Modelling & Prototypes

Question 1

What is a Block model?

Answer 1

Block models are a 3D representation of what the product will look like. They have no working or moving parts and can be manufactured from a variety of materials.

Question 2

Block modelling advantages

Answer 2

They construct an accurate representation of a final product which can help manufacturers determine the shape, size and details to the design.

Question 3

Block modelling disadvantages

Answer 3

Very high setup cost

Question 4

2D modelling advantages

Answer 4

Highly accurate drawings
Easy to edit drawings
Easy to store drawings

Question 5

2D modelling disadvantages

Answer 5

High cost of set-up
Files can be lost in system if not backed up
High-quality training required

Question 6

3D modelling advantages

Answer 6

Can clearly see around an object 360

Question 7

3D modelling disadvantages

Answer 7

High set-up costs

Question 8

What is rapid prototyping?

Answer 8

RPT machines have the capability to produce solid models from a variety of materials by taking thin horizontal cross sections from a 3D computer model to construct the physical model layer by layer.

Question 9

Rapid prototyping advantages

Answer 9

It shortens the design and development cycles and enhances design quality and accuracy and reducing development costs.
Complex and intricate models can be produced without the need for complicated machine-tool set up.
It allows designers to review the function, the manufacturer process and the marketability of a product all within days of the initial design.
