The invention relates to hyperbranched polyesteramide as well as a preparation method and application thereof. The hyperbranched polyesteramide is prepared from the following raw materials: dihydric alcohol, dibasic acid and ester derivatives thereof, polybasic acid and an N-containing monomer. The hyperbranched polyesteramide disclosed by the invention has relatively good toughness, flowability and thermal stability, and is suitable for the field of 3D printing. The preparation method takes amino acid as a raw material, and is high in reaction activity, mild and controllable; meanwhile, amino acid is used as a biological resource, is a renewable resource and is environment-friendly. 本发明涉及一种超支化聚酯酰胺及其制备方法与应用，所述超支化聚酯酰胺的制备原料包括：二元醇、二元酸及其酯类衍生物、多元酸、和含N单体。本发明的超支化聚酯酰胺具有较好的韧性、流动性、热稳定性，适用于3D打印领域。本发明的制备方法以氨基酸为原料，反应活性高，温和可控；同时，氨基酸作为生物资源，是可再生资源，环境友好。
