1. A 3D printer comprising:
a holding area holding material to be used by the 3D printer to produce a part;
at least one component for printing the part through layer-wise additive manufacturing using a 3D printing technology;
a data storage device on which instructions are stored for generating build parameter values, the instructions including empirically derived data, relationships, and/or equations; and
a processor executing instructions stored on the data storage device to perform steps comprising:
receiving values for a public build parameter set and receiving a category for the material wherein the category represents multiple different materials and wherein the material in the holding area is a material within the category;
based on the received category for the material and with at least one property of the material being unknown, selecting instructions for generating build parameter values wherein different instructions are selected for different received categories;
executing the selected instructions for generating the build parameter values to determine values for a private build parameter set that vary based on the properties of the material, wherein the values for the private build parameter set are determined from the received public build parameter set values and the parameters of the private build parameter set are different from the parameters of the public build parameter set used to determine the values for the private build parameter set; and
using the received public build parameter set values and the private build parameter set values to print the part from the material in the holding area using the at least one component.
