Prusa I3 Nozzle Speed Doubler

Included in kit:

Nozzles

0.25 mm (not Matchless, as the core heating will have little effect at 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 brass, and are coated with a layer to prevent them from reacting with the aluminium block.
This ensures that you can change nozzles without fear of destroying the heater block.

Tools

Nozzle Changer to hold hot end for Prusa I3.

What it does
This kit allows “volcano-speeds” by just changing the nozzle. The Matchless nozzles, patented by 3D Solex, have a melting zone much bigger than an ordinary nozzle. An ordinary nozzle is melting the filament from the “outside” and trying to push the coldest part (centre of filament) through the exit hole of the nozzle.
The core heating effect of the Matchless nozzles is melting the middle of the filament, that part which you wish to push out through the nozzle.

What the others must do: Lengthening the heating zone, which has a negative effect on retractions, adds weight to the head and is costly.

Advantages
1) You can now change nozzle risk free and hassle free, by using the tools included in this kit. Change nozzle in seconds, without risk of destroying the sensors of the printer or the heat break.

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

a) nozzle size

b) layer height

c) printing speed.

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

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

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

Example: You can now print a vase with a 0.80mm nozzle at the same or higher speed than you could using a 0.40mm nozzle previously. This way you only need 1 pass to make a 0.8mm wall.
