Rapid Prototyping Flashcards
(13 cards)
Why is additive manufacturing suitable for early design prototypes?
It allows the creation of visual functional and presentation models without concern for material properties.
Which additive processes are commonly used for prototypes?
Stereolithography (STL) 3D printing (3DP) and fused deposition modeling (FDM).
What tolerances and surface quality do STL 3DP and FDM achieve?
Layer thicknesses of 0.05 to 0.3 mm manufacturing tolerances around 0.02 mm and surface roughness of at least 20 µm.
What economic benefit does rapid prototyping offer?
It avoids the need for forming dies saving time and costs especially for individual and small batch production.
Why is development time important in automobile and aircraft manufacturing?
Shorter development times lead to faster product delivery and improved quality.
How does rapid prototyping compare to physical and digital mock-ups?
Rapid prototyping reduces development time and improves quality more effectively than physical and digital mock-ups.
What is the benefit of simultaneous or concurrent engineering?
It performs several design activities in parallel and enables faster prototype production.
How does rapid prototyping support the design phase?
It speeds up development by quickly providing design and functional models.
Why do designers in the automotive and aircraft industries use rapid prototyping?
It allows fast creation of visual and functional models directly from CAD data with minimal preparation.
What is the main area of application for rapid prototyping?
Creating models and prototypes during early development especially for complex designs where time cost design and function must be balanced.
What are the key types of models made using rapid prototyping?
Design model for high geometric detail and surface quality
Ergonomic model to show operating functions
Functional model for testing functionality
Which industries use rapid prototyping and for what purposes?
Consumer products for appearance function and handling checks
Automotive for design freedom and component integration
Aerospace for optimized high-load components
Aircraft for planning structure and interiors
Healthcare for prostheses and implants
Machinery for complex product development
Architecture for appearance geometry and error detection in early design
How does rapid prototyping benefit architecture?
It allows early review of building details helping to avoid costly redesigns by shifting coordination and approval earlier in the project.
