TERM 3 QUIZ WEEK 2

What are type format of 3D printing file being used in design for 3D printing?

• .PDF

• .STL

• .DOC

• .MP3

Which are NOT the 3D design software that can be used for design for 3D printing?

• Fusion360

• TinkerCAD

• Adobe Illustration

• SketchUp

Which is the desirable geometry characteristic for design for 3D printing?

• Does not have any overhangs that cannot be printed without support structures

• does not have any residue

• does not have cornered edges

• the size must be as big as possible

How to determine the maximum scale of the printed parts?

• Based of the printing speed of the 3D printer

• Based of the maximum voltage of the 3D printer

• Based of the maximum size of the nozzle from the 3D printer

• Based of the maximum allowable printing area of the 3D printer

Which one of the process consider as post-processing process?

• Initial measuring from the drawing

• Sanding & painting

• Bed levelling

• Nozzle cleaning

What is meant by snap fit?

• common way to cut two or more parts together

• common way to connect SD card and 3D printer

• common way to move two or more parts together

• common way to connect two or more parts together

Design for assembly emphasize on assembly tolerance. What is meant by assembly tolerance?

• Assembly tolerance mainly reflects the number of parts

• Assembly tolerance mainly reflects assembly parts size

• Assembly tolerance mainly reflects assembly position precision between parts

• Assembly tolerance mainly reflects the geometry of the parts

Which is NOT the material that can be used for 3D printing?

• Cloth

• PLA

• ABS

• TPU

Why supports is needed in design of assembly

• allowing you to add more intricate details and features to your design

• Increase 3D printing time

• Make fitting much more nicer

• Increase the strength of the printed parts

What is the importance of the layer orientation/size for design for assembly?

• Increase the tolerance of the printed parts

• Having smoother surface & ease assembly process

• Having rougher surface

• Increase the printing time of the printed parts
