Worksheet time: 5mins
What is another name for 3D printing, and how does it construct objects?
Subtractive manufacturing; by removing material from a block.
Additive manufacturing; by building objects layer by layer.
Computer Numerical Control; by carving precise shapes.
Rapid prototyping; by molding liquid materials.
What is the primary function of CNC machining?
To create objects by adding layers of material.
To carve precise shapes from raw materials using automated tools.
To design complex geometries using digital software.
To rapidly prototype new product designs.
The core difference in how 3D printing and CNC machining create objects is that 3D printing is an additive process, while CNC machining is a:
Formative process.
Subtractive process.
Generative process.
Transformative process.
What is CNC machining particularly known for?
Building objects layer by layer.
Rapid prototyping of simple designs.
High precision and material versatility.
Low cost for small batch production.
What is a potential drawback of CNC machining, especially for large-scale production?
It cannot create precise shapes.
It is often time-consuming and costly.
It has limited material options.
It requires manual operation.
Which of the following is a key advantage of 3D printing?
High precision and accuracy for all materials.
Cost-effectiveness for large-scale production.
Creation of complex geometries and rapid prototyping.
Extensive material versatility.
In which application does 3D printing particularly excel?
Large-scale production of simple parts.
High-precision machining of metal alloys.
Rapid prototyping and creating complex structures.
Mass production with minimal material waste.
What are some limitations of 3D printing?
It is too slow for rapid prototyping.
It struggles with complex structures.
It has limitations in accuracy, material options, and production batch sizes.
It is primarily used for large-scale production.
Which of the following is NOT a factor to consider when choosing between 3D printing and CNC machining?
Production volume.
Geometric complexity.
Post-processing needs.
The color of the final product.
What is a potential benefit of combining CNC machining and 3D printing technologies?
It makes both processes mutually exclusive.
It eliminates the need for post-processing.
It can optimize manufacturing by leveraging the strengths of both.
It reduces the geometric complexity of designs.
