Resin 3D Printer Elegoo Mars 5 with 4K LCD resolution

ELEGOO Mars 5 3D Printer is a resin MSLA printer with a 4K 6.6-inch monochrome LCD designed for high-detail prints. The Mars 5 provides a working volume of 143.43 x 89.6 x 150 mm, 35 μm XY resolution and layer thickness from 0.01 to 0.2 mm, making it suitable for miniatures, prototypes, jewelry and other applications where fine surface detail and dimensional accuracy are required.

Advantages

The Mars 5 features automatic leveling and a One-Click Self-Check to reduce setup time and prevent failed prints. An intelligent mechanical sensor monitors resin level, detects residue and signals leveling errors to protect the LCD and maintain print quality. The printer uses a COB 405 nm light source, a 4K Mono LCD for precise XY resolution, and includes overheat protection that halts operation if the LED temperature exceeds 80℃. The device is compact and includes a complete accessory kit.

Suitable for

• Detailed miniatures and tabletop models
• Jewelry prototypes and small decorative parts
• High-detail prototypes and product concept models
• Dental models and other medical mock-ups requiring fine detail
• Hobbyist and small workshop production of parts with fine surface finish

How to use

Install the Mars 5 on a stable, level surface and connect the power supply. Load compatible resin into the resin tank and secure the work plate. Use the automatic leveling function and One-Click Self-Check before the first print to verify alignment and system status. Prepare and slice models with supported software (Chitubox or Voxeldance Tango), export to USB and start printing via the printer's USB interface. Monitor prints for the first layers to confirm adhesion and check resin level periodically during long jobs.

Usage recommendations

Use recommended resins for best results and mix or filter resin if reusing. Keep the LCD protection film clean and replace the PET film if damaged. Allow prints to fully post-cure according to resin manufacturer instructions. Observe safety precautions: use gloves, maintain ventilation, and clean resin spills immediately. Do not operate the printer if LED temperature warnings appear; allow the unit to cool before restarting.
