1. Which statement best describes the primary purpose of the Certified
Additive Manufacturing Technician (CAM-T) certification in Maryland?
A. To certify legal compliance in construction inspection practices
B. To validate foundational knowledge and applied skills in additive
manufacturing processes
C. To license individuals for independent industrial machine design
consultancy
D. To authorize unrestricted operation of all CNC machining systems in
manufacturing facilities
The CAM-T certification primarily evaluates a candidate’s understanding of
additive manufacturing principles, including processes, materials, safety,
and post-processing, rather than serving as a legal license or broad
machining authorization.
, 2. Which of the following best defines additive manufacturing in an
industrial context?
A. Subtractive removal of material using cutting tools
B. Joining metal sheets using thermal welding techniques
C. Layer-by-layer fabrication of objects directly from digital models
D. Manual assembly of prefabricated mechanical components
Additive manufacturing refers to the layer-by-layer construction of parts
from digital designs, distinguishing it from subtractive or assembly-based
manufacturing methods.
3. Which of the following is most commonly considered one of the seven
major additive manufacturing technologies?
A. Injection molding
B. Fused deposition modeling (FDM)
C. Sand casting
D. CNC milling
Fused deposition modeling is one of the standard additive manufacturing
processes, while injection molding, casting, and CNC milling are traditional
manufacturing methods.
4. What is the primary role of post-processing in additive manufacturing
workflows?
A. To design the original CAD model
B. To remove support structures and improve surface finish or mechanical
properties
C. To convert analog drawings into digital files
D. To calibrate industrial robots used in welding
, Post-processing improves part quality by removing supports, refining
surface finish, and sometimes enhancing mechanical properties after
printing.
5. Which material type is most commonly used in basic FDM 3D printing
applications?
A. Thermoplastic filament such as PLA or ABS
B. Liquid concrete mixtures
C. Titanium alloy powder exclusively
D. Raw crude oil derivatives
FDM printers typically use thermoplastic filaments like PLA and ABS, which
are melted and extruded layer by layer.
6. What is a key safety concern in additive manufacturing environments?
A. Exposure to ionizing radiation from lasers in all systems
B. Heat exposure, fumes, and mechanical hazards from equipment operation
C. High voltage shock from manual wiring of CAD files
D. Magnetic field distortion affecting printed geometry
Additive manufacturing environments can involve heated components,
emissions from melted materials, and moving machinery, all of which
present safety risks.
7. Which file type is most commonly used as the standard input for 3D
printing workflows?
A. STL (Stereolithography)
B. MP3 (Audio file format)
C. DOCX (Word document)
D. JPEG (Image file format)
STL files are widely used because they describe 3D surface geometry in a
format compatible with slicing software.
