Prusa CORE One L+ precision review
The $25 Upgrade That Made 3D Printing Seriously Smooth
In the world of 3D printing, perfection often lies in the details. While many manufacturers focus on pushing thermal limits, Prusa Research has demonstrated that a small, intelligent upgrade can transform a capable machine into a truly exceptional tool. This is the story of how a modest refinement turned the CORE One L into the CORE One L+, elevating a popular open-source printer line and proving that even the most practical machines can be made dramatically better.
For years, serious users have wrestled with a persistent annoyance: nozzle wiping failures. When printing high-temperature filaments, the tendency for oozing and missed clean-ups often led to frustrating downtime. While the occasional failure wasn’t a catastrophe, the lost time waiting for manual intervention was certainly irritating. The fix wasn’t a massive redesign; it was a targeted solution, born from years of practical workshop experience.
Prusa Research addressed this common pain point by introducing the CORE One L+ upgrade. This wasn’t just a cosmetic tweak; it involved integrating critical mechanical components that dramatically improved the reliability and smoothness of the printing process. The addition of silicone nozzle wipers, coupled with the implementation of GT1.5 timing belts, immediately solved the wiping issues, allowing users to set their machines and forget them.
The impact of this change extended far beyond just avoiding print errors. The improved system resulted in smoother surfaces and greater precision,
