Reinforce3D is a start-up created in 2022 aimed to further develop and commercialize the Continuous Fibre Injection Process (CFIP) technology. CFIP is a new post-process technology which drastically improves the mechanical and light-weighting performance of 3D printed parts by reinforcing them with continuous fibres such as carbon fibres.
Interview with Blanca Garro, CEO & Ingrid Algarra, Marketing & Communications Specialist at Reinforce3D.
How do your products or solutions help clients lower their overall operating costs?
Blanca Garro & Ingrid Algarra: Our reinforcement technology can be applied to virtually any material that contains cavities, which gives manufacturers tremendous flexibility. Instead of redesigning a part to withstand higher loads or using more expensive bulk materials, clients can simply reinforce the structure internally where strength is most needed.
This translates into several cost advantages: reduced material consumption, fewer rejected parts, and lighter designs that save energy in use. Because our process integrates reinforcement directly inside the component, it also minimizes the need for complex assemblies, adhesives, or fasteners, further reducing production steps and labor costs. The result is stronger, longer-lasting parts manufactured more efficiently — lowering both production and operational costs across industries from aerospace and automotive to consumer goods and industrial applications.
In what ways do you contribute to improving efficiency or productivity for your clients?
B.G & I.A: We help manufacturers optimize their production by simplifying reinforcement and reducing rework. Because our technology integrates reinforcement directly into parts with cavities, clients can avoid additional assembly steps such as bonding, fastening, or complex redesigns. This leads to shorter production cycles, less manual intervention, and fewer potential points of failure.
At the same time, the ability to strengthen parts precisely where needed reduces the number of rejected or non-conforming components, which directly improves yield. For manufacturers, this translates into more streamlined workflows, better use of resources, and higher overall productivity across their production lines.
How do you help clients reduce energy, material, or resource consumption?
B.G & I.A: Our reinforcement technology allows manufacturers to achieve the required strength and performance using less raw material. Instead of overbuilding parts, we reinforce only where it’s needed, which helps cut waste. In many cases, clients can even start with a cheaper base material and once reinforced, still meet the performance requirements. On top of that, our out-of-autoclave process uses less energy than traditional methods, and fewer rejected parts means less overall waste throughout the production cycle.
What technical characteristics in your solutions reduce maintenance or lifecycle costs?
B.G & I.A: By reinforcing parts from the inside, our technology increases strength, stiffness, and damage tolerance. This means components are less likely to crack, deform, or fail under load, which reduces the need for rework or replacement. Because we can place reinforcement exactly where it’s needed, parts maintain their performance for longer — even when made with less expensive base materials. For manufacturers, this results in fewer defective parts during production and longer-lasting components in service — both of which contribute to lower lifecycle and maintenance costs.
How do you support clients in minimizing downtime or production interruptions?
B.G & I.A: Our reinforcement process is designed to integrate smoothly into existing manufacturing lines. It requires no heavy autoclave equipment and only minimal changes to current workflows, so installation and start-up are fast. Because reinforcement is applied directly inside the part, there are fewer secondary operations and less risk of defects, which reduces unplanned rework or stoppages. The result is a more stable production flow and less downtime for our clients.
In what ways do your solutions simplify processes and reduce further costs?
B.G & I.A: Our technology reinforces parts internally, so manufacturers can avoid secondary operations such as adding fasteners, bonding, or redesigning parts for extra strength. CFIP’s decoupled architecture separates printing and reinforcement into independent stages, which streamlines production and limits disruptions. The DELTA machine’s quick-change fiber cartridges and low-maintenance design further cut setup time and operator effort. Fewer steps, less manual work, and lower rework rates translate directly into shorter production cycles and lower overall manufacturing costs.
How do your technologies enable clients to scale operations in a cost-effective way?
B.G & I.A: Clients can expand production using their existing manufacturing equipment — whether additive manufacturing (AM) or other processes that create internal cavities — while reinforcement is carried out independently on one or more DELTA system. This decoupled setup lets investment in reinforcement grow in line with production needs.
What sets Reinforce3D apart is that CFIP integrates directly into current manufacturing workflows, with no need to redesign factory layouts or install complex composite infrastructure. By upgrading conventional production with high-performance internal reinforcement, CFIP allows clients to scale efficiently while maintaining tight cost control and consistent part quality as volumes increase.
How do you help clients meet regulatory or sustainability requirements without excessive costs?
B.G & I.A: CFIP reinforcement enables manufacturers to reach required mechanical and safety standards without over-engineering parts or switching to expensive premium materials. By reinforcing only where strength is needed, clients use less raw material and can often select lower-cost base materials while still meeting performance specifications. The out-of-autoclave process consumes less energy and produces less waste than traditional composite methods, helping clients align with tightening environmental regulations. Because CFIP integrates into existing production lines, these gains come without major capital investment, allowing manufacturers to satisfy regulatory and sustainability goals while keeping costs under control.
What role does automation or digitalization play in cost savings for your clients?
B.G & I.A: Automation and digitalization are fundamental to CFIP’s value proposition. The reinforcement process is guided by software-generated fiber paths based on the part’s geometry, ensuring precision and repeatability regardless of operator experience. The system controls key parameters — such as pressure, speed, and position — in real time, reducing manual intervention and minimizing variability.
In addition, the process generates digital records for each reinforced part, enabling full traceability and process validation, which are essential for quality control and certification. This level of automation not only lowers the risk of rework and scrap but also reduces labor requirements and simplifies integration into existing digital manufacturing environments.
Can you share a concrete example where your solutions generated measurable budget savings?
B.G & I.A: In a recent project with a UAV VTOL, CFIP was used to reinforce lightweight drone components — including arms and internal structural frames — originally designed in carbon-filled polymers. By integrating continuous fiber reinforcement internally, the client was able to reduce material usage by 35%, achieve a 28% improvement in stiffness-to-weight ratio, and eliminate the need for post-processing or adhesive bonding.
The switch to CFIP-enabled parts also allowed the use of more cost-effective base materials without compromising performance, resulting in a total part cost reduction of over 40%. This case demonstrates how CFIP delivers tangible value in high-performance, weight-sensitive applications — stronger, bigger, lighter… and most times, cheaper!
