The manufacturing capacity and level of aerospace parts and components are an important manifestation of the country's industrial and technological strength. As a high-end equipment manufacturing industry with huge development potential and a high technical threshold, the aerospace manufacturing industry has a strong industrial driving ability.
With the in-depth application of metal 3D printing technology in the development stage of aerospace parts, the need for mass production using metal 3D printing technology has become increasingly prominent. Especially in recent years, the rapid development of domestic and foreign commercial aerospace, the continuous innovation of satellite technology, and the continuous improvement of manufacturing capabilities; the iterative acceleration of new models of civil aviation products, all of which have put forward higher requirements for the high-quality batch manufacturing capabilities of the supporting industry chain. Require.
Due to the harsh service conditions of aerospace parts, the material selection of each component and the performance requirements of the parts are different, resulting in difficult research and development of aerospace parts, long production cycles, difficult product delivery, and high cost of the whole machine. The use of metal 3D printing technology can realize the rapid manufacture of key aerospace components, shorten the test time, speed up the technical iteration and program verification time, and improve development efficiency. The proven aerospace parts have good quality and accuracy and meet the requirements of mass production.
Blite integrates years of experience in metal 3D printing, continuously carries out technological innovation, improves technology, and provides high-quality 3D printing equipment for the mass production of aerospace parts. Taking the inner streamer of the Winter Olympic torch printed by BLT as an example, the inner streamer adopts the engine power principle, the outer side has a variable surface structure pattern, and the inner side has a connecting structure to connect with the flame combustion device. The height of the streamer parts in the torch is 414mm, which is a thin-walled structure with a special-shaped curved surface. All inner streamers are printed in one piece by BLT-S515 four-light equipment. One oven can print 36 pieces, which takes 50 hours to complete. The inner and outer surfaces of the inner streamer product are dense and defect-free, the ridges are complete, and uniform, there is no dislocation such as faults, and the appearance of the product has no visible defects to the naked eye.
At the 14th China Air Show in 2022, Blite will display the "full cabin batch production" mounting bracket. The mounting bracket is a display part designed from the deformation of a part of a drone. The part is a topology optimized structure, the bottom is a thin-walled cylinder, and the top is a scattered rib shape. The whole part is self-shaped without adding auxiliary support. The size of the full version of the mounting bracket is 250mm×400mm×400mm and the weight is 4.12kg. BLT-S400 Sanguang equipment can form 40 pieces of full-plate mounting brackets at one time, and the time only takes 83 hours. The parts are filled with the substrate in the horizontal direction, and four layers are stacked in the vertical direction, making full use of the forming space of the equipment. The formed mounting bracket parts have high quality, consistent performance, and good dimensional accuracy, demonstrating the BLT-S400's ability to "reduce cost and increase efficiency" for the mass production of aerospace components.
A full-plate support frame for parts showing the mass production process capability will also be featured at this air show. The support frame is made of titanium alloy material and has a topology-optimized structure. The main structure is rib-shaped with a large aspect ratio. The forming angle of many structures is small. Tree-like supports are added, and grid-like supports are added in some areas to ensure structural stability. The size of the full support frame is 250mm×400mm×400mm and the weight is 5.92kg. Using the BLT-S400 Sanguang equipment, it can form 12 pieces at a time, and it only takes 40 hours.
As a flagship batch production equipment, BLT-S400 is proven, stable and reliable. The forming efficiency of its three-laser configuration can reach 75cm³/h, and the production capacity is higher. BLT-S series equipment is equipped with intelligent modules such as intelligent powder coating detection and 3D reconstruction. Intelligent powder coating detection can monitor the powder coating process in real-time, intelligently identify various powder coating abnormalities, and repair them according to the database, which ensures the high quality of formed parts. 3D reconstruction can quickly identify forming defects and display the formed parts in real-time, which is convenient for later quality retrospection.
JR is also equipped with BLT-S400 3D printing equipment, which can provide customers with metal 3D printing services in industries such as aerospace and automotive.
