adding a new way to do the 3D printer Frame The first drawing is how the laser or plasma cut the frame File:2nd draft.FCStd
The second one is for how to make the pieces which has been cut via leaser machine bended via a normal bending machine and how it will be assembled

Wow, that is interesting and useful. If you have a metal brake, though.
I added the picture at http://opensourceecology.org/wiki/Ahmed_Log
Please test how this works in terms of time when you build this.
My prediction is that the amount of time it takes for alignment will not be easy. It is possible, but it will take some time to align everything to the under 1 mm that is required to make a nice frame. But I'd like to see your results, so please take detailed notes on the time:
- Cutting
- Marking bend lines
- Bending
- Aligning and laying up for welding
- Welding
Using the existing way, it took me 2:30 hours to make 9 frames starting from the cut metal, using magnets to hold the frames together, including layup, welding, and painting. For welding, all I did was tack each side at 4 points. This was for the 13" frames.
I am guessing that it will take you that amount of time to do steps 2-5 for a single frame. But if you do this and take the data point, that would be very useful - maybe you can do it much faster than I think it will take. If we are to consider this route for the Saudi build, the time it takes you to make these frames must be very low. For an 8 hour build - you would need to build 12 frames per hour. Do you think that would be possible?
Using our route, welding takes 5 minutes per frame, so a single welder person with an assistant doing layup can do the entire frame set in the 8 hours. In the workflow that we want to use - we probably want 4 welders so all the frames are done in 2 hours. This is when we do the build with the frames being done during the workshop - not premade before the workshop.
Also, when you nest the metal, that is a great idea. But because you need 2 of the large structures per frame, you will not be using the inside cutouts from the second large structure. So there is a bit of waste, maybe 30% metal waste.
