At Reinforce 3D, innovation is not only found in our process, but also in the materials that give strength and purpose to each component. Our patented Continuous Fiber Injection Process (CFIP) is built upon one essential element: our proprietary fiber, specifically engineered to deliver outstanding mechanical performance, lightweight efficiency, and structural optimization.
In this post, we explore what makes our fiber different, how they improve performance, and where they are making an impact across industries that demand precision, strength, and advanced functionality.
The difference in a tiny environment with Reinforce3D fiber
Our patented fibers are based on continuous carbon fiber, designed to be injected into internal channels of printed parts via our CFIP technology. Unlike traditional laminate or layer-based methods, CFIP enables targeted reinforcement, injecting fibers directly into the structure where they are needed most. Key performance characteristics include:
- High specific strength (strength-to-weight ratio)
- High elastic modulus – ideal for stiffness-critical parts
- Thermal resistance – performance maintained in high-temperature environments
- Material compatibility – adaptable to a range of high-performance thermoplastics (PA, PPS, PEEK…)
These fibers enable precision reinforcement, maximizing structural performance without unnecessary material usage or added mass.
The principal key benefits of our fiber
- Lightweight strength: Ideal for reducing part weight while increasing or maintaining mechanical integrity—critical in transportation, aerospace, and performance equipment.
- Optimized structural design: Targeted fiber injection reinforces only critical stress zones, improving mechanical behavior and design efficiency.
- Sustainable manufacturing: Less waste, optimized material usage, and lower energy requirements thanks to fiber placement only where it’s truly needed.
- 3D printing compatibility: Perfectly aligned with additive manufacturing technologies, enabling seamless integration into modern production workflows.
Our fiber solutions are actively being implemented across sectors that require robust, lightweight, and high-performance parts:
-In automotive, they’re used for structural brackets, housing, and chassis elements—reducing vehicle weight without compromising safety.
-In aerospace, they reinforce components exposed to cyclic loads and vibration—ideal for drones, satellite structures, and lightweight supports.
-In industrial automation and robotics, CFIP-enhanced parts extend tool life and withstand high mechanical and thermal stresses.
-In sports and mobility, applications like bicycle handlebars or frames benefit from exceptional stiffness and weight savings.
These sectors share one common need: parts that are light, strong, and smartly reinforced—exactly what CFIP delivers.
Our proprietary fibers are designed, tested, and protected under patents to work in harmony with the CFIP process. They are not just carbon fibers—they are part of a fully integrated reinforcement system that brings engineering-grade performance to additive manufacturing.
CFIP fibers are unlocking a new era of material performance—purpose-built for a future where strength meets precision.
