Longer LK5 Pro: Big Build Volume, Quiet Drivers, Easy Setup

The Longer LK5 Pro is a large-format FDM 3D printer with a 300 x 300 x 400 mm build volume in an all-metal integrated frame with dual tie rod support for stable, high-precision printing. An upgraded dual blower kit keeps overhangs and bridges clean.

It arrives 90% pre-assembled, runs from a 4.3" full-color touch screen, and uses an open-source motherboard with three sets of TMC2208 ultra-silent drivers. Resume printing and filament runout protection protect long jobs, and the carborundum glass platform releases finished parts easily.

Why the LK5 Pro

300 x 300 x 400 mm Build Volume

Room for large functional parts and full-plate batches in a single run.

Silent TMC2208 Drivers

Three sets of TMC2208 ultra-silent chipsets on an open-source motherboard keep the printer quiet.

90% Pre-Assembled

Most of the build is done at the factory, so setup is short and calibration stays true.

Upgraded Dual Blower Kit

Dual blowers improve cooling on overhangs, bridges, and fine detail.

Resume and Runout Protection

Resume printing after a power loss and automatic pause on filament runout protect your work.

Carborundum Glass Platform

The glass build platform grips while hot and releases parts easily once cooled.
