Prototyping and additive manufacturing

Additive manufacturing has revolutionized the way we design and produce complex components, but 3D printing is only half the process. To achieve functional, aesthetically flawless, and mechanically robust parts, the post-processing phase is crucial.

In the rapid prototyping and additive manufacturing industry, surface finishing is not just an aesthetic choice, but a technical necessity to eliminate production waste and improve material performance.

The importance of surface finish in professional 3D printing

Whether using powder bed technologies (such as SLS, SLM, DMLS) or extrusion and resin processes, each part produced requires a specific surface treatment.

The natural roughness of the printing process, the presence of structural supports and residues of sintered powder require high precision intervention.

An inadequate finish can compromise the dimensional accuracy of the component or its fatigue strength.

For this reason, integrating sandblasting and shot peening systems into the production workflow has become the standard for companies striving for excellence.

Lampugnani 3D post-processing solutions

Lampugnani designs and manufactures industrial sandblasting and shot peening machines specifically configured for the needs of the Additive Manufacturing sector.

Our machines are not simple cleaning tools, but real finishing systems that guarantee repeatability and constant control.

Our pressure systems

Removal of dust and supports

Lampugnani sandblasting machines gently remove excess powder from printed components, even from complex cavities and internal channels typical of generative design.

The process is carefully calibrated to protect delicate geometries while ensuring thorough cleaning.

Mechanical improvement

For 3D-printed metal components, such as titanium, aluminium or stainless steel parts, our controlled shot blasting technology can induce compressive residual stresses on the surface.

This process significantly improves fatigue resistance and component service life, making it suitable for aerospace, medical and automotive applications.

Finitura estetica

By using glass beads or ceramic media, Lampugnani solutions achieve perfectly uniform, satin-finished surfaces.

This treatment reduces the typical “layering” effect of 3D printing, preparing components for subsequent processes such as painting or electroplating, or simply for final use.
