3DSolex CHT MATCHLESS nozzle 1.75 - 0.40 mm

Increase plastic output thanks to our patented core heating nozzles and take full advantage of the Bondtech feeder already installed in your printer. By combining nozzle size, layer height and speed you can achieve up to 30 cubic meters / second.

Available nozzles

0.25 mm (not Matchless, as the core heating has little effect on the low throughput of this tiny nozzle)

0.40 mm (Matchless; core heating)

0.60 mm (Matchless; core heating)

0.80 mm (Matchless; core heating)

The nozzles are made of brass and are coated with a layer to prevent reaction with the aluminum block.
This ensures that you can change the nozzles without destroying the heating block.

Tools

Recommended tool: Nozzle changer for Prusa I3

What it does

3D Solex CHT MATCHLESS nozzle 1.75 - 0.40 mm allows "volcano speeds" by simply changing the nozzle (0.25 mm makes no difference). The Matchless nozzles patented by 3D Solex have a much larger melting zone than a regular nozzle. A regular nozzle melts the filament from the "outside" and tries to push the coldest part (the center of the filament) through the exit hole of the nozzle.
The core heating effect of Matchless nozzles melts the center of the filament, the part you want to push out through the nozzle.

What others have to do: Extending the heating zone, which has a negative effect on retraction, is stressful on the head and is costly.

Advantages: 3D Solex CHT MATCHLESS nozzle 1.75 - 0.40 mm

1) You can now change the nozzle risk-free and without clouding by using the tool sold separately. Change the nozzle in seconds without risk of destroying the printer's sensors or causing heat disruption.

2) Print at a much higher throughput by configuring a combination of:

a) Nozzle size

b) Layer height

c) Printing speed.

3) Print at a lower temperature. Since you are effectively melting the plastic, you can print at a lower temperature than before. Using the existing settings from your previous print, you can lower it by 5-15 C.

4) Wide range of nozzle sizes (mm) available from 3D Solex:

0.25, 0.40, 0.50, 0.60, 0.80, 1.0, 1.2, 1.5, 2.0

For example, you can now print a vase with a 0.80mm nozzle at the same or higher speed than you could previously with a 0.40mm nozzle. This way, you only need 1 pass to create a 0.8mm wall.
