In a move that challenges the industry’s trend of planned obsolescence, Prusa Research has announced a sweeping update to its entire current lineup of 3D printers. The company has officially introduced a "plus" designation for its most prominent machines—the XL, Core One, and Core One L—marking a significant second-generation evolution for these platforms. This transition represents more than just a minor hardware refresh; it is a fundamental shift in how the Czech manufacturer intends to support its users long after the initial point of sale. The Core Announcement: What the "Plus" Means Effective immediately, all new orders placed for the Prusa XL, Core One, and Core One L will ship with the new "plus" specifications. In a consumer-friendly gesture that bucks the current economic trend, Prusa Research has confirmed that these upgrades come at no additional cost to the customer. Even those with existing orders currently in the fulfillment pipeline will be upgraded to the "plus" version automatically, ensuring that early adopters and new buyers alike benefit from the latest engineering refinements. For current owners who are not in the market for a new machine, Prusa has committed to making these upgrade components available on their webstore by September. These will be sold à la carte, allowing users to selectively purchase the specific improvements that best suit their current printing workflows. A Chronology of Iteration Prusa Research’s development cycle has historically been defined by incremental, data-driven progress rather than rigid annual product launches. The journey to the "plus" lineup has been characterized by consistent feedback loops between the company’s engineering teams and the global community of makers. 2023: The original Prusa XL reaches the market, setting a new benchmark for large-format, multi-material tool-changing performance. Late 2023 (Prusa Day): The company unveils advancements in silicone printing and new high-temperature capabilities, signaling the direction of its future R&D. 2024 (Present): Prusa announces the second-generation "plus" lineup, consolidating years of small firmware tweaks and hardware modifications into a cohesive, standardized production suite. Upcoming (September 2024): The official release of the HT Hotend for the Core One series and the public availability of individual upgrade kits for existing users. This evolution highlights a company that prefers to iterate on proven architectures. While the MK4S, a descendant of the iconic i3 lineage, has been excluded from this particular "plus" wave, the company remains firm in its commitment to supporting legacy hardware, ensuring that the vast majority of its installed base remains functional and relevant. Technical Deep Dive: The Hardware Improvements The "plus" upgrades are not merely cosmetic; they address specific pain points identified by the user community. Chief among these is the integration of a nozzle wiper across all three machines. While users previously relied on community-developed modifications—often requiring complex custom g-code adjustments—Prusa has now standardized this feature, streamlining the multi-material printing process significantly. The XL+ Evolution The XL receives the most substantial overhaul. Drawing inspiration from the MK4S, the XL+ now features a 360-degree cooling system, which drastically improves overhang performance and surface finish. Furthermore, the machine adopts the INDX Tool Offset Sensor. This sophisticated eddy-current sensor is 20 times faster than the previous pin-tapping alignment method and is permanently mounted, removing the need for manual calibration between tool changes. Additionally, the transition to GT1.5 belts ensures better tensioning and higher dimensional accuracy, while the inclusion of high-flow nozzles as standard equipment increases throughput for large-scale prints. Core One+ and Core One L The Core One+ receives the same nozzle wiper and belt upgrades as the XL+, with the added benefit of improved heatbed mounting to ensure long-term thermal stability. It also adopts the snap-on top panel design featured on the larger Core One L, offering a more modular and accessible user experience. The Core One L, being the newest in the lineup, benefits from the integration of the nozzle wiper and the high-precision GT1.5 belt system. Official Stance: The Philosophy of Longevity Mikolau Zuza, Head of Content at Prusa Research, articulated the company’s guiding philosophy in a recent blog post that has resonated deeply with the 3D printing community. "If there’s one thing worth knowing about how we develop our printers, it’s this: we don’t expect you to replace a working machine just because we’ve come up with something new," Zuza wrote. "Most tech becomes obsolete over time. Our printers keep getting better." This sentiment underscores a deliberate rejection of the "disposable tech" culture that dominates much of the consumer electronics sector. By providing upgrade paths rather than forcing machine replacements, Prusa is positioning itself as a partner in the user’s long-term creative journey. This strategy extends beyond hardware; it encompasses the entire software stack. Prusa Slicer 3.0, anticipated in the coming weeks, and the introduction of "Prusa Connect Local" are designed to modernize the user experience, replacing the aging PrusaLink with a faster, more reliable local area network interface. The Implications for the 3D Printing Industry The decision to introduce a high-temperature (HT) hotend for the Core One lineup, capable of reaching 400°C, is perhaps the most significant strategic move for industrial and engineering-focused users. By unlocking materials like PEKK-CF and PPS-CF, Prusa is bridging the gap between desktop convenience and industrial-grade material performance. This move has broader implications for the industry: Standardization of Features: By incorporating "community mods" into the stock build, Prusa effectively raises the baseline expectation for consumer-level 3D printers. Increased Residual Value: Because machines are designed to be upgraded, the resale value of a Prusa printer remains higher than competitors, as the hardware is not rendered obsolete by the next model release. Software-Hardware Synergy: The simultaneous update of firmware, slicer software, and physical components illustrates the importance of a vertically integrated ecosystem. Looking Ahead As we look toward the remainder of 2024, the landscape of the 3D printing market is shifting toward greater reliability and ease of use. Prusa’s "plus" update cycle serves as a case study in customer retention through innovation. By focusing on the "entire experience"—from the moment a file is sliced to the final removal of a part—Prusa is betting that the most successful brand in the space will be the one that respects the investment of its users. For the enthusiast community, the upcoming September release of the à la carte upgrade kits is a milestone. It provides a clear path forward for those who have invested in the current generation of machines, ensuring that they can enjoy the latest technical advancements without the financial burden of purchasing an entirely new unit. As the company continues to refine its printers, one thing remains clear: the goal at Prusa Research is not to sell the most machines, but to ensure that the machines already in service are the best tools they can possibly be.
