    下面是如何使光固化3d打印机。它仍然是一个位的一个进展中的工作,但到目前为止,这是相当不错的了。这主要是一个实验,开始作为一个三角洲的机器人光固化机,但最终一个更传统的直角光固化机。
    Here is how to make a Stereolithography 3D Printer. It is still a bit of a work in progress but so far it is working pretty well. This is mainly an experiment which started as a Delta Robot Stereolithography Printer but ended as a more traditional Cartesian Stereolithography Printer.


    光固化(SLA光固化设备SL或)是一种添加剂制造过程中使用了一大桶液体UV固化光敏聚合物“树脂”和UV激光在时间建立零件层。每一层上,在激光束跟踪的部分的横截面图案的表面上的液态树脂。接触到的紫外线激光固化,固化的树脂跟踪模式,并坚持它下面的层。 我一直想一个3d打印机了,而现在,有一些非常合理的价格包可以像MakerBot,Ultimaker和的Reprap项目。我刚刚买了一个工具包,并开始打印的东西,但在的时候,我还没有看到从那些伟大的分辨率或打印质量。我开始四处寻找其他3D印刷技术,发现SLA提出了一些惊人的打印质量,所以我决定尝试做我自己。自从我开始这一段时间回这些项目已经走过了漫长的道路,现在他们可以做一些漂亮的打印输出。还有人在UV树脂和DLP投影机的3d打印机崭露头角。 我决定进入这个在收尾挑战赛,因为我真的可以使用的激光切割机:-)我也有一些想法,如何重新设计这个项目,创建的激光切割机。制作工具的人,我不会介意,如果我有一个 要记住的东西是目前的市售紫外/可见光树脂成本。1公升大约是$ 200 - $ 250,ABS或PLA塑料挤出打印机约4 - 5倍以上,据我可以告诉。还有其他类型的树脂便宜,但我不知道他们如何工作,    因为我是真的不知道,如果这将是一个可行的方法创建3D对象,这是一个相当便宜,快速地设计项目。我有一个小Taig数控铣床,用于切割金属,所以自定义部件均采用废铝我已经铺设周围。你或许可以使用木材,甚至手工切割的部分,如果你是细心的。  这个项目是开放源码硬件。  
    Stereolithography (SL or SLA from Stereolithography Apparatus) is an additive manufacturing process using a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts one layer at a time. On each layer, the laser beam traces a cross-section pattern of the part onto the surface of the liquid resin. Exposure to the UV laser light cures, solidifies the pattern traced on the resin and adheres it to the layer below.

    I have wanted a 3D Printer for a while now and there are some very reasonably priced kits available like the Makerbot, Ultimaker and the RepRap project. I could have just bought a kit and started printing things but at the time I had not seen great resolution or print quality from those. I started looking around at the other 3D printing technologies and found SLA made some amazing quality prints, so I decided to try making my own. Since I started this a while back those projects have come a long way and they can make some beautiful prints now. There are also people working on a UV resin and DLP projector 3D printer which is showing promise.

    I decided to enter this in the Epilog Challenge Contest because I could really use a laser cutter :-) I also have some ideas how to redesign this project, for creation on a laser cutter. I wouldn't mind making kits for people if I had one.

    Something to keep in mind is the current cost of commercially available UV/Visible resins. 1 Liter is about $200 - $250 so compared to ABS or PLA for the plastic extrusion printers it is about 4 - 5 times more as far as I can tell. There are other types of resin that are cheaper but I do not know how well they will work.   

    Since I wasn't really sure if this was going to be a viable method of creating 3D objects, this was a fairly cheap and quickly designed project. I have a small Taig CNC Mill for cutting metal so the custom parts are made of scrap aluminum I had laying around. You can probably use wood and maybe even hand cut the parts if you are careful.
    This project is Open Source Hardware.
