Picking the “best” process depends on what you’re optimizing for.
If you need big parts fast
FDM usually wins on volume and cost. Great for fixtures, housings, and prototypes.
If you need detail and smooth surfaces
SLA wins for small features, crisp edges, and paint-ready surfaces.
If you need tight tolerance or metal/plastics with known properties
CNC is the right tool when the drawing matters and material performance is non-negotiable.
Practical rule of thumb
- Start with requirements, not processes.
- Identify the one dimension/feature that must be perfect.
- Choose the process that controls that feature most reliably.
If you’re unsure, send the CAD and we’ll recommend the most cost-effective path.
