3D Printing - Fundamentals
Consider this simplified SLA printing code snippet:
layers = 3
for i in range(layers):
    print(f"Curing layer {i+1}")
    print("Platform moves down")
    print("Resin recoats")

What will be the output?
APlatform moves down Resin recoats Curing layer 1 Platform moves down Resin recoats Curing layer 2 Platform moves down Resin recoats Curing layer 3
BResin recoats Platform moves down Curing layer 1 Resin recoats Platform moves down Curing layer 2 Resin recoats Platform moves down Curing layer 3
CCuring layer 1 Curing layer 2 Curing layer 3 Platform moves down Resin recoats
DCuring layer 1 Platform moves down Resin recoats Curing layer 2 Platform moves down Resin recoats Curing layer 3 Platform moves down Resin recoats
Step-by-Step Solution
Solution:
  1. Step 1: Analyze the loop and print statements

    The loop runs 3 times (i=0 to 2). Each iteration prints three lines in order: curing, platform moves down, resin recoats.
  2. Step 2: Write output for each iteration

    Iteration 1: "Curing layer 1", "Platform moves down", "Resin recoats"; similarly for layers 2 and 3.
  3. Final Answer:

    Curing layer 1 Platform moves down Resin recoats Curing layer 2 Platform moves down Resin recoats Curing layer 3 Platform moves down Resin recoats -> Option D
  4. Quick Check:

    Loop prints 3 sets of 3 lines in order [OK]
Quick Trick: Follow loop iterations and print order carefully [OK]
Common Mistakes:
MISTAKES
  • Mixing order of printed lines
  • Forgetting loop runs 3 times
  • Assuming prints happen outside the loop
