HW 4 prototyping

This additive process doesn’t need any post-modeling curing and uses ultraviolet bulbs to instantly cure and harden each deposited layer

What is the purpose and an example of “proof of concept” prototype

Purpose: determine whether the proposed solution is technically viable before investing in detailed design and production (test and validate the feasibility of a concept or idea)

Example: designing light weight , energy efficient cooling system for electronic devices

What is the purpose and an example of functional prototypes

Purpose: test and refine products mechanical features, ensuring it meets the intended specifications (functionality and performance of the final product)

Example: building a prototype of a new type of robotic arm to assess its range of motion and precision

What is the purpose and an example of visual prototypes

Purpose: to give people a representation of final products looks (aesthetics of the product)

Example: creating a physical or digital model of a new consumer product, like a sleek and ergonomic computer mouse

What is the purpose and and example of the user experience prototypes

Purpose: to gather feedback from potential users early in the decision process and refine the user interface (how prototype interacts with user and its usability)

Example: developing a clickable prototype for a mobile app to test user navigation and functionality

What is the fidelity of a prototype? And what is low fidelity and high fidelity

How similar the prototype is compared to the actual product. Low is using cheaper things but still showing force, distribution, and failure mode. High is something that is very similar to the finished product

What is Stereolithography?

Entire layers of resin are laid down and then a laser is what causes it to have shape and harden

What is polyjet?

Multiple resins and colors can be used at once and it is laid down without a resin vat

What is FDM? (Fused deposition modeling)

Small strands of resin are laid down at one and then hardened with light

What is electron beam lithography and photolithography

When a resin is poured into a mold and hoarded by light. When a photo uses light to create images
