![]() The extruder is attached to the print head assembly on a direct drive setup. With less weight on the print head, Bowden printers tend to be quieter as the stepper motors don’t have to work as hard during travel movements. Cleaner surfaces and less ringing at higher print speeds are also a benefit. With more efficient acceleration/deceleration and less jerk, the printer moves with more precision and is less prone to layer inconsistencies. A lighter print head translates to smoother travel movements. With a Bowden setup, the extruder is fixed to the frame, which reduces the weight load on the print head. Now that we have a basic understanding of what sets these two extruder setups apart, we’ll explore their pros and cons: Speed Popular Bowden printers: Ender 3, Voxelab Aquila, Anycubic i3 Mega S, Prusa MINI+ Consequently, the path between the extruder and hot end is much longer with a Bowden extruder, but the print head weighs much less. The extruder feeds filament to the hot end through a lengthy cut of PTFE tubing, known as a Bowden tube, hence the name. In a Bowden extruder setup, the extruder is generally mounted away from the print head, typically on the printer’s frame. Popular direct drive printers: Anycubic Kobra, Prusa i3 MK3S+, Artillery Sidewinder X1 What Is a Bowden Extruder? In a direct drive system, the extruder is attached to the print head assembly and feeds filament directly into the hot end, hence the name ‘direct’.Ī direct drive system has a much shorter path between the extruder and the hot end, but the print head has to carry around more weight. They serve the same basic function but come with their own set of benefits and downsides. When we talk about direct drive and Bowden, we are referring to the extruder system, specifically the mounting location of the extruder and how this affects how it feeds filament into the hot end.
