All metal hot-end group fab

[Christopher Cprek]

Hello all,

I've got the University of Louisville's Rapid Prototyping Center lined up to use their CNC lathe to make some all-metal hot-ends. I'm trying to track down some CAD files for the Prusa nozzle, but I'm interested in whatever CAD files are available. 

Would anyone be interested in a group buy for fabrication? I won't have an exact cost until I nail down a CAD design and know how many units. Obviously more = cheaper. But it shouldn't be too bad if I'm supplying the 303 stainless steel and it's only a lathe job (no additional milling).

Any interest? CAD files?

Chris

My interest hinges on price.  Less than $75? Count me in.

LvL 1 could use some metal bars for the replicators. Dr Harnett has the files and knows what she wants.

That sounds awesome.  I have not searched around for the all metal hot ends but would be interested in any designs you guys scavenge up.  Tomorrow I'll try to look at a few.  Are they just charging you tool time?

Can I get a summary of what benefits there are for the all-metal hot
end?

Sorry been out of the loop for a while, job, etc, etc.

More durable, can print at ridiculously hot temperatures (for nylon, etc.)

I would be down for one.

Do we have any approximation on how much one of these will cost?  Any luck with the CAD files?
