Specs: Speed, Resolution, and Tech
Printing technology
The ELEGOO Centauri Carbon uses fused filament fabrication, a material extrusion method that melts thermoplastic filaments to build objects layer by layer. This approach is versatile and supports a wide range of common plastics. In contrast, the ELEGOO Mars 4 Ultra 9K Resin 3D Printer utilizes MSLA technology. This method uses a UV light source to cure liquid resin into solid plastic. MSLA printers typically produce smoother surface finishes and higher detail resolution than FDM printers. You choose filament for strength and versatility, or resin for fine detail and smooth surfaces. The core difference is the material state: solid filament versus liquid resin.
Print speed
When speed is your priority, the ELEGOO Centauri Carbon CoreXY 3D Printer has a clear advantage. It features a CoreXY motion structure that allows for print speeds up to 500 mm/s and acceleration of 20000 mm/s². This enables rapid production of larger parts without sacrificing layer adhesion. The ELEGOO Mars 4 Ultra 9K Resin 3D Printer does not list a comparable linear speed metric in its specifications. Resin printing speed is generally measured in seconds per layer. The Centauri Carbon is designed for high-throughput tasks, making it the faster option for volumetric output and quick iterations on large models.
Resolution and detail
For fine detail, the ELEGOO Mars 4 Ultra 9K Resin 3D Printer is superior. It employs a 7-inch 9K monochrome LCD with an 8520x4320 resolution and an XY resolution of 18µm. This allows for incredibly crisp details on small models, such as miniatures or jewelry. The ELEGOO Centauri Carbon CoreXY 3D Printer does not provide XY resolution data in its specs, as FDM printers generally have lower resolution than resin printers. The Centauri focuses on structural integrity and speed rather than microscopic surface fidelity. If you need sub-millimeter precision, the resin printer wins.
Build volume
The ELEGOO Centauri Carbon CoreXY 3D Printer offers a significantly larger build volume of 256x256x256 mm, which is approximately 10x10x10 inches. This allows you to print larger functional parts, prototypes, or multiple items simultaneously. The ELEGOO Mars 4 Ultra 9K Resin 3D Printer has a much smaller build volume of 6.04x3.06x6.5 inches. This size is suitable for small, detailed objects but limits the ability to print large assemblies. If you need to make large components, the Centauri Carbon is the only viable choice between these two models.
Leveling system
Both printers aim to simplify setup, but they use different approaches. The ELEGOO Centauri Carbon CoreXY 3D Printer features auto bed leveling, which automates the calibration process to ensure a perfect first layer. The ELEGOO Mars 4 Ultra 9K Resin 3D Printer uses a 4-point leveling system. While this is described as effortless, it is a manual process compared to the Centauri's automation. The Centauri Carbon reduces user intervention further by arriving pre-calibrated. For users who want the least amount of manual adjustment before printing, the automated system on the Centauri Carbon is more convenient.
Which 3D Printer Fits Your Workflow
You need large, strong functional parts
Choose the Centauri Carbon for its 256x256x256 mm build volume and CoreXY structure. It reaches 500 mm/s speeds with 20000 mm/s² acceleration. The 320°C nozzle handles advanced materials like carbon fiber. The die-cast frame ensures stability at high speeds for durable output.
You want high-detail miniatures with Wi-Fi
The Mars 4 Ultra features a 7-inch 9K mono LCD with 18µm XY resolution for crisp details. It includes Wi-Fi for file transfers and a Linux OS for smooth operation. The 6.04x3.06x6.5 inch build volume suits small, intricate models requiring precision and ease of use.
You prefer filament printing with a camera
The Centauri Carbon includes a built-in chamber camera for real-time monitoring and time-lapse videos. It arrives pre-calibrated with auto bed leveling. The enclosed chamber and high-flow hotend support reliable printing. This setup reduces frustration and ensures consistent quality for users who value convenience and visibility.
