Total questions: 10
Worksheet time: 5mins
What is the primary advantage of using rapid prototyping in product development?
It eliminates the need for computer-aided design (CAD).
It allows quick and cost-effective testing of physical prototypes.
It replaces all forms of traditional manufacturing.
It guarantees that a final product will always be successful.
Which of the following manufacturing techniques is considered additive?
CNC milling
Laser cutting
Injection molding
Fused deposition modeling (FDM)
A company is designing a complex mechanical part with intricate internal cavities. Which rapid prototyping technique is most suitable?
CNC machining
Fused deposition modeling (FDM)
Laminated object manufacturing (LOM)
Selective laser sintering (SLS)
What is the function of the Standard Tessellation Language (STL) file in rapid prototyping?
It provides a physical mold for creating prototypes.
It acts as a design blueprint for subtractive manufacturing.
It converts CAD models into a format readable by 3D printers.
It is a proprietary software used for CNC machining.
Which of the following best describes the process of Stereolithography (SLA)?
It layers paper or plastic sheets and bonds them together with adhesive.
It uses a laser to selectively harden a liquid resin layer by layer.
It extrudes heated plastic filament to build up a 3D model.
It fuses powdered material using a high-energy laser.
A design team needs to create a low-cost prototype for a simple, one-time functional test. Which rapid prototyping method would be most appropriate?
Selective laser sintering (SLS)
Fused deposition modeling (FDM)
Injection molding
Stereolithography (SLA)
What is a key environmental benefit of additive manufacturing compared to subtractive manufacturing?
It always produces 100% biodegradable products.
It requires less energy to operate machines.
It generates significantly less material waste.
It eliminates the need for post-processing.
In Laminated Object Manufacturing (LOM), how are layers of material bonded together?
By using a heated extrusion nozzle
By a laser selectively fusing powder particles
By cutting and gluing stacked layers of material
By injecting liquid resin into a mold
What is a major limitation of fused deposition modeling (FDM) compared to stereolithography (SLA)?
FDM cannot print in multiple colors.
FDM has lower surface resolution and rougher finishes.
FDM materials are always weaker than SLA materials.
FDM is significantly slower than SLA.
A design team wants to manufacture a large batch of identical plastic parts with high precision. What method would be the best alternative to rapid prototyping for mass production?
CNC milling
Injection molding
Laminated object manufacturing (LOM)
Selective laser sintering (SLS)
