Well, been a while since I have posted any updates on this project. I took it allot further than I thought I would, and spent a good 2 months or so in planning. After allot of research, I knew that Rep Rap could not create the complicated structures I needed to create my model. There was no way to support the structure while it was being built, and the time and materials it would take to find a wby stlouistechy - General
Just following over this older post here, and it sparked some interest as I am looking to accomplish much of the same results you did. I am deconstructing an old HP inkjet printer, and want to create a flat bed printer from the parts, but wasnt sure what logic to use to make the X and Y axis move and get the print heads to spray ink in the proper locations. So you were able to accomplish this usby stlouistechy - Mechanics
So I have spent the last 2 weeks now developing my idea's on a realistic approach to building my own 3D printer/Rapid Prototype machine at home. And thanks to RepRap forums, I have learned a ton from others experiences in this area. I have decided to take on the InkJet printing route since it is the most inexpensive in parts and materials if that secret recipe ingredient is found. And this weekeby stlouistechy - Powder Printing and Selective Laser Sintering
Will a powdered plastic resin work for this? If so, water is all that would to be fed from the inkjet, or bubblejet heads which appears from other member testing to be pretty easy. Here is a product I found at a local hardware store: And a little more info on these products: Thoughts? I plan on picking this up tomorrow and filling my cartridges with water for a go round.by stlouistechy - Powder Printing and Selective Laser Sintering

Following through this older post here. Has anyone made any leeway on finding a successful mix that will work with basic InkJet heads? I am considering this inkjet method for my powder bed as apposed to the UV Laser masking method that is going to run me more.by stlouistechy - Powder Printing and Selective Laser Sintering
I am most attracted to the ABS Plastics, and found this easy walk through on chemically grinding ABS plastics down to a fine powder. Looks like this may be the cheapest route, and can likely be formed from scrap ABS parts if you have access to any. While reading through patents today for anything related to SLS, I found an SLS concept printer that was file in 2005 to create the same process atby stlouistechy - Powder Printing and Selective Laser Sintering
Hey, I'm not the only one trying to pull this off after all! I would like to compare notes with your progress, perhaps we can work together to figure this one out. I have done allot of reading on how SLS works from the types of laser needed, the temperatures needed for melting points on my materials, and even possibly building my own high powered CO2 laser. It doesn't look like there is reallyby stlouistechy - Powder Printing and Selective Laser Sintering
Hello there, I have been following work on the Hydra-MMM project. Congratulations to those who helped get the concept built and running, it looks pretty incredible compared to everything else I have seen built in the home fabrication world. I am looking at building a concept Selective Laser Sintering printer, which I think has been looked at in the past by some other RepRap community members, buby stlouistechy - General
An exact replica of the suit, that is fully functional and fit to measure against my body. I will also be attempting to build on the inside the area's to run wiring for power and lights. I also have a good feeling that I may be able to fit some small servo's in it, and give it the ability to push some of the outside armor pieces. I would love to be able to mimic his scene where he does the surfacby stlouistechy - Let's design something! (I've got an idea ...)
I took a look at their listings too, and they now have some positive feedback from some of the RepRap parts they have delivered. Doesn't seem like a bad bet, but honestly, your only looking at saving around $40 depending on final bid over ordering them from a reseller like Makerbot.com. I usually only look at buying from individuals if there is a big cost savings simply because the risk of dealinby stlouistechy - General
Anyone know if more advanced Extruder's can be implemented yet on the Mendel gen 3? I would like to take on the additional tasks of finding more precise, and faster moving parts for this building project on LeBigRep...by stlouistechy - General
I am willing to bet we find a way to get the right temps to melt some forms of metal. Even the enterprise printers are offering it now, including Shapeways.com so the tech is already out there being sold as a normal option.by stlouistechy - General
OK hintss, you got me interested here. I just found his published part list for this beast at . I emailed him to get more info, and I am going to take a look at what its going to take to get this built. If we can work together and get this project going, there could be some great credit to the community for building the largest printer to date. And who knows, maybe with enough work, we can get sby stlouistechy - General
Wow, that's the first I ran across LeBigRep. That would certainly be my first choice for this project if 1) A working set of instructions were ready 2) I knew what the crap I was doin and wanted to take it on myselfby stlouistechy - General
Ahh, that must be why the rep at onlinemetals.com said they only offered buzz saw cuts. I'm really milling over the whole sheet metal option really closely here, and I still think its going to be much to much work in welds or cold adhesives and really limit the look of my smooth curves. I am willing to bet with some trial and error, I can add break away supports to these parts for Mendel to keeby stlouistechy - General
First off, thanks a ton for throwing your thoughts out here, it helps get me thinking And yes, I do have this broken into bite size pieces, and can actually break them down more than the 6 I have now. Based on the print area of the Mendel, I am fairly certain I can keep all my parts in AutoCad within its constraints. My biggest concern though, is how the quality of the prints would turn out.

Sorry for the double post, not sure where this one belongs... I have just started my likely 6 - 12 month project of fabricating an entire wearable replica of the Iron Man suit.
