System and method of making printed articles

A system for forming a product, the system comprising:

• at least one print head region configured to retain:
• a first group of print heads configured to additively print at least a first portion of the product with a first material having a first average particle size, wherein the first average particle size is chosen to impart a first sintering characteristic;
• and
• a second group of print heads configured to additively print at least a second portion of the product with a second material having a second average particle size, wherein the second average particle size is chosen to impart a second sintering characteristic;
• at least one processor configured to:
• receive information reflective of desired properties of the product;
• and
• regulate the first group of print heads and the second group of print heads to distribute the first material and the second material in a layer-by-layer basis to impart differing characteristics to differing portions of the product based on the information reflective of the desired properties of the product.
