Not only is 3D printing a wonderful, versatile method of fabrication on its own, but it's also turned out to play an important role alongside other, much older techniques in many cases. Investment casting is one of the oldest manufacturing methods in existence, and although it was first used thousands of years ago, it's still a common, useful method of creating metal pieces today. 3D printing has complemented it well, proving that even reliable, time-tested techniques can benefit from new technology. A recent case study shows how Spectra3D used colorFabb filament to 3D print investment casting patterns for a client, delivering high-quality parts for a low cost.
