Objective: Through 10+ separate and different steps, turn a press-light on. Rotational & linear motion must be used, as well as rigid linkage systems. A projectile must shoot an object 13cm high, triggering the next step. Machine must start with a marble step, and must include a 3-second step. Projectile can only hit a target that is twice its size. Final product must demonstrate creativity and deliberate understanding of machining and types of motion.

Parts were designed with 3D FDA printing in mind, with most parts being 3D printed for testing and final designs.

Changes allowed for more controlled motion of marble, less variability, more delay time, and fixed output

Overview: In the Introduction to Design for Manufacturing (DFM) course, we delved into methodologies and tools that transformed the way I approach design. From mastering material selection, including both new and traditional options, to understanding the intricacies of primary manufacturing processes like cutting fundamentals, casting, forming, and shaping—I gained a comprehensive foundation. Designing with plastics, exploring elements like snap-fits and integral hinges, added a practical dimension to my skill set. Embracing concepts like Design for Assembly (DFA) and delving into the nuances of geometric dimensioning and tolerancing (GD&T) equipped me with a holistic understanding of crafting designs that are not just visionary but also optimized for real-world manufacturing. This course has enhanced my capabilities and shaped my approach to designing for efficiency and manufacturability.
