Tungsten Alloy Nozzle?  

RE: Tungsten Alloy Nozzle?

I believe the E3D Volcano is a pretty easy changeover on the Prusa Mk3. It would allow for a higher  volumetric  flow  rate  and  hence faster printing - especially Polycarbonate which loves printing in big wide lines from a 0.6 nozzle. 
I have yet to try the Volcano but it’s on my to todo list. 

RE: Tungsten Alloy Nozzle?

Do consider e3D's nozzle x a high temp hard nozzle but which has some sort of coating that prevents the filament from sticking to it.

I am getting much improved results with this.

RE: Tungsten Alloy Nozzle?

I have a set of TC nozzles from DyzeDesign and am using them with my Mosquito. They seem to be the same length as Slice's vanadium nozzle and don't have the recess of the EV3D.

RE: Tungsten Alloy Nozzle?

Do you have to use hotter temps to compensate for the material on the nozzle x? I wanted to avoid that, hence why I'm looking into tungsten.

RE: Tungsten Alloy Nozzle?

From what I've found

- NozzleX:  Good nozzle, print anything, love the non stick coating, same dimensions as other std E3d nozzles but poorer thermals.  I had to raise temps by about 10c

- TC:  Great nozzle, print anything, dimensions are different so you have to re-Z, thermals the same as brass (so no changes in temp required).  Only thing I'd love to see is a non stick coating version (not that blobs are that much of an issue but it would be improved by a coating).

I also spoke with E3D to see if they were making a TC Nozzle but they have to plans to make one.

Love my TC.  Mine is this one but they are out of stock - https://www.ev3dm.com/product/tungsten-premium-nozzle/

I think my TC nozzles are the same dimensions as the E3D. I didn’t need to change my Z offset but did a re-calibration anyway. Here’s my new setup for printing CF reinforced nylon. - Spool 3D TC 0.6 nozzle, modified food dehydrator and some PTFE tubing and fittings. 
I’ve noticed that the TC nozzle seems to be quite non-stick, even with PETG. Not as clean as the Nozzle X though. 

RE: Tungsten Alloy Nozzle?

Should I go with the Spool 3D variant or the EV3DM?

I think tungsten itself is somewhat inherently non stick. That's why it's used on cutting tools. 

RE: Tungsten Alloy Nozzle?

Having both here, I would recommend the Spool3D one because of its geometry match to a standard E3D nozzle. 

RE: Tungsten Alloy Nozzle?

Was kind of leaning toward that. Now for the size.

Any issue printing Prusa MK3S upgrade parts with a .6mm nozzle versus .4mm?

I would not advise using a 0.6 nozzle for printing parts that are dimensioned for 0.4 nozzle printing. You will end up with parts with perimeter sizes (both internal and external) that differ from design intent. Internal perimeters like bolt holes will be slightly too small. Outer perimeters will be slightly larger. If you want to print replacement parts, temporarily swap to a 0.4 mm brass nozzle if you care about things fitting together. The filament sensor pocket and lever are definitely places you don't want to alter the dimensions. You might get away with it, but it's not a good plan.

I've printed Prusa replacement parts with a 0.6 Nozzle, but as guy-k2 says, it leads to dimensional issues with holes and other perimeters.  OK for simple parts where you can make some adjustments with a file but best to use a 0.4 for anything where dimensions are critical.

I printed a replacement extruder idler cover in PETG using a 0.6 nozzle because I was being lazy and already had the PETG loaded in that machine.  I needed to file out the holes a little to make it work properly.  Captive nut was tight but worked OK.  A set of modeller's files can be very useful.  Next time I will use the 0.4 nozzle.

Guy - you mention you have used the spool3d.ca variety .. they don't show the ID of the filament bore. Is it 1.75 or 2.0 mm or something else?

Tungsten carbide is a carbide and will have nearly identical thermal conductance of brass.

RE: Tungsten Alloy Nozzle?

Yikes!.

I tried to order a Tungsten Carbide nozzle from Spool3d, to the UK.

They want $56 for shipping!!!!!.

I'm afraid, I shan't be buying one yet.

RE: Tungsten Alloy Nozzle?

That one looks like a steel - Tungsten Carbide hybrid though. I’m unsure of whether that makes much of a difference. 

RE: Tungsten Alloy Nozzle?

It was $37 to Australia, so not cheap.

The mention of steel in the "Unbeatable price/performance" box is weird, as there's no mention of steel elsewhere. I have three of these nozzles and they work great.

RE: Tungsten Alloy Nozzle?

I'd avoid the hybrids. Get a one piece. I'm sure they work fine, but I'm sure the one piece will last longer in the long run and stay more consistent

RE: Tungsten Alloy Nozzle?

Does anyone have experience with the TC nozzle sold on 3DMakerEngineering?

https://www.3dmakerengineering.com/products/tungsten-carbide-3d-printer-nozzle?_pos=2&_sid=015730736&_ss=r

It looks really similar to the one from Spool3D...

I have used both the TC from 3DMakerEngineering and Spool3d.  I have not tried DyzeDesign's nozzles.  They are next on my list.  

I prefer the Midwest TC Nozzle.
