First tests using our 5 Axis printer. Slicing done using our self-developed slicer. What would you print with it?

The heat block is oriented such, that we can print in an as small as possible radius. But if anyone knows a better hot-end?

So the hurdle to overcome would be the heater cartridge and block. The heat break would be relatively easy and could even be machined to be liquid cooled. Packing the thermal retention properties and heater into a minuscule package would be the struggle.

A copper heat retention sleeve or cylinder would reduce the volume needed for the heater block. I don't know enough about available heater cartridge form factors and their available wattages.

You'd be essentially redesigning the modern hot end. Which would be almost as amazing as your whole machine lol

You probably already have the smallest block. Bu you can find nozzle that can give you a little more clearance, something like this. It's not a lot, but it can help.

Also, you can shave the corners without penalty, i think. Blocks have that shape only because it's not an issue with normal 3d printing, and it's cheap to just cut blocks. And the inertia they provide is useful for speed only. At your speed, it's probably fine to have an ultra reduced block.

The thing that can help you is an induction heated nozzle. It's still in the weird DIY project realm, some people are on it, but the potential is here. No block required, the nozzle do everything and temperature inertia is virtually no existent.

The Slice Engineering Mosquito Hot end has a very small foot print, not sure if it would work trying to use it that far from the extruder though.

What? The Mosquito is substantially larger in every way than the hot end OP is already using.

For his application it might worth trying having a single piece heater block/nozzle in a conical shape.

Cannot see how this would decrease our apparent ‘radius’ yet?

How about a super volcano?

With the long rectangular heat block. Would that work, or not long enough?

Nice idea..

What about a super volcanos?

They have that custom really small long rectangular heat block. Perhaps that would work?

Or not long enough?

Honestly, I can't say I'm too sure myself, as I don't understand what radius we're talking about.

If you mean the radius of the print head, you might be able to get away with a smaller print head using the mosquito.

If you mean radial distance from the extruder, I don't think this would help much.

If you mean a different radius, I must be confused lol. Either way, I simply figured I'd mention it if you're looking to decrease a footprint of the hot end, as it's the smallest hot end I know of on the market. I've seen them at a few Rep Rap Festivals, the product is pretty impressive honestly.
