ELEGOO 7 9K Mono LCD Key Specs

Screen Resolution 8520 × 4320

This pixel count defines the total sharpness of the image projected onto your resin. Higher numbers mean finer details in your prints. You get clearer text and smoother curves on small models. This spec is critical for miniatures or jewelry. Compare this with lower-resolution screens to see the difference in surface quality and layer definition.

XY Resolution 18 μm

This value measures the smallest detail the printer can resolve on the X and Y axes. An 18 μm figure allows for very precise edges. You benefit from reduced stair-stepping on angled surfaces. This is ideal for high-detail projects. Check this number against other screens to ensure it meets your precision needs for intricate designs.

Mono LCD Screen

Mono screens use a single LED wavelength for curing. This design typically offers faster print speeds than color LCDs. You save time on each layer exposure. The technology is more durable and consistent over time. When shopping, choose mono for speed and longevity. Color screens may be cheaper but often print slower and degrade faster.

Lifespan Up to 2000 hours

This rating indicates how long the screen lasts before UV damage degrades performance. A 2000-hour lifespan means you print more parts before replacement.
