Example Embodiment

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] See Figure 1-3 To illustrate this embodiment, a space retractable robotic arm based on 4D printing includes a hollow columnar structure 1, a first pressing plate 2 and a second pressing plate 3. The hollow columnar structure 1 is formed by 4D printing technology, and the hollow columnar The material of the structure 1 is a shape memory polymer, the wall surface of the hollow columnar structure 1 is distributed in a net shape, and the two ends of the hollow columnar structure 1 are respectively connected with the first pressing plate 2 and the second pressing plate 3.

[0024] The shape memory polymer of the present invention is a polylactic acid material, which has thermoplasticity and shape memory effects, can be actively deformed under thermal excitation conditions, is dire...

Abstract

The invention provides a space scalable type mechanical arm based on 4D printing and an expanding and contracting method thereof, belongs to the fields of 4D printing technologies and shape memory polymer, and particularly relates to a space scalable type mechanical arm based on 4D printing and an expanding and contracting method thereof. The problem that application of the 4D printing technologyon the aspect of printing a three-dimensional space expandable structure is poor is solved. The space scalable type mechanical arm comprises a hollow cylindrical structure, a first pressing plate anda second pressing plate and is mainly applied to astronautic three-dimensional intelligent space expanding structures.

Description

technical field [0001] The invention belongs to the field of 4D printing technology and shape memory polymers, in particular to a 4D printing-based space-stretchable mechanical arm and a stretching method thereof. Background technique [0002] 4D printing refers to the three-dimensional objects processed by 3D printing. Under specific environment and excitation (such as electricity, light, magnetism, water, heat and sound, etc.), its physical characteristics and functions (such as structure, shape, size, etc.) ) can transform itself over time. 4D printing is the further development and perfection of 3D printing. The most important feature of 4D printing is that it can directly embed the design into the printing material in a programmed way, and after printing, the object can be deformed into the desired shape or function in a predetermined environment or under a specific stimulus, which simplifies the process from The process from the design concept to the actual object re...
