Laser shapes quickly technical research and application
About laser the research of fast figuration technology basically is in following undertake on 3 respects:
The first, material.
Material is the core of fast figuration technology, a kind of any fast forming machine study development comes out in the light of the material of specific sort or specific configuration, colophony of liquid state photosensitive uses SLA, paper uses LOM, filiform material uses FDM, pulverous account data uses SLS, hear of recently developing a kind of new laser again fast forming machine, those who use is gaseous material -- a kind of active gas, this kind of active gas happens below laser action decompose, on workbench deposit gives one layer upon layer pottery and porcelain or the metal forms workpiece.
Additional, people is at present fast to laser the expectation with figuration the oldest technique, the figuration that pledges in the different capable person that needs at forming people place directly, be like plastic, metal etc. Even if break up secondhand make, also want to solve relevant data and craft problem. Of material cheap changing also is a research key.
The 2nd, equipment.
The device that says here, include hardware not only, namely laser is fast forming machine itself, and include corresponding software, the interview before be like arrives how to have section to three-dimensional CAD software directly, avoid STL format file this handles link approximately, its purpose is the figuration precision that raises forming machine and figuration efficiency.
The 3rd, application.
Laser is in into form technology quickly the application in each domains is wider and wider, among them the mainest application has the following sides:
1, the application in products plan
Make appearance quickly, although go up to have difference with final real product character in material but because appearance and dimension precision are tall, can use the figure that has a product and dimension judge, can undertake partial performance checks even, compare with traditional production prototype photograph, save time substantially not only, 100 and substantially managing charge.
Fast figuration technology is measured with 3 coordinate, union of CT of three-dimensional laser scanning, industry is used, still can carry out quickly beg instead (converse) project.
2, medium application is made in the mould
(1) fast figuration use as directly mould
The paper model that LOM makes replaces the wooden model that sand mold casts directly via finishing, to the high accuracy pattern with mixed appearance, its advantage is highlighted particularly.
The paper pattern that LOM makes uses as directly via finishing the figuration model that alloy of low melting point casts model, trial-produce to use the model that note model or the wax-pattern in breaking candle to cast.
