3d printing in aviation

The demand for maintenance, repair, and overhaul (MRO) services is expected to surge in the coming years as airline operators expand their fleet to meet the growing demand for aviation.


As airlines expand their fleets, Maintenance, Repair, and Overhaul (MRO) organizations are striving to adjust their capacity to meet the soaring demand for maintenance services. Adopting additive manufacturing, or 3D printing, presents a substantial opportunity for these organizations.

The recent advancements in 3D printing technology, innovative materials in both plastics and metals, and proactive initiatives by aircraft and engine manufacturers, MROs, and regulatory authorities are significantly boosting the adoption of 3D-printed parts in the aviation industry. Design flexibility enabled by generative AI, on-demand manufacturing through digital inventories, a focus on sustainability, and AI-ML-controlled printing are revolutionizing modern manufacturing.

Aircraft manufacturers are increasingly incorporating 3D-printed parts in the cabin interiors of new-generation aircraft and other components. MRO firms can leverage this trend by integrating polymer 3D printing for cabin modifications. Additionally, additive manufacturing can be applied to conventional MRO tooling for various aircraft maintenance processes.

The benefits of additive manufacturing for MRO businesses are numerous, including faster turnaround times, on-demand production, and enhanced design flexibility. This technology also addresses many common challenges faced in MRO operations.

Additive manufacturing significantly reduces the weight of parts compared to conventional manufacturing methods, leading to lower fuel consumption and CO2 emissions. This approach also minimizes waste, increases material recycling, and streamlines supply chain logistics through on-demand production, helping airlines achieve their sustainability goals. AI and machine learning-assisted 3D printing further optimize process parameters and material selection, minimizing resource waste.


Utilizing biodegradable materials instead of traditional printing polymers can also decrease the CO2 footprint. Additionally, the flexibility in design and manufacturing, consolidation of 3D-printed parts, and the concept of digital inventory all contribute to a more sustainable future.


Using 3D Printing to solve logistical issues related to the supply chain in Localized, In-House Production

3D printing is revolutionizing the shift towards digital inventory by enabling the direct production of parts from digital design files, eliminating the need for traditional tooling like molds. This results in a completely digitized workflow, where software is used for both designing and managing the production of parts.


This technology encourages manufacturers to rethink their production and storage methods. Instead of physical parts occupying warehouse space, digital files can be stored in the cloud or on local disks and accessed whenever needed.


For Maintenance, Repair, and Operations (MRO) businesses, digital inventory is particularly beneficial. They can maintain approved CAD drawings in their repository and use 3D printing to produce parts locally, on demand. This approach reduces the need for physical inventory and is especially effective for aircraft cabin and interior parts that frequently suffer from damage and wear.


The Intersection of Generative AI, AI-ML, and 3D Printing in Digital Manufacturing Scale

MRO firms can enhance their 3D modeling processes by leveraging generative AI for creating detailed models of parts, including those with complex shapes. By providing specific process and performance parameters, AI-driven 3D printing can significantly reduce the time needed to build these models. One example is OpenAI’s Point-E, which converts text prompts directly into 3D point clouds, helping to design intricate shapes for 3D modeling. This method produces 3D images of parts that maintain structural integrity and durability while being considerably lighter.


AI-ML algorithms further improve the process by detecting defects in real time during printing. These algorithms continuously monitor the quality of parts, identifying issues such as metal porosity and raising alerts promptly. This proactive approach minimizes the need for destructive or non-destructive testing, reduces the risk of defects, and cuts down on material waste. Additionally, AI-ML streamlines the qualification process for 3D printing materials, eliminating the traditional trial-and-error method in the R&D stage.


3D Printing Setting up Key Performance Indicators (KPIs) For Maintenance, Repair, and Overhaul

Maintenance, Repair, and Overhaul (MRO) organizations must obtain Part-(one forty five) approval from the Federal Aviation Administration (FAA) or the European Aviation Safety Agency (EASA). This certification is essential for a repair station to legally perform maintenance on aircraft and their components. Additionally, MROs often pursue AS9100 and AS9110 aerospace standards, which outline quality management system (QMS) requirements established by the International Aerospace Quality Group (IAQG) and SAE International.


To design and develop parts, MROs need FAA/EASA , Subpart J, Design Organization Approval (DOA). For manufacturing parts, they require FAA/EASA Part, Subpart G, Production Organization Approval (POA).


With these approvals, MROs can use Original Equipment Manufacturer (OEM) design data to produce parts, accessing digital inventories to retrieve necessary drawings and specifications. If OEM design data is unavailable, MROs can create Parts Manufacturer Approval (PMA) parts by utilizing their own POA and DOA to design and develop the required drawings.
