Abstract

The influence of thin plate prevented the projection of particles under laser heating is analyzed analytically and numerically. It was shown that the conjugate heat exchange between different materials changes not only absorbed heat quality during the heating but affect the kind of the dependence for the temperature on time. Temperature distribution for different time moments is illustrated for two particular cases. Half-transparent plate and half-transparent heated material are discussed. The results are useful to understand the physical phenomena in additive manufacturing.
