This summer, we are refreshing the entire lineup of our 3D printers. The new Prusa XL+, CORE One+ (Gen 2), and CORE One L+ bring cleaner print starts, better-looking surfaces, easier operation, and improvements based on feedback from users and the community.

Prusa printers keep getting better over time!

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. Most tech becomes obsolete over time. Our printers keep getting better. 🙂

A huge part of it happens through updates. Firmware brings new features, print profiles get fine-tuned, PrusaSlicer keeps evolving – and your printer gets all of it and learns new tricks, no matter whether it arrived last month or years ago. Our ecosystem keeps moving forward, and it takes your machine along with it. And when it takes new hardware? It’s upgrade time! Get your screwdriver out and give your trusty machine a brand-new set of abilities at an affordable price. An older open-frame printer can get new electronics, then a new extruder, and eventually even a full conversion into a fully enclosed CORE One+. It’s like when you upgrade your PC with new components.

That’s exactly what’s happening now, too. The 2026 refreshed lineup, the CORE One+ (Gen2), CORE One L+ and XL+, all have available upgrade paths for all current owners.

This is exactly why the same Prusa can sit on a NASA engineer’s desk, end up under a Christmas tree as someone’s first technical project, run daily in a busy university lab, and print parts that go to orbit or into critical infrastructure. They don’t age like most tech, and the entire lineup shares the same platform – technology, software, PrusaSlicer, and long-term support. So everything you learn on one Prusa carries over to any other.

We like to say a Prusa is an investment, and this is a great example of why it works. You buy the hardware once, and whenever there’s an upgrade, you get the option to take it.

Better User Experience, Even Better Prints

So, let’s get to the actual upgrades. With this refresh, we focused on the everyday experience and also found ways to push the print quality even that one bit further.

Of course, not every improvement needs to transform what a printer can do. Often, it’s the little things that remove various annoyances or delays – and this is what the other part of improvements focuses on. We’re talking mainly about faster pre-print preparations, cleaner results, fewer calibrations and tuning. In general, the goal is to spend less time waiting and more time printing and enjoying the finished models.

Throughout the development, we went through a lot of community feedback – to give you a quick example, one of the most frequent requests was a nozzle wiper, which is now available on all three machines. We deliberately chose a standard, widely available nozzle wiper. Since it is a consumable part that will eventually wear out, replacements should be easy to find. You will be able to get one from us, your local 3D printing store, or wherever is most convenient.

Bringing the Prusa XL up to our latest generation

We’re upgrading the XL to XL+, and it’s a pretty substantial improvement. The XL remains the largest, most capable toolchanger on the market with its massive 360×360×360mm build volume – it’s 3× the size of the CORE One+ and 1.5× the CORE One L+. And it still fits on a workbench and plugs into a standard socket. It’s built for huge prints and for projects that combine multiple materials or nozzle sizes. We focused on bringing its print quality and everyday experience on par with our latest generation of printers.

The biggest practical improvement is the new 360-degree cooling system, matching the awesome cooling of the MK4S and CORE One series. The new cooling delivers more airflow overall and distributes it more evenly around the nozzle, improving overhangs, bridges, and small details, particularly on demanding models.

Another major improvement comes directly from the INDX: the new Tool Offset Sensor checks and precisely aligns every toolhead during the initial setup, which is especially important for multi-color prints and layer-based color mixing. The previous automatic calibration used a removable pin and took long minutes. The new permanently mounted eddy-current sensor is about 20 times faster! It is also compatible with the upcoming Silicone toolhead, which is currently scheduled for release this Fall.

The new GT1.5 belts also bring a visible improvement. They help make unwanted fine repeating patterns less noticeable, which is especially useful on the large, smooth surfaces the XL is often used to print.

High-flow nozzles are now included as standard, giving the printer more headroom when a print calls for higher material flow. The integrated nozzle wiper cleans off filament before the print begins, helping prevent loose strands or small blobs from being carried onto the print surface.

The XL+ itself is ready for chamber temperatures up to 60 °C. Our new enclosure is better sealed and can reach around 50 °C using the heat already generated by the printer. Add the upcoming chamber heater, and it can go all the way to 60 °C.

A warmer, more stable environment is a big help with large PC Blend and PCCF parts, and even big, boxy PETG prints, where it helps the part stay closer to the intended shape and dimensions. We don’t have a shipping date for the heater yet, but we wanted to show you what’s coming.

With the new improvements, the XL+ gets even better at the things that make it special: massive print volume, a super-fast toolchanger, and all of it still fits on a workbench and plugs into a standard socket.

What’s new for the CORE One series

The CORE One+ (Gen 2) and CORE One L+ share the same core idea: enclosed printers that offer a lot of printing space without taking over the room. One is the compact all-rounder, while the other gives you more room for large parts and bigger batches.

Because the CORE One L was developed more recently, it already includes several ideas that are now making their way back to the smaller model. The two refreshes are therefore slightly different, but they bring the everyday experience even closer together.

Prusa CORE One L+

The CORE One L is our larger enclosed printer, with a 300 × 300 × 330 mm build volume, an actively controlled chamber, and a large all-aluminum AC heatbed.

With the CORE One L+, we are also adding the new GT1.5 belts and integrated nozzle wiper that is shared across the refreshed lineup.

Prusa CORE One+ (Gen 2)

The CORE One+ (Gen 2) receives the broadest set of changes in the CORE family. It gains the same nozzle wiper and GT1.5 belts as the XL+ and CORE One L+, giving each print a cleaner start and making fine patterns on smooth surfaces harder to notice.

One of the most noticeable improvements is how quickly it now gets to printing the first layer. This comes in handy when you want to check that a print has started properly before leaving the office or heading out for the day.

We redesigned the heatbed mounting so it can warm up and stay flat without the extra wait. For PLA, PETG, and any material printed with a bed temperature of 85 °C or lower, the “Absorbing heat” step is gone. Higher-temperature materials start sooner as well.

The printer also receives the snap-on top panel introduced with the CORE One L. It can be removed in seconds without tools, making cleaning and maintenance easier. The automatic top-vent mechanism underneath is also more robust.

Individually, these are relatively small changes. Together, they mean faster starts, smoother surfaces, easier maintenance, and less attention needed every time you print.

Availability, rollout, and upgrades for existing owners

The refreshed lineup is on sale right away: the CORE One L+, CORE One+ (Gen 2), XL+, also including the CORE One+ kit and all XL+ toolhead configurations. Even with the new (and additional) hardware, we’re keeping the same price for all machines.

The first assembled CORE One+ (Gen 2) and CORE One L+ printers start shipping immediately, with assembled XL+ printers following later in August. Kits, upgrades, and individual parts will roll out over the following weeks as we ramp up production and finish the corresponding upgrade manuals.

If you already have an open order for a CORE One+, CORE One L, or XL that has not shipped yet, we will automatically upgrade it to the corresponding new version, regardless of when the order was placed. There is nothing you need to do.

Complete upgrade kits are coming, and the new components will also be available individually in our store. There are quite a few printer and upgrade combinations to cover, so we are starting with assembled machines and CORE One+ upgrades, followed by CORE One L+ and XL+ upgrades around the end of August and beginning of September.

And of course, hardware upgrades are only part of the story. Existing XL, CORE One L, and CORE One printers will continue receiving firmware updates, PrusaSlicer improvements, print profiles, documentation, spare parts, and support.

What’s next?

The changes in this refresh mark the start of a broader push to improve the user experience across everything we make. We are looking at the whole process, from preparing a file and starting a print to managing and maintaining the printer, not just adding headline features.

A lot of this work comes directly from feedback. Many of you know Tommy, our community manager, who has spent a great deal of time talking with users and bringing their comments back to the team.

Stefan from CNC Kitchen also took the time to prepare a detailed summary of his experience and suggestions. We went through it carefully and took it to heart. And then there are companies, universities, public institutions, government organizations, and critical infrastructure operators, all providing valuable feedback based on their everyday experience.

We’ve already implemented many improvements in the previous firmware updates, the refreshed printers are the next visible result.

And we hear you: “Refreshed printers, that’s nice. But what about…?” Well, here you go!

INDX for the CORE One+ is almost here

INDX brings automatic tool changing to the CORE One+, allowing it to switch between different colors, materials, or nozzle sizes during a single print with very little waste.

The first units will begin shipping very soon, and they are, of course, fully compatible with Gen 2.

And if you already have INDX Conversion Kit on order, don’t order the Gen 2 upgrade just yet. 😉 We’ll post a bigger update regarding INDX next week.

We are successfully running tests with INDX on the CORE One L, more updates about it will follow later.

Automatic filament calibration (Pressure Advance) before every print

Even two spools of the same material can behave slightly differently. We test, test, and test again, which is how we provide fine-tuned profiles not only for Prusament, but also for almost every major filament brand. Still, individual spools can vary.

And it turns out that simply tuning one Pressure Advance value is not the whole story either. Filament behaves differently depending on how fast it is flowing, so we are introducing a new model that adjusts for this instead of relying on one fixed value.

Before each print, the load cell will automatically measure the loaded filament and calibrate the two parameters the new model needs. The printer can then adjust extrusion more accurately as the flow changes during the print. We are also adding extrusion-aware acceleration limits, so the printer does not ask the extruder to change flow faster than it physically can.

The nice part is that you won’t have to think about any of this. Load the filament and print. We have been testing the system internally for a while, and we will release it once we are confident it works reliably with every filament we can get our hands on.

PrusaSlicer 3.0

PrusaSlicer 3.0 is the next generation of our open-source slicing software, rebuilt around the way people actually prepare and manage prints today. The first alpha version is coming within weeks, and it will be a major step forward for the software used to prepare every print.

PrusaSlicer is shared across our entire lineup, so this is not an improvement for any one new printer. Current and older machines will benefit from it as well.

The HT Hotend arrives in September

Our upcoming HT Hotend is designed for high-temperature engineering materials. It has taken longer than originally planned because we wanted it to work reliably with third-party filaments, not only under ideal conditions with a small selection of materials.

These filaments can be expensive, and some of them are brittle. If the material breaks in the feeding mechanism halfway through a long print, it does not matter how well the hotend reaches its target temperature.

We redesigned and retested the system with a much wider range of filaments rather than releasing it before it was ready.

The HT Hotend will be available for the CORE One L/+ and the CORE One / One+ / One+ (Gen2) in September.

Prusa Connect Local to replace PrusaLink

Remotely controlling your printer over the local network has always been possible with PrusaLink, but we want to make it so much better. Instead of slowly adding more to PrusaLink, we decided to build its successor from scratch, using what we have learned from Prusa Connect along the way.

Prusa Connect Local brings the modern Connect experience directly to your local network, with no cloud connection required. It is also being built as an open, extensible, multi-protocol system, so the community can add support for other integrations over time.

We are already quite far along and preparing early access now. The first round will be aimed mainly at more technical users comfortable testing and compiling the software themselves.

The whole lineup, upgraded

The XL+, CORE One L+, and CORE One+ (Gen 2) each have slightly different areas where they fit best, but they now share more of the same technology and the same refined experience.

Cleaner starts, better cooling, smoother surfaces, less waiting, and fewer small things that need your attention. Individually, these changes may sound straightforward. Together, they make the printers noticeably easier to use every day. Happy printing!
