3DP process Parameter part1

1. Which of the following CAD operations is typically used to create a 3D object from a 2D sketch?

• Extrusion

• Fillet

• Shell

• Chamfer

Build parameters like nozzle temperature and printing speed have no impact on print quality

• True

• false

What does infill density control in 3D printing

• The surface texture of the print

• The internal structure and strength of the print

• The material used for the print

• The resolution of the print

Which of these build parameters affects the surface finish of a 3D print?

• Layer height

• Infill density

• Nozzle diameter

• Print speed

How does layer height affect layer adhesion in 3D printing?

• Smaller layer heights improve adhesion between layers

• Larger layer heights improve adhesion between layers

• Layer height has no effect on adhesion

• Higher layer heights lead to better surface finish but weaker adhesion
