I've been 3D printing parts at Estes for 9 years. A 3D printed fin done on the machine at work wouldn't hold up long enough for me to use for a Scale Model I intend to enter at NARAM. I do a little of every type of modeling. Some of these parts I can craft by hand, some I can use a 3D printer for, then turn these into masters and then cast a part out of resin or if needed make a hollow fiberglass part. Below is a link to my first GOA where some of the parts were 3D printed, then cast and some were created out of wood, then cast.

So I personally am fine building a model any way I can. Oh and by the way I just purchased my own 3D printer for home use and I do intend to see how it prints some of these parts out.

It will be too heavy for BP motors so it will most likely use F composite motors in both stages.
