The 2.20 Revolution: Recreus Redefines Flexible 3D Printing Standards
The 2.20 Revolution: Why We Created a New Standard for Flexible 3D Printing
Today marks a historic milestone at Recreus. Thirteen years ago, we were pioneers with the launch of Filaflex, changing the perception of what a 3D printer could achieve. Today, we are breaking the rules once again with the official launch of the Filaflex 2.20 System. After years of listening to your challenges, we have developed the ultimate solution to the most persistent problem in elastic materials.
The Challenge: Ending the "Hot Spaghetti" Effect
Anyone who prints with high-elasticity materials, such as our Filaflex 60A, knows the struggle: trying to push an extremely soft 1.75 mm filament is like pushing cooked spaghetti. This lack of structural rigidity often leads to jams and forces users to print at frustratingly slow speeds.
Two years ago, our CEO Ignacio García asked: "What if the 1.75 mm diameter simply isn't right for flexibles?" After months of prototyping, we found the sweet spot: 2.20 mm.
Why the 2.20 System Changes the Game
This is not just a new diameter; it is a leap in industrial reliability and performance:
- Goodbye to Jams: Its structure is almost three times more resistant to buckling. It’s like replacing a fragile thread with a robust beam.
- 3x Faster Speeds: The mechanical stability allows for revolutionary printing speeds without risking extrusion failure.
- Double Productivity: For print farms, doubling production of flexible parts used to mean buying more machines. Now, you can double your capacity just by upgrading the hotend.
Why 2.20 mm and not 2.85 mm? The Engineering "Sweet Spot"
A logical question would be: "If the problem is a lack of rigidity, why not just use the 2.85 mm standard?". The answer lies in polymer physics and heat transfer:
- The 2.85 mm Problem: Due to its high thermal mass, the filament takes significantly longer to melt homogeneously at the core. This drastically limits the maximum flow rate and creates underextrusion issues when trying to print fast.
- The 2.20 mm Advantage: We have found the "sweet spot." It is thick enough to provide 58% more cross-sectional area than 1.75 mm (preventing buckling), yet balanced enough to melt with the same thermal efficiency as thinner filaments.
In short: 2.20 mm combines the mechanical strength of large diameters with the melting speed of small diameters. It is, quite simply, the perfect geometry for elastomers.
Ready to Upgrade? Discover our Launch Bundles
To make the transition seamless, we have designed specific Launch Bundles that include everything you need to start printing at high speed: the new custom Hotend and the first spool of Filaflex 2.20.
The system is currently available for:
(More models and compatibility coming very soon!)
The Flexible Future Is Here
The 1.75 mm standard was born for rigid materials. The Filaflex 2.20 System was born to unlock the true potential of flexibility. It is time to stop babysitting your printers and start scaling your production.
