[0005] The utility model is further configured such that the first buffer surface is provided with a limiting surface with a central protrusion, the front end of the seat support portion is located directly above the limiting surface, and there is a gap between the seat support portion and the limiting surface, when the seat support portion is subjected to a higher impact force, the seat support portion moves downward and abuts against the limiting surface, thereby avoiding damage to the buffer portion due to excessive deformation.

[0006] The utility model is further configured such that the base portion is provided with an inner concave surface and supporting feet distributed around the inner concave surface, the inner concave surface is arranged at the center of the base portion, and naturally forms four supporting feet distributed in a rectangular shape, and the four supporting feet are placed on the ground at the same time, which is conducive to maintaining the balance of the seat body.

[0007] The utility model is further configured such that a step surface for placing feet is provided at the connection between the outer elastic part and the bottom foot part. The step surface is designed by changing the shape to facilitate placing feet and improve comfort.

[0008] The utility model is further configured such that a back support surface is formed at a connection between the seat support portion and the rear support portion, and the back support surface is designed by changing the appearance to facilitate supporting the back waist and improve comfort.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The seat body is made of one-piece 3D printing technology, and the overall shape is novel and beautiful, with market competitiveness.

[0011] 2. When a human body sits on the seat support, the force generated acts on the buffer part, and the first buffer surface and the second buffer surface are deformed at the same time to play a buffering role, thereby preventing the seat body from being cracked and damaged by impact, thereby improving the service life and comfort of the seat body.

[0017] like Figure 1-3 As shown, the present embodiment provides an integrally formed 3D printed bar chair, comprising an integrally formed seat body 1, the seat body 1 comprising a seat support portion 2, a rear support portion 3, a foot portion 4 and a buffer portion 5 which are distributed in a ring shape, the buffer portion 5 comprising an outer elastic portion 6, a transition portion 7 and an inner elastic portion 8 which are distributed in an S shape, the transition portion 7 respectively forming a first buffer surface 11 and a second buffer surface 12 with the outer elastic portion 6 and the inner elastic portion 8, the outer elastic portion 6 is connected to the foot portion 4, the inner elastic portion 8 is connected to the seat support portion 2, and the front end of the seat support portion 2 is located directly above the first buffer surface 11.

[0018] In the utility model, the seat body 1 is made of an integral piece by a 3D printing process. When a human body sits on the seat support portion 2, the force generated acts on the buffer portion 5. At this time, the first buffer surface 11 and the second buffer surface 12 are deformed at the same time and play a buffering role, thereby preventing the seat body 1 from being impacted and cracked, thereby improving the service life and comfort of the seat body 1.

[0019] In this embodiment, the first buffer surface 11 is provided with a limiting surface 13 with a central protrusion, the front end of the seat support portion 2 is located directly above the limiting surface 13, and there is a gap between the seat support portion 2 and the limiting surface 13. When the seat support portion 2 is subjected to a high impact force, the seat support portion 2 moves downward and abuts against the limiting surface 13, thereby preventing the buffer portion 5 from being damaged due to excessive deformation.

[0020] In this embodiment, the base portion 4 is provided with an inner concave surface 14 and supporting feet 15 distributed around the inner concave surface 14. The inner concave surface 14 is provided at the center of the base portion 4 and naturally forms four supporting feet 15 distributed in a rectangular shape. The four supporting feet 15 are placed on the ground at the same time, which helps the seat body 1 to maintain balance.
