Printing with a 1.5mm 3D Solex, but it's also 3mm filament.
I'm not fully dialed in, but getting some insane rates, example being printing 243g of filament in 3hours and 31 minutes.
The same print, had I used a 0.4mm nozzle and 0.2mm layer height to get about the same wall thickness (number of shells and layers for roofs and floors) to get near the same density 227g, would take 17+ hours.

What I'm saying is, regardless of filament size, #1 3D Solex nozzles are a game changer, and #2 bigger is better, and while I might have some resolution and details to work through, if you are printing big and need it done and strong prints, this is where you really see some melting plastic.

Again, let's say you had an N2Plus and you have some really big prints that take up near the full bed size and are 600mm tall. That kind of print job could take a week with a 0.4mm nozzle, running as fast as you could push the mechanics, simply because the layer height and how wide a nozzle pass is, to push that kind of volume. You use that larger 0.8, 1.0, 1.5mm nozzle, or even the 2.0mm nozzle, You could print in a day what you cannot print in 5 days with a 0.4mm nozzle.

Also, I have an ABS profile for a 0.8mm Solex nozzle from Vice Chief that prints OK, but the truth is, we got much better results from S3D with these larger nozzles. This was used on My N2 plus with a Bondtech and normal 1.75mm filament.
The slicing settings don't change, the only place where 3mm is set is in the machine profile.

Again, sorry if I'm not giving the exact answer you wanted, but I can say this, #1 I ordered the same 3D Solex nozzle set for the Raise 3D printer. #2 I'm using a Bondtech extruder on most of my printers, just not the biggest machine running the 3mm filament (that runs a Titan Aero), but I am running 3D Solex "Matchless" nozzles on all my printers in testing now. I bought my kit of nozzles here after Martin of Bondtech showed his demo kit to me at MRRF https://www.amazon.com/3D-Solex-Raise3D ... B074M75CVK


This is the marketing information, but I'm telling you my real world testing absolutely says this is not just some fancy numbers, it's true.
Sizes 0.25- 2.0mm Worlds Biggest Nozzle for Raise3D.

Prints up to 4 times more output.*
Prints cooler, – 5-15 deg Celcius.*
100% drop-in compatible
-Matchless Race Technology prints up to 4 times faster then a standard nozzle of the same size.*
-Hard metal coated Brass. Makes for easier outside cleaning.-Precision manufacture in Norway at an ISO 9001 certified facility.
* -does not apply to 0.25mm and as this small size does not benefit from the Matchless technology.
* – 0.40mm not available yet.

Usage suggestions, adjust speeds up / down form here:

Greatly increase plastic throughput according to this formula. In many applications you can benefit from printing an equally low layer as before, but several times wider so you need fewer passes since the wall will be 1-2mm thick just by one pass.

Nozzle size (mm) X layerheight (mm) X printing speed (mm/sec) = cubic mm plastic/sec.

0.60 nozzle example: 0.60 x 0.15 x 150 = 13.5 cubic/sec.
1.0 nozzle example: 1.0 x 0.3 x 100 = 30 cubic/sec. ( already world record for Raise3d).
2.0 nozzle example: 2.0 x 1.0 x 40 = 40 cubic/sec. ( !! ).
2.0 alternative xample: 2.0 x 0.15 layer x 100mm/sec = 30 cubic/sec.

Using a BONDTECH feeder for Raise3D can significantly increase these figures, on some cases up to double ore more, depending on your filament, model, and printer/slicer settings.


One of the reasons is, they use 5 axis CNC machining to make a greater surface area contact to help melt the filament.

Hi JetGuy. I have not been able to get a decent enough looking print with the Matchless nozzles. I have spent many hours - days actually - adjusting and still cannot reduce artifacts to an acceptable level. However, when I want to make something fast and quality is not a major issue, the matchless nozzles are the way to go for sure. I made a Digital Read Out bracket for my lathe at 100mm/sec and it came out far better and faster than the stock 0.8mm nozzle could ever do. So they have their uses for sure.

I'm printing my prototypes in Hatchbox ABS white with a 0.6mm nozzle and I thought that maybe I could speed things up with the Matchless, but no -- at least not without sacrificing too much quality. Let me know if you can beat the quality issue -- that's the hangup with these in IMO. I may apply the Lin_Advance to the problem - just thought of that. I believe the problem has to do with the acceleration and deceleration vs. the curve of the pressure in the nozzle as the problems all come at the corners/turns/shell levels.
