Core One vs MK4S Specs
printing technology
The Original Prusa MK4S uses standard FDM printing technology. This is a proven method that delivers fast results with excellent surface quality and dimensional accuracy. It relies on input shaping to reduce ringing and vibrations, ensuring sharper edges even at higher speeds. In contrast, the Original Prusa CORE One utilizes a CoreXY motion structure. This design combines high-speed printing capabilities with maximum print quality. The CoreXY system is engineered for exceptional reliability and minimal maintenance, offering a different approach to motion control compared to the MK4S. Both are reliable, but the CoreXY design in the CORE One is built for a specific type of high-speed performance.
build volume
You get more space with the Original Prusa CORE One. Its build volume measures 250 by 220 by 270 millimeters. This larger area allows you to print bigger models or multiple smaller parts at once without repositioning. The Original Prusa MK4S has a smaller footprint, with a build volume of 9.84 by 8.3 by 8.6 inches. While the MK4S is compact, the CORE One offers significantly more room for larger projects. If you frequently print large functional parts or detailed prototypes that require more surface area, the CORE One is the better choice. The MK4S is sufficient for smaller, detailed work.
compatible material
The Original Prusa CORE One is designed for a wide range of materials. It features an enclosed chamber with active temperature control, capable of reaching up to 55 °C. This allows you to print demanding materials like ASA, PC, or Nylon, even with the door closed. It handles PLA and PETG easily as well. The Original Prusa MK4S is described as suitable for functional parts and detailed prototypes, but the data does not specify an enclosed chamber or heated chamber capabilities. The CORE One’s ability to maintain high internal temperatures makes it more versatile for engineering-grade filaments that require strict thermal management.
structure
The Original Prusa CORE One is built with an all-steel exoskeleton frame. This design provides maximum firmness and robustness, contributing to its reputation as a workhorse with minimal maintenance. The MK4S does not have a specified frame material in the provided data. The CORE One’s steel construction ensures stability during high-speed printing. This rigid structure helps maintain precision over time, especially when pushing the limits of speed. For users who prioritize long-term durability and a solid, heavy-duty build, the CORE One’s exoskeleton is a clear advantage over the MK4S.
dimensions
The Original Prusa MK4S is more compact than the CORE One. It measures 15.7 inches in width, 19.6 inches in length, and 21.6 inches in height. It also weighs 15.4 pounds, making it easier to place on smaller desks or in tighter spaces. The Original Prusa CORE One is larger and heavier. It measures 17.5 inches in width, 16.3 inches in length, and 21.8 inches in height. Weighing 56.9 pounds, it is a substantial machine. If you have limited workspace or need a lighter printer, the MK4S is the more practical option due to its smaller footprint and lower weight.
Choose the right Prusa printer for you
Users needing high-temp materials like ASA or Nylon
The CORE One features an enclosed chamber with active heating up to 55 °C. This allows reliable printing with demanding filaments such as ASA, PC, or Nylon.

Frequently asked questions
Is the MK4S faster than the CORE One?
The MK4S is designed for high-speed operation. It uses input shaping to reduce ringing and vibrations, which ensures sharper edges and faster printing cycles. The CORE One prioritizes structural rigidity and chamber heating over raw speed. You should choose the MK4S if rapid prototyping is your main goal.
Which printer is better for printing Nylon?
The CORE One is the better choice for Nylon. It features an enclosed chamber with active heating up to 55 °C. This environment prevents warping and allows for reliable printing with demanding filaments like Nylon, ASA, or PC. The MK4S is open-frame and less suited for these high-temp materials.
How much space does each printer take up?
The MK4S measures 15.7 inches wide, 19.6 inches long, and 21.6 inches tall. It weighs 15.4 pounds. The CORE One is wider at 17.5 inches but shorter in length at 16.3 inches. It stands 21.8 inches tall and weighs 56.9 pounds, making it significantly heavier and bulkier.
Does the MK4S come fully assembled?
Yes, the MK4S is a fully assembled desktop machine. It is ready to use out of the box. It includes a spool of PLA filament and lifetime technical support. This setup saves you time and ensures you can start printing functional prototypes immediately without any prior assembly experience.
What is the main difference in design between them?
The MK4S uses a standard FDM design focused on speed and reliability. The CORE One uses a CoreXY mechanism with an enclosed chamber. The enclosure provides thermal stability for advanced materials. The CORE One is heavier and built for structural rigidity, while the MK4S is lighter and optimized for fast output.
Can I use the MK4S for ASA filament?
The MK4S is not ideal for ASA. It lacks an enclosed chamber and active heating. ASA requires stable, elevated temperatures to prevent warping. The CORE One handles ASA well because its chamber heats up to 55 °C. You should stick to PLA or similar materials with the MK4S for best results.
Which printer is easier to move?
The MK4S is much easier to move. It weighs only 15.4 pounds. The CORE One weighs 56.9 pounds due to its all-steel construction and enclosed design. If you need to transport your printer frequently, the lighter MK4S is the practical choice. The CORE One is best suited for a permanent desk setup.
