I am probably going to buy a RepRap 3D printer by the end of the month. I know a guy who already has one, and he has printed some test objects for me. Results below. I would use a smaller extruder nozzle for my finished products to get smaller layers and better detail.

Anyhow, I'm thinking about making objects like modular barrier sets similar to those mentioned in this article (http://www.belloflostsouls.net/2012/03/hobby-my-first-tentative-steps-into-3d.html), Jersey barriers, starship corridors, ruins, custom miniature bases like those in the image, etc. Bases could be designed with raised unit insignia, roman numerals, Greek letters, or geometric designs. The space marine is on a lambda symbol for a possible Half-Life themed squad. On the downside, the RepRap leaves a layered edge surface. On the upside, this can make a unique object where that look is a benefit, or it can be polished with acetone to make the surface smooth. I am also hoping to start using these as a basis for more intricate sculpted bases with green stuff.

So, my questions for you: What sort of objects would you want to see available? What designs, sizes and shapes would you want for bases? What would you suggest for molds and resins for mass-production once a good design has been sculpted or printed to my satisfaction? Would you be interested in e-mailing your own design files for me to print, or having me design a specific model for you? Is tere something on Thiniverse , Physibles, or some other site you want to have made? Would you suggest I set up for payments through Paypal, Bitcoin, or other services?

And no, I won't knowingly make something that violates GW, Privateer, or another company's Intellectual Property. I don't like IP laws, but I don't want to deal with lawyers. Just go buy that Leman Russ Tank (http://www.thingiverse.com/derivative:18700) from your local game shop, or scratch-build it yourself.

Those bits really put me off 3d printing, i have yet to see something thats wow, from 3d printers. Also why do you not like intellectual property laws.

1. So a rough draft sets the tone for the finished product? I bet you hate novels ;) The advantage is in production cost. Those images are just proof-of-concept, with absolutely no cleanup.
2. That's far too large a discussion for a forum. Have a link to a free e-book: http://mises.org/document/3582/Against-Intellectual-Property

I love novels but some of the finished 3d products i've seen just aren't that impressive.
On the IP book I got through the first paragraph and realised the guy is missing some factors, which actually make patents better for the free market.

Maybe you should read the chapters on patents.

The bottom line is you get what you pay for. The two printers I hear most about are the RapMan 3.2 and the MakerBot. Being as I use Alibre software, I know the most about RapMan.

The RapMan (http://www.alibre.com/3dprinters/explorerapman.asp) costs roughly $1,700 and can produce items of the following quality:

Next up the chain in this line is the 3D Touch (http://www.alibre.com/3dprinters/explore-3dt.asp), which costs $4,000 and produces the following:

Note the scale difference between the two images.

Both printers probably cost more than the average hobbyist gamer would be willing to spend. For myself, if I were really jazzed to buy one, I'd probably go for the 3D Touch.

In any event, if you're spending less than $1,000 for a 3D printer, probably you'd be better off just mocking something up out of card stock.

The Rep-Rap, even with the finest nozzle available, is totally not a machine that's ready for even small-scale production runs. It's really meant for prototyping. What you've gotten from your friend is close to the best that it is possible to get from that machine.

You might be able to get a prototype done on it, then clean it up (heavily) with sanding paper, and then make molds and pour the bits in resin.

Indeed. I was planning on using it to create the foundation for something to be improved with a file and green stuff for casting. And I know that I'm not likely to make a lot with gaming supplies, so it would primarily be a way to get back into drafting. I had to abandon my drafting career when the markets crashed, and I have been stuck in a hellhole of a call center for almost 3 years. I just want to be able to use my tools for something fun on the side.

Update: The Prusa Mendel I'm planning to buy now was demonstrated at a 0.1mm layer height, and can be set at a 0.05mm layer height.

Now that's qulity! I didn't even know about that machine, thanks for putting it on my radar!

This is another run, 0.2mm layer height. The machine is new, and still being calibrated. The tiles are glass 3/8" mosaic tiles. The photo is with my cell phone, so it is not in good focus. It has the same stratification as the previous set, but it's far less pronounced with just that change. I plan to use liquid green stuff to get a smooth surface, and use these as masters to mold in resin.
