Lecture 7- AM for product development

Question 1

(EXAM)Describe the four Physical model categories that could be used in
AM for product development?

Answer 1

Geometric:
• Validate geometry and
assembly, materials not
so important

Design:
• Full size or scaled they
enhance communication
between partners. Good for
checking concept / aesthetics
etc., accuracy not important

Functional:
• Allows some testing that is
similar to the market
function of the part - similar
or same material properties
are desirable
Technical:
• Have all the functional
features, manufacturing
process may be slightly
different

Question 2

6 Reasons for physical model

Answer 2

Concept

Fit- to test the dimensions on the design

Form - to assess the aesthetics and ergonomics of the
part

Function

Bid Requests - to assess the product from the supply
standpoint

Marketing - communicating a design to a non-design
based consumer

Question 3

Features that make AM attractive

Answer 3

complex geometries are achievable

Cad to part in short time-good for product development

Low productions volumes makes AM VERY cost effective
