What is one common post-processing step required for parts printed using the SLS process?

• Curing under UV light

• Sintering in a furnace

• Removal of excess powder

• Application of a liquid binder

In Selective Laser Sintering (SLS), what energy source is used to fuse powdered material?

• Ultraviolet (UV) light

In Powder Fusion 3D printing processes, what is the role of the energy source?

• It selectively melts or sinters the material needed for each layer.

• It heats the bed of powder to a consistent temperature.

• It moves the print head over the powder surface.

• It spreads a thin layer of powder across a build surface.

What is NOT the preprocessing step?

• Create CAD model

• Create G code

• Part orientation on the build platform

• Print the part

What is the purpose of slicing in the 3D printing process?

• To create support structures

• To generate G-code instructions for the 3D printer

• To check the quality of the STL file

• To divide the 3D model into vertical layers

Which of the following is a common post-processing step for Fused Filament Fabrication (FFF) 3D printed parts?

• Heat treatment to strengthen the part

• Wire EDM to detach the part from the build platform

• Removing supports and cleaning

• Applying a special surface treatment for residual stress management

In the context of 3D printing, what does CAM stand for?
