<div dir="ltr">Hi Alan,
<div><br clear="none">
</div>
<div>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.</div>

<div>I was re thinking your idea of a printed Kort nozzle.</div>
<div>There are printer kits for $900- that would do the job.</div>
<div><a rel="nofollow" shape="rect" target="_blank" href="http://www.3dstuffmaker.com/">http://www.3dstuffmaker.com/</a><br clear="none">
</div>
<div>The ABS printer cable I've seen selling for about $1- an
ounce.</div>
<div>The $899- version in the above link could possibly be big enough to
print</div>
<div>the nozzle in one shot. If not then print it in sections & glue
together.</div>
<div>My idea is to print the nozzle hollow with an egg shell wall
thickness & fill it with</div>
<div>a fiber reinforced epoxy resin. The resin may need a few pours to
allow for contractions</div>
<div>in the resin while setting.</div>
<div>Maybe under $30- in materials.</div>
<div>I am not at the point where I need this & neither are you, but
I think this idea still</div>
<div>holds a lot of promise.</div>
