In recent years, 3D printing technology has developed rapidly. By combining with manufacturing methods such as NC machining, casting, metal cold spraying, and silicone mold, this technology has become an effective means to manufacture modern models, molds and parts. It has been used in aerospace, automobiles and motorcycles, household appliances, biomedicine, cultural creativity and other fields, and also occupies a unique position in engineering, teaching and scientific research.
1. industrial manufacturing: product conceptual design, prototype production, product review and functional verification; Make a mold prototype or directly print the mold and directly print the product. Conceptual products such as small unmanned aircraft and small cars printed in 3D have come out. 3D printed household appliance models are also used for corporate publicity and marketing activities;
2. Cultural creativity and digital entertainment: artistic expression carriers of complex shapes and structures and special materials. The sci-fi movie Avatar uses 3D printing to create some characters and props, and the 3D printed violin is close to the level of handicrafts.
3. Aerospace, national defense and military industry: direct manufacturing of parts and institutions with complex shapes, fine dimensions and special performance;
4. Biomedical treatment: artificial bones, teeth, hearing AIDS, artificial limbs, etc.
5. Consumer goods: design and manufacture of jewelry, clothing, footwear, toys and creative DIY works;
6. Building engineering: wind-driven experiment and effect display of building model, building engineering and construction simulation (AEC);
7. Education: the model verifies scientific hypotheses and is used in experiments and teaching of different disciplines. In some middle schools, universities and military academies in North America, 3D printers have been used for teaching and scientific research.
8. Personalized customization: Web-based e-commerce data download and personalized printing customization service.
Matters needing attention
When choosing a 3D printer, the key performance index of the device itself is also an important consideration index.
