Topic: temps with all metal hot end
What temps will the Solidoodle handle with an all metal hot-end ?
What other Materials would I be able to extrude?

Hard to say!
It depends on your extruder model. With our acrylic, it's hard to say how long it could sustain high heat before the hot-end caused damage. Then again, if you'd done the work to swap out the hot-end, you're most likely using a printed extruder model.
At some point that ABS is going to melt. Might be sooner or later. Not sure how well insulated your hot-end is.
A lot of people are talking about Polycarbonate these days. Haven't seen a whole lot of success on that front to be honest.

It depends on the hot end, and whether it is actively cooled.
With a stainless hotend and active cooling, you could push 350C no problem.
...you could extrude any material with a melting temperature less than 350C

It would be limited by its enclosure though. As the temperatures go up, you would need to add stronger components to hold the hot-end.

I specifically said with a stainless hotend and active cooling for this reason.
The temperature at the top of an actively cooled stainless hot end is within 5C of ambient. Far cooler than the passive PEEK solution currently used.

Ah yes then. I think there is a future in the metal hot-end arena.

Re: temps with all metal hot end
I seen the Prusa hotend will be shipping soon, but only comes in 3mm. Are there any 1.75 metal hotends around or being used on a SD already?
E3D-v4 Hotend, MK5 carriage with round plastic wire conduit , 3/16" tempered glass, Well nut, SureStepr SD8825 1/32 Extruder Driver, PowerEdge 2650 500W PS, QU-BD heated bed, circuit board fan, hinged plexiglass enclosure with plastic tray top. Other than that mostly stock SD3

These look great. I wonder what would happen if the fan stopped working in the middle of a print though.

Yeah, that wouldn't be pretty, I'm sure. You might want to do like Makerbot's Mk6 extruders did and add a thermal cutoff to trip a relay in the hotend power.

Re: temps with all metal hot end
Here is some photos of the one I built (untested as of yet) for 1.75 for my ORD-Bot Hadron (bowden style extruder)
I hope that the melt zone stays close to one spot so I do not get any jams when using PLA.
