CNC vs. Metal 3D Printing: How to Compare Costs Accurately
Engineers often face a simple question with complex implications:
Should this part be CNC machined or 3D printed in metal?
The answer depends on geometry, tolerances, material usage, and — most importantly, cost. Yet getting accurate cost comparisons is notoriously difficult when suppliers quote in different ways, using separate pricing models and lead time assumptions.
That’s where digital manufacturing platforms make a real difference.
Understanding the Cost Drivers
1. Setup and Tooling
CNC machining requires fixture setup, tool changes, and programming time. These add fixed costs, making CNC more efficient for medium- to large-batch production.
Metal 3D printing eliminates tooling, so it’s ideal for complex or low-volume parts where geometry matters more than volume.
2. Material Utilization
CNC machining removes material from a block, resulting in higher waste, especially for intricate parts.
Metal additive manufacturing builds only what’s needed, optimizing powder usage and part weight.
3. Geometry and Complexity
Undercuts, internal channels, and lattice structures drive up CNC costs or make production impossible.
3D printing handles these easily but may need post-processing (machining, polishing, heat treatment).
4. Lead Times
CNC lead times vary by machine availability and tooling setup.
Metal 3D printing can be faster for prototypes but slower for high-precision production requiring post-machining.
Typical Cost Comparison Example
| Part Type | CNC Machining | Metal 3D Printing |
|---|---|---|
| Simple bracket (Al 6061) | €80–€120 | €150–€220 |
| Complex manifold (Ti64) | €400–€600 | €280–€450 |
| Heat exchanger (CuCrZr) | €700+ (multi-setup) | €450–€650 |
| Lightweight mount (SS 316L) | €250–€400 | €300–€420 |
These ranges are indicative and depend on geometry, material, and surface finish requirements.

When to Choose Each
Choose CNC for parts requiring perfect dimensional accuracy, such as housings, shafts, or precision fits.
Choose metal 3D printing when internal channels, lightweight structures, or fast design iterations are the priority.
Many engineers now combine both, printing in near-net shape and finishing with CNC for precision. MakerVerse supports this hybrid workflow seamlessly.
There’s no universal “winner” between CNC and metal 3D printing; it’s about using data to decide what’s best for your part.
With MakerVerse, you can upload your design once and get cost and lead-time estimates for both technologies — enabling more thoughtful decisions, faster.
