THE MICROFLUID TECHNOLOGY APPLIED TO ADDITIVE MANUFACTURING

The surface finishing in AM of metal parts, After de-powdering and surface preparation

After depowdering of metal components produced with DMLS, SLM, LPBF or similar process, it is a «must» to follow up with a suitable Surface Preparation and, immediately after, with an accurate Surface Finishing. VibroBLAST technology is normally the first step to follow for two reasons:

• The highest peaks of the rugosity are reduced, thus preparing the surface for its best following «accurate finishing» with a reduced time;
• Small «droplets» of hardened powder still remaining sticked to some points of the surfaces, are easily removed, leaving the geometry of the component as required by the original 3D drawing;

The surface finishing in AM of metal parts, Must first follow a suitable surface preparation

When metal components have high rugosity and sizes are of medium small size, it is the correct condition to prepare them using the innovative VibroBLAST Surface Preparation technology.
IntegrAM has designed and produced automatic VibroBLAST systems to save a big volume of time by launching automatic cycles based on recipes.
One example is given by the «case study» approached in cooperation with the digital platform SF4T – Surface Finishing For Target

The final result after MF finishing, is the best «start» for further precision steps

• After the final result of the MicroFLUID finishing process has assured constant results with:
•  Extremely smooth surfaces
• Very reduced rugosity
• Homogeneous and repeatable results

It is possible to forecast the final precision machining of the areas where the needs of final manufacturing are very high levels, or further steps, such as ultrasonic washing, electrochemical cleaning, and so on.
