In recent years,the rapid development of 3D printing technology,the rapid developmenthas been made invarious fields,has become an effectivemeans of modernmodels,moldand parts manufacturing,widely usedin aerospace,automobile and motorcycle,household appliances,biomedical and other fields,but alsoholds the unique status in thefield of Engineeringand teaching research.Specificapplicationsinclude1:mechanicalmanufacturing,3D printing technology to produce aircraft parts,bicycle,carparts,such asa rifle.2,the medical industry:in the medical field,with the help of 3Dprintdentures,femoral head,kneeand otherjointtechnology applicationis very wide,technology is more and moremature.3,the construction industry:engineers and designershave beenacceptedbybuilding3D modelprinter,thismethod is rapid,low cost,environmental protection,at the same time,produced exquisite,fully in line withthe requirements of designers,but alsocansave a lot of material.4,the automobile manufacturing industry:the3D printing technology to produceautomatic transmissioncar company.The carcompany will beall kinds of extremeconditionsto test thegearbox,some partsis to use 3Dprinting methodto do.Aftersetting,openmold,thenaccording to the traditionalmanufacturingmethods of mass production,so the costwill be greatly reduced.5,education:can be used in themodel to verifyscientific hypotheses,fordifferent disciplines,teachingexperiment.Some high schoolsin North America,thecolleges and universities andmilitary academies,3D printers havebeenused for teaching and scientific research.6,consumer goods: can be used injewelry,clothing,footwear,toys,creativeworksin the design and manufacture ofDIY.
