對(duì)于各類產(chǎn)品的精密要求越來越嚴(yán)格，很多企業(yè)都是先做個(gè)模型參考，而東莞手板廠就能為這些企業(yè)制造相應(yīng)的模型，磅他們自己檢測(cè)出相應(yīng)的產(chǎn)品是否達(dá)到他們自己的要求。而東莞手板廠對(duì)手板的加工方法大致是分為兩種：

（1）、激光快速成型：激光快速成型由原材料的不同分為SLA和SLS兩種。

SLA是采用立體雕刻手法進(jìn)行加工的手藝，是較早期出現(xiàn)的快速成型技術(shù)之一。

而激光快速成型得制造手藝過程是：

①在樹脂槽中盛滿液態(tài)光敏樹脂，它在紫外激光束的照射下會(huì)快速固化。成型過程開始時(shí)，可升降的工作臺(tái)處于液面下一個(gè)截面層厚的高度，聚焦后的激光束，在計(jì)算機(jī)的控制下，按照截面輪廓的要求，沿液面進(jìn)行掃描，使被掃描區(qū)域的樹脂固化，從而得到該截面輪廓的樹脂薄片。

②工作臺(tái)下降一層薄片的高度，以固化的樹脂薄片就被一層新的液態(tài)樹脂所覆蓋，以便進(jìn)行第二層激光掃描固化，新固化的一層牢粘結(jié)在前一層上，如此重復(fù)，直到整個(gè)產(chǎn)品成型完畢。

③進(jìn)行清洗、去處支撐、二次周化以及表面光潔處理等。

光敏樹脂選擇性固化快速成型技術(shù)適合于制作中小形工件，能直接得到樹脂或類似工程塑料的產(chǎn)品。

2、CNC快速成型

越來越多東莞手板廠在應(yīng)用CNC機(jī)，技而且術(shù)相對(duì)成熟。用于清溪手板廠加工效果以及精度也非常好，為目前首先考慮的手板加工手段。

1, laser rapid prototyping (SLA/SLS)

Laser rapid prototyping by raw materials can be divided into different SLA and SLS two.

SLA is by using the three-dimensional carving (Stereolithography) principle of a kind of process, also called photosensitive resin selective curing, is the earliest appear a kind of rapid prototyping technology. The process is: in the resin tank filled with liquid photosensitive resin, it in the ultraviolet laser beam irradiation will fast curing. Molding process started, can lift the table in a liquid level next section thick height, focus after the laser beam, in under the control of computer, according to the requirements of the cross section profile, the liquid level scanned, make be scan area of the resin curing, thus obtains the cross section profile of the resin flake. Then, table drop a layer of wafer height, with solidified resin flake was a new layer of liquid resin covered, in order to carry on the second laser scanning curing, new curing layer firm bond in the previous layer, so repeated until the entire product after forming. The last place clean, support and secondary ZhouHua and smooth surface treatment etc.

SLS processing method and SLA technology similar, but with powder raw material replaced liquid light polymer, and with a certain scanning speed and energy effect on powder materials. In the forming process, the laser parameters and powder characteristics and sintering atmosphere is to influence the quality of sintering were important factors. SLS rapid prototyping can produce the most hard board, and can be utilized in a variety of materials, such as the vast majority of engineering plastic, wax, metal, ceramics, etc., the construction of high speed parts, no need for parts after correction, without design and structural support.

2, CNC rapid prototyping

CNC in mechanical processing industry use widely, technical relative mature. Used in qingxi plank factory processing effect and precision is also very good, as the first panel processing means.
