講解兩種常用的手板快速成型方法
來(lái)源：http://www.hzbfpg.cn作者：山東嘉瑞杰機(jī)械科技有限公司發(fā)布時(shí)間：2022-10-22
手板制作是在不開(kāi)模的情況下驗(yàn)證產(chǎn)品的可行性。手板一般樣本量小，生產(chǎn)周期短，人力物力浪費(fèi)少，產(chǎn)品設(shè)計(jì)缺陷發(fā)現(xiàn)和改進(jìn)速度快，為產(chǎn)品完成和量產(chǎn)打下堅(jiān)實(shí)的基礎(chǔ)。下面山東快速成型廠(chǎng)家來(lái)講講講解兩種常用的手板快速成型方法。
Prototype production is to verify the feasibility of the product without opening the mold. Generally, the sample size of the prototype is small, the production cycle is short, the manpower and material resources are wasted less, and the product design defects are found and improved quickly, laying a solid foundation for product completion and mass production. Next, Shandong rapid prototyping manufacturers will talk about two commonly used prototype rapid prototyping methods.
1.激光快速成型（SLA/SLS)
1. Laser rapid prototyping (SLA/SLS)
激光快速成型由原材料的不同分為SLA和SLS兩種。
Laser rapid prototyping can be divided into SLA and SLS according to different raw materials.
SLA是利用3D雕刻原理的工藝，也稱(chēng)為光敏樹(shù)脂的選擇性固化，是早的快速成型技術(shù)。過(guò)程如下：當(dāng)樹(shù)脂槽充滿(mǎn)波浪狀光敏樹(shù)脂時(shí)，它會(huì)在紫外激光束的照射下迅速固化。在成型過(guò)程開(kāi)始時(shí)，可升降工作臺(tái)處于波前下一個(gè)橫截面層的高度。
SLA is a process based on 3D engraving principle, also known as selective curing of photosensitive resin. It is an early rapid prototyping technology. The process is as follows: When the resin tank is filled with wavy photosensitive resin, it will rapidly solidify under the irradiation of ultraviolet laser beam. At the beginning of the forming process, the height of the elevating table at the next cross section layer under the wave front.
聚焦的激光束在計(jì)算機(jī)控制下，按照以下要求沿液面掃描：用于在掃描區(qū)域創(chuàng)建樹(shù)脂的橫截面輪廓固化以獲得具有橫截面輪廓的樹(shù)脂片。
The focused laser beam, under the control of a computer, scans along the liquid surface in accordance with the following requirements: it is used to create a cross sectional profile of the resin in the scanning area and cure it to obtain a resin sheet with a cross sectional profile.
然后工作臺(tái)降低薄膜層的高度，固化后的樹(shù)脂薄膜上覆蓋一層新的液態(tài)樹(shù)脂，用于第二層激光掃描固化，新固化的層就是之前牢固粘附的A層層。重復(fù)此操作，直到形成整個(gè)產(chǎn)品。后，完成清潔、支撐、二次固化和表面處理。
Then the workbench lowers the height of the film layer, and the cured resin film is covered with a new layer of liquid resin for the second layer of laser scanning curing. The newly solidified layer is the previously firmly adhered layer A. Repeat this operation until the whole product is formed. After that, cleaning, support, secondary curing and surface treatment are completed.
光敏樹(shù)脂選擇性固化快速成型技術(shù)適用于中小型工件的生產(chǎn)，可直接獲得樹(shù)脂或類(lèi)似工程塑料制品。SLA快速成型具有優(yōu)異的表面質(zhì)量、高系統(tǒng)分辨率和高成型精度。
The selective curing rapid prototyping technology of photosensitive resin is applicable to the production of small and medium-sized workpieces, which can directly obtain resin or similar engineering plastic products. SLA rapid prototyping has excellent surface quality, high system resolution and high molding accuracy.
SLS的加工方法與SLA技術(shù)類(lèi)似，只是用粉體原料代替波態(tài)光敏聚合物，對(duì)粉體材料施加恒定的掃描速度和能量。在成型過(guò)程中，激光參數(shù)、粉末特性、燒結(jié)氣氛是影響燒結(jié)質(zhì)量的重要因素。
The processing method of SLS is similar to SLA technology, except that powder raw materials are used instead of wave state photosensitive polymers to apply constant scanning speed and energy to the powder materials. In the forming process, laser parameters, powder characteristics and sintering atmosphere are important factors affecting the sintering quality.
SLS快速成型可以創(chuàng)建困難的手板，并且可以使用多種原材料，例如大多數(shù)工程塑料、蠟、金屬和陶瓷。零件的構(gòu)建速度快，無(wú)需對(duì)零件進(jìn)行后期校正。沒(méi)有設(shè)計(jì)和施工支持。
SLS rapid prototyping can create difficult handboards, and can use a variety of raw materials, such as most engineering plastics, waxes, metals, and ceramics. The construction of parts is fast, and no post correction is required for parts. No design and construction support.
2、CNC快速成型
2. CNC rapid prototyping
CNC在機(jī)械加工行業(yè)應(yīng)用廣泛，技術(shù)相對(duì)成熟。在手板的加工中，效果和精度都非常好，所以我們要考慮如何加工手板。
CNC is widely used in the machining industry, and its technology is relatively mature. In the processing of the hand board, the effect and precision are very good, so we should first consider how to process the hand board.
對(duì)于塑料加工材料，ABS灰白色/黑色/透明；PMMA亞克力（無(wú)色透明/有色透明/珍珠光澤/壓花）電木（不透明深色、棕色/黑色）PC、PA尼龍、PA+玻璃纖維鋼（POM)包括)白色/黑色PP乳白色；金屬材料包括鋁合金、銅（紫紅色光澤）、不銹鋼、鈦合金、鎂合金、鋅合金。
For plastic processing materials, ABS is off white/black/transparent; PMMA acrylic (colorless transparent/colored transparent/pearl luster/embossed) bakelite (opaque dark, brown/black) PC, PA nylon, PA+glass fiber reinforced plastic (POM) including) white/black PP milky white; Metal materials include aluminum alloy, copper (purple luster), stainless steel, titanium alloy, magnesium alloy and zinc alloy.
CNC手板機(jī)的表面處理方法多種多樣，包括打磨、噴灰、噴漆、拋光、絲網(wǎng)印刷、電鍍、氧化、激光雕刻、釀造和UV，其效果甚可以同模具出產(chǎn)出來(lái)的產(chǎn)品比美。觀在外，裝配，功能驗(yàn)證上，都可以達(dá)到客戶(hù)規(guī)劃驗(yàn)證目的，CNC能做出一個(gè)能實(shí)在反映您規(guī)劃目的工件。
The surface treatment methods of CNC hand lathes are various, including polishing, spraying, painting, polishing, screen printing, electroplating, oxidation, laser engraving, brewing and UV, and their effects can even compare with those of products produced by molds. Outside, assembly and functional verification can achieve the purpose of customer planning verification. CNC can create a piece that can truly reflect your planning purpose.
