Question

In relation to additive manufacturing, match the following:

 

• A. P-3-III, Q-1-IV, R-4-I, S-2-II
• B. P-3-II, Q-2-IV, R-4-I, S-1-III
• C. P-4-III, Q-2-IV, R-1-II, S-3-I
• D. P-3-II, Q-2-IV, R-1-I, S-4-III

Hint:

Additive manufacturing processes vary significantly in terms of material, technique, and application. Understanding the process and material compatibility is key to selecting the appropriate method for a given part.

Answer 1

The Correct Option is B

Step 1: Stereolithography (P)
Stereolithography (SLA) uses the liquid layer curing technique, where a liquid resin is cured by a laser layer by layer to build the final part.
The material commonly used in SLA is Epoxy.
Thus, P corresponds to 3-II.
Step 2: Fused Deposition Modeling (Q)
Fused Deposition Modeling (FDM) works by extruding melted polymer layer by layer, where the polymer solidifies as it cools down.
The most commonly used material in FDM is Acrylonitrile butadiene styrene (ABS).
Thus, Q corresponds to 2-IV.
Step 3: Laminated Object Manufacturing (R)
Laminated Object Manufacturing (LOM) uses sheet material deposition, where layers of paper or plastic are bonded and cut into shape to form the object.
The material used in LOM is Paper.
Thus, R corresponds to 4-I.
Step 4: Laser-Engineered Net Shaping (S)
Laser-Engineered Net Shaping (LENS) uses injection of powder stream and melts the powder using a laser to build up the material layer by layer.
The material used is commonly Titanium.
Thus, S corresponds to 1-III.
Step 5: Final Answer
The correct matching is:
P-3-II
Q-2-IV
R-4-I
S-1-III
Thus, the correct answer is option (B).
