ELEGOO Centauri vs Mars 4 Ultra Specs
printing technology
The ELEGOO Centauri Carbon uses fused deposition modeling with a CoreXY motion system and a 320°C brass-hardened steel nozzle. This setup supports high-speed printing up to 500 mm/s and handles advanced filaments like carbon fiber reinforced materials. In contrast, the ELEGOO Mars 4 Ultra 9K Resin Printer is an MSLA desktop unit. It utilizes a 7-inch 9K mono LCD with an 8520 × 4320 resolution and 18 µm XY resolution. This technology focuses on high-detail surface finishes rather than speed or structural strength from composite filaments. You choose between speed and material versatility with the Centauri, or fine detail with the Mars 4 Ultra.
print speed
Speed is a major differentiator between these two machines. The ELEGOO Centauri Carbon is built for high-speed production, achieving up to 500 mm/s print speeds and 20,000 mm/s² acceleration. Its CoreXY structure and high-flow hotend allow for rapid layer deposition. The ELEGOO Mars 4 Ultra 9K Resin Printer does not list a specific travel or print speed in its specifications. Resin printing relies on exposure times per layer rather than head movement speed. While the Centauri Carbon prioritizes rapid output for larger parts, the Mars 4 Ultra focuses on precision over velocity. If you need fast results, the Centauri Carbon has a clear advantage.
build volume
The physical size of the print area determines what you can create. The ELEGOO Centauri Carbon offers a build volume of 256x256x256 mm, which is approximately 10x10x10 inches. This cubic space is suitable for medium-sized functional parts. The ELEGOO Mars 4 Ultra 9K Resin Printer has a smaller build envelope, typically around 153x95x165 mm for this model class, though specific dimensions are not explicitly listed in the provided data. The Mars 4 Ultra excels at small, intricate models where high resolution matters more than size. The Centauri Carbon provides more room for larger assemblies. You should pick the Centauri if you need larger parts.
leveling
Getting the first layer right is critical for print success. The ELEGOO Centauri Carbon features auto bed leveling and arrives fully assembled and pre-calibrated. It also includes automatic vibration compensation and pressure advance to ensure smooth first layers. The ELEGOO Mars 4 Ultra 9K Resin Printer uses a 4-point leveling system. While it claims that one leveling session lasts for subsequent prints, it is a manual process compared to the Centauri's automation. The Centauri Carbon reduces setup friction with its auto-leveling and pre-calibration. The Mars 4 Ultra requires more initial user intervention to achieve optimal adhesion. The Centauri Carbon wins for ease of use.
smart features
Connectivity and monitoring options vary between the two printers. The ELEGOO Centauri Carbon includes a built-in chamber camera with dual LED lighting for real-time monitoring and time-lapse capture. It also supports remote adjustments via its interface. The ELEGOO Mars 4 Ultra 9K Resin Printer features built-in Wi-Fi connectivity supporting both 2.4G and 5G networks. It allows file transfers at 6-10 Mbps and runs on a Linux OS with 4GB RAM for smooth operation. While the Centauri offers visual monitoring, the Mars 4 Ultra provides robust wireless file transfer capabilities. Both offer distinct advantages depending on whether you prioritize visual feedback or file management.
