Detailed Description

# ELEGOO Mars 5 Ultra

Overview

The ELEGOO Mars 5 Ultra is a compact MSLA resin 3D printer designed for high-detail printing with fast, automated operation. It combines a 7-inch 9K monochrome LCD, 18 µm XY resolution, a 153.36 × 77.76 × 165 mm build volume, and print speeds of up to 150 mm/h.

Its tilt-release system accelerates layer separation, while automatic leveling, self-check functions, smart mechanical sensing, and an integrated AI camera simplify setup and monitoring. The Mars 5 Ultra is well suited to miniatures, detailed models, jewelry concepts, prototypes, and other applications where fine surface detail is important.

For users comparing compact enthusiast resin printing with a more professional production ecosystem, the Formlabs Form 4 provides a larger build volume, automated resin handling, and a broader professional materials workflow at a substantially different market position.

Material Compatibility

The Mars 5 Ultra is designed for common photopolymer resin workflows and ELEGOO states that it supports most resins on the market, including water-washable, standard, ABS-like, and plant-based formulations.

Compatible Resin Types

Standard resin
Water-washable resin
ABS-like resin
Plant-based resin
Other compatible photopolymer resins

Recommended use: Follow the resin manufacturer's exposure, handling, washing, and curing recommendations for consistent results.

For users who need a broader professional engineering-resin ecosystem and automated resin dispensing, the Formlabs Form 4 is a more production-oriented alternative.

Print Technology and Detail

The Mars 5 Ultra uses a 9K monochrome LCD with an 18 µm XY pixel size, paired with a 405 nm COB ultraviolet light source. ELEGOO specifies 92% light uniformity to support consistent curing across the build area.

The Mars 5 Ultra prioritizes very fine pixel pitch in a compact format, while the Formlabs Form 4 uses a 50 µm pixel size with Formlabs' Low Force Display system and professional dimensional-control workflow.

Automation and Monitoring

The Mars 5 Ultra incorporates several automated features intended to reduce setup effort and detect common printing problems.

Note: ELEGOO states that AI detection results can vary depending on the environment, model, and resin type.

Its automation is focused on setup and failure monitoring. The Formlabs Form 4 adds a more integrated professional workflow with automatic resin dispensing, material recognition, PreForm, and Dashboard monitoring.

Comparison Section

The ELEGOO Mars 5 Ultra and Formlabs Form 4 both use masked resin-printing architectures, but they target very different users. The Mars 5 Ultra emphasizes compact, high-resolution and accessible desktop printing, while the Form 4 is designed around professional materials, automated resin handling, repeatability, and production workflows.

Feature	ELEGOO Mars 5 Ultra	Formlabs Form 4
Printing technology	MSLA	Masked SLA / Low Force Display
Build volume	153.36 × 77.76 × 165 mm	200 × 125 × 210 mm
Pixel size / XY resolution	18 × 18 µm	50 µm pixel size
Layer thickness	10–200 µm	25–200 µm, material-dependent
Maximum published vertical speed	150 mm/h	Up to 100 mm/h
Automatic leveling	Yes	Integrated professional calibration workflow
Camera	AI camera	Integrated 5 MP camera
Automated resin dispensing	No	Yes
Workflow	CHITUBOX, Wi-Fi and USB	PreForm and Dashboard
Best suited for	Miniatures, detailed models, hobby and education	Engineering, professional prototyping and production

Note: Resolution, dimensional accuracy, surface quality, and published speed figures are not directly comparable from pixel size or maximum vertical speed alone because the printers use different optical systems, resins, exposure strategies, and workflow assumptions.

Recommended use: Choose the ELEGOO Mars 5 Ultra when compact size, 18 µm pixel pitch, fast tilt-release printing, and accessible automated resin printing are priorities. Consider the Formlabs Form 4 when professional materials, automated resin handling, repeatability, and production workflow integration are more important.

Callout Section

Recommended use: The Mars 5 Ultra is particularly suitable for users who want fine resin-print detail combined with automatic leveling, fast tilt-release layer separation, and integrated monitoring in a compact desktop machine. For professional engineering and production resin workflows, compare the Formlabs Form 4.
