[PSUBS-MAILIST] Printed Kort Nozzle

[Alec Smyth]

Hi Alan,

I like this idea! I have a printer I built myself so am a little familiar
with them. One of the parameters you provide the printers on each job
controls the "filling" of the piece. Normally, to save material that is a
sort of cross-hatch, and the parameters control things like the direction
and density of that cross-hatch. But the problem with that, for an
underwater application, is that the resulting piece is full of air voids.
I'd always assumed I would print something like this solid. However, if you
print it hollow and fill it with structural fiberglass, the end result is
going to be a lot stronger than if it's solid plastic. In addition, if we
printed by parts but filled it up once those parts are assembled, the resin
itself could be the "glue" that holds those parts together.

Thanks,

Alec
