Product Details

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 vacuums, sometimes followed by 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 flushing process excels.

The Guyson ‘Orbit 600 RPF’ is based on the company’s Orbit 600 rotary basket spray wash unit, 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 to the left of the machine 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 workpiece to the directed flushing jets close to the trabecular surface thus ensuring thorough powder removal. Timed electronic door interlocks prevent the door from opening during operation and until hot steam has dissipated at the end of the processing time. Also being generally installed in a production cell, the machine is equipped with process alarm signals with audible and visual cues via an Andon beacon to show the end of parts process. Completing the system is fluid level sensing and advanced filtration, fitted to the rear of the unit.
