OK, so there's been a lot of discussion here about Rapid Prototyping services like www.3darttopart.com

So what if I create a model of a character that I think I could sell? Obviously I'm not going to pay ~$65 per copy, I would need to find an actual manufacturer to make these out of plastic or similar stuff. I'm guessing I would send them the prototype, then they would make a casting from that. I'm thinking of the collectable market here.

Anyway, I'm going to research this more - I was just wondering if anyone here had any ideas or experiences to share.

Thanks,
Boris

i'd appreciate an update on what you find out. i'd be interested in doing small production runs as well. thanks in advance.

I'd be surprised if the quality from 3DartToPart would be high grain enough to take a mold from, it's quite course.
You'd want a finer grain than that. Perhaps they do finer quality, no doubt at a higher cost - I'm not sure.

maybe you could get the arttopart model, coat it with a thin layer of wax or modeling clay to smooth out the grain and add more detail. Make the cast from the altered part. There are probably better ways to do it though.

Hello Boris,

I believe there will be a minimum order from any orient factory of about 500 units or 500 painted resin statues. And depending on the size, it might cost around $15. To $ 35. US. Per box unit. Also the more units you order the less expensive it will be. There's a few other cost like freight, shipping and customs fees. Times wise this will take 8 to 10 weeks for a factory to mould, cast and then paint them all, shipping another 4 to 6 weeks.
Someone had a good suggestion that you could add some wax to it and refine the details that way. Or if you need it sculpted maybe I could do I for you? http://www.arnettdigital.com/gq/

There are a couple of things that can be done to smooth the surface of a model. One thing we've done is use a hand cranked pasta machine and roll out thin ribbons of super sculpey that you press onto the surface of the model. This gives a thin surface that can accept fine details and can be smoothed before hardening in a low temp oven.

The other thing that we do is to apply multiple coats of Deft wood finish, it dries quick and doesn't require sanding between coats. Once the surface roughness is filled the model can be sanded smooth.

The model geometry needs to be robust enough so that these steps can be done without breaking the model.

We'll have to try the wax dipping and see how that works.

Remember that you can make a prototype that is difficult or impossible to reproduce any other way so keep that in mind if you are planning on mass producing the part.

Here's The wax formula I use to make toys patterns in to.

Enjoy.

sclptr - you've got some nice sculpts on your site.

Is the wax formula used to create a casting that will then accept additional sculpted detail?

Yes, Iíll usually start with hard clay called Chavant or wax like clay called Castilene. Then Iíll mould it in silicone, after make a wax casting of it. Which I then will use a waxer to paint and sculpt with to make the extra small shapes as needed on it. Finally and carefully scribe or carve with assorted dental tools to add all those fine micro details.
Last but not least Iíll use a solvent and tissues to polish it to perfection.

Although I do believe itís a great time and money saver to have your CGI model made with a rapid prototyping machine like the one at 3D Art To Part has. And at that price point you just canít beat it.
