1. What is the primary purpose of additive manufacturing?
A. Cutting materials away from a block
B. Joining metal sheets only
C. Building objects layer by layer
D. Painting industrial parts
Answer: C
Rationale: Additive manufacturing creates objects by adding material
layer by layer rather than removing it.
2. Which of the following is commonly used in 3D printing filaments?
A. PLA
B. Concrete
,C. Diesel
D. Copper wire
Answer: A
Rationale: PLA (Polylactic Acid) is a widely used thermoplastic filament
in 3D printing.
3. What does STL file format represent?
A. Surface Tessellation Language
B. Standard Triangle Language
C. Stereo Lithography
D. System Tool Logic
Answer: C
Rationale: STL stands for StereoLithography, commonly used for 3D
printing models.
4. What is the role of slicing software?
A. Designs models
B. Converts 3D models into printer instructions
C. Melts plastic
D. Paints finished parts
,Answer: B
Rationale: Slicing software converts 3D models into layers and
generates G-code.
5. What is G-code used for?
A. Programming 3D printers
B. Designing CAD models
C. Measuring materials
D. Cleaning machines
Answer: A
Rationale: G-code contains instructions that control 3D printer
movements and operations.
6. Which process is most associated with FDM printing?
A. Powder sintering
B. Layer-by-layer extrusion of thermoplastic
C. Laser melting metal powder
D. Photopolymer curing
, Answer: B
Rationale: FDM (Fused Deposition Modeling) uses extruded
thermoplastic filament.
7. What is the main function of a 3D printer nozzle?
A. Cooling material
B. Extruding melted filament
C. Storing filament
D. Scanning objects
Answer: B
Rationale: The nozzle melts and deposits material onto the build
platform.
8. What is bed leveling in 3D printing?
A. Cleaning the print bed
B. Adjusting the build surface for accuracy
C. Painting the platform
D. Heating the printer
