Re: [CAD_CAM_EDM_DRO] Re:3D Printer Fun (and Santa Claus :-)

I have to admit that the UV cure stuff does take a bright Light, I've
worked with both the Semiconductor stuff & Locktites UV cure for fiber
winding. The fiber winding version gives you most of the advantages of a
PrePreg at a lower cost, The also have a resindip & UV cure system for
finish coating stuff. Entec sold a fab line to a Japanese company for
compressed gas cylinders that used the UV cure stuff for both the windin
& finish coat.
On a different note if you could keep the head from clogging, you could
try a Cyano acrylic resin (Crazy glue) and microballoon system, I've
used it to make fillets in model aircraft.
