Aerospace Application

Each kilogram reduction of spacecraft could lower the launch costs 20,000 US dollars, thus each gram in lightweight design counts. Traditional structure design is limited by the processing ability of the traditional processing technology and could only be designed with experience and accumulation, which likely cause problems such as uneven force or material distribution. With optimized structure of topological design, metal 3D printing technology could not only satisfy functional and rigidity needs, but also enhance strength, reduce local stress, reduce weight at remarkable level, achieve more uniform load, and realizing material evenly and rationally distributed. Metal 3D printing technology could process any complicated structures, while manufacturing cost is independent from the structure complexity, breaking the shackles of the traditional processing technology, which provides a more flexible degree of freedom for structural optimization design, especially for topology optimization design of complex geometric processing components.

1. No complicated traditional processing procedures, no need to use any molds, directly convert the design drawings into real objects, greatly shorten the parts’ preparation cycle, improve the R&D efficiency.

2. Multiple parts can be multidimensional composited, to realize the integration of multi-parts and complex structures, and improve production efficiency.

3. In aerospace field, where raw materials are extremely expensive, the raw material utilization rate in traditional subtractive manufacturing is low, and raw materials cannot be recycled directly, thus eventually increase the manufacturing cost. Metal 3D printing technology has a higher material utilization rate, and the used raw materials can be recycled with simple post-processing procedures, thus reduce production costs.
