Guyson 'Powder Flush' For Cleaning Additive Manufactured Medical Implants
Increasingly the world's orthopaedic manufacturers are turning to additive manufacturing to drive the long term change in the increased complexity of medical implant design and demand for tailor made patient-specific solutions (rather than one-size-fits-
These new additive manufactured orthopaedic implants are typically made by SLS, SLM or EBM processes (Selective Laser Sintering, Selective Laser Melting or Electron Beam Melting) from Titanium powders in the size range of 5 to 45 micron for the SLS and SLM processes; and utilising 45 to 90 micron for EBM. After manufacture, the implants then have the bulk of the residue powder removed from the build block with brushes and vacuum's, sometimes followed with an air-wash or blast process to remove any semi-adhered powder particles, but because of the nature of the porous trabecular structures, small residues of powder are often still trapped inside the component and this must be removed. This is where the Guyson Powder Flush process excels.
The Guyson 'Powder Flush' is based on the company's Orbit 600 rotary basket spray washer, built in full stainless steel 304 construction, fitted with a 100 litre insulated tank and hot spray flushing facilitated through a high flow rate and pressure pump fitted with viton seals. The machine offers directed jets for powerful component flushing followed by compressed air-wash. A PLC/HMI control panel provides data monitoring and timed pre-heat function ensuring accurate and repeatable process operation. LED interior lighting and a double glazed viewing window, in the lid, facilitates visual checks on parts in process.
In operation the implants are individually or batch loaded on none contaminating fixtures presenting the work piece to the directed flushing jets in close proximity to the trabecular surface thus ensuring thorough powder removal. Timed electronic door interlocks prevent the door opening during operation and until hot steam has dissipated at the end of the process time.
