Q

How does CNC milling work?

-Oscar Lawson

A

The opposite of 3D printing, it is a wasting, subtractive process. The finished product is machined and cut from a solid block into the desired shape

Q

What is rapid prototyping?

-Oscar Lawson

A

Quickly making a scale model of a part or assembly process. It often uses 3D CAD data and can check for accuracy, fit and aesthetics

16
Q

Is CAD quicker or slower than drawing by hand.

Yan K

A

It depends on the detail required.
A quick communicative sketch is often quicker by hand, but
A detailed engineering / manufacturing drawing is often quicker using CAD.

17
Q

What type of manufacturing process is 3D printing

-Krystian shanahan

A

Additive

18
Q

What type of manufacturing process is 3D milling

-Krystian Shanahan

A

Subtractive

19
Q

What might rapid beprototyping be used to test for?

-Krystian shanahan

A

Accuracy and quality of fit between components, or aesthetic qualities

20
Q

How are materials held securely during CIM processes

-Krystian Shanahan

A

Using automatic chucks and compressed air

21
Q

What is a disadvantage of CNC milling vs. 3D printing when trying to conserve materials?
Ivan k2

A

CNC milling is a wasting / subtractive process. 3D printing is additive.

22
Q

What is the most obvious examples of an additive process?

Ivan k2

A

3D PRINTING
