Inside This Unit: The Full Breakdown
Unit 2 surveys 3-D media and processes — additive (modeling, assemblage), subtractive (carving), casting, construction, and digital fabrication/3-D printing — plus armatures, structural integrity, and craftsmanship.
Why it matters
Portfolios must show experimentation with materials and processes, and 3-D work additionally demands that pieces physically hold together.
Key concepts
- Additive builds up material; subtractive removes it; casting reproduces from a mold.
- An armature is an internal support; structural integrity keeps work standing.
- Materials and processes should serve the idea.
Materials, Processes & 3-D Media
Explore additive, subtractive, casting, and construction processes, use armatures for support, and justify material choices by meaning. Breadth of process exploration strengthens the Sustained Investigation.
AP exam tip
Plan for structural integrity early — an armature or sound joinery prevents collapse and protects your portfolio.
