IMSE 250 Exam 3 Slide ReviewAdditive manufacturing names - ANS-3D printing
Rapid prototyping
Rapid manufacturing
Additive Fabrication
Direct Digital Manufacturing
Subtractive - ANS-Material is removed from a solid block until the desired shape is reached
(2.5M BC- Hominids)
Fabricative - ANS-Elements or material are combined and joined (6,000 BC- Western Asia)
Formative - ANS-Mechanical forces and/or heat are applied to material to form it into the desired
shape (3,000 BC- Egyptians)
Additive - ANS-Manufacturing processes where material is deposited in a layer-by-layer fashion
to fabricate a 3D part directly from CAD model (1984- Chuck Hull, 3D System Inc. USA)
AM (American Society for Testing and Materials)? - ANS-A class of manufacturing processes
where material is deposited in a layer-by-layer fashion to fabricate a 3D part directly from CAD
model
Typical additive manufacturing process - ANS-1. Design
2. Production
3. Post processing
FDM (fused deposition modeling) materials - ANS-Thermoplastic polymers
FDM markets - ANS-Prototyping, end-use products
SLS (selective laser sintering) materials - ANS-Polymers
Metals
SLS markets - ANS-Prototyping, direct parts
DLP (digital light projection) materials - ANS-Photopolymers
DLP markets - ANS-Prototyping
Jetting materials - ANS-Polymers
Metals
, Foundry sand
Jetting markets - ANS-Prototyping
Casting molds
End-use products
AM can - ANS-Make individual customized products
Produce products with complex structure (WYSIWYB)
AM will - ANS-Give industry new design flexibility
Reduce energy use
Shorten time to market
Additive manufacturing solution classification - ANS-On-demand services
3D printers
3D production systems
Additive manufacturing products - ANS-(Design)
Concept models
Functional prototypes
(Manufacturing)
Manufacturing tools
End-use parts
Typical design cycle - ANS-1. Concept design
2. Engineering
3. Detail design
4. Tooling
5. Production
(Design change in all steps)
Early - ANS-Prototype __________ to minimize the cost of change
66% - ANS-If a product is late to market by 6 months, already _____ of its gross profit margins
are lost.
Ideal design cycle - ANS-Design change occurs in the concept design, engineering, and detail
design stages.
Direct benefits- how product design is changing - ANS-Reduce time to market
-Solidify design earlier
-Reduce late design changes
Lower product development cost
-Design changes earlier in process
