The Complete Overview of the Original Prusa Core One+

The original Prusa Core One+ is more than a 3D printer—it’s a testament to what happens when engineering discipline meets open-source innovation. At its core, it’s a Cartesian-based FDM (Fused Deposition Modeling) printer with a direct-drive extruder, a heated aluminum bed, and a fully enclosed build chamber. What sets it apart is the attention to detail: the extruder’s dual-gear drive system prevents filament slippage, while the bed’s mesh design ensures even heat distribution. The printer’s frame, made from a single piece of aluminum, minimizes vibrations, and the CoreXY kinematics (a hybrid of Cartesian and delta movements) allow for faster, more precise prints compared to traditional Cartesian setups.

The Core One+ also introduced several firsts for its class. Its multi-material setup—via a tool-changing system—enabled users to print with up to four different filaments without manual intervention. The printer’s auto-calibration routines, including a bed leveling probe and a nozzle height sensor, reduced setup time to near-zero, making it ideal for both beginners and power users. Even the aesthetics reflected its purpose: a minimalist, tool-free design that emphasized functionality over flashy LEDs. For those who had grown frustrated with printers that required constant tweaking, the original Prusa Core One+ was a breath of fresh air—a machine that just worked.

Historical Background and Evolution

The story of the original Prusa Core One+ begins with the Original Prusa i3 MK3, a printer that had already earned a cult following by 2018. Josef Prusa, a Czech engineer and entrepreneur, had spent years refining his designs, and the MK3 was the culmination of that effort: a printer that was faster, more reliable, and easier to assemble than anything else on the market. When Prusa Research announced the Core One+ in 2019, it was clear they weren’t just iterating—they were reimagining the desktop 3D printer for a new era.

The transition from the MK3 to the Core One+ wasn’t just cosmetic; it was a fundamental shift in approach. The MK3 had been a labor of love, built with off-the-shelf components and a DIY ethos. The Core One+, however, was designed from the ground up with manufacturability in mind. Prusa Research collaborated with industrial partners to source higher-quality materials, such as the aluminum frame and the precision-machined extruder components. The result was a machine that could be assembled in under an hour—without requiring soldering or complex adjustments. This focus on accessibility didn’t come at the expense of performance; if anything, it elevated the Core One+ to a new tier of reliability.

Core Mechanisms: How It Works

Under the hood, the original Prusa Core One+ is a study in mechanical efficiency. Its CoreXY kinematics, for instance, replace the traditional X and Y axes with a system where the X and Y motors control the print head’s position indirectly. This setup reduces the mass of moving parts, allowing for faster acceleration and deceleration without sacrificing precision. The direct-drive extruder, meanwhile, eliminates the need for a Bowden tube, which can cause filament sagging and pressure loss—critical for printing with flexible or high-temperature materials.

The printer’s auto-calibration system is another standout feature. The bed leveling probe, combined with the nozzle height sensor, ensures that the print head maintains a consistent distance from the bed, even as it compensates for slight imperfections in the surface. This level of automation was rare in 2019 and remains a hallmark of the Core One+’s ease of use. Additionally, the printer’s fully enclosed build chamber helps maintain a stable temperature, reducing warping and improving adhesion for materials like ABS. Every component, from the stepper motors to the firmware, is optimized for one goal: producing high-quality prints with minimal user intervention.
