Post Processing of 3D Printed Metal Parts in UK to Benefit from Fintek Deal Bringing Hirtisation® to the UK

1) The H3000 is ideal for part sizes up to 300 x 300 x 150mm and can handle the part feed from up to three AM-printers

Metal component surface finishing specialist, Fintek, have become exclusive UK agents for RENA Technologies Austria GmbH patented Hirtisation® process for reliable finishing of 3D printed metal parts.

Fintek managing director, Jonathan Dean, commented, "The RENA H-series Hirtisation® process complements our existing disc, drag and stream finishing ranges from OTEC. They expand considerably our subcontract capability and machine offering for the surface finishing of additively manufactured metal parts. RENA is a global company, and we are pleased to be able to draw on their extensive experience."

The Hirtisation® process effectively removes support structures and powder cake but goes further by reducing the surface roughness of metal parts manufactured additively by 3D printing. The process is suitable for all common metals and alloys and all types of metal 3D printing technology such as Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS) and Electron Beam Melting (EBM).

Importantly, the fully automated chemical-electrochemical process is able to reach deep into cavities, undercuts and other design intricacies inherent in many AM parts and often impossible to reach by manual or mechanical methods. Along with support structures, partially melted grains are also eliminated. As there are no harsh mechanical processing steps, the smoothing effect does not compromise the precision of edge profiles.

Printed metal parts leave the machine clean and vacuum dried in perfect readiness for subsequent finishing processes such as protective coatings. Cycle times are short, from just 30 minutes depending on part size and target quality. H-series machines are easy to operate, requiring the minimum of training for personnel, even if they have little or no surface finishing experience. Designed to scale-up to any metal 3D printing operation, all process chemicals are fully integrated and can be safely refilled.

Fintek operations manager, Jamie Phillips, concluded, "Achieving a commercially viable surface finish on additively manufactured metal parts has prevented the adoption of the technology for many applications. The Hirtisation® process removes this barrier and at Fintek we also have the capability with the OTEC range of high energy stream finishing systems to take external surface roughness down to Ra values of 0.01μm."
