What's New in Gen 2 Overview Assembled vs Kit What You'll Make Running Costs Features Kit Tech Specs What's New in the CORE One+ (Gen 2) Already familiar with the CORE One+? Generation 2 keeps everything that made it a bestseller and sharpens the three things you notice most in day-to-day printing: how long you wait before the nozzle moves, how the finished surface looks, and how clean the very first layer comes out. Less waiting Faster print starts The redesigned heatbed mounting removes the separate "Absorbing heat" wait for materials using bed temperatures up to 85 °C — that covers PLA, PETG and most everyday printing. Higher-temperature materials benefit from a shorter wait as well. Better finish Smoother-looking surfaces New GT1.5 belts make unwanted repeating patterns finer and harder to notice, especially on large, smooth surfaces where even subtle artifacts can stand out. Cleaner first layer Cleaner print starts The integrated nozzle wiper cleans filament from the nozzle before printing, helping keep loose strands and small blobs away from the print surface. Everything the "+" already brought, still included Automatic Top Vent Operation: the printer opens the vent for low-temperature materials (PLA, PETG) and closes it for high-temp materials — true set-and-forget. Easy Flex Loading: a redesigned filament insertion point makes feeding flexible filaments like TPU quick and simple. New Bayonet-Style Spoolholder: accommodates various spool sizes and is ready for a direct-feed drybox setup. All Firmware Updates: every software improvement developed across the entire CORE One lifespan — better print profiles, smoother motion, improved sensors — shipping from day one.

Lead time: Late September. Built in the USA. Accessories to consider The CORE One+ works perfectly out of the box. Still, you may want to consider these accessories to level up your 3D printing game. 1080p Camera with Night Vision Install an optional 1080p camera for remote print monitoring. Connects with a USB-C cable directly into the motherboard and requires an active Wi-Fi connection. Advanced Filtration System Useful when printing ASA and other materials that produce an increased number of ultra-fine particles and fumes. Additional nozzles & sheets Consider a hardened nozzle for abrasive engineering materials, or smaller nozzles for highly detailed models. Features & Architecture Fully Enclosed CoreXY Architecture The advanced CoreXY motion system moves the lightweight printing head instead of the heavy base, allowing for much higher speeds without losing quality. Input Shaper firmware compensates for vibration at high speeds, with travel speeds reaching 600 mm/s. In Gen 2, new GT1.5 belts refine the motion further — repeating surface patterns become finer and far harder to spot. Active Chamber with Smart Ventilation The printer's enclosed chamber heats up to 55 °C. The system monitors temperatures at all times and adjusts automatically to create the best environment for any material you choose. Optional HEPA filtration integrates directly into the enclosure for offices and schools. Nextruder: Precision at Every Layer The Nextruder is our next-gen print head featuring a precise load cell sensor that measures force at the nozzle tip — the nozzle itself becomes the probe. Because it is physical, it cannot be confused like optical sensors. Plus, 360-degree cooling means steep overhangs print cleanly without supports, and nozzles (0.25 mm to 0.8 mm) swap in seconds without tools. Gen 2 adds an integrated nozzle wiper that cleans the tip before the print begins. Robust Steel Exoskeleton All-steel exoskeleton — the enclosure is structural, not an accessory. Exceptional rigidity at high speeds. Nothing is glued. Everything comes apart with a screwdriver. Designed for modders and tinkerers, with replacement parts stocked for years. Compact Footprint, Large Volume 50% less desk space than an MK4S inside an enclosure, yet 30% more print volume (250 × 220 × 270 mm). That efficiency matters whether you're fitting one printer on a desk or 600 into a print farm — which is exactly what Prusa Research does at its own facility. Open-Source Hardware & Firmware CAD files are published. Firmware source code is on GitHub. You can inspect, modify, or compile your own version. No locked bootloaders, no cloud dependency. We've been shipping open-source printers since 2012. The key to successful prints Active Chamber Temperature Control Engineering materials warp when they cool unevenly — corners lift, layers separate, prints fail. The CORE One+ prevents this with a compact chamber that hits up to 55 °C, creating a stable environment. And the best part? While other printers need you to open the door for low-temp materials like PLA, you can keep the CORE One+ closed thanks to smart chamber ventilation.

It is now a team of over 1,000 people, with a factory in Delaware, USA that builds the CORE One+ (Gen 2) units sold in our e-shop and on Amazon. But it started as a one-man project. In 2010, Josef Průša designed an open-source printer that hobbyists could actually afford. It caught on. Years later, the company is still independently owned and still making printers the same way — designed in-house, built to last, and shared openly with the community that helped build them.
