System and methods for fabricating a component using a consolidating device

An additive manufacturing system comprising:

• a material to be consolidated;
• and
• a consolidating device comprising:
• at least one first energy beam generator configured to generate a first energy beam for forming a first melt pool in a layer of material;
• at least one second energy beam generator configured to generate a second energy beam for forming a second melt pool in the layer of material;
• at least one first lens having a first entrance pupil, said first lens positioned between said first energy beam generator and the layer of material, wherein said first lens is a first unilaterally telecentric lens and is configured to receive the first energy beam;
• at least one second lens having a second entrance pupil, said second lens positioned between said first lens and the layer of material, wherein said second lens is a second unilaterally telecentric lens and is configured to receive the first energy beam from said first lens, wherein the first entrance pupil and the second entrance pupil substantially overlap, and wherein said first unilaterally telecentric lens and said second unilaterally telecentric lens create an afocal plane at a midpoint between said first unilaterally telecentric lens and said second unilaterally telecentric lens;
• and
• at least one reflective element positioned between said first lens and said second lens, said reflective element configured to receive the second energy beam and to reflect the second energy beam through said second lens to be incident on the layer of material.
