[PSUBS-MAILIST] Printed Kort Nozzle

[hank pronk]

Alan,
this may be a dumb question,,, why not use liquid plastic.  The stuff I use is strong and shrinks almost nothing.  It also does not generate heat when curing.  This stuff is the harness of a hockey puck.

To interested parties,
I spoke with a 3d printing expert, Richard, regarding filling hollow sections of 3d printed items with
fiber reinforced resin. He hadn't heard of it, but thought it had a lot of potential.
He suggested watching out for heat generated in the exothermic reaction, as we had already
discussed, and printing a roughened interior surface as a key for the epoxy, to stop the exterior 
delaminating.
I also spoke to an epoxy tech who told me epoxy only shrinks about 1/2% & with additives such as
milled fiber the percentile shrinkage of the whole will decrease proportionate to the additive.
So shrinkage may not be a major problem.
Will do some experimenting.
