P3P r3 Beta
Description
A powder-based 3D printer.
Build area: 15.25"L x 8.8"W x 6.6"D
Based on a Lexmark z715 inkjet printer.
This is a revision of a project started at University of Washington, under Prof. Mark Ganter, in the Solheim RP Lab.

I've run in to some problems with the rail alignment. I made no allowance for adjustment, and the thing is way out of whack.
And then I decided to shack up with a wonderful lady, and so the domestic arrangements have me otherwise occupied.
Is someone still working on this? Would be great! If so, please keep the thingiverse entry somewhat up to date...
I think I'm the only one keeping contact. What's the progress? Fogassa's fed up. Overworked and unappreciated. That's not true but I think he feels that way.
LOL, ya, computer models are considered perfect....but we know the real world doesn't work that way, if only :-P
We would all still love some pics of your progress, even if it's not a finished prototype.
It's now Sept. What's your progress? Probably got tied up with things huh?

It would be very interesting to use this as the basis for a SIS system, one of the more recent developments in 3D printing technologies. It has elements of 3DP (like Z-Corp) and SLS (like EOS). SIS sprays a mask of sintering inhibiting 'ink'. Then, an infra red radiator heats up the entire layer at once. This will allow you to make such a device without requiring a laser and the expensive optics and safety problems that come with it. Also, the benefit (as compared to FDM(tm) and FFF of not needing support structures is of course an important one).

Added current Bill of Materials.
Left out fasteners, wiring, and electrical connectors.
The part number for HSI is proprietary, but I made sure that it is "open", so it is available to everyone.
It looks like Lin Engineering no longer carries the Trinamic controllers, but an Arduino-based controller might be a better choice anyway.
The prices for the waterjet aluminum parts are kind of high, because I made a revision and had to get some parts recut, and was then subject to $100 minimum o
rder, when the original order was $202.
And I just realized that I left off the motor and tubing for the roller, and the pulley I spec'ed doesn't fit on the motor anyway, so I had to make an adapter bushing, which is also not in the BOM.
Yeah, I guess this really is an alpha revision. :-[
I'm pro diy 3d printer but he's jumped the gun on this release, he doesn't seem to have anything but a basic idea and a desire. I can't wait to see the build as I'll be contributing where I can.
By the way, it seems impossible to get a membership approved in Yahoo's 3d printing group even after sending an e-mail to the moderator. What's up with that...makes me want to keep all my experience to myself.
For now I'll give KevinH 1 star for getting the ball rolling.
More than just a basic idea.
It's a complete mechanical design.
The carriage frame is assembled, and chassis parts are on order (maybe shipping today?).
I have all the major electrical components except the power supply. For ease of programming, I'm using Trinamic's TMCM-310 stepper controller.
Kevin, this is super work. Especially the use of existing printer guts. What sort of resin/bonding agent do you use? I've always thought it would be amazing to see a powder printer that used some easily available consumables, like flour and water, or something similar. I'm at the UW too; We should meet up! I'd love to see the prototype
It's not all done yet. I am ordering the parts for the chassis on Friday (payday). Should be about 2 weeks to arrive, so I'll probably be able to start assembling the box around August 7 or so.
This is an exciting development! There are now three 3D printers on Thingiverse, assuming someone's remembered to get the RepRap designs in here...

This is wholly too awesome. I am really amped to wrap my brain around this and produce a working unit. More than happy to share my results. Carry on with the great work!
