In order to meet the requirements of design verification in the aerospace field, prototype processing is an effective technical means. To those special parts, 3D printing technology, a way of direct and quick prototyping, is a perfect embodiment of techniques.

In addition, the processing of appearance model with equal proportion is a very good supplementary technique for public presentation and wind tunnel test. Shanghai NewProductTechnologies has accumulated a wealth of experiences in assembly verification of cockpit and interior parts.
