In 3D printing, the method of filament delivery to the hotend is categorized into two primary systems: one where the extruder motor is directly coupled to the hotend, and another where the motor drives filament remotely through a Bowden tube. The former offers greater control over filament movement, ideal for flexible materials, while the latter, with its lighter print head, allows for faster printing speeds and intricate movements.
The evolution of these systems has significantly impacted 3D printing capabilities. Choosing the appropriate system is crucial for optimizing print quality and speed. The direct approach allows for responsive extrusion, minimizing issues like stringing and oozing, particularly beneficial for flexible and specialized filaments. The remote approach, by reducing the mass of the print head, enables quicker acceleration and deceleration, reducing print artifacts and increasing overall print speed. This characteristic is highly advantageous for complex geometries and detailed prints.
