Described herein are electroless material deposition methods and techniques that can be used to deposit one or more materials on a structure in a selective manner such that deposition can occur in predetermined areas. The methods and techniques of selective electroless material deposition methods described herein can be used to selectively deposit material(s) on 3D printed structures. In some aspects, the 3D structures can contain micro-features that can have one or more materials selectively deposited on their surface in one or more locations.
