chapter 9

The extruded in a basic 3D printer does the following

• Feeds and melts the filaments

• Controls the xyz motions

• Control the motor drive

• Controls the print bed

The advantages of 3D printing are

• It’s cost efficient as compared to traditional manufacturing techniques(cheap - process easy than traditional)

• Creates less waste

• Takes more time to do something

• Less innovate due to extra costs

One of the 3D printing disadvantages

• Complex shapes can be produced

• Reduce design complexity

• Process is slow

• None

3D printing is called additive manufacturing because material is added to create the 3D object

• True

• False

What are valid types of 3D printers

• Laser Jet

• Led printer

• Stereolithography

• Fused deposition modeling

All the areas/industries where people use 3D printing

• Architecture and construction

• Medical

• Art and design

• Defence and space

One of the 3D printing challenges is

• Rapid prototyping

• Clean processes

• The cost of products materials and equipment are high

• None

1)-Create 3D CAD model

2)Create STL file

3)Create layer slicing software

4) send to 3D printers to print

Are the correct steps of 3D printing

• True

• False

Additive manufacturing complicates intellectual property

• True

• False

Addictive manufacturing or 3D printing are two different names for the

same concept.

• True

• False
