Exercise_03 AM THGA

What is the best polymer-based AM process?

• SL

• FDM

• SLS

• Depending on application

What is your understanding of the VPP-process "type b"?

• Point by point approach

• Vector scan

• Mask projection

• Higher power than type a

What is the reason for "overcure"?

• Faster process time

• Increasing bonding strength

• No need for support structure

• It is a type of heat treatment

What is the main difference between MJM and PJM?

• Thermal vs photochemical process

• Polymer vs metal

• One color vs multi-color

• Home vs industrial use

What is the reason for different colors in one part printed with material jetting?

• Multiple use of more than 1 printer

• Multiple material supply

• Locally heat by laser

• Locally heat by UV-lamp

How many basic principles of FDM exist according to Gibson?

• 3

• 5

• 7

• 9

Please indicate the advantages of solid filling by FDM.

• Stability

• Costs

• Strength

• Distortion

Why do we need intert gas for the SLS-process?

• Faster printing

• Cheaper processing

• Avoiding oxidation

• There is no need

What is the reason for using the "outline-laser" within the SLS-process?

• Higher hardness

• For printing of the support structure

• Reduction in energy consumption

• Smoothing of the outer surface
