Abstract
The problem of limited throughput in three-dimensional (3D) printing processes is addressed by systems and methods that employ mirrors to receive energy reflected by the melt pool and to redirect such light back to the melt pool, where it may further heat the melt pool. Multiple such passes of reflection from the melt pool and redirection back to the melt pool may substantially increase the efficiency at which the melt pool absorbs the energy, thereby substantially increasing the throughput of the 3D printing process.
