Additive manufacturing, commonly known as 3D printing, has revolutionized multiple sectors, and aeronautics is no exception. At Indaero, we apply this technology to create three-dimensional parts by adding material in layers, facilitating the production of lightweight, complex and highly customizable components, critical elements in the optimization of aircraft efficiency and safety. We specialize in meeting the needs of companies seeking innovative solutions in the aeronautical engineering sector, guaranteeing precision and quality in each manufactured part.
What is additive manufacturing?
Additive manufacturing is a process in which, from a digital design, a part is built by adding successive layers of material. Unlike traditional subtractive manufacturing, where material is removed from a solid block, additive manufacturing allows building layer by layer, opening the door to greater design flexibility and customization. At Indaero, we have the technology and experience to carry out these processes efficiently, and we can collaborate with any company that requires custom-designed, high-quality parts for their aeronautical projects.
Advantages of additive manufacturing in the aeronautics industry
Additive manufacturing has several key benefits in the aerospace industry:
- Weight reduction: 3D printed parts can be up to 60% lighter than their traditionally manufactured counterparts, improving fuel consumption and, consequently, aircraft energy efficiency.
- Design flexibility: Complex geometries that were previously impossible can be created, allowing for more optimized designs adapted to aeronautical needs.
- Reduced material waste: Since only the necessary material is used, waste is minimized, helping to reduce costs and environmental impact.
- Production time: By reducing the need for molds and tooling, manufacturing times are significantly shortened, speeding up the production of prototypes and components.
Main additive manufacturing processes in industry
Selective laser sintering (SLS)
The selective laser sintering process uses a laser to melt metal or polymer powder to build high-strength, precision parts. It is ideal for the creation of lightweight and durable components, essential in aeronautics.
Fused Deposition Modeling (FDM)
Fused deposition modeling consists of the extrusion of thermoplastic material filaments, building the part layer by layer. Its popularity is due to its accessibility and versatility, especially in design prototyping and functional testing.
Stereolithography (SLA)
Stereolithography uses a UV laser to solidify liquid resins. This process is capable of producing high precision parts and complex geometries, useful in rapid prototyping and the creation of detailed parts for the industry.

Materials used in additive manufacturing for aeronautics
The materials used in additive manufacturing must meet strict requirements for durability and light weight. The most common in the industry are:
- Aluminum: Lightweight and corrosion resistant, ideal for components exposed to extreme environmental conditions.
- Titanium: Its strength and low weight make it suitable for critical structural parts.
- High-strength polymers: Materials such as nylon and ABS are used in prototypes and interior components, thanks to their low weight and good mechanical strength.
Applications in the aeronautical industry
Additive manufacturing has found key applications in aeronautics, bringing innovation and optimization in the production of:
Light structural parts
3D printing enables the creation of lighter structural components, such as supports and frames, improving the weight-to-strength ratio of aircraft and optimizing their overall performance.
Turbines and propulsion systems

Rapid prototyping is vital in aeronautical design. Additive manufacturing allows the creation of high precision prototypes and parts adapted to specific needs, reducing development time and cost. At Indaero we can help you with any type of part you need, we are specialists in the manufacture of aeronautical parts.
Challenges and regulations of additive manufacturing in aeronautics
Initial costs
Despite the benefits, the implementation of additive manufacturing in aeronautics requires considerable upfront investment in advanced equipment and materials. However, the material and time savings in the long run outweigh these costs for many companies.
Quality and safety certifications
In the aeronautical sector, additive manufacturing must comply with strict regulations and quality certifications, such as those established by the FAA (Federal Aviation Administration) and EASA (European Aviation Safety Agency). These regulations ensure that the parts produced meet the necessary safety requirements for their application in aircraft.
The future of additive manufacturing in aeronautics
The future of additive manufacturing in the aerospace industry is promising, with developments in advanced materials and automated processes that will further improve the production of critical parts. The integration of technologies such as the Internet of Things (IoT) and artificial intelligence will facilitate the creation of more efficient and customized manufacturing processes.
The trend towards more sustainable and environmentally friendly manufacturing is also driving research into recyclable and biodegradable materials. Additive manufacturing, by reducing waste and enabling on-demand production, is positioned as a key technology in the transformation of the aerospace industry towards a more efficient and environmentally friendly production model.
