structural
performance, and cost of DMLS
parts vs traditional methods of
manufacturing
● The goal is to reduce weight and
maintain performance

Preliminary Design
● Different lattice structures
simulated in Solidworks for
structural analysis
● Hexagonal Honeycomb lattice
structure selected for strength
and rigidity
● Design revisions made to
accommodate electromagnetic
interference shielding capability
● Solidworks simulation results
compared to original Honeywell
cast part as a baseline

Final Prototype
● Direct Metal Laser Sintering
(DMLS) selected as alternative
method of manufacturing
● Solid DMLS and three different
honeycomb lattice aperture
sizes prototyped for analysis of
strength and rigidity
● Machined variant prototyped
as well
● Simulation validated design
methodology and
manufacturability

Test Results & Conclusions
● Additive manufacturing, allows for new complex part
geometries like lightweight honeycomb structures
● DMLS presents a value created opportunity for rapid
prototyping
● DMLS components are greatly affected in weight reduction
but not in cost
● DMLS is beneficial for aerospace applications
