The texture on the top of the LPU reduces forces on the printed parts, resin tank, and
printer between layers. Maintain a clean LPU to prevent print failures and damage to the
resin tank. Refer to section 6.6.5 Cleaning the LPU release texture for more information.
• Platform lock
A lever that is part of the locking mechanism that secures the build platform. Contact
Formlabs Support or a certified service provider before adjusting the platform lock, as
improper adjustment can lead to damage to the machine.

The Z-axis lead screw is a threaded rod that controls the vertical motion of the build platform
mount. Keep the lead screw clean and well-lubricated so that the build platform mount can
move smoothly and accurately. To inspect and lubricate the lead screw, refer to section
6.5.5 Maintaining the Z-axis screw.
