3D Printing in the Aerospace Industry

Introduction

Since the 1980s, 3D printing has been pushing limits in the industrial scene. Additive manufacturing, also known as 3D printing, is a layering process that utilizes machine-learning technology to build materials and create 3D objects. Engineers use printing materials like carbon fibre, graphite, metal, plastic and resins to create visual and functional prototypes. There are several ways of digitally manufacturing products, including Stereolithography (SLA), Selective Laser Sintering (SLS), Fused Deposition Modeling (FDM) and Electron Beam Melting (EBM)

3D printing aerospace modules promotes rapid prototype conceptualization and testing for machine components, resulting in higher operational efficiency and productivity. The process also enables the production of lightweight components in various shapes and quantities without generating excessive material waste.

Additive manufacturing is an evolving ecosystem that has spread rampantly across industries. So far, digital productions through 3D printing account for a small percentage of global manufacturing. However, experts expect the numbers to change over time as technology advances!

In this article, we will discuss the use of additive manufacturing in the aerospace industry.

Additive Manufacturing in Aerospace and Defence

Companies are adopting machine-learning technology to 3D print aircraft modules and spare parts like cockpit dashboards, engines and fuel tanks. Some real-life examples of such firms include Airbus, Boeing, NASA and Rolls-Royce.

In aerospace operations, speed and stealth are equally important. However, the manual production of highly-complex aircraft components can be cost-intensive, and that’s where 3D printing comes in.

Additive manufacturing allows aeronautical specialists to create concepts and iterate prototypes faster than traditional processes. It also lets aircraft designers produce lightweight parts to improve a vessel’s aerodynamic efficiency through weight reduction. Military fighter jets require such lightweight qualities, especially during combat. Light vessels allow pilots to achieve a higher surprise advantage over their opponents because they emit smaller visual and radar signatures.

With 3D printing, aerospace and defence companies can significantly enhance their tactical advantage. It is an ideal solution for creating and testing proof-of-concept ideas with complex geometries to reduce the risk of product failure. Scientists use the system to perform in-depth functionality tests for aircraft parts and components. It helps to ensure products meet precise standards for flammability, performance, strength and temperature.

Safety in aerospace is also paramount. In light of this, designers often use 3D printing to manipulate and increase an aircraft’s impact and tensile strength. The thickness of shell parts can greatly influence how optimally an aircraft performs. Additive manufacturing assists aeronautical designers in carefully crafting machine components from materials with high-yield strength, such as titanium. It is a low-density metal with a high strength-to-weight ratio and outstanding corrosion resistance.

Evidently, aerospace engineers have taken advantage of rapid prototyping to drive innovation and boost growth in the industry.

Is 3D printing worth it in Aerospace and Defence?

Yes, it is. From a manufacturing perspective, 3D printing helps companies boost their competitive edge in the market. The digital production of goods offers tremendous supply chain freedom in material sourcing, distribution and customer service. To date, it eliminates manual errors, improves product reliability, reduces operating costs and supports on-demand manufacturing.

Here are three advantages of additive technologies in the aerospace industry.

Freedom of design and complexity

Engineers are constantly looking for ways to optimize the composition and structure of aeronautical machines. Thanks to AI-enabled additive technologies, they can enjoy great flexibility in the proof-of-concept and assembly stages of product development. It provides an avenue where technicians can achieve fast prototype design and iteration, reducing expensive trial and error.

Design freedom also empowers manufacturers to produce light 3D machine parts to manoeuvre aerodynamic efficiency. Engineering teams can use additive manufacturing to merge multiple parts into one to accomplish weight reduction without compromising functionality. The lightweight modules enable machines to emit less carbon dioxide by reducing drag. Additionally, they facilitate longer flight durations and offer higher fuel economy.

Low-volume production

The aerospace industry is an ever-changing market driven largely by innovation. Consequently, aeronautical experts may find it expensive to manufacture large quantities of end-user products. 3D printing provides an ideal solution to navigate such challenges.

Additive manufacturing allows companies to produce machine components and spare parts in small batches using minimal resources. The process optimizes material efficiency and generates lower waste compared to traditional manufacturing. Low-volume manufacturing also enables entities to hasten turnarounds and reduce production lead times. Additionally, it promotes operational sustainability and refines time-to-market strategies.

Seamless on-demand manufacturing

Another advantage of 3D printing technology is its capacity to facilitate on-demand manufacturing. The system minimizes the need for a firm to stock up on inventory as it allows them to print products on order. By doing that, manufacturers can flexibly accommodate customer requests and readily take products to market. Rapid prototyping also enables engineers to scale customization regardless of complexities in the specifications.

Additionally, digital manufacturing eliminates the need for companies to invest heavily in physical warehousing. 3D printing lets engineers scan and store product concepts in computer-based repositories, allowing them to print new parts on-demand basis. The concept streamlines inventory management and enables manufacturers to optimize supply chain networks.

Obstacles in 3D Printing

Technologies like 3D printing make it possible for professionals in numerous industry sectors to achieve remarkable operational milestones. However, they also have their drawbacks.

The following are the familiar obstacles additive manufacturing establishments face:

  1. It is an expensive affair. The cost of acquiring 3D printing equipment can discourage companies with limited budgetary freedom from adopting the technology.

  2. Scientists are yet to achieve mass production breakthroughs through additive manufacturing. Mass-producing 3D units can be difficult mainly because of quality control or quality assurance uncertainties.

  3. Post-processing finishing of products can be tedious if. Most 3D-printed products require cleaning, surface polishing, annealing and painting before going to market. It is an important process that improves product aesthetics and overall quality.

However, all these obstacle can be discussed and faced by partnering a 3D printing service such as Sculpteo, and not handling all the 3D printing work by yourself.

Other Industrial Applications of 3D Printing

Globally, organizations have embraced additive manufacturing, including players in the consumer products industry, the healthcare industry, the automobile industry, and even the education sector. 3D printing allows companies to actualize the digital construction of products by integrating software tools and material science. The process enables the creation of innovative proof-of-concept objects using AI-powered techniques. It also eliminates manual workflows that make it difficult to produce high-end, low-demand products.

Furthermore, additive manufacturing simplifies production, and businesses can use it to accomplish long-term growth and sustainability. It can revolutionize the flow of goods and widen the scope of product markets, impacting international supply chains.
