對於各類產品的精（jīng）密要求越（yuè）來越嚴格，很（hěn）多（duō）企業都是先做個模型參考，而東莞手板廠就能為這些企業製造相應的模型，磅他們自己檢測出相應的產品是否達到（dào）他（tā）們自己的要求。而東莞手板廠對手板的加工方法大致是分為兩種（zhǒng）：

（1）、激光快速成型：激光快速成型由原材（cái）料的不（bú）同分為SLA和（hé）SLS兩種。

SLA是采用立體雕刻手法進行（háng）加工的手（shǒu）藝，是較早期出現（xiàn）的（de）快速成型技術之一。

而激光快速成型得製造手藝過程（chéng）是：

①在樹脂槽中盛滿液態光敏樹脂，它在紫外激（jī）光束的照射下會快速固化。成型過程開始時（shí），可（kě）升（shēng）降的（de）工作台處於液麵下一個截麵層厚的高度，聚焦後的激光束，在計算機（jī）的控製（zhì）下，按照截麵輪廓的要求，沿液麵進行掃描，使被掃描區域的樹脂固（gù）化，從而得到該（gāi）截麵輪（lún）廓的樹脂（zhī）薄片。

②工作台下降（jiàng）一層薄片的高度（dù），以固化的樹脂薄片就被一（yī）層新的液態（tài）樹脂（zhī）所覆（fù）蓋（gài），以便進（jìn）行第二（èr）層激光掃描固化，新固化的一層牢粘結在前一層上，如此重複，直到整（zhěng）個產品成型完畢。

③進行清洗、去處支撐（chēng）、二次周化以及表麵光潔處理（lǐ）等。

光（guāng）敏樹脂選擇性固化快速成型技（jì）術適合於製作中小形工件，能直接得到樹脂或類似工程塑料的產品。

2、CNC快速（sù）成型

越來越多東莞手板廠（chǎng）在應用CNC機，技而且術相對成熟。用於清溪手板廠加（jiā）工效果（guǒ）以（yǐ）及精（jīng）度也非常好，為（wéi）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.
