Rapid prototype for lost wax method of bronze casting

With my research on new technologies I have found quite a bit of information that I am compiling for videos, articles and a book. My question is does anyone know of a company that is doing rapid prototyping of items for the lost wax method of bronze casting. It seems like this is the next step in technology and someone must be doing it. Please send me an e mail if possible at bridgette@creativesculpture.com You might also want to post here as I know others love reading posts, just like I do.

Please give contact information for the company as well as website etc if available. Thanks in advance. You guys are the greatest.

Re: Rapid prototype for lost wax method of bronze casting

I was under the impression that there are generous number of RP carving/laminating materials that can simply be burned out - so, obviously no wax - but the same principle. Invest a form - burn it out - make cast of void.

Re: Rapid prototype for lost wax method of bronze casting

On a smaller scale - jewelry companies use it for metal casting / prototyping. I saw it at a manufacturing engineering tradeshow - ie. WESTEC (March in Los Angeles).

Re: Rapid prototype for lost wax method of bronze casting

I'm not sure about RP for art bronze castings; there are people doing this for industry, but art lags behind a little. There are lots of companies doing this for jewelers, though, on a smaller scale, using wax-like materials that burn out readily to cast gold, silver, and platinum. Here's one in LA: http://rpwax.com/

There are companies that use CNC milling (subtractive rapid prototyping) to make originals for art casting; Kreysler and Assoc. is one. (www.kreysler.com). They typically carve a large piece in urethane foam and surface it with oilclay, allowing the sculptor to determine the final texture. This is then molded, wax is cast into the mold, and the lost-wax process proceeds normally from there.

Re: Rapid prototype for lost wax method of bronze casting

I understand that this is done with CAD and manufacturing of tooling. I suppose what I am looking for is a company that is venturing out and doing it with art on a larger scale art. I would be open to any company at this point as they many know of others in their industry. I also know that the technology and hardware often has to "catch up" to the needs of the artists as is the case with rapid prototyping in bronze and gold done by the one company that I found. I'll post their name when I get back. Thanks and keep the suggestions coming.

Re: Rapid prototype for lost wax method of bronze casting

Yes I am familiar with the milling process as I wrote about it for Sculptural Review and created this video

and have worked with both Blue Genie and Synappsys. Thanks for the input please keep it coming.

You might PM Josh - he seemed in the loop with regard to RP and casting:

Re: Rapid prototype for lost wax method of bronze casting

I am familiar with quite a few processes that work well for burnout. It really depends on scale, resolution requirements, furnace capabilities of foundry, budget, etc. Let me know your requirements & I can try to make some appropriate suggestions.

Re: Rapid prototype for lost wax method of bronze casting

I am interested in all sizes and for fine art. I may just mention one or two in the book, but would like to gather a list of resources for the accompanying website that the publisher has requested we have. I would also like to learn more about these process to create videos. Anywhere you want to start and any numbers and contacts that you want to pass on is greatly appreciated.

Re: Rapid prototype for lost wax method of bronze casting

To really go into any kind of detail about all the various processes would take a publication in itself. On broad terms, do searches for "rapid prototyping investment casting patterns" or maybe "wax 3d printers". Many of the leading manufacturers of 3D printers offer materials or technologies that either are developed particularly for burn out or work acceptably well. The processes & techniques range from applications developed for dentistry, to casting engine blocks, to fine arts. All have their strengths & weaknesses depending on the geometry, scale, resolution & budget your working within. Again, to list out the pros & cons of each would be intensive and I'm sure spark a rebuttal by an endless list of vendors touting their services rather than unbiased info.

Re: Rapid prototype for lost wax method of bronze casting

There are machines by Solidscape and Sanders that print wax. These are know for their tight surfaces. Also, Solid Concepts has a quick cast epoxy for burnout with ceramic shell. You will need watertight stl models to use these processes.

Re: Rapid prototype for lost wax method of bronze casting

Hi... I am a 3d modeler, and help artists make their sculptures - I worked with an RP firm in LA that did this alot. We made "QuickCast" Patterns -- with an SLA machine, resin parts are made hollow, with a honeycomb lattice structure on the inside so they burn out easily without cracking the ceramic mold. This replaces your wax! So, you skip making the clay positive, rubber mold, and wax pattern stages. But you have to do it in 3d...and you only get one shot with the prototype!

Re: Rapid prototype for lost wax method of bronze casting

Here are some resources in Australia. I haven't used either so I can't recommend them.

Re: Rapid prototype for lost wax method of bronze casting

I know this is an old post but believe it or not, I'm just now getting to this chapter of the book. I will look up all of the things suggested. I am specifically looking for digital printing for lost wax method of bronze casting. Though I would also like to know of some companies that do digital milling in wood. or other materials using digital printing and milling. I have enough of the foam/clay stuff. I'm looking or other. The idea is that digital sculpture could be output to these vendors.

Thanks in advance, keep the information coming.

Re: Rapid prototype for lost wax method of bronze casting

Kaizen. I don't see where the two places that you mentioned actually print wax from a digital file. Did I miss this?

Re: Rapid prototype for lost wax method of bronze casting

the Zcorp cornstarch / parafin works pretty well (cheap, but not the best for resolution, only 0.007in layer thickness) otherwise nylon burns out fine too, from what I have seen anyway - we use a Zcorp machine combined with either scanning (minolta) or direct 3D modeling for our stuff, work great.
