中英文資料（一） RP&M
1. What is RP&M
Manufacturing community is facing two important challenging tasks:
(1)substantial reduction of product development time; and （2） improvement on flexibility for manufacturing small batch size products and a variety of types of products. Computer-aided design and manufacturing（CAD and CAM） have significantly improved the traditional production design and manufacturing. However, there are a number of obstacles in true integration of computer-aided design with computer-aided manufacturing for rapid development of new products. Although substantial research has been done in the past for computer-aided design and manufacturing integration, such as feature recognition, CNC programming and process planning, the gap between CAD and CAM remains unfilled in the following aspects:
·rapid creation of 3-D models and prototypes.
·cost-effective production of patterns and moulds with complex surfaces.
To substantially shorten the time for developing patterns, moulds, and prototypes, some manufacturing enterprises have started to use rapid prototyping（RP）methods for complex patterns making and component prototyping. Over the past few years, a variety of new rapid manufacturing technologies, generally called Rapid Prototyping and Manufacturing（RP&M）, have emerged; the technologies developed include Stereolithography（SL）, Selective Laser Sintering（SLS）, Fused Deposition Modeling（FDM）, Laminated Object Manufacturing（LOM）, and Three Dimensional Printing（3-D Printing）. These technologies are capable of directly generating physical objects from CAD databases. They have a common important feature: the prototype part is produced by adding materials rather than removing materials, that is, a part is first modeled by a geometric modeler such as a solid modeler and then is mathematically sectioned（sliced）into a series of parallel cross-section pieces. For each piece, the curing or binding paths are generated. These curing or binding paths are directly used to instruct the machine for producing the part by solidifying or binding a line of material. After a layer is built, a new layer is built on the previous one in the same way. Thus , the model is built layer by layer from the bottom to top. In summary, the rapid prototyping activities consist of two parts: data preparation and model production.
2.The history of RP&M
As usual with invention, one individual’s impatience was the prototyping industry, now barely a decade old. Its father, Charles W Hull, 58 , still works as vice chairman and chief technology officer at the RP company he helped found in 1986, 3D Systems of Valencia, Calif. As an engineer, Hull had always been bothered by the long time it took to make prototype models of plastic. They had to be machined by hand, he recalls. If more than one was needed, generally the case in industry, molds for making plastic prototypes had to be individually machined.
The building blocks of a better system were lying around. Hull had been working for a small company that used ultraviolet lamps to substitute a laser for an ultraviolet lamp. “But taking that insight to a practical machine came slowly,” Hull recalls, and required several years of Edison-style inspiration. （In fact, a prototyping machine based on conventional UV light was developed in 1998 by The Institute of Advanced Manufacturing Technology, Xi’an Jiaotong University, China）.
The results was the first prototyping machine, introduced by 3-D Systems in 1987. It could fabricate small, transparent plastic parts from CAD drawings in hours or at most days. The machine builds the model in layers, from the bottom up. A laser, which causes molecules of a photosensitive liquid resin to polymerize, scans above a vessel filled with the resin. The laser first traces the outline of a layer on the resin’s surface. Next, like an artist shading a panel in a pencil drawing, the beam crisscrosses the whole outlined area to harden it. Then the platform holding the model sinks so the layer is barely awash in liquid resin, the laser goes to work solidifying another layer atop it, and so on. When the translucent object is done, it is raised from the vat, dripping like a mermaid just emerged from the sea.
Hull dubbed the process stereolithography, and it still dominates RP. The resins were, and still are very expensive: A gallon of acrylic blends of photo-curable liquids fetches about $750. But so great is industry’s hunger for prototypes, in an era when the pool of high-paid artisans who can make them by hand is shrinking and time to market is king, that designers were glad to get the first RP machines at any price. 3-D Systems has grown to an $80-million-a-year public company that’s still No.1 in the field by far.
Before long other inventors jumped in. Michael Feygin, an immigrant Russian engineer, hit on the idea of building prototypes from inexpensive slices of paper. His company, Helisys of Torrance, Calif., makes remarkably sturdy objects by a process called laminated-object manufacturing（LOM）.A blue CO2 laser traces each layer by burning, moving like a crazed ice dancer carving a turn here, a straight line there. Successive layers are bonded by adhesive. Helisys, whose machines have modeled auto steering wheels, bumpers, and other shapes that feel like wood to the touch, is a 12-million-a-year public company.
Meanwhile, a group of MIT inventors led by Emanuel Sachs, a slender, unassuming professor of mechanical engineering, chafed at the RP industry’s inability to make prototype, as well as molds and production parts, from ceramics and metal. The early RP machines could make a metal prototype only in a roundabout way. First a plastic model had to be “invested”, or clad in a heat-resistant material such as a ceramic. Then the model was “sacrificed” by melting, just as the ancient Egyptians melted a wax model inside a mold to clear the way for a bronze casting. This leaves a mold suitable for making a metal or plastic prototype.
Why not skip that stage, Sachs asked, and make sturdy parts directly from CAD designs? He and his 30-person shop at MIT have become the leaders in a branch of RP based on the same technique enabling computer printers to produce documents by squirting ink through jets. Instead of ink, MIT’s RP machines squirt a binder on layers of powdered steel, ceramics, or even starch that are spread by rollers.
The machines to which Sachs’ idea has given birth, called 3-D printers, are fairly inexpensive by RP standards, with low-end versions in the $50,000 range. The bigger 3-D printers are only now realizing Sachs’ goal of making commercially usable metal objects and molds directly from CAD designs. Soligen, a Northridge, Calif., company founded in 1992 by expatriate Israeli engineer Yehoram Uzirl, has developed, under license from MIT, the ink-jet machine Specific Surface employed to make those ceramic filters. On its machines, Soligen also makes ceramic molds, directly from CAD drawings, suitable for casting metal automotive parts that are as strong as those used in commercial products and suitable for testing and small production runs.
Soligen’s process still has limitations. The ceramic molds are made in one piece and can only be used once, since they must be destroyed to get at the part. But Soligen can make lots of molds quickly as needed. Many RP users, eager to go further, want rapidly made molds that can be used over and over for mass production. That would shrink the manufacturing middle some more, bypassing a conventional process in which a long-lasting mold is carefully carved out of a block of high-grade steel with CNC and other machines, then painstakingly finished by hand, a process that can take months.
Quickly made reusable molds, which put RP squarely in rapid-manufacturing territory, have started to appear. When Rubbermaid Office Products of Maryville, Tenn., got an urgent order in 1996 from Staples, the office-products chain, for a small plastic stand that holds sheets of paper vertically, Rubbermaid went to an RP service bureau in Dallas that had a machine made by DTM of Austin, Texas. The ten-year-old company, whose initials stand for “desk top manufacturing,” has developed a sintering process in which loosely compacted plastic are heated by a laser to combine with powdered steel, layer after layer, into a solid mass.
The DTM machine speedily produced a metal mold from which Rubbermaid was able to make more than 30,000 plastic stands for staples, priced at $3. Says Geoff Smith-Moritz, editor of the newsletter Rapid Prototyping Report in San Didgo:“ Though not very impressive looking, this product is a pioneer. More and more molds are being made this way.”
In its purest form, rapid manufacturing would eliminate molds: Machines would fabricate products directly from CAD designs. Extrude Hone, a company in Irwin, Pa., is getting ready to market a machine, based on MIT’s ink-jet technology, that will make not only metal molds but also salable metal parts. In Extrude Hone’s machine, powdered steel is hardened with a binder and infiltrated with bronze powder to create a material that is 100% metal.
Powerful new laser may also open doors to direct manufacturing. Such laser systems are being explored at national laboratories such as Sandia and Los Alamos, as well as at the University of Michigan, Penn State, and elsewhere. They may soon be available commercially. In the Sandia system, a 1,000-watt neodymium YAG（yttrium-aluminum-gallium）laser melts powdered materials such as stainless and tool steels, magnetic alloys, nickel-based superalloys, titanium, and tungsten in layers to produce the final part. The process is slow: three hours to make a one-cubic-inch object. But the part is just as metallically dense as one made by conventional means. Sandia vic president Robert J. Eagan says the lab’s researchers hope to see the process used to make replacement parts for the military’s stored nuclear weapons. Commercial interest is high too. Ten companies, including AlliedSignal and Lockheed Martin, are participating in the program. Another 20 companies support research at Penn State, where the goal is to make big objects, such as tank turrets and portions of airplanes, as a single part.
Some experts look to a manufacturing future extensively liberated from today’s noisy, hot routines. Instead of molds and machine tools, these visionaries foresee rows of lasers building parts, 3-D printers fashioning convoluted shaped no CNC machine can carve, and silent ceramic partsmakers replacing the traditional noisy factory din. Many products turned out in future factories could be designed to take advantage of rapid-manufacturing techniques. Implantable drug-release devices, with medicine sealed in, could be made in a single operation, since 3-D printers can make a sandwich-like product.
Manufacturing pioneers find such possibilities intoxicating.“We could have naval ships carry not an inventory of parts but their images digitized on a 3.5-inch diskette, plus a bag of powdered metal and a rapid manufacturing machine,”says 3-M’s Marge Hartfel.Adds Brock Hinzmann, director of technology assessment at SRI International:“In two or three years rapid manufacturing will be on everybody’s lips.”In the meantime, the feats of fast prototyping are giving the factory folks plenty to talk about.
3. Current application areas of RP&M
Although RP&M technologies are still at their early stage, a large number of industrial companies such as Texas Instruments, Inc., Chrysler Corporation, Amp Inc. and Ford Motor Co. have benefited from applying the technologies to improve their product development in the following three aspects.
（1）Design engineering
1)Visualization. Conceptual models are very important in product design. Designers use CAD to generate computer representations of their design concepts. However, no matter how well engineers can interpret blue prints and how excellent CAD images of complex objects are, it is still very difficult to visualize exactly what the actual complex products will look like. Some errors may still escape from the review of engineers and designers. The touch of the physical objects can reveal unanticipated problems and sometimes spark a better design. With RP&M, the prototype of a complex part can be built in short time, therefore engineers can evaluate a design very quickly.
2)Verification and optimization. Improving product quality is always a important issue of manufacturing. With the traditional method, developing of prototypes to validate or optimize a design is often time consuming and costly. In contrast, an RP&M prototype can be produced quickly without substantial tooling and labour cost. Consequently, the verification of design concepts becomes simple: the product quality can be improved within the limited time frame and with affordable cost.
3)Iteration. Just like the automotive industry, manufacturers often put new product models into market. With RPA&M technology, it is possible to go through multiple design iterations within a short time and substantially reduce the model development time.
快速原型制造和制造業(yè)
1、RP&M是什么了呢？
制造業(yè)團體面臨著兩項重要的富有挑戰(zhàn)性的任務：
(1) 大量的減少了產品的開發(fā)時間； (2)提高了制造小批量產品和各種各樣類型的產品的制造業(yè)的靈活性。 計算機輔助設計和制造業(yè)(CAD和CAM)顯著改進了傳統(tǒng)生產設計和制造業(yè)。然而，為新產品的迅速發(fā)展，對于確切地整合計算機輔助設計與計算機輔助生產，有許多的障礙。盡管在過去對計算機輔助設計和制造業(yè)整合進行了大量的研究，例如特征識別，CNC編程和處理計劃，CAD和CAM之間的空白在以下方面依然是未填充：
·三維模型和原型的迅速創(chuàng)作。
·有復雜表面的樣式和模子的有效成本的生產。
極大地縮短了為開發(fā)樣式，模具和原型的時間，一些制造業(yè)企業(yè)開始使用快速的原型機制造方法用于制作復雜的樣式做和原型機制造組件。在過去幾年里，各種各樣的新的快速的制造業(yè)技術，一般被稱作快速原型制造和制造業(yè)（RP&M）已經形成了；被開發(fā)的技術包括立體平版印刷術(SL)，有選擇性的激光焊接(SLS)，被熔化的沉積物塑造(FDM)，分層物體的制造業(yè)(LOM)和三維空間打印(三維打印)。這些技術具有直接地從CAD數(shù)據(jù)庫中生成實體的能力。他們有一個共同的重要特點：原型機零件是通過增加材料而不是取消材料來生產的，即，零件首先要被制成幾何學的模型，然后被劃分成(切成)一系列的平行的短剖面片斷。對于每個片斷，都要就行紅外線固化或是裝訂路徑。這些紅外線固化或裝訂路徑通過凝固或是綁定一系列的材料直接地被用來指導生產零部件的機器。在層數(shù)被建立之后，新的層數(shù)將會以相同的方式早先被建立。 因此，模型是被從底部到頂端一層一層地建立。總之，快速的原型機制作活動包括兩部分：數(shù)據(jù)準備和模型生產。
2、快速原型制造和制造業(yè)（RP&M）的歷史
像平常一樣的發(fā)明，一個人的不耐煩是原型制造產業(yè)，現(xiàn)在僅僅十年的樣子。其父親，查爾斯瓦特赫爾，58歲，仍是工程副委員長和技術總監(jiān)，在1986年幫助他發(fā)現(xiàn)了RP公司，加利福尼亞3D巴倫西亞系統(tǒng)。 作為工程師，赫爾很懊惱因為他花了很長時間用塑料來制作原型機的模型。他們必須親自加工，他回憶說。 如果有一個以上的需要，一般情況下在企業(yè)里的情況是，做塑料原型的模子必須單獨地用機器制造。
在四周矗立一個更好的系統(tǒng)的建筑群。赫爾一直致力于為一家小公司而工作，這家小公司過去常常使用紫外光燈替代紫外激光燈?！暗沁@種做法對于了解一個實用機器變得很緩慢，”赫爾回憶道，并且需要幾年愛迪生式的啟發(fā)。(實際上，在1998年基于常規(guī)紫外光的原型制造機已經形成了，這是由中國西安交通大學先進的制造業(yè)技術研究院主導的。)
結果是第一個原型制造機器，在1987年引進了三維系統(tǒng)。 它可以示在幾小時或好幾天的時間里用CAD畫圖，制造出小的、透明的塑料部分。機器在層上建立模型，從下到上。激光，可以造成光敏液體樹脂分子聚合，并且在充滿樹脂的容器之上掃描。 接著，它可以像一個藝術家一樣用素描在面板上留下底紋，射線在整個大致的區(qū)域交叉往來以使它硬化。然后讓這個平臺將模型沉下去，因此有著層數(shù)的平臺是幾乎不可能充滿液體樹脂的，激光繼續(xù)起作用在它上面去另一層工變硬，等等。當半透亮的物體形成時，水滴就像是從海底涌現(xiàn)出來的美人魚一樣。
赫爾復制了立體平版印刷術的過程，并且它仍然控制著RP。樹脂仍然是非常昂貴的：一加侖的丙烯酸酯用可醫(yī)治的液體的混合可售得大約750美元。但更重要的是企業(yè)對原型制造機的渴求，在這樣一個時代里，有著大量的高薪酬的能工巧匠們正在減少，上市的時間是很寶貴，設計師們很高興得到第一個RP機器的以所有價格。 三維系統(tǒng)已經成長為每年都有八千萬股票公開的上市公司，這個公司在將來在它所屬的領域仍然會是第一位的。
不久以后其他發(fā)明者開始跳槽。邁克爾Feygin，一位移民的俄國工程師，偶然間有了這么一個用低廉的切片紙建立原型機的想法。他的公司，托蘭斯Helisys，位于加利福尼亞，靠被稱作是碾壓對象生產(LOM)的程序取得了顯著的成果。藍色二氧化碳激光器通過燃燒、移動追蹤著每個層數(shù)，像一位在這里雕刻輪的瘋狂的冰上舞蹈家一樣，像那里的一條直線。連續(xù)層數(shù)由膠粘劑結合。Helisys，它的機器已經形成了自動方向盤、防撞器和感覺觸摸起來像木頭一樣的其他形狀的模型，是每年都有1200萬公開股票的上市公司。
同時，這個MIT發(fā)明者的小組是由Emanuel ? Sachs領導的，他是一位身材勻稱的，不擺架子的機械工程教授，對于RP產業(yè)從陶瓷和金屬起，就沒有能力做原型制造機以及模子和生產零件，他甚是憤怒。早期的RP機器只能用一種環(huán)形交叉的方式來做一個金屬原型制造機。首先塑料模型必須“被投資”或者像陶瓷一樣用一種耐熱材料來覆蓋。然后模型通過熔化就“犧牲”了，就像古埃及人在模子里面熔化蠟模為一個古銅色鑄件掃清道路。這種遺留下來的很適合做金屬或塑料原型制造機。
為什么沒有跳躍那個階段，塞克斯問道，并且直接地由CAD設計做出實用性的零件？他和他的在MIT里銷售的30個人成為了RP分支里的領導，其根據(jù)相同的技術使計算機打印機通過噴氣機噴射墨水來打印文件。而不是墨水，MIT的RP機器在噴一種研成粉的鋼、陶瓷，甚至淀粉的層數(shù)的黏合劑。
三維打印機的機器誕生了，這種機器是采用相當?shù)土腞P標準，以終端版本是在$50,000的范圍內。更大的三維打印機現(xiàn)在可以明確地實現(xiàn)塞克斯的目標，只能用做商業(yè)用的直接地由CAD設計出來的金屬實體和模型。Soligen， 諾斯里奇，加利福尼亞，公司始建于1992年，是由移居國外的以色列工程師Yehoram Uzirl創(chuàng)立的，在根據(jù)MIT的特許下已經開發(fā)了噴墨打印，個別機器的表面用來做那些陶瓷過濾器。使用它的機器，Soligen直接地由CAD畫圖做出了陶瓷模型，適合于像那些用于商用的產品一樣堅硬的鑄件的金屬汽車零件和適合于為測試和小生產運行。
Soligen的過程仍然有限制。因為必須毀壞他們獲取零部件，陶瓷模子被做成一整件，并且僅能使用一次。但Soligen能夠按照需要迅速地做出全部模子。許多RP用戶，渴望走的更遠，想要可以為大量生產多次使用的迅速地被制作的模子。那將收縮制造業(yè)中部有些，繞過一個個常規(guī)過程，持久模子用CNC和其他機器精心地雕刻在高等級鋼外面塊，然后用手費力地完成，過程可能需要幾個月。
迅速被制作的可再用的模子，將RP直接地投入到了快速制造業(yè)領域，已經開始出現(xiàn)。當馬利維樂博美辦公用品，田納西州，在1996年從史泰博得到了主要的訂單，這是一家辦公室產品連鎖店，對于一家小型的塑料展臺它可以直接地保存大量的材料， 樂博美有克薩斯奧斯汀的DTM制造的機器，去達拉斯的一個RP服務處。十年的老公司，最初代表“桌面制造業(yè)”，開發(fā)了焊接過程，松散地用激光器加熱將研成粉的鋼組合從而變緊密塑料，逐層地加固。
DTM機器迅速地生產了一個金屬模子，樂博美能使用原料做超過30,000個塑料展臺的，定價在3美元。杰夫.史密斯.莫里茲，他是圣Didgo的一位做迅速成型制造機報告的時事通訊編輯，他說：“雖然看起來印象不非常深刻，但是這種產品是先驅。 越來越多的模子被用這種方式來制作”。
以它最抽象的形式，迅速制造業(yè)將剔除模子：機器將能使用CAD設計來直接地制造產品。Extrude Hone，是一家巴拿馬歐文的公司，將準備好基于MIT的噴墨機技術來銷售機器，將不僅做金屬模子，而且也做暢銷的金屬零件。在Extrude Hone的機器中，研成粉的鋼將會用夾器和滲入粉末狀的青銅來使其變硬，創(chuàng)造出100%金屬的材料。
強有力的新的激光器也許為直接制造業(yè)敞開著大門。這種激光器系統(tǒng)在像桑迪亞和洛斯阿拉莫斯的國家實驗室里被探索著，除了在賓西法尼亞州的密歇根大學外，還有其他地方。他們也許很快就會在商業(yè)上適用。 在桑迪亞系統(tǒng)中， 1,000瓦特釹YAG (釔鋁鎵) 激光器融解在層里熔接粉末狀的材料例如不銹和工具鋼、磁性合金、基于鎳的超耐熱不銹鋼、鈦和鎢，目的是為了生產最后的零部件。過程是很緩慢的：做一立方體英寸的物體需要三個小時。但零件通過常規(guī)手段做的很密實。桑迪亞副總裁羅伯特J. 愛德華說實驗室的研究員希望看到這么一個過程用為軍事目的而被存放的核武器的替代品。商業(yè)利益也是很高的。十家公司，包括聯(lián)信公司和洛克希德馬丁公司，都參與到了這個項目里來了。另外20家公司也支持在賓夕法尼亞州得研究，目標是做大物體，例如坦克的塔樓和飛機的部件，作為單件。
有些專家看到從今天喧鬧的，熱的常規(guī)性工作中解放出來的制造業(yè)的更加廣泛的未來。而不是模子和機床，這些有遠見者預見激光器的建筑零部件，三維打印機的回旋收放針，CNC機器的雕刻成形的，安靜的陶瓷部件制造廠將會替換傳統(tǒng)喧鬧的工廠。利用迅速制造業(yè)技術，許多產品在未來工廠中被證明是能夠被設計的。因為三維打印機可能做像三明治一樣的產品，可植入釋放藥物的設備，當醫(yī)學被密封，可能做在一次簡單的操作。
制造業(yè)先驅們發(fā)現(xiàn)這種可能性很令人陶醉。“我們可能安排軍艦運載不僅僅是零件，還可以是他們3.5英寸磁盤數(shù)字化的影像，加上大量的粉末狀的金屬和快速的制造業(yè)機器”， 3M的Marge Hartfel.Adds Brock Hinzmann， SRI國際技術評估的主任，他說：“在兩三年內迅速制造業(yè)將是在大家經常談論的事情?！蓖瑫r，快速成型機的壯舉將會給予給工廠伙計們豐足談論。
3、當今RP&M的適用領域
盡管RP&M技術還仍然處于早期階段，但是大多數(shù)的工業(yè)公司諸如德洲儀器公司，克萊斯勒公司， 安普公司和福特汽車公司已經受益于申請技術改進他們的產品開發(fā)，主要表現(xiàn)在以下三個方面
（1）工程設計
1）可視化。概念型的模型在產品設計中是非常重要的。設計師使用CAD來使他們的設計觀念在計算機中表示。然而，無論好的工程師怎么解釋藍圖打印方案及復雜的實體是多么好的CAD圖象，將看起來實際復雜的產品確切地形象化仍然是非常難的。有些錯誤也許在工程師和設計師的檢查過程中仍然會漏掉。對實體的接觸可能會顯露意外的問題和有時會激發(fā)一個更好的設計。由于有了RP&M，某種復雜部件的原型制造可以在很短的時間里建立，所以工程師們也就可以非常迅速的評估一項設計。
2）檢驗和優(yōu)化。提高產品的質量一直以來都是制造業(yè)中的一項重要的課題。與傳統(tǒng)的方法相比，確認或者是優(yōu)化一項設計的原型機的發(fā)展通常是很耗時并成本挺高的。相比之下，這種RP&M的成型機可以在沒有充足的工具和勞動力成本下快速的生產。結果是，設計概念的檢驗變得很簡單：產品質量在有限的時間框架和可以支付的成本條件下得到了提高。
3)循環(huán)。就像自動化工業(yè)一樣，制造商們通常會把新產品模型推向市場。由于有了RPA&M技術，在短時間內進行多次的設計循環(huán)并且大量的減少模型的研發(fā)時間成為可能。
