The launch of Reciflex significantly broadens Recreus’ product portfolio, driven by a clear strategic objective: to vigorously promote the circular economy within the 3D printing landscape. This initiative represents a substantial stride forward in terms of sustainability, directly responding to and fulfilling the evolving demands of its growing customer base. Ignacio García, the visionary CEO of Recreus, articulates the company’s motivation, stating, “This is a project that was very much on our minds at Recreus, and we were eager to tackle it. The community, customers, and the industry were also demanding it, and thanks to the extensive research and testing work we have conducted in recent months within the company, we have achieved a truly exceptional material as a result.” His words underscore the blend of internal drive and external market necessity that fueled the development of Reciflex, highlighting a collaborative effort toward a greener future in additive manufacturing.

Reciflex: Uncompromising Quality from Recycled Materials

Despite its origin from recycled products, Recreus steadfastly upholds its commitment to producing filaments of uncompromising quality. The manufacturing process for Reciflex filament is a testament to this dedication, involving meticulous selection and a rigorous magnetic screening procedure. This critical step is implemented to effectively prevent any metallic residue from entering the filament, thereby guaranteeing that the material will perform flawlessly and reliably throughout the 3D printing process. Such attention to detail ensures that users experience consistent results, free from potential issues that recycled materials might otherwise present.

Reciflex boasts a hardness range between 96A and 98A SHORE “A”. While minor variations in hardness can occasionally be attributed to its recycled origins, these are engineered to be practically imperceptible in the final 3D printed parts, ensuring that functional integrity is never compromised. This specific hardness range positions Reciflex as an outstanding choice for manufacturing parts that demand robust mechanical requirements, excellent flexibility, and high durability. Typical applications include protective phone cases that absorb impact, robust drone protections designed to withstand harsh landings, resilient wheels for radio control cars and robots that endure constant motion, or any part requiring contact with aggressive solvents. Its properties make it suitable for custom gaskets, flexible tooling, protective gears, and components in footwear or sporting goods, where both elasticity and resistance are paramount. The versatility of Reciflex extends to various industrial and consumer applications where sustainable yet high-performance flexible materials are essential, bridging the gap between ecological responsibility and engineering excellence.

For optimal results when working with Reciflex, Recreus provides specific printing recommendations. The manufacturer advises a printing temperature between 220 and 235ºC, which is ideal for achieving proper layer adhesion and flow consistency characteristic of TPU materials. A printing speed ranging from 20 to 60 mm/s is recommended, balancing detail preservation with efficient production, crucial for flexible filaments. Furthermore, a printing plate temperature set between 50 and 60ºC is suggested to ensure excellent first-layer adhesion and minimize warping, a common challenge with many thermoplastic filaments. Users are encouraged to conduct calibration prints to fine-tune these settings for their specific 3D printer and printing environment, thus maximizing the potential of Reciflex.

Interestingly, Reciflex is currently available exclusively in a solid and bright black color. This deliberate choice is a direct consequence of its recycled nature. When various recycled plastic colors are mixed during the production process, the black pigment is strategically added. This addition serves to homogenize the diverse color palette of the incoming recycled materials, resulting in a consistently vibrant and uniform black finish. Far from being a limitation, this black color symbolizes the fusion of disparate waste streams into a single, high-quality, and environmentally responsible product. The filament reels are offered in two convenient weights: 750g for smaller projects or initial testing, and 3kg for larger-scale production or frequent use. Users also have the flexibility to choose between two standard diameters: 1.75 mm and 2.85 mm, ensuring compatibility with a wide range of FDM 3D printers on the market.

Recreus and the Broader Push for Sustainability in Additive Manufacturing

From its inception, additive manufacturing was heralded as a transformative solution for more sustainable production. Its core principle of building parts layer by layer, rather than cutting away material, inherently generates significantly less waste compared to traditional subtractive manufacturing methods. This promise of efficiency and resource conservation was a key selling point for 3D printing technology. However, as the industry matured and its applications expanded, it became increasingly apparent that there were significant roadblocks to truly deeming it eco-friendly. The pervasive reliance on plastic as one of the most widely used materials in 3D printing has emerged as a primary concern, contributing to the global plastic waste crisis.

In response to this growing challenge, a robust and expanding movement has emerged within the 3D printing community, passionately dedicated to finding viable solutions. Extensive research and development efforts are underway, exploring innovative more sustainable materials. These investigations span various avenues, from bio-based polymers derived from renewable resources to composites incorporating natural fibers, and even the exploration of unconventional materials like mycelium. In this dynamic landscape, Recreus’ Reciflex filament represents a pivotal step in the right direction. By offering a high-performance plastic filament manufactured entirely from recycled materials, Reciflex clearly demonstrates another impactful way that 3D printing can dramatically reduce its environmental footprint, transforming waste into valuable resources and moving closer to a truly circular economy. This not only mitigates plastic pollution but also conserves virgin resources, embodying a more responsible approach to technological advancement.

The team at Recreus is acutely aware of the inherent paradox in being a leading producer of plastic filaments while championing environmental causes. However, this awareness does not deter them; instead, it fuels their unwavering commitment to safeguarding the environment and fostering the principles of a circular economy. Ignacio García reinforces this philosophy, stating, “All companies have to go in this direction, there is no other way! In our production processes, we consistently integrate sustainable actions, such as reusing the water collected by our dehumidification rooms for the filament production process. These gestures, however small they may seem, are actions that collectively contribute significantly in the end. We are deeply conscious of our role in the industry, and our ultimate goal is to provide, in addition to high-quality 3D printing filaments, comprehensive integral solutions that genuinely respect the environment, as exemplified by Reciflex.” This statement highlights Recreus’ holistic approach to sustainability, integrating eco-friendly practices throughout their operations, from raw material sourcing to manufacturing processes.
