When comparing 3D printers, it’s easy to get drawn in by the headline figures, and build volume and print speed are often the first to catch the eye. However, an important question to consider is: does it keep working while everyone else has gone home? For FELIX Printers, the answer is yes. At Formnext 2026, the Dutch manufacturer will show machines that are meant to print large parts around the clock, bring down the cost of parts, and keep downtime to a minimum, alongside a custom system that doses personalized medicines with pharmaceutical precision.
Non-Stop Production of Large Parts: the Pro XXL
The Pro XXL is built for production that doesn’t stop when the shift ends. Its integrated drying cabinet holds six filament spools of up to 4.5 kg each. When one runs empty, the machine switches automatically to the next, so long jobs keep running through the night with no one standing by. From early 2027, cost per part will fall further as pellet extrusion arrives through an IDEX configuration. Pellets cost less than filament and can be processed faster, making large-format printing an easier case to make on the balance sheet.
The Pro XXL is built for 24/7 production.
FELIX has also cut the time lost between jobs. Its in-house Quickswap module lets operators change printheads in moments. When a big print is done, the bed rolls straight out of the machine, so heavy parts come off without a struggle. Hardware and control software were developed hand in hand, which keeps operation intuitive and dependable. On the safety side, lockable doors and recirculating air filtration come standard, and the printer can be connected to a central extraction system.
This large-format FDM printer offers a build volume of 1,500 × 1,050 × 1,100 mm (L × W × H), combining generous capacity with speed, precision and ease of use. Thanks to its robust design, the Pro XXL combines a large build volume with the reliability and efficiency demanded by industrial production environments.
In collaboration with Tesseract, FELIX printers developed linear servo motors to achieve acceleration of up to 5,000 mm/s² and high print speeds of up to 500 mm/s. The system also enables precise positioning and helps minimize maintenance-related downtime.
The Same Productivity in a Compact Format: the Upgraded Pro XL
Not every application calls for a printer the size of the XXL. For those that don’t, the upgraded Pro XL brings the same production-first thinking to a 400 × 600 × 600 mm build volume. It’s equally ready for 24/7 operation, with an integrated drying cabinet for four 4.5 kg spools and automatic switching. It also has Quickswap printhead changes, lockable doors, air filtration and an extraction connection, all run from a modernized user interface. Under the hood, a 48 V CoreXY motion system, full CAN bus architecture and Klipper firmware deliver accelerations of up to 1 g and speeds of up to 500 mm/s.
The Pro XL 4.0 is set to print multicolor parts and push cost per print down even further, thanks to multiple printheads and support for both filament and pellets. Depending on customer demand, FELIX is also exploring linear servo motors and an IDEX configuration to raise precision and speed and cut downtime further still.
The Pro XL 4.0 is similar to the Pro XXL, but with a smaller build volume.
Consistent Quality with Engineering Materials: the Drycabinet
Automatic spool switching keeps both machines fed around the clock, but the material going in matters just as much. Moisture is one of the most common causes of inconsistent prints, especially with demanding engineering filaments. That’s the problem the FELIX Drycabinet is designed to solve. It dries filament at up to 90°C and keeps relative humidity below 10%, so every spool is ready to print when it’s needed. The cabinet holds four 4.5 kg spools and can be built into the Pro XL or used as a standalone unit, adding consistent, repeatable results to round-the-clock output.

Precisely Dosed Personalized Medicine
The third highlight on the booth takes FELIX beyond the factory floor: a custom 3D printer that produces personalized medicines. Its standout feature is dosing accuracy, which is essential when the amount of active ingredient in each dose has to be tightly controlled. The machine has an unexpected origin in technology FELIX first developed for food printing. The company adapted it to meet pharmaceutical requirements, an example of how an existing innovation can open the door to a new market.
Built Around the Application
What ties these machines together is the way FELIX works. Its team is small and dedicated, but it covers a remarkably wide range of technologies, from industrial FDM to specialized systems for food, pharmaceuticals and defense. The company is particularly known for developing custom printers fast and building them as one-offs or in series. Every project starts with close collaboration with the customer. Everything from first concept to finished machine is handled in-house, and many FELIX printers go on to become the core of complete solutions that customers sell under their own brands. FELIX has a name for this approach, “Targeted Production Power”: the right technology and performance for each specific application.
