Abstract
A method of analytically determining a laser power for laser sintering includes choosing a batch of powder material for building a plurality of test rods; selecting a range of laser power for building the test rods; determining a plurality of power increments within the selected range to define a plurality of laser power settings; programming a laser sintering machine to build at least one test rod at each laser power setting; constructing the test rods; wherein the optimal power is at least one watt below a lowest laser power setting associated with the formation of voids; identifying the laser power setting used to construct a respective test rod without formation of voids in the surface as an optimal laser power; and configuring the selective laser sintering machine with the optimal laser power when conducting a laser sintering process using the chosen batch of powder material.
