We decided to make a back bone for the machine out of aluminium profiles that we had lying around.
A simple compact design. Staring with two horizontal profiles which will make contact with the table to provide a steady base, two risers with a horizontal beam make a bridge over the beamer. To this bridge the building platform and Z-axis are attached.

We decided to use 2mm thick aluminium plate as a base to put the beamer on and an other 2mm thick sheet to hold the basin.

Because of the profiles we are using as the back bone, 45mm square aluminium profiles. We can really get away with this structure using no diagonal supports without losing rigidity. These profiles are really massive and a bit of an overkill for this type of machine.
What you cant see in the rendering here are all the corner pieces we used to bolt together the frame. I will put in some pictures later in the build.

Because we are going to use light sensitive materials in the end we will cover the printer with a box to keep out any light and dust.

So first of we hit a small dilemma for starting the design, how big does it all need to be? Where does what go? Etc etc. ok it took us a day or two to figure our how to determine all off this. I mean the whole build is based on this so it's rather important.

Materials/tools:
Beamer
Computer
Ruler
Tape measure
Notepad
Pencil
Cardboard
Scissors
Tape
Plain white paper
Chair

First think about your X and Y, the size of your build area. We chose about 100x100mm to start with. The build area in the Z direction is of course dependent on the length of your linear slide.
First of you will need your Beamer and your computer to project an image. Place your Beamer on a chair facing the wall. And put the Beamer on maximum magnification. Move the Beamer to the wall until your image is 100x100 and measure the distance between the lens and the wall. This is your minimum projection distance.

Now put your Beamer on its minimum magnification and move it from the wall until again your image is 100x100mm this is your maximum projection distance. This means that in the build the distance between your bottom window of your basin and the lens of your Beamer must be between these two values as your Beamer will allow for any fine tuning in this area.

To work the mirror in to this equation you measure form the heart of the lens (do not scratch or touch it) to the basin with a 90 deg angle. So if you place the mirror very close to the lens the basin must be placed higher above the Beamer. But if you place the mirror further away the basin will be placed lower but further.

Once you have figured out where to place the mirror you can determine its size. We did this by fumbling together a 45deg slope out of some cardboard and tape with some white paper on top. Placing it in front of the mirror at the desired location and turning on the beamer. Then outlining the image on maximum magnification with our pencil. Definitely you need sunglasses for this wauw that thing is bright.
We added about 2cm to this outline then took the longest side as the measure for our square mirror.
In the lab I realized I have a stack of 152x152mm glass plates, these are a bit bigger than required and will thus do fine.

我们在设计之处就会遇到一个问题,需要多大?需要做些什么?等等。好吧我们花上一天或两天来解决这个问题。我的意思是整个模型的从这步开始,是相当重要的。
材料/工具:
投影仪
电脑
尺子
卷尺
记事本
铅笔
纸板
剪刀
胶带
白纸
椅子
先想想你的X和Y(维度,即平面)——你所建立的工作区域的大小。我们选择了100x100mm开始。工作区域在Z方向上取决于线性滑轨的长度。
首先你需要用投影仪和电脑展现映像。把投影仪放在椅子上对着墙。投影仪设置成最大放大倍率。将投影仪移向墙,直到图像成100x100mm大小,测量透镜和墙壁之间的距离。这就是最小投影距离。

现在把投影仪设置在最小放大倍率并将它移动离开墙直到你的映像成100x100mm大小,这就最大的投影距离。这就是说透镜和材料池之间的距离只能在这两个距离之间微调。
将镜子置于棱镜中心和材料池之间,成90度角。所以如果你把镜子非常靠近镜头材料池必须高于投影仪。反之就应该放低。
一旦你定下来镜子的距离,你就可以确定镜子的大小。我们通过摸索,用贴上白纸的纸板和胶带做一个45度的斜面。把它放在镜子前面所需的位置,打开投影仪。然后在最大放大倍率上用铅笔对映像进行描边。你肯定需要带上太阳镜,这个过程光线很刺眼。
我们将这个描边增加了约2厘米,然后将长的那条边作为镜子的宽度。
在实验室中,我发现使用一块152x152mm玻璃板(这比需要的大一点)效果不错。
