MEGR 2156 — Design Projects I Laboratory

Welcome to Juan's portfolio.

Hello, world. My name is Juan and this is my engineering portfolio.

In this site you will find a record of my projects, for MEGR2156, which will give you a clear idea of what I know and how I think. I will give thorough explanations of my decisions and the process that led me to completing each project. With each of these assignments I will demonstrate a clear understanding of the most important design principles, while remaining true to my engineering practices and ideas.

Orientation of this Course

Weeks 1–8: Fused Deposition Modeling (FDM)

Week 9: Laser Cutting

Weeks 10–11: Stereolithography (SLA)

Weeks 12–15: Final Project

Machines I will use

FDM — Prusa Core One

Laser Cutter

SLA — Formlabs Form 4

SLS — Formlabs Fuse 1+ (selected projects)

How This Portfolio Works

Every lab entry will answer three questions about my design process:

What did the process require?
Every additive manufacturing technology has design rules: constraints imposed by the machine, the material, and the process itself.

What did I design and why?
What choices did I make? What geometry, orientation, tolerance, or material decision was specific to the process I was designing for?

What did I learn?
What worked? What failed? What would I change if I printed it again?
