Having as many as 21 flight-critical parts created with 3D printing signals a significant shift in the industry’s confidence in AM for end-use aerospace applications. But what specific advantages compelled Boom Supersonic to opt for AM for such a substantial number of plane parts?

Unlocking Complex Geometries and Superior Aerodynamics

Supersonic flight demands unparalleled aerodynamic efficiency. Even minute imperfections or suboptimal designs can drastically impact performance and fuel consumption. 3D printing empowers engineers to design parts with intricate internal structures and complex external contours that are impossible or prohibitively expensive to produce with traditional subtractive manufacturing. This design freedom allows for optimized airflow, reduced drag, and enhanced overall aerodynamic performance, which are critical for achieving and maintaining supersonic speeds efficiently. For components exposed to the intense forces and temperatures of supersonic flight, the ability to fine-tune every curve and channel is invaluable.

The Imperative of Lightweighting for Supersonic Performance

Weight is the enemy of supersonic flight. Every kilogram saved translates directly into increased speed, extended range, and improved fuel efficiency. 3D printing excels at producing lightweight structures through lattice designs, topology optimization, and part consolidation. Instead of assembling multiple components, a single, complex 3D printed part can perform the functions of several, eliminating fasteners, reducing assembly time, and significantly cutting down on overall weight. This is particularly vital for an aircraft like the XB-1, where every gram contributes to the ability to break the sound barrier and sustain high velocities with reduced operational costs.

Material Innovation: High-Performance Alloys for Extreme Conditions

Supersonic aircraft operate in extremely challenging environments, facing intense heat, pressure, and structural loads. The choice of material is therefore critical. Titanium, known for its high strength-to-weight ratio, excellent corrosion resistance, and ability to withstand high temperatures, is an ideal material for many aerospace applications, especially for supersonic flight. VELO3D’s Sapphire system is specifically engineered to process such demanding alloys with precision and consistency. This capability ensures that the 3D printed components not only meet the required geometric specifications but also possess the superior durability and high-temperature resistance necessary for mission-critical applications in the toughest operating conditions. The robust mechanical properties of VELO3D’s printed titanium parts provide the reliability and safety margins required for an experimental supersonic jet.

The partnership between Boom Supersonic and VELO3D is a testament to the latter’s advanced capabilities. Benny Buller, the Founder and CEO of VELO3D, articulately summarized the unique challenges and solutions: “Aviation hardware is especially difficult to manufacture with 3D metal printing, due to challenging aerodynamic designs that must be balanced with superior durability and high-temperature requirements. VELO3D’s technology allows the production of lightweight, complex designs for mission-critical applications in the toughest operating conditions. Our partnership with Boom is truly an advancement for the metal AM industry, and XB-1 supersonic aircraft is a game-changer for the aviation industry.” This statement encapsulates the core value proposition of VELO3D’s technology: enabling designs that were previously considered impossible to manufacture, with the stringent quality and performance demanded by aerospace.

The Sapphire system differentiates itself with its unique “support-free” printing capabilities for angles down to zero degrees, particularly for internal geometries. This means that complex internal channels, intricate lattice structures, and delicate overhangs can be printed without the need for extensive support structures that are difficult to remove in conventional powder bed fusion processes. For aerospace components, this translates to cleaner parts, reduced post-processing, and the ability to design parts with optimal internal fluid flow paths, which is crucial for cooling systems and engine performance. The high fidelity and repeatability of the Sapphire system ensure that each of the 21 titanium components meets the exacting standards for flight safety and performance.
