The Eiges you mentioned is really an expert in nonmetallic materials. As far as I know, they use SLS laser sintering, which is also a relatively advanced process at present. If manufacturers want more equipment costs, they have a variety of materials to choose from. They should choose materials according to their working conditions. If they don't know, they can directly find their salesperson information. Igos has resident sales staff in major cities in China, which should be more convenient, or you can call directly for consultation. Telephone numbers can generally be found in official website.
