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(jīng)歷了怎樣的發(fā)展歷程呢？為此，小編請(qǐng)教了嘉瑞杰快速成型技術(shù)有限公司的人士，得知近期發(fā)展歷程主要如下：立體光造型(SLA)技術(shù)；選擇性激光燒結(jié)(SLS)技術(shù)；熔絲堆積成形（FDM）技術(shù)；激光熔覆成形（LCF）技術(shù)；激光近形（LENS）技術(shù)；激光薄片疊層制造(LOM）技術(shù)；激光誘發(fā)熱應(yīng)力成形（LF）技術(shù)及三維印刷技術(shù)等。這些技術(shù)被廣泛應(yīng)用于各行各業(yè)，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(yīng)用前景如何呢？在一些發(fā)達(dá)，如美國(guó)、日本、德國(guó)、比利時(shí)等都投入了大量的人力、物力研究該技術(shù)，并不斷有新產(chǎn)品問世，引起世界的矚目。我國(guó)也不甘落后，或是研究機(jī)構(gòu)，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(yè)就應(yīng)用了激光快速成型技術(shù)，如車身制造中應(yīng)用SLA技術(shù)，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(jìn)行風(fēng)洞和碰撞等試驗(yàn)，對(duì)車身進(jìn)行評(píng)價(jià)，判斷設(shè)計(jì)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(fā)動(dòng)機(jī)進(jìn)氣管試驗(yàn)中，激光成型技術(shù)也發(fā)揮了重要作用。眾所周知，進(jìn)氣管的內(nèi)腔形狀十分復(fù)雜，由自由曲面構(gòu)成；但對(duì)進(jìn)氣效率、燃燒過程有著十分重要的影響。因此，在設(shè)計(jì)過程中會(huì)進(jìn)行多次試驗(yàn)，但傳統(tǒng)的方法會(huì)產(chǎn)生顯著的誤差，可能是對(duì)圖紙的理解錯(cuò)誤或技術(shù)水平的限制，但激光成型技術(shù)就能有效降低誤差，達(dá)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.
