Two Quadrax systems were sold. One was sold to Magna Engineering in Ft.
Walton Flordia...contact Greg Medla at 904-243-9599....Greg can supply all
the answers you may have concerning the process and machine operation. He
does not have an email address. Greg was also in the first 3D systems
training class representing General Motors.
When 3D Systems won it's lawsuit against Quadrax they also acquired the
patents that Quadrax possessed including the re-coating process. You may
wish to contact 3D Systems concerning the process.
just a bit of history.....
