RFQ micro-model kits (warning: pics)

[dymihail]

Hi all, I'm new, so please be gentle.

I have three "models" that I'd like to get prototyped, preferably CNCed in Aluminum, though modelling wax would probably work as well. I'm also open to other options if you have advice to spare (3D printing, frex).

"Models" in that each figure stands ~45mm tall and is comprised of ~30 individual parts. The models are done in Rhino and exist as .3dm files. Each "model" is ~40-50MB, so file transfer is via ftp or snail-mail CD (makes no difference to me). Here are some pics:







If this goes well, we can also talk about manufacturing if that's a capability you have. Beyond these three, there are an additional 150+ models in the works.

Would you consider SLA's or cast urethanes for multiples?

Nice models!

Man, those would be ungodly expensive for aluminum.

Could you do them as one solid part? That would be easier for a rapid prototyping machine I would think.

Cool Mechs.

We don't do it here but for prototypes I would go with 3D printing as the cheapest form.

Allum machined parts would be pretty but there are many areas that could not be machined with an average tool and then they would still have a corner radius on all inside corners.. You would pay big for that work. We can do and they would look really good so if you wish to have it quoted it would take some time and either rough dimensions or the solids files.

Thanks for the responses so far. I'm open to just about anything, except building it as a sinble part. They're very specifically designed as user-assembled models (because there's three of us that like that level of fiddliness...). Just remember that I know next to nothing about prototyping. SLA and 3D printing, to me, is the same thing. I have no idea about cast urethanes, but am willing to listen.

One really nice benefit to rapid prototyping your parts is that if nested properly you could theoreticly produce one entire assembly's parts in one setup with no bridges. (Unlike old school injection molded models that required breaking the parts off of the frame and trimming off the inevitable hangers) If done in this manner then you'd be able to just slide all the parts off the table into a box and ship it without worrying if all the parts are there.

How many prototypes do you need? If just one, I would definitely go with SLA's or some other RP service.

If you create a free account on http://www.xpress3d.com/ and upload your parts in STL format you will get immediate quotes for several different types of rapid prototype technologies.

Disclaimer: I'm not connected to the company. They do create parts for us at work once in a while though.

Thanks guys. I've spent the last several days reading up a little on the topic. And fixing a few issues in the model.

Are you only looking for prototypes, or will you want to mass produce these? Are you looking for metal mechs, or are you looking for plastic?

I build plastic injection molds. If you can afford the upfront cost, that will be the cheapest way to have your parts made for production. Expect to have your parts changed a little for easy molding, and cost effective tool building. Even then, expect your molds to cost about the same as a house. After that, you can have the parts molded for a couple of bucks per model.

If your budget will allow, I'd like to quote the tooling for you.
