ITPEC FE Subject A October 2025 Question 10
ITPEC FE Subject A October 2025 — Question 10 of 60
3D Printer — creates physical objects layer by layer.
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 rule: 3D printer = creates physical objects from digital models; 3D scanner = captures physical objects into digital data.
