The hot end is a crucial component of a Fused Deposition Modeling (FDM) 3D printer responsible for melting and extruding thermoplastic filament. It typically consists of a heated block, a nozzle, and a heat break that work together to ensure precise temperature control and material flow. This part is essential for producing high-quality prints by allowing the filament to be heated to its melting point before being deposited layer by layer onto the build surface.
congrats on reading the definition of hot end. now let's actually learn it.
