Dear Dilek Thanks so much for your contribution! I will start extending the wiki page on Redmine with a BOM Table where we can gather the list of required components, so that we can get an overview of the expected final price of the device and so that we can all order the same components. For obvious reasons it will be easier to cooperate when we all have the same setup.

Cheers David

Hello,

I was not able to join you today although I had some info gathered for the meeting. I did some research on how to proceed with this. Read some articles and checked company websites.

WHAT I DID: I started with checking how the stepper works and what parts will be required. I checked the MLE (Maskless Exposure Systems) producers. Working principles of the DLP and DMDs which forms the DLP.

IMPORTANT PART IS HERE: Big Components that should make the stepper are DLP Software Objective column with a cooling set A stage with x y z control, aligner Light sources UV and IR light sources and sensors These are the basic parts I see. You can specialize the equipment from there. There are details into these which are of course much more complicated.

I talked to my friend at TI, he will be looking for the person to talk to about this. But I think I already found the answer...

I found a French company Microlight3d they make maskless table top stepper just like the one we are trying to build. ASML also builds production level ones

BLA BLA BLA: Because I missed the meeting I do not know much about what you discussed or decided. Can we keep notes to see how we all contribute to the project and who are missing can follow what was discussed?

I do not want to bring many new actions to your routine because we are all busy and I completely understand it.

So, I will start building a system at my work space, too.

***We will need some help on the software side for the x-y-z axis controls, sensor readout and alignment.***

I am a bit tired and might have missed some important things.

Talk to you next week.
