1. What is the primary purpose of a slicing software in additive
manufacturing?
A. To design 3D models
B. To convert CAD models into machine instructions
C. To test material strength
D. To polish printed parts
Answer: B
Rationale: Slicing software converts 3D CAD models into layer-by-layer
instructions (G-code) for the printer.
2. Which process uses a laser to fuse powder material layer by layer?
A. FDM
B. SLA
,C. SLS
D. CNC milling
Answer: C
Rationale: Selective Laser Sintering (SLS) uses a laser to fuse powdered
materials.
3. What does FDM stand for?
A. Fine Deposition Modeling
B. Fusion Deposition Manufacturing
C. Fused Deposition Modeling
D. Fabrication Digital Method
Answer: C
Rationale: FDM stands for Fused Deposition Modeling, a common
extrusion-based 3D printing method.
4. Which material is most commonly used in FDM printing?
A. PLA
B. Titanium
C. Ceramic powder
D. Resin
,Answer: A
Rationale: PLA is widely used due to its ease of printing and low cost.
5. What is a common defect caused by insufficient bed adhesion?
A. Over-extrusion
B. Warping
C. Stringing
D. Layer shifting
Answer: B
Rationale: Poor bed adhesion often leads to warping of the printed part.
6. What is the function of support structures in 3D printing?
A. Improve color quality
B. Reduce material cost
C. Support overhanging features
D. Increase printing speed
Answer: C
Rationale: Supports are used to hold up overhanging or complex
geometries.
, 7. Which layer height typically results in higher print resolution?
A. 0.3 mm
B. 0.2 mm
C. 0.1 mm
D. 0.5 mm
Answer: C
Rationale: Smaller layer heights improve surface detail and resolution.
8. What does SLA printing primarily use to cure resin?
A. Heat
B. UV light
C. Pressure
D. Air drying
Answer: B
Rationale: SLA uses ultraviolet light to cure liquid resin.
9. Which file format is most commonly used for 3D printing models?
