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.

激光快速成型经历了怎样的发展历程呢？为此，小编请教了嘉瑞杰快速成型技术有限公司的人士，得知近期发展历程主要如下：立体光造型(SLA)技术；选择性激光烧结(SLS)技术；熔丝堆积成形（FDM）技术；激光熔覆成形（LCF）技术；激光近形（LENS）技术；激光薄片叠层制造(LOM）技术；激光诱发热应力成形（LF）技术及三维印刷技术等。这些技术被广泛应用于各行各业，且让人刮目相看！

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!

那激光快速成型的应用前景如何呢？在一些发达，如美国、日本、德国、比利时等都投入了大量的人力、物力研究该技术，并不断有新产品问世，引起世界的瞩目。我国也不甘落后，或是研究机构，或是校园都在激光快速成型方面投入人力、物力，积极研究。

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.

汽车行业就应用了激光快速成型技术，如车身制造中应用SLA技术，可制造出所需比例的精 密铸造模具，从而浇铸出一定比例的车身金属模型；利用此金属模型可进行风洞和碰撞等试验，对车身进行评价，判断设计是否合理。

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，在汽车发动机进气管试验中，激光成型技术也发挥了重要作用。众所周知，进气管的内腔形状十分复杂，由自由曲面构成；但对进气效率、燃烧过程有着十分重要的影响。因此，在设计过程中会进行多次试验，但传统的方法会产生显著的误差，可能是对图纸的理解错误或技术水平的限制，但激光成型技术就能有效降低误差，达到满意的效果。

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.
