Rapid filament prototyping of a bionic hand

Abstract

No matter how we call it: additive manufacturing, fast manufacturing, fast prototyping, fabrication in layers or DMF (desktop manufacturing) manufacturing, 3D printing is rapidly developing due to the diversity of applicability areas. In this paper, we would like to introduce the way of realizing a bionic hand that imitates human hand movements with the help of the 3D printer. The actual function that can perform is the movement of the finger segments for closing and opening the fist. The imprint was made using the Creality 3D Direct Store 3D Ender 3 3D Printer Original. As components, we have the handprint, the print of servomotor holder, the Arduino uno board, the breadboard, 5 actuators, male jumpers and fishing thread for ligaments. For programming, the integrated development IDE environment based on the Processing project has been used, which includes support for the C and C ++ programming languages.

Study on the influence of technological parameters on 3D printing with sla technology

“…The general concept and the procedure to be used in 3D-printing was first described by Raymond F. Jones in his short story, "Tools of the Trade," published in the November 1950 issue of Astounding Science Fiction magazine. He referred to it as a "molecular spray" in that story [1,2,3]. Stereolithography or "SLA" printing is an early and widely used 3D printing technology.…”
