Direct Digital Manufacturing (DDM) is a 3D Printing technology that uses additive fabrication techniques to create prototypes and functional parts right from digital 3D CAD files.
With DDM, production volume is exactly that - a volume, expressed in the total cubic inches produced per year. DDM has a relatively high design complexity. Even though DDM can produce simple products, there are greater cost and time advantages with complex-shaped products. DDM is capable of handling any geometry, no matter how intricate.
A single injection mold can cost tens of thousands of dollars and can take from eight to 16 weeks to make. Products made with DDM require no tooling costs and no waiting for the first production parts. This reduces the start-up investment for a new product. A lower initial investment on one product frees a company to potentially introduce others.
