The invention discloses a bionic multifunctional thermal protection structure based on SLM forming. An SLM technology is adopted to realize the forming of the structure and the bionic multifunctionalthermal protection structure comprises a panel layer and a functional layer, wherein the functional layer is composed of a tubular structure and an internal microstructure, and cross-linking with a certain size between pipes of adjacent layers is guaranteed, so that firm connection in the structure is achieved. According to the invention, the novel bionic multifunctional thermal protection structure is designed according to the bionics principle and based on gulfweed microstructure characteristics, when the structure is interacted with air flow, the structure is subjected to the dual actions of thermal load and impact load, a heat transfer mode is changed under the action of the functional layer, compared with a structure without the microstructure, the bionic multifunctional thermal protection structure is obviou
