FDM vs Resin 3D Printing for Custom Parts
FDM is usually better for larger functional parts and cost-sensitive prototyping, while resin is better for finer detail, smoother surfaces, and smaller precision-oriented components.
When FDM Makes More Sense
- larger parts
- functional prototypes
- engineering trial pieces
- lower-cost part iteration
When Resin Makes More Sense
- small detailed parts
- presentation models
- surface-sensitive prototypes
- high-detail visual work
How to Decide
The best choice depends on geometry, functional requirements, tolerances, finish expectations, and budget.
