The invention discloses a reinforced toughened nylon material can be used for 3D printing and a preparation method thereof. The reinforced toughened nylon material is consisted of the following components in percentage by mass: 60%-75% of polyamide 6 (PA6), 10%-20% of glass fiber (GF), 10%-20% of a toughening agent, 4%-8% of a compatibilizer, 0.3%-0.6% of an antioxidant, 0.3%-2% of a coupling agent, and 0.2%-1% of a nucleating agent. The material has the advantages that: 1, the addition of the compatibilizer and the coupling agent remarkably improves the compatibility and the bonding strengthbetween each component, so that the overall performance of the material is obviously improved; 2, the use of a certain diameter long glass fiber reinforcement reduces the shrinkage rate of the material, and improves the serious warpage shortcoming of the material when the material is used for printing; and 3, the addition of the toughening agent solves the shortcoming that the nylon material is lack in toughness after the glass fiber is reinforced, so that consumable printing use is facilitated. Compared with the performance of an existing nylon material, the material prepared in the inventionhas better mechanical properties, higher heat-resistant temperature, and lower molding shrinkage rate, and is not liable to warpage, so that the material is very suitable for preparing FDM-3D printing consumables.
