If you own a Creality CR-10, CR-10S, CR-10 Mini or Ender-3 (any version up to V2), this advanced modification can revolutionize the quality of your 3D prints. Wade Direct Extrusion Conversion, represents the ultimate upgrade for:
Dramatically improve print quality.
Almost completely eliminate annoying hotend blockages.
Achieve more precise and consistent extrusion.
Print more demanding materials such as TPU with greater ease
The advantages of the Wade system definitely outweigh some small limitations of this technology, due to a small increase in the weight of the extrusion system. To limit weight, we can optionally replace the original Nema 17 engine, with a more compact and lighter one like the Nema 14.
Pros and Cons of the two remote and direct extrusion modes.
The substantial difference between the two extrusion systems concerns the positioning of the Nema motor in the 3D printer.
While in the Wade system the motor is positioned directly above the hotend moving in a solidary way with the trolley, The Bowden remote system, on the other hand, is mounted separately at a fixed point on the 3D printer, So the filament arrives at the hotend with a fairly long path through a Teflon tube.
The main advantage of the Bowden is the low inertia of movement of the extruder along the x-axis. This characteristic becomes all the more important when the extruder makes fast movements subject to significant accelerations and decelerations. While the most negative aspect of this approach concerns the need to apply a higher force to achieve extrusion. This is due to the considerable distance with the hotend, in fact, a part of the thrust that the filament receives from the driver is lost along the sheath.
However, this technique allows us to significantly lighten the carriage allowing us to make faster and at the same time relatively more precise prints. In fact, since the motor and the extrusion driver are mounted in a remote position outside the carriage, the latter will have a very low weight and consequently its small inertia will allow it to move faster and more precisely.
The Wade being directly connected to the hotend and then mounted on top of the cart, it has greater weight and inertia. However, practical tests have shown that the weight obtained does not represent a serious limitation for printing.
The main disadvantage of an extruder is precisely the fact that the greater weight increases inertia on acceleration and deceleration. Instead, on its side we have that all the energy will be transmitted to the filament which will thus be able to escape with more force in the hotend.
In addition, the Wade system can be further improved by reducing its overall weight and consequently also inertia. In essence, it will be enough to replace the original Nema17 engine with a more compact and lighter one like the Nema14.
