Every fabrication project starts with a prototype. This is a collection of 3D printing work focused on functional engineering parts: structural brackets, tolerance-fit mechanical assemblies, and material selection studies for load-bearing applications.

Timeline
2023 — Present
Most 3D printing guides are written for decorative parts. The focus here is always functional — parts that need to survive vibration, impact, and load. That means getting serious about material selection, slicer settings, orientation, and infill strategy.
PETG outperforms PLA in nearly every structural application — better impact resistance, higher heat deflection, and less brittleness under cyclic stress. Print orientation matters more than infill percentage for tensile strength. Layer adhesion is the failure mode, not material bulk.
Developing wrist module prototypes for the BCC robotic arm — iterating on joint geometry, wall thickness, and press-fit tolerances. Each print cycle produces dimensional data that feeds back into the Onshape model.
