easy📝 Conceptual Q11 of 15
Step-by-Step Solution
Solution:
Step 1: Understand OBJ format capabilities
OBJ files mainly store the shape or geometry of a 3D model without extra details like color or materials.Step 2: Understand 3MF format capabilities
3MF files include geometry plus additional information such as colors, materials, and textures, making them richer for 3D printing.Final Answer:
OBJ stores only geometry, while 3MF stores geometry plus color and materials -> Option CQuick Check:
OBJ = geometry only, 3MF = geometry + color/materials [OK]
Quick Trick: Remember: OBJ is simple shape, 3MF adds color and materials [OK]
Common Mistakes:
MISTAKES- Thinking OBJ supports colors and materials
- Confusing OBJ as a 2D format
- Assuming 3MF is always compressed
