Case Studies
Trusted by 3D Printer Manufacturers Worldwide
Large-format CoreXY FDM printer (500×500mm)
MG9 guides used on X and Y carriages. Print speed increased to 400 mm/s with no ringing artifacts, thanks to low-friction Z0 preload.
Industrial SLA resin printer Z-axis
MG12 ZA guides used on Z-axis lead-screw stage. 0.01mm layer repeatability confirmed over 500 consecutive print cycles.
Pellet extrusion manufacturing system
HG20 selected for the X-axis of a large-format pellet printer. Handles the heavy extruder head mass with minimal deflection.
