The Formlabs Form 3L Tensioner Motor is a genuine OEM service part for the Form 3L large-format SLA printer. It drives the tensioning mechanism responsible for maintaining correct belt tension in the printer's light processing unit (LPU), ensuring the laser delivery and scanning components operate with the precision required for high-accuracy SLA printing.

A worn or failing tensioner motor can cause print quality issues including banding, layer misalignment, or irregular cure patterns on large-format prints. Replacing the tensioner motor as part of scheduled maintenance or in response to quality degradation restores full print accuracy. This part is intended for use by qualified service technicians performing authorized repairs on the Form 3L.
