What is a hot end 3D printing?

The hotend can be described as the component of an FDM 3D printer that heats, melts and extrudes the material layer by layer through a nozzle. The whole structure of the hotend helps to maintain a consistent and accurate temperature as well as providing an optimized thermal dissipation.

What delivers the material in a 3D printer to the hot end of the nozzle section?

In a nutshell, FDM involves feeding a thread of plastic material into a hot metal block with a nozzle. The filament melts, and the printer’s movements deposit it in the desired shape.

What is a BMG extruder?

A Bondtech mini-geared extruder (BMG) is a high-quality extruder from the well-known Bondtech, which specializes in 3D printer extruders, nozzles, and other accessories. The extruder has a power-increasing gear ratio for its dual drive setup and comprises many high-quality components from strong materials.

What is direct drive extruder?

The direct drive extruder (A) is installed with the hotend (C) and pushes the filament (B) directly into the nozzle (D). All filament processing components are therefore located in one place on the print head. This creates advantages and disadvantages that you should consider before buying a printer.

What hot end does Ender 3 have?

What hot end does the Ender 3 have? The Ender 3 has a stock Creality hot end. It can reach temperatures between 255°C and 260°C and sports a 0.4 mm nozzle suitable for 1.75 mm diameter filament. The assembly is standard for low-cost printers, centered on a PTFE tube running through a heat sink capped by a heat break.
