What is laser rapid prototyping? It is a new manufacturing technology integrating advanced technologies such as CAD, cam, CNC, laser, precision servo drive and new materials. Different from the traditional manufacturing methods, laser rapid prototyping has high reproducibility and interchangeability of prototypes; It has the advantages of simpler manufacturing process, short processing cycle and low cost, so as to realize the integration of design and manufacturing.

激光快速成型經歷了怎樣的發展歷程呢？為此，小編請教了嘉瑞杰快速成型技術有限公司的人士，得知近期發展歷程主要如下：立體光造型(SLA)技術；選擇性激光燒結(SLS)技術；熔絲堆積成形（FDM）技術；激光熔覆成形（LCF）技術；激光近形（LENS）技術；激光薄片疊層制造(LOM）技術；激光誘發熱應力成形（LF）技術及三維印刷技術等。這些技術被廣泛應用于各行各業，且讓人刮目相看！

What is the development process of laser rapid prototyping? To this end, Xiaobian consulted people from jiaruijie Rapid Prototyping Technology Co., Ltd. and learned that the recent development process is mainly as follows: stereo light modeling (SLA) technology; Selective laser sintering (SLS) technology; Fuse stacking forming (FDM) technology; Laser cladding forming (LCF) technology; Laser near form (lens) technology; Laser laminated sheet manufacturing (LOM) technology, laser induced thermal stress forming (LF) technology and three-dimensional printing technology, etc. these technologies are widely used in all walks of life and make people look at them with admiration!

那激光快速成型的應用前景如何呢？在一些發達，如美國、日本、德國、比利時等都投入了大量的人力、物力研究該技術，并不斷有新產品問世，引起世界的矚目。我國也不甘落后，或是研究機構，或是校園都在激光快速成型方面投入人力、物力，積極研究。

What is the application prospect of laser rapid prototyping? In some developed countries, such as the United States, Japan, Germany, Belgium, etc., a lot of human and material resources have been invested in the research of this technology, and new products have come out continuously, which has attracted the attention of the world. China is not willing to lag behind, either professional research institutions or campuses have invested human and material resources in laser rapid prototyping Research.

汽車行業就應用了激光快速成型技術，如車身制造中應用SLA技術，可制造出所需比例的精 密鑄造模具，從而澆鑄出一定比例的車身金屬模型；利用此金屬模型可進行風洞和碰撞等試驗，對車身進行評價，判斷設計是否合理。

Laser rapid prototyping technology is applied in the automotive industry. For example, SLA technology is applied in body manufacturing, which can manufacture the precision casting mold with the required proportion, so as to cast a certain proportion of body metal model; using this metal model, wind tunnel and collision tests can be carried out to evaluate the body and judge whether the design is reasonable.

除此之外，在汽車發動機進氣管試驗中，激光成型技術也發揮了重要作用。眾所周知，進氣管的內腔形狀十分復雜，由自由曲面構成；但對進氣效率、燃燒過程有著十分重要的影響。因此，在設計過程中會進行多次試驗，但傳統的方法會產生顯著的誤差，可能是對圖紙的理解錯誤或技術水平的限制，但激光成型技術就能有效降低誤差，達到滿意的效果。

In addition, laser forming technology also plays an important role in the test of automobile engine intake pipe. As we all know, the inner cavity shape of intake pipe is very complex, which is composed of free-form surface; but it has a very important impact on intake efficiency and combustion process. Therefore, many tests will be carried out in the design process, but the traditional methods will produce significant errors, which may be harmful to the combustion process The drawing is misunderstood or limited by the technical level, but the laser forming technology can effectively reduce the error and achieve satisfactory results.
