Group: Forum Members Posts: 6, Visits: 13	HI, I new to prepeg and want to try to make some parts without a mold, but instead use a 3D printed part core. I´m going to make a hydrofoil wing that is about 600mm x 150mm. The idea is to 3D print the core and then put on vari-preg 430 very carefully and trim to trailing edge of wing with precise overlapp, then a layer of easypreg with gloss layer out, and trim carefully. Then cover with release film- again with no wrinkles. Put it into V-bag and cure oven. I want to avoid any major grinding or sanding to avoid changing the wing profile- i would like to be able to only sand the trailing edge /fiber overlapp. and go directly to sand to 400-600-800g matt finish. Do you think this is possible ?

I have made a number of hydrofoils with a similar technique but I used a CNC solid fibreglass core...
