Abstract: A method is disclosed for making an article with an additive manufacturing machine that includes a build platform (14) and an additive material dispensing nozzle (18) for controlled application of the additive material with respect to a location of the build platform. The method includes attaching a first part (24a) to the build platform. The first part includes a first mating surface that includes a protruding portion (34) and a recessed portion (32). A digital model of a second part that includes a second mating surface comprising recessed and protruding portions (39, 38) complementary to the first mating surface is inputted to the additive manufacturing machine. The nozzle dispenses and hardens an incremental quantity of a polymer material to the first mating surface according to the digital model, and successively-dispensed incremental quantities of polymer material are applied and hardened according to the digital model to produce the article including first and second parts.
