ITPEC FE Morning April 2023 Question 14
ITPEC FE Morning April 2023 — Question 14 of 80
3D Printer — creates physical objects layer by layer using additive manufacturing.
A 3D printer builds three-dimensional objects using methods such as fused filament fabrication (FFF/FDM), where material is deposited layer by layer.
Why not others:
- (a) — describes a 3D scanner, which captures shape data from physical objects
- (b) — describes a thermal printer, which uses heated pins on heat-sensitive paper
- (d) — describes projection mapping, which projects graphics onto real-world surfaces
Key point: 3D printing = additive manufacturing — building objects by adding material layer by layer, not subtracting it.
