Which production technique typically results in less material waste?
This technique involves injecting molten material into molds, leading to minimal excess material.
This technique involves cutting away material, which often results in more scrap.
While efficient, this technique can still produce waste depending on the design and support structures.
This is a set of principles rather than a specific production technique.
Injection molding generally results in less material waste compared to CNC machining because it uses molds to shape materials, reducing scrap. CNC machining involves cutting away from larger blocks of material, leading to more waste. 3D printing efficiency varies with design complexity, and lean manufacturing is a process optimization strategy.
Which production method is more labor-efficient due to automation?
This method allows continuous operation with minimal manual intervention.
This method requires moderate labor for mold adjustments and setup.
This method often involves significant manual programming and oversight.

3D printing is more labor-efficient due to its high level of automation, allowing for continuous operation with minimal supervision. In contrast, injection molding requires moderate manual intervention for mold changes, and CNC machining involves detailed programming. Lean manufacturing enhances efficiency across processes rather than acting as a singular technique.
Which design methodology focuses primarily on accessibility for all users without the need for adaptation?
This method is known for creating products that are usable by the widest range of people possible.
This approach emphasizes diversity and social equity, adapting to various user needs.
This method prioritizes user needs by involving them in the design process.
This is not specifically a design methodology but a project management approach often used in software development.
Universal Design aims to ensure accessibility for all users by integrating flexibility and intuitive interfaces. It handles a broad range of user needs without requiring adaptation, unlike Inclusive Design which focuses on diversity, or Human-Centered Design which addresses specific user challenges.
What is the primary focus of Inclusive Design in managing complexities?
This approach allows for adaptation and multiple means of engagement, considering cultural sensitivity.
This is more aligned with a method aiming for accessibility across the board.
This focuses on engaging users throughout the design process to address specific challenges.
