Longer LK4
The Longer LK4 3D Printer is a compact, beginner-oriented FDM printer that still offers a useful 220 × 220 × 250 mm print area for models, gadgets, and small parts. It typically ships mostly pre-assembled with a color screen, resume-print capability, and a heated plate for better adhesion on PLA and similar filaments. As an early-generation machine in the LK line, it's often used as an affordable entry point into the Longer ecosystem.
