In twenty-first Century, many new fun things appear in people's field of vision, there are a lot of breaking the traditional thought of people, there are also some upgrade in the traditional things, the reform brought. For example, recently received more and more attention to the 3D printing technology. Is actually on the basis of traditional print, from 2D 3D, and joined the UV LED curing technology, before making the fantasy into reality.

不同形状和大小、角度、弯曲、边缘、凹凸情况的三维部件UVLED光固化时，需要有光投射到所有的表面上，且应有可靠和足够的能量。一般灯具由灯管和反光罩组成，反光罩用于聚集光束定向投射到器物上，反光罩一般为椭圆形或抛物线状的。使用椭圆形灯罩。灯管置于椭圆的第一焦点上，灯光则在第二焦点上聚焦形成狭窄的高幅度的光束。但由于光的发散，偏离此点后，辐射度迅速减低。使用抛物线灯罩，在较宽的范围内均可得到平行紫外光束，但是辐照度低并可在三维物体上增加阴影。

Three components of UVLED light curing in different shapes and sizes, angles, bending, edge, uneven situation when needed light projected on the surface of all, and should be a reliable and sufficient energy. The general lamp is composed of lamp tube and reflector, reflector beam directed onto to gather the utensils, the reflecting cover is generally elliptic or parabolic. Using an oval shade. One focus of the ellipse in the lamp, lights in the second focus focus on forming a narrow beam of high amplitude. But due to the light divergence, from this point, the rapid reduction of radiation. Using a parabolic lampshade, in a wide range can be parallel beam of ultraviolet light, but low irradiance and increase in the shadow on a 3D object.

因单体刺激性及对某些材质接着性，水性UVLED发展亦指日可待，目前欧洲纸上光，水性UVLED油墨，家具喷涂发展较快。主要为客户需改机器设备，干燥速度较原有纯UVLED慢，但在3D家具，喷墨油墨上大有可为。

Because monomer stimulation and on some material then, water and its development also just around the corner, at present Europe paper glazing, water of UVLED ink, furniture coating rapid development. The main customers need to change equipment, dry faster than the original pure UVLED slow, but in the 3D inkjet ink on furniture, have a brilliant future.

为了使整个表面充分固化，需要采取一些措施：一是改善椭圆形灯罩形状，变化光的焦点，使它离灯面更远。使聚焦面更宽，虽然这样会减少高辐照的峰值，但可以使光的强度比较均匀，在离灯较远的地方也可以得到足够的辐照，同时又保持了聚集和发散光的优点。减少阴影出现;第二项措施是优化配方;涂料的光谱吸收要与灯的光发射光谱相匹配;第三是优化工业条件，紫外光投射到物体的能量要与加工速度相匹配;涂料光敏性及涂层的厚度要优化，在较大光强度变化范围内都能使表面涂料测底固化。

In order to make the whole surface fully solidified, some measures are needed: first, to improve the shape of the oval shaped lamp shade, and change the focus of the light, so that it can be farther from the surface of the lamp. The focusing surface more wide, although this will reduce the peak of high radiation, but can make light intensity is relatively uniform, in the place which is far away from the lamp can also obtain sufficient irradiation, while maintaining the advantages of aggregation and astigmatism. To reduce the appearance of shadow; the second measure is to optimize the formulation; coatings absorption to and the light emission spectrum matches; the third is optimizing the industrial conditions, the ultraviolet light projected onto the object's energy to match the processing speed; photosensitive coating and coating thickness to optimize and in than the variation range of the optical intensity can be measured at the end of the curing surface coating.

当然对于3D固化装置也有特殊要求。要根据物体大小和形状，物体是垂直还是水平的，能否通过旋转使潜在的阴影部位得到照射等实际情况设计生产线。为了进行UVLED光固化，能力要求与固化速度的调节等目的，将灯源装在机器人上是一个重要的方法。采用机器人有很多优点，许多固定灯源不能照射到的部分都可得到有效的照射。如前所述，以玻璃钢为车身的涂料耐候性高出许多年。

Of course, there are special requirements for the 3D curing device. According to the size and shape of the object, the object is vertical or horizontal, whether by rotation. The shadow of potential sites get actual irradiation production line design. In order to carry out the UVLED light curing, regulation ability requirements and curing speed, the light source mounted on the robot is one of the important methods. The robot has many advantages, many fixed light source can not shine to the part can be effectively irradiation. As mentioned before, using glass steel as weatherability body up for many years.

显然3D打印技术只是处于一个刚刚起步的阶段。人们还没有开始从这项技术中获利，但是人们已经开始意识到了这项技术的前景，3D打印经过这几年的迅速发展，也开始有了一些技术上的突破。不仅仅停留在最开始的时候的起步阶段。

Obviously, 3D printing technology is in a fledgling stage. People do not start to make a profit from this technology, but people are beginning to realize that the prospect of this technology, 3D printing rapidly after several years of development, but also the beginning of a number of technological breakthroughs. The initial stage not only in the beginning.
