Additive manufacturing adoption continues to accelerate across aerospace, defence, medical and energy sectors. Manufacturers now rely on AM for functional and safety critical components, yet many still struggle to scale into full production.

The reason is simple. Finishing processes have not evolved at the same pace as printing technology.

Surface roughness, trapped powder, internal features and fatigue performance all create uncertainty. In regulated industries, uncertainty delays qualification and production scale.

Why Scaling Remains Difficult

Industry data from Wohlers Associates and Additive Manufacturing Research shows continued global growth in AM systems and materials.

However, widespread industrial deployment depends on:

• Repeatable surface finish

• Reliable internal channel processing

• Controlled de powdering

• Certification ready traceability

• Consistent fatigue performance

Traditional abrasive methods struggle to meet these requirements. They remove material unevenly, damage delicate geometries and cannot reliably access enclosed features.

That technical limitation slows production scale.

The Post-Processing Constraint

Confidence in AM does not depend on how well a part prints. It depends on how reliably that part reaches production ready condition.

When finishing requires heavy manual intervention, manufacturers face:

• Increased labour costs

• Longer lead times

• Inconsistent results

• Reduced scalability

• Higher rejection rates

Complex lattice structures and internal cooling channels make the problem worse.

A Geometry Safe Alternative

Holdson addresses this challenge with controlled electrochemical polishing.

Our systems remove material uniformly at a microscopic level using a non contact process. Instead of mechanically forcing media against the component, we control the surface reaction itself.

This enables:

• Internal channel polishing

• Reliable de powdering

• Improved surface consistency

• Reduced manual handling

• Improved fatigue performance

You can explore our electrochemical polishing technology here.

Supporting Certification and Fatigue Performance

Surface integrity directly influences fatigue life. Research published in Additive Manufacturing Journal demonstrates the relationship between surface condition and fatigue behaviour in metal AM components.

By improving consistency without abrasive damage, manufacturers strengthen performance and reduce certification risk.

That confidence enables broader production scale.

Moving from Prototype to Production

Scaling AM requires reliable finishing, controlled processes and reduced variability.

We help manufacturers move beyond isolated trials and into repeatable production by reducing rework, improving consistency and supporting traceable process control.
