1358358 、發明說明： 【發明所屬之技術領域】 本發明有關於快速原型（Rapid pr〇t〇typing，Rp)技 術’尤其疋以薄片積層法（Laminated州㈣ Manufacturing，LOM)為基礎的多種材料之薄片 速原型系統及方法。 s $ 【先前技術】1358358, invention description: [Technical field of the invention] The present invention relates to Rapid pr〇t〇typing (Rp) technology, in particular, a variety of materials based on the laminating method (Laminated State Manufacturing, LOM). Sheet speed prototype system and method. s $ [previous technology]
快速原型系統發展至今，已廣泛被工業界接受和使 用。此技術具有工時短，精度佳，加工路徑不受限制 優點，能快速且精確製出原型物件，特別適合應用 業設計及製造產業中，生命週期短，少量多樣的產品。 其原巧製品可作為產品設計的外型驗證、功能測試以及 輔助杈具開發之用，因此可迅速地輔助產品進行開盘 =低開模製作時可能發生之錯誤風險，有效縮短開^ 時間與降低成本，使得產品更具競爭力。 X 然而’對於新世代之快速原型技術的發展而言，Rp 不再只是快速製作原型的代名詞，而有一全新名詞，稱 為快速生產或快速製造。因此如何跳脫以往只侷限於穿 =外觀參考的原型，而能快速製作具功能性元^ unctional Parts) ’ 如嵌入件（jnsert)、組合 (Assembly)、及具有多種材質（Multi Material)之 里，乃目刖快速原型技術的重要研究課題。 ’、 P快之應用包羅萬象，目前不僅工業上之應用 ^夕更推展至醫學、藝術、地理資訊及人文科學等。 應用最成熟之工業原型與模型為例，大抵應用 ^供汉计驗證之概念原型（Concept Model)上，至於作為 模型因要求較高之強度及硬度’只有 乂数的機種適用。然而若以快速原型機器之昂貴價格 4 [51 1358358 僅達此概念原型之應用，則其適用性必然受限。再者， 由於近年來市場上之產品生命週期愈來愈短，企業界務 巧快速原型技術將產品開發之時程縮短，以提高產 品競爭力與市場佔有率。所以快速原型技術除了要提供 快速正確的外形樣品外，更要能使之具有功能性，才能 使快速原型技術的應用更為廣泛。 請參考第一圖，快速成型的原理為，當初步設計的 ，念用電腦三為電腦輔助設計（3D CAD)完成後，傳統上 疋用手工或機械式的方式，根據二維加工圖，將原型製 來，這種方式須進一步設計夾具或模具，整個過程 常花費許多人力及物力，若製造出來之原型顯示出錯 誤，則整個過程勢必重新再來。若使用快速原型技術， 則I將3D CAD上之三維立體圖型與一層層之二維平面 相父，。交集之結果即得一疊二維之幾何數據，每一片 表示二維立體圖形之截面。接下來，電腦取出最底端的 片4何圖型，作為電腦定位控制之用，將能量源及原 始材料傳至工作面，把原料加在幾何圖形所指示的位置 上，依此程序，由底端至頂端，逐片把原料填上而結合 在一起，完成後即可取出所製成之立體原型。理論上， 當一層層的二維薄片很薄時，立體原型和原來電腦所建 立的立體幾何圖型會一模一樣 快速原型技術亦可稱為加料製程技術（Material Increase Mamifactoing)，或層加工技術（Layer Manufacturing Technology) ’ 或實體自由成型技術(s〇nd Freeform Fabrication)，這是因為它的加工方法有別於傳 統之去料加工法，如車床、銑床、磨床、鉋床等，快速 原型是採用將材料層層添加堆積而成。一般而言，快速 原型可依使用的材料分成粉.末、液態樹脂、固體材料三 大類’各有其不同之特長及應用領域。 在固體材料成型方面’一般是使用片狀材料黏著 5 1358358 (Gluing Sheets)的方式加工，從加工原理看來，任何可 製成片材的材料均可用這種方法，但因為能量裝置、廢 料剝除及工件定位等因素的限制，目前大都使用紙張為 主，較為知名的廠商有美國CUBIC公司的薄片積層法 (Laminated Object Manufacturing, LOM)、日本 KIRA 公 司的選擇性黏著與熱壓法（Selective Additive and Hot Press, SAHP)，目前新加坡KINRGY公司亦有與LOM 相似的Zippy機器。 請參考第二圖，是一傳統LOM製程之流程圖。一 般典型LOM是採用紙張作為原料，因為紙是採用木材 • 製成的’所以L〇M的成品與木製品非常相似，LOM屬 於加料方式（Additive Method)及減料方式（Subtractive Method)的一種混合加工，這是與其他rP機器，大都採 用加料方式加工最大不同之處。其加工流程如下： - STEP 1:紙張往前推進，直到覆蓋整個工作台為止。 STEP2 :床台上昇接觸到紙張，碰觸到z轴的極限 開關（Limit Switch)以控制一定的高度。Rapid prototyping systems have been developed and used by the industry today. This technology has the advantages of short working hours, high precision, and unrestricted processing path. It can quickly and accurately produce prototype objects, especially suitable for the industry design and manufacturing industry, with short life cycle and a small variety of products. Its original products can be used as product design verification, functional testing and auxiliary cookware development, so it can quickly assist the product to open the wrong risk of low opening mold production, effectively shortening the opening time and Reduce costs and make products more competitive. X However, for the development of rapid prototyping technology in the new generation, Rp is no longer just a synonym for rapid prototyping, but a new term, called rapid production or rapid manufacturing. So how to get rid of the previous prototype that is only limited to wearing = appearance reference, and can quickly produce functional elements ^ unctional Parts) 'such as embedded (jnsert), combination (Assembly), and with multiple materials (Multi Material) It is an important research topic for rapid prototyping technology. ‘, P fast application is all-encompassing, and currently not only industrial applications, but also to the medical, art, geographic information and humanities. Applying the most mature industrial prototypes and models as an example, it is generally applicable to the Concept Model for the verification of Hanometers. As for the models, the models with high strength and hardness are only suitable for the number of turns. However, if the cost of a rapid prototyping machine is 4 [51 1358358 only for the application of this concept prototype, its applicability is bound to be limited. Furthermore, due to the shorter life cycle of products in the market in recent years, the rapid development of business technology has shortened the time course of product development to improve product competitiveness and market share. Therefore, in addition to providing fast and accurate shape samples, rapid prototyping technology must be functional in order to make rapid prototyping technology more widely used. Please refer to the first figure. The principle of rapid prototyping is that when the preliminary design is completed, the computer is used for computer-aided design (3D CAD). Traditionally, it is manually or mechanically based on the two-dimensional processing map. Prototype system, this method requires further design of fixtures or molds. The whole process often takes a lot of manpower and material resources. If the prototypes produced show errors, the whole process is bound to come back. If you use rapid prototyping, I will use the 3D graphics on 3D CAD and the 2D plane of the layer to be the father. The result of the intersection is a stack of two-dimensional geometric data, each of which represents the cross section of the two-dimensional solid figure. Next, the computer takes out the bottommost piece 4 of the picture type, as the computer positioning control, transmits the energy source and the original material to the working surface, and adds the raw material to the position indicated by the geometric figure. According to this procedure, the bottom is From the end to the top, the raw materials are filled and bonded one by one, and the completed three-dimensional prototype can be taken out after completion. In theory, when a layer of two-dimensional sheets is thin, the stereoscopic geometry created by the stereo prototype and the original computer will be exactly the same. The rapid prototyping technique can also be called Material Increase Mamifactoing or Layer Processing Technology (Layer). Manufacturing Technology) ' or 自由 Free Freeform Fabrication, because its processing method is different from traditional processing methods, such as lathes, milling machines, grinding machines, planers, etc., rapid prototyping is the use of materials Layers are added and stacked. In general, rapid prototyping can be divided into three categories according to the materials used: powder, liquid resin, and solid materials, each with its own characteristics and application fields. In the aspect of solid material molding, it is generally processed by using a sheet material adhered to 5 1358358 (Gluing Sheets). From the processing principle, any material that can be made into a sheet can be used in this way, but because of energy devices and waste stripping. In addition to the limitations of workpiece positioning and other factors, most of the papers are currently used. The well-known manufacturers include Laminated Object Manufacturing (LOM) from CUBIC, and Selective Additive from Japan KIRA. And Hot Press, SAHP), currently Singapore KINRGY company also has a Zippy machine similar to LOM. Please refer to the second figure, which is a flow chart of a traditional LOM process. Generally, the typical LOM uses paper as the raw material, because the paper is made of wood • so the finished product of L〇M is very similar to the wood product. LOM is a mixed processing of Additive Method and Subtractive Method. This is the biggest difference with other rP machines, which are mostly processed by feeding. The machining process is as follows: - STEP 1: The paper advances until it covers the entire workbench. STEP2: The bed rises into contact with the paper and touches the limit switch of the z-axis to control a certain height.
STEP 3:接著同時進行兩個動作。軟體方面計算STL 檔與某一水平面之交集，以求出輪廓線。硬體方面則將 φ 熱滾筒浪壓’使紙張結合。 STEP 4 :光學透鏡將雷射光聚焦在紙張上，將紙張 切割成四邊形框，形成一個外圍（1&11)，使紙張分成加 工範圍與連續送紙之邊緣。 STEP5 :雷射依照工件外形輪廓切割，切割厚度剛 好為一張紙之厚度。 STEP 6 :外形輪廓與外圍〇^11)之間， 十字交叉形（〇0sshateh)，使廢料容易剥除。田身于」成 STEP 7 ·床台下降以利紙張前進。重stepsi〜7 至工件完成。 STEP 8 ·將整塊積層物件取下’並將廢料小心剝除 6 後取出原型工件。 關於薄片積層法方面’因材料多樣化，可製作不同 材質之原型件’因此有許多先如技術針對L〇M製程應 用材料的相關研究被提出。Klosterman等人以陶竞和複 合材料為研究對象，製作異種材質之原型件。Chi等人 提出一種Curved Layer LOM以片狀金屬材料，來製作 金屬原型，擴展了 LOM的應用範圍。於製作上使用二 種方法’第一是採用雷射切割已包覆銅的不鑛鋼片（a Copper Clad Stainless Steel)’接著用不鏽鋼線予以定 位’並用重物施壓固定’放於高溫爐中進行銅焊 (Brazing )。此法因廢料早已取出，所以無廢料剝除 (Decubing )的問題，但卻不適用於倒勾之幾何，因倒 勾之造型無法給予支撐’故支撐的問題仍存在其中。第 二種方法則與目前LOM類似，先黏（B〇nding)再切 (Cutting )，用夾具將最上層材料固定，再施以點焊 (Spot Weld)予以結合’最後利用雷射切割最上一層。 此法的缺點是不但在切割時易影響下一層且廢料^除 不易。Obikawa'Bryden 等人與 Lone Peak Engineering Inc 公司也接續以金屬材料進行積層，利用疊層方式再配合 % 腦數值控制（Computer Numerical Control CNC")機且 遣行2D㈣切削方式，製作金屬工件及模具 上述這些先前技術皆為製作具功能性的元件而採 用高強度材料，但卻使得廢料剝除的問題更加困難。因 ，台灣專利公告第 438676，438677，464612，590881 魏發展快速原型-層狀成形方法之線上撥料製程，提出架 %S(Bri(ige)建構法可線上撥除大部分的廢料，並製作 出金屬工件，以及進一步所發展出的新式線上撥料積層 决，配合所提出的，入件製作法則，進行嵌入件製作。 理論上，任何薄片材料都可使用在薄片積層法的快 咦原型系統内，如紙、塑膠、金屬、複合材料和陶瓷等， 積層法因製程之限制，僅能製作單―材質的原型 綜合以上所述，茲將薄片積 生的問題整理如下： 積収和目4技術所產 1'傳統L〇M無法製作多；M·皙η 44·止丨、 品，僅能製作單—材質的原型卫件。貝（不冋材枓）的成 除因2難的 ，出來。以先切後黏的方式堆i ϊ件將難以 作完成前將廢料剝除，但卻會有¥ ^ =件製 且需發展支撐。日f ί積疋位$差的問題STEP 3: Then two actions are performed simultaneously. The software calculates the intersection of the STL file and a horizontal plane to find the contour. On the hard side, the φ heat roller pressure is used to bond the paper. STEP 4: The optical lens focuses the laser light on the paper and cuts the paper into a quadrilateral frame to form a periphery (1&11), which divides the paper into the processing range and the edge of the continuous paper feed. STEP5: The laser is cut according to the contour of the workpiece, and the cutting thickness is just the thickness of a piece of paper. STEP 6: Between the outline and the outer edge 〇^11), the cross shape (〇0sshateh) makes the waste easy to strip. Tian Shen is in STEP 7 · The bed is lowered to facilitate paper advancement. Heavy stepsi ~ 7 to the completion of the workpiece. STEP 8 • Remove the entire laminated object and carefully strip the waste 6 and remove the prototype workpiece. Regarding the laminar lamination method, 'prototypes of different materials can be produced due to various materials'. Therefore, many related researches on the L〇M process materials have been proposed. Klosterman et al. used Tao Jing and composite materials as research objects to make prototypes of different materials. Chi et al. proposed a Curved Layer LOM to produce metal prototypes from sheet metal materials, extending the range of LOM applications. Two methods are used in the production. The first is to use a laser to cut copper coated copper (a Copper Clad Stainless Steel) and then use stainless steel wire to position it and press it with heavy weight to place it in a high temperature furnace. Brazing is performed in the middle. This method has long been taken out of the waste, so there is no problem of decubing, but it does not apply to the geometry of the barb. Because the shape of the barb cannot be supported, the problem of support still exists. The second method is similar to the current LOM, first bonding (B〇nding) and then cutting (cutting), fixing the uppermost material with a clamp, and applying spot weld (Spot Weld) to combine 'finally using the laser to cut the upper layer. . The disadvantage of this method is that it not only affects the next layer when cutting, but also eliminates the waste. Obikawa'Bryden et al. and Lone Peak Engineering Inc also successively laminated with metal materials, using the lamination method and the Computer Numerical Control CNC" and the 2D (four) cutting method to make metal workpieces and molds. These prior art techniques used high strength materials for making functional components, but made the problem of scrap stripping more difficult. Because, Taiwan Patent Notice No. 438676, 438677, 464612, 590881 Wei developed the rapid prototyping-layer forming method for the online material-distribution process, and proposed the rack %S (Bri (ige) construction method to remove most of the waste on the line and make it out Metal workpieces, as well as further development of new type of online material stacking, in conjunction with the proposed, in-piece manufacturing rules, for insert fabrication. In theory, any sheet material can be used in the rapid stacking prototype system of the sheet stacking method. Such as paper, plastic, metal, composite materials and ceramics, etc., due to the limitations of the process, only the single-material prototype can be produced as described above. The problem of sheet accumulation is as follows: Accumulation and mesh 4 technology The 1' traditional L〇M can't be produced much; M·皙η 44· 丨 丨, product, can only make a single-material prototype. The shell (not 冋 枓) is divided into 2 difficult, come out It is difficult to remove the scrap before the completion of the first step and then stick, but there will be ¥ ^ = part system and need to develop support. The problem of the day f ί accumulation $

The function operation 'but the two objects have no area on the intersection Ϊ 'so the matrix does not need to change 'and then take' and the F object to calculate, , the object area is calculated by the Boolean function, resulting in intersection, and D object 18 1358358 The area is larger than the F object area, and there is no other object behind the D object in the original [B, D] matrix, so [B, D] and [B, F] can be combined, and the F object can be placed behind the D object. The new matrix can be rewritten into [B, D, F], and the matrix is transformed into [B, D, F], [A, C, E], [A, G] three groups. Matrix. Finally, the E and F objects are finally compared. The E and F objects are calculated by the Boolean function, and there is no intersection. Therefore, the original matrix remains unchanged [B, D, F], [A, C , E], [A, G], this matrix is the final group and hierarchical relationship between all objects. After obtaining the material, group and hierarchical relationship between the objects, the objects can be in and out of the material type and 2D contour. The two levels of the hierarchy are defined. Therefore, the objects in the section of the slice can be represented as shown by Mijk: M: is the material type code (A, B, C, D..., Each material type) i: is the first-level ordinal position, 1, 2, 3..., the number of the group number of the level in the digital table. J: the second-order ordinal position, 1, 2, 3..., the digital table The number of groups in the hierarchy. k: is the third-order ordinal position, the number of groups in the level of 1, 2, 3... number table. Μ is the code of the type of the sheet of processed objects, with A, B, C ... and the symbol table, and the subscript symbols i, jk, etc., are the hierarchical ordinal positions of the processed objects in the processing layer, the first level of the i table, the second level of j, the third level of k, and so on. . The 1, 2, 3, 4 digits of the hierarchical ordinal number indicate the number of objects in this hierarchy, which can also be expressed as the group number of the object in this hierarchy, and 0 indicates that the hierarchy does not exist. Therefore, the matrix [A, C, E], [A, G], [B, D, F] of the hierarchical group relationship between the objects obtained by the foregoing examples can be rewritten as follows according to the definition of the object, wherein [A, C, E], [A, G] row matrix, with A object as the first, is the first group, and the first level unique object of the first group of A objects is represented by A10〇, C and G are the first group The two objects in the second level are denoted by 〇 G and G12 分别 respectively, and the Ειη object is a third level object and has a direct upper and lower level relationship with the object 19 1358358 pieces cu. Similarly, the row matrix [B, D, F ] 'Objects B200, D210, F211 are the first level, second level and third level objects in another group respectively, so the relationship between each level and group of each object can be as shown in the sixth figure. After the definition of the object, the relationship between the various materials and the level of the objects shown in the sixth figure, the object definition of the fifth figure can be as shown in the seventh figure, the processing layer has three levels, seven kinds of material objects, therefore, A The trapezoids with B are two kinds of sheets, and are the outermost level objects, which can be written as A1()0, B200 and represent respectively, and three Shapes, elliptical objects and vine-shaped objects are the same as the second level 'each with Cn〇, Gi20 and D210, and the round and square objects are the last third level, which are not shown by Εηι and F211 respectively. After the definition of the material type of each object in the layer and the hierarchical number of the contours, then the order of processing is determined. The processing conditions of the sliced objects in several different conditions will be discussed later and further explained. According to an embodiment of the present invention, when the obtained objects are defined as a single group and different levels, as shown in the eighth figure, there are three objects in the processing layer, which are squares, triangles, and circles, and the like. The group objects are sequentially coated into the same group, the circle is covered by a triangle, and the triangle is covered by a square, according to the species cutting method and the area of the object algorithm. The group has three levels, according to the foregoing The object classification definition can be expressed by A 100, Bn 〇, Cm for the processing points required for the three objects. The order of processing the objects can be expressed as shown in the ninth figure. When the object is the same material as the circle, as shown in the tenth figure, the circular object can be rewritten as Ai!i, and the order of the object processing is re-processed. Although the two objects have the same material, they are in the same Groups and different levels can not simplify the processing procedure, so it is still necessary to carry out the processing of each pass. The processing steps of the object processing steps are as shown in the eleventh figure, and the A丨Q〇, Bu〇, Cu丨 must still be performed in the order of 20 Three sets of processing are performed. According to another embodiment of the present invention, when the group 'different levels are obtained. As shown in the twelfth figure, the sum = the total has two groups and two levels, according to 4: The classification of objects can be divided into triangles, circles, and diamonds. The following two processing sequences can be obtained from the following two processing layers: BG, All, D2Q, c21, and Zhengyang. Ways to plan. α This object is 迢 rod, and the upper 5 group is divided into the financial formula to add Ji.任—^Into the early group, according to the innermost layer, the first step in the order, and then in the subsequent processing of the other group g level of the object in sequence 2 interaction == group, each object basis The innermost priority production rule is therefore to plan the processing path of the large six groups of objects by the processing of the above-mentioned objects, as shown in the thirteenth figure J: go to 'this example can obtain the f-process path of the group f, first; Select; ten; f: level 〇 ^ object processing, then re-entry, f group can get the most steps of this object processing step 2: object processing, and finally the same as 'the second group of objects Processing S uses the innermost level of priority production rule to add plus = knife group; each ^ brother - the most level of the group in the group A „object first plus ^ method is still ^ group of the most level of the ^ object processing, to the group After the first-level Βΐΰ object processing ϋ is replaced, and the first-level D2G object is added and re-introduced, the second group object processing step is performed, so that the second can be simplified. Object processing pass, if there is the same material in the adjacent pass processing path 21 / Article, this process can be preferably selected machining path and the machining path followed by this two pass processing into a single, off can reduce processing time and material savings.

According to the third embodiment of the present invention, the Lime system can provide a process for converting the thickness of the sheet, which is t! When the slope of the contour surface of the workpiece is relatively gentle, a finer day can be used. Degree, when the slope of the contour surface of the workpiece is steep, use the different thickness of the sheet to use different thicknesses to improve the processing efficiency and to maintain a certain precision. In addition, the rapid prototyping technique using laminar material lamination processing ^ Using the S1 fixed thickness sheet material as the processing material, it is impossible to change the thickness with the change of the shape characteristics, and it is easy to lose the detailed features and the dimensional accuracy. The fourteenth figure shows the effect of the change in the thickness of the machining and the shape of the contour on the stepped error. From this, it can be seen that when the dicing process is performed, since the thickness of the dicing layer is fixed, a step error occurs in actual production. As shown in the fifteenth figure, t is the thickness of the slice, and the cusp height is a step error. In general, the step error caused by layer processing is related to the thickness of the slice and the slope of the profile of the workpiece slice. As shown in Fig. 16, this relationship can be written as the equation i = J sec 0, where δ is The stepped error ri is the thickness of the slice, and 0 is the angle between the ruled surface of the sliced face and the cloud of the layer construction direction. It can be seen from the above that the thickness ί of the general layer processing is a fixed value. Therefore, when the slope of the profile of the slice layer changes, 0 will change. Therefore, the step error 5 is also not changed, so that the workpiece is outside. Profiles also produce different error precisions in each slice. Therefore, according to an embodiment of the present invention, in order to obtain the most suitable slice thickness, if the required slice precision 5 is a fixed value, when 0 varies with the slice face slope, the desired thickness of the slice layer is obtained. When the new process sheet laminating system has n sets of sheet materials of different thicknesses, it is possible to obtain the most suitable sheet thickness without exceeding 5 layers of precision. According to this embodiment, the present invention provides a method for processing a thin layer of a variable thick layer, which comprises: (1) analyzing a layered process of a three-dimensional model, and defining at least one level of objects in each layer, the hierarchical object Having a pattern; (2) according to the vertical, the slope of the contour surface of the model, each layer should be given a thick layer, the sheet material; (3) layer by layer according to the pattern of the layer object, each specified sheet material The cutting process is performed by gluing; (4) After the cutting process and the gluing process are performed layer by layer, the laminated sheet material of the three-dimensional model is constructed. According to the method for processing a thick layer of a thick layer according to the present invention, the thin layer monthly processing system of the invention of 23 1358358 thick layer, _ , each material storage device is not stored and stored, and the material is successively used.

The support problem, and no scrap i "is therefore suitable for support (4). In addition to the embodiment according to the invention, the support material can be stored in the material storage device. According to another embodiment of the invention, the support The material can be treated by a scorpion. As shown in the seventeenth figure, the area of the section line is the material of each object, and the blank area is replaced by the water-soluble or waxy object. The choice of materials, that is, the addition of new objects, it is necessary to redefine the processing of different objects. 曰 Refer to the eighteenth figure 'the evolution of the processing layer into five objects, the four materials of 24 丄 area of the Bolin transport different 'objects The first part of the sub-category is to define the object: ί明 η ^ μ The figure is not, the twenty-first figure is the internal diagram of the hoist workpiece and the temperature ===? profile diagram.

The third group of processing paths cannot be simplified because there are no adjacent material objects in the front and back. Therefore, the first simple path is added and the work is simplified according to the principle of object processing. In the object: the road plus the way In the case that the adjacent materials are processed with the same material, the two processing paths can be combined into a single pass processing and a chemical processing step. It is known from the object processing step 4玎 shown in the twenty-third figure that a path of the purlin and the younger can be processed from five sets of passes into four groups of processing and the simplified two groups of objects are processed. The processing steps are the same. The third group of processing roads is obtained by the simplification of the 曰4J·β 4 adjacent to the former Germany as shown in the twenty-fourth figure. Step 3: Performing the object processing Layer processing. After determining the most simplified object processing, the processing step can be transferred to the computer to start layer processing.
