detailed description

As shown in Figures 1-5, the portable structural parts applicable to most of the biological 3D printing of the human body include a foldable bracket, and a chassis or frame for installing the foldable bracket. The chassis includes a rubber base 1, a metal Frame 2, linear slide rail 3, brakeable slider 4 and square hole 5; the rubber base 1 is located at the bottom of the metal frame 2, and the square holes 5 are arranged on the four corners of the metal frame. The linear slide rail 3 is arranged on the two long sides of the metal frame 2, and the brakeable slider 4 is arranged on the linear slide rail 3; the square hole 5 is used for installing a foldable bracket;

The frame includes a metal frame 2, a linear slide 3, a brakeable slider 4 and a connecting piece 6; the linear slide 3 is arranged on two long sides of the metal frame 2, and the brakeable The slider 4 is arranged on the linear slide rail 3; the brakeable slider 4 is provided with a connecting piece 6 for installing a foldable bracket; the four corners of the metal frame 2 are provided with installation holes for The lower part of the metal frame 2 is equipped with a foldable support.

The foldable support can be opened when in use to support a certain height; it can be folded when not in use, thereby reducing the volume.

The lower part of the foldable bracket installed on the lower part of the metal frame is equipped with plastic semicircular buckles 7 for connecting with the metal rods on both sides of the stretcher.

In the present invention, when printing arms, legs, and face, the linear motion platform can be directly inserted into the square hole on the chassis 1 through the foldable bracket 2 to achieve connection, so as to perform biological 3D printing on the wound; when printing the back, xyz linear The motion platform can be connected with the slider on the guide rail of the frame 3 through the foldable bracket 2, and the linear motion platform can be moved to the wound on the back through manual movement and the brakeable slider 4, so as to realize the biological 3D printing of small injuries on the back, sliding The block connection 5 can be connected to the brake slide 4 by means of a screw connection.

The chassis 1 is placed on the ground to realize the overall support function, and a rubber chassis is installed under the metal part of the chassis, which increases friction and buffering with the ground, and increases stability to a certain extent.
