China3D printingNet October 9th, the aerospace company Boom Supersonic launched the XB-1 aircraft for the first time, which is characterized by3D printingA large number of additively manufactured parts manufactured by machine manufacturer VELO3D.
Boom’s supersonic jet was launched in the company’s hangar in Centennial, Colorado. It includes 21 types of engine-related engines.3D printingComponents. Benny Buller, CEO and founder of VELO3D, said that the parts produced under the cooperation of the two companies marked the feasibility and feasibility of supersonic travel.3D printingThe “turning point” of the aerospace capabilities of the parts.

Said: “Because the challenging aerodynamic design must be balanced with outstanding durability and high temperature requirements, aviation hardware is particularly difficult to use.Metal3D printing manufacturing. VELO3D’s technology allows the production of lightweight, complex designs for mission-critical applications under the most demanding operating conditions.
Our partnership with BOOM is indeed an advanced technology in the metal additive manufacturing industry, and the XB-1 supersonic aircraft is a revolution in the aviation industry. “
Boom Supersonic’s XB-1 aircraft
Boom Supersonic was established in 2014 with the stated goal of making commercial supersonic air travel a reality again. The company’s XB-1 prototype aircraft is under development as a proof of concept, demonstrating the potential of its 2.2 Mach (1,687 miles per hour) “Overture” passenger aircraft, which is scheduled to be put into service in 2030.
XB-1 is the first self-developed supersonic aircraft, and its custom composite structure includes more than 3,700 parts, including landing gear, flight control actuators and cooling system.In order to solve the arduous task of building its demonstration aircraft, Boom sought out two established brands3D printingMachine manufacturer’s help.
Initially, Boom Supersonic partnered with Stratasys to use the company’s F370 and Fortus 450mc 3D printingThe machine has developed more than 200 tools, prototypes and test bench parts related to XB-1. The two companies reached a long-term agreement that went beyond the scope of prototype applications and saw Stratasys’ F900 system used to produce end-use parts for Boom’s supersonic aircraft.
Soon after reaching a new agreement with Stratasys, Boom also began to cooperate with VELO3D to develop more end-use parts for its passenger aircraft. At the time, VELO3D claimed that its Sapphire system was optimized to produce large-diameter parts without support and would be able to create enhanced aerospace parts with little or no post-processing.
After a series of successful qualification tests using VELO3D machines, the two companies continue to produce various3D printingParts, these parts are now installed in Boom’s XB-1 prototype.

Using VELO3D’s Sapphire system, Boom was able to total3D printingThere are 21 structural, engine and environmental control components, some of which have a wall thickness of only 0.02 inches.As many XB-13D printingThe parts are all related to guiding the air, including blades, air ducts and shutters, so they must be narrow and complex, and at the same time they should have high tensile strength.
The geometric design of aircraft aerodynamic parts includes high and thin walls with high aspect ratios, which are difficult to manufacture with traditional welding and casting processes. At the same time, VELO3D’s proprietary SupportFree printing process can achieve a high degree of design freedom and quality control.
As a result, Boom was able to realize its vision of the aircraft without having to consider design constraints such as support. Gene Miller of VELO3D, who worked closely with Boom’s design engineers, emphasized that it is impossible to achieve XB-1 parts using more conventional production techniques.
“Boom specifically designed all these components for their new aircraft.” Miller explained. “The unique type of geometry they created to guide the flow (focusing on reducing weight) cannot be done by sheet metal or casting or any other means. In order to obtain the benefits of complex design and weight reduction at the same time, the only option is to use metal AM.
Supersonic flight brings many different phenomena, and you don’t usually see this pressure on regular air travel.
According to China3D printingThe network understands that many boom parts are also printed for use in the important engine area of the aircraft, including the manifold of the variable bypass valve (VBV) system, NACA pipes and two splitter flange parts. NACA ducts are usually used in high-speed aircraft to capture outside air and direct it to the aircraft to cool the engine compartment, which makes parts critical to the safety of the aircraft during flight.
3D printing“Flight critical” engine components
In recent years, many companies have developed engine parts that are essential to flight, that is, parts that are essential to aircraft safety, and some of them have even obtained certification for their end-use in commercial aircraft.For example, Honeywell Aerospace’s3D printing#4/5 bearing housing has been certified by the Federal Aviation Administration (FAA). The company’s aircraft components are the key structural components of the ATF3-6 turbofan engine used in the Dassault Falcon 20G maritime patrol aircraft.
Additive Flight Solutions (AFS) has cooperated with3D printingAircraft manufacturer Stratasys collaborated with Singaporean aircraft expert SIA Engineering Company (SIAEC) to obtain AS9100D certification for its parts. The certification shows that AFS components meet the strict quality management guidelines governing the aviation, aerospace and defense sectors.

The engine was tested by an unmanned aerial vehicle, and the speed of the drone is reported to reach 154 km/h.
