Zusammenfassung:	The invention discloses a 3D printing consumable for improving impact resistance, which is in the shape of a long strip filament and comprises a first section part and a second section part which are sequentially connected end to end, the first section part and the second section part are in seamless connection, and the first section part and the second section part are in smooth transition connection; the first section part is made of a thermoplastic material A; the second section part consists of two layers of structures, namely an inner core arranged inside and a sheath wrapping the outer part of the inner core; the outer skin is made of a thermoplastic material A, and the inner core is made of a thermoplastic material B; the toughness of the inner core is greater than that of the sheath; the strength of the outer skin is larger than that of the inner core. The method has the beneficial effects that the impact resistance is improved, the first-layer printing success rate is increased, and the interlayer st
