Today’s 3D print service is Proto Technologies, Inc., of Washington State. Their claim to fame is that customers can access a multi-material capable Object Connex 500 3D printer. Readers may recall this amazing device has two media hoppers that can hold completely different build materials, enabling one-step printing of objects having hard and soft portions, for example.
ProtoTech also offers StereoLithography via a 3D Systems 500 as well as conventional milling and machining.
