3D Printing

Question 1

What are the 5 main types of 3D printing?

Answer 1

• Selective Binding
• Selective Solidification
• Selective Deposition
• Laminated Object Manufacturing
• Laser Deposition Technology

Question 2

What is Selective Binding?

Answer 2

Made from a poweder by applying binding agents to fuse the powder’s particles together

Question 3

What are the two types of selective solidification?

Answer 3

1) Stereolithography (SLA)

2) Selective Laser Sintering (SLS)

Question 4

What is Stereolithography (SLA)?

Answer 4

• UV laser beams cure successive layers of a photosensitive liquid polymer

Question 5

What is Selective Laser Sintering (SLS)?

Answer 5

• In contrast to SLA, bulk powder material is used
• SLS is generally stronger and more durable than SLA, however SLS components have a powdery finish.
• SLS is easier to surface finish

Question 6

What is the main type of Selective Deposition method and what does it do?

Answer 6

• Fused Deposition Modelling (FDM)
• Filament-based Fused Deposition Modelling (FDM) is the most common low-cost printer, heating a filament of polymer and extruding around each layer. While SLS and SLA can produce near-homogeneous products with a good finish, FDM often has a coarser finish, depending on the layer height and filament diameter, and its strength depends on the layer orientation.

Question 7

What does FDM stand for

Answer 7

Fused Deposition Modelling

Question 8

What is Laminated Object Manufacturing?

Answer 8

• Takes thin materials like paper or plastic sheets, cuts them to a specific shape and then uses adhesive to glue one layer to the next.

Question 9

What is Laser Powder Forming (Laser Deposition Technology)?

Answer 9

• Laser Deposition Technology (LDT) is a process in which metal powder is injected into the focused beam of a high-power laser under tightly controlled atmospheric conditions.
• Uses a focused laser beam as the heat source for depositing powdered metals.
• A variety of metals and alloys can be used.
