Design Modelling

Question 1

2D CAD

Answer 1

flat drawings of products and structures

Question 2

2.5 CAD

Answer 2

prismatic models

Question 3

3D CAD

Answer 3

realistic model of design object

Question 4

3D wireframe and surface modelling

Answer 4

a skeleton-like inner structure of the object being modelled

Question 5

Solid Modelling

Answer 5

the program calculates the dimensions of the object it is creating

Question 6

Data modelling

Question 7

virtual prototyping

Answer 7

software driven process that simulates products and environment by mimicking real world behaviours

to see errors, like crashing a car

Question 8

bottom up modelling
top down modelling

Answer 8

the chain

Question 9

rapid modelling

Question 10

laminated object manufacturing (LOM)

Answer 10

a rapid prototyping system that layers the adhesive coated paper, plastic or metal laminates glued together and cut to shape w knife or laser

Question 11

Stereo Lithography

Answer 11

selective polymerization of a photosensitive resin using ultraviolet light. ultraviolet laser beam focuses on the top layer of photo sensitive resin. the cured layers of polymer is lowered by a platform attached to it so a fresh layer cover the cured one.

Question 12

Selective Layer Sintering (SLS)

Answer 12

a high power laser beam selectively melts and fuses powdered material spread on a layer

Question 13

fused deposition modeling (FDM)e

Answer 13

relies on melting and selectively depositing a thin filament of thermoplastic polymer in a cross hatching fashion to form each layer
