I'm going to try and keep this as simple (basic) as possible. I envision a build plate that is in a carrier so it can easily be removed when the print is done. Also the resin tank needs to be removable for easy cleaning. Then there is the matter of preventing the cured resin from sticking to the bottom of the tank. I think some combination of non stick surface and mechanical movement. As you can see it will be easy to get very complex. I'll have to resist the temptation to over engineer. I'm working on a more detailed design mock up that I'll have ready in a few days.
My goal is to create a 3D printer that can be built with readily available, easily fabricated and affordable components.
I hear you thinking..."He must be MAD! It just can't be done!"
Only time will tell.... Cue the manical laughter.

As you can see it's really not that complicated (mechanically at least). For this project I'm going to try to stick with 2 principles. Keep it simple and make it cheap! My intention is to build a functional 3d printer within my almost non-existent budget. Later, if successful and as finances allow, I can upgrade components to achieve higher precision.
I can break this project down into 3 parts:
I'm confident that I can build the hardware portion of the printer. It's actually much less complex than the inkjet/powder printer. In fact, I'm going to harvest much of what I need from that progect. I'm working on a design sketch which i'll post soon.
The software... well, I would love to be able to purchase comercial RP software (Magics 15) but there is no way that will ever happen. I think it's considered the gold standard because you need a pile of gold to buy it! It seems that any software that does everything I'll need (including generating support structures) falls into the catagory of "If you have to ask you can't afford it". Since I don't have access to a pile of gold, I'm going to make due with what I can afford (free) and what I already have (Powerpoint). I'll have to make due with manually adding support structures. I'm really hoping that the open source community will develop something for that.
Lastly, the chemistry. I'll worry about that after I get the hardware working. I see this as being alot like the ink/toner of 2d printers. The real money is in the consumables.
Now to sketch up some designs and start collecting materials.

While I'm done with the powder based concept I have not lost my interest in developing an affordable 3d printer. And when I say affordable I mean one that I can afford (Meaning as cheep as possible). I'm really excited by some of the work being done on DLP 3d printers and have decided to shift directions and pursue this technology.
Check out what Junior Veloso is doing with his DLP printer!
If that doesn't get you fired up then youre reading the wrong blog!
There's also an open source project by TJ Snyman that's in the development stage
The good news is that I can cannibalize the powder printer for the electronics and mechanical stuff. Now to start gathering materials and start planning.
