了解 Light Processing Unit 使用寿命（Form 4 和 Form 4L 代）
In Form 4 and Form 4L generation printers, the printer’s backlight shines through the Light Processing Unit (LPU) to print. The LPU is a long-life component, and should last at least one year under average use. That lifetime may be closer to three months in a high-volume production environment. The exact lifetime of an individual LPU depends on total light energy that passes through the module, which in turn depends on the number of layers printed, material, and layer height.
如有必要，可轻松更换 LPU。该部件可在 Formlabs 商店购买，说明书可在我们的支持网站上获取。在标准保修期（或有效服务计划（如适用））内，Formlabs 将免费更换 Form 4 或 Form 4L 代打印机中任何因 LPU 故障而损坏的部件。本保修不包括用户造成的损坏，如沟槽或划痕，以及使用 Open Material Mode 打印。使用打印设置编辑器与 Formlabs 树脂配合使用不会影响 LPU 的保修范围。
