CAMT CAMT Software & Digital Workflow 1 — Questions and Answers
Question 1: What file format is most commonly used to transfer 3D models to additive manufacturing slicing software?
- DWG
- STL (Correct answer)
- IGES
Correct answer: STL
STL is the industry-standard file format for transferring 3D models to additive manufacturing slicing software due to its wide compatibility.
Question 2: What is the primary function of slicing software in the additive manufacturing workflow?
- Design 3D models from scratch
- Convert a 3D model into layer-by-layer machine instructions (Correct answer)
- Inspect printed part dimensions
- Manage material inventory
Correct answer: Convert a 3D model into layer-by-layer machine instructions
Slicing software converts 3D CAD models into layer-by-layer toolpath instructions (G-code) that guide the additive manufacturing machine during the build.
Question 3: Which file format was developed by a major industry consortium specifically to address limitations of STL, including support for color and material data?
- OBJ
- AMF
- 3MF (Correct answer)
- STEP
Correct answer: 3MF
3MF (3D Manufacturing Format) was developed by the 3MF Consortium to overcome STL limitations by natively supporting color, multiple materials, and metadata.
Question 4: What does G-code represent in the context of FDM additive manufacturing?
- A color-coding system for materials
- Step-by-step movement and process instructions for the machine (Correct answer)
- A quality grading standard for printed parts
- A material classification system
Correct answer: Step-by-step movement and process instructions for the machine
G-code is the programming language containing step-by-step movement, temperature, and extrusion instructions that control FDM and other CNC-based additive manufacturing machines.
Question 5: In FDM slicing software, what does the 'infill density' parameter control?
- The surface layer resolution
- The percentage of solid material filling the part interior (Correct answer)
- The nozzle temperature profile
- The print head travel speed
Correct answer: The percentage of solid material filling the part interior
Infill density determines the percentage of the part's interior volume filled with material, directly affecting part weight, strength, and material consumption.
Question 6: What is the purpose of automatically generated support structures in slicing software?
- To permanently reinforce the finished part
- To provide temporary material beneath overhanging features during the build (Correct answer)
- To improve the overall surface finish of all faces
- To reduce total material consumption
Correct answer: To provide temporary material beneath overhanging features during the build
Support structures provide temporary scaffolding beneath overhanging features that cannot be self-supporting during printing, and are removed during post-processing.
