Is dual gear extruder better?

Is dual gear extruder better?

A Dual Drive extruder replaces the idler wheel with a second “hobbed” drive gear, gripping the filament from both sides for greater control. Dual drive is superior, and a core feature of the “next generation” extrusion systems, but aren’t necessarily a must have for everyone.

Are dual extruders faster?

A dual extruder printer is faster because it eliminates the lengthy process of swapping out one filament for another. Dual extruder printers allow you to use water soluble PVA filaments for support structure, meaning they can just be washed away with water once an item is fully printed.

How do you remove extruder gear?

Some Creality machines have press-fit extruder gears. These usually pull right off with standard pliers but adding some WD-40 to the top of the gear/shaft and letting it set up for 5 minutes will usually loosen it up quickly.

Does the Ender 3 V2 have metal extruder?

Creality Upgraded Ender 3 v2 Ender 3 CR-10 3D Printer All Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Ender 3 Pro/Ender 5/ CR-10 Series.

How do you remove gear from shaft?

The best way to remove worn out gears or bearings from a shaft is to pull them off using a gear puller. These have arms that hook behind the gear or bearing and a centre screw. They are available at any local auto store and come in various sizes and designs.

Why are there two gears in a dual drive extruder?

Two gears joined to the drivers are responsible for the dual drive characteristic: the filament is griped in two sides at same time. But there are some objections to this design (and to the designs of direct drive extruders as well).

How does a winsinn dual gear extruder work?

1) Assemble everything but do not lock the motor drive gear to the shaft. 2) Using a couple pieces of paper, shim the idler drive gear in the center of its bracket. 3) Clamp a piece of filament in the drive grooves and turn the motor a few turns. This should locate the motor drive gear in the correct position.

Can a geared extruder reach high print speeds?

The Flow Rate of an extruder is one of the main issues to reach high print speeds. Trying to push the limits of flow rate in direct-drive extruders leads to motor stall or filament smashing. A geared extruder, as Wade’s, increases the torque available to the hobbed drive. The motor is less prone to stall, but smashing filament is still an issue.

Can a planetary gear box increase extrusion rate?

A planetary gear box should be able to eliminate the radial force over motor shaft and increase the extrusion flow rate, but with that, things start to became expansive. There is another objection to this design: The distance between gears depends on the filament hardness.
