The FDM 3D Printing Application for Orthopedic Splints

Abstract

The FDM technology is an easy solution when someone need freedom of design but with a high precision of manufacturing and so, one can built conceptual models or molds, engineering models, manufacturing tools, and functional testing prototypes. The problem addressed in this paper is to identify and investigate the possibility of design and the achieving sustainability of a temporary hand prosthesis used for supporting and immobilizing a broken bone. The research tries to highlight some common and distinct aspects specific to FDM printing technology. One of the objectives of this paper is to use the FDM technology in order to achieve a modern version of the classics splints or of the orthopedic cast. The prototype models proposed can be made vertically on a 3D printer with small motherboard and are easy to wear, attractive to children through its colors and can be made with a manufacturing low price.

Portable selfcentred device with calibrated rollers

“…• High manoeuvrability, so as to ensure quick measurement of the considered deviation; • Zeroing quick and easy, without requiring costly additional accessories; • High degree of universality that would ensure a measuring range as large as possible; • The indicator instrument: the control device to be fitted with indicator instrument; • The degree of mobility: control device to be portable; • Fixing and positioning elements: the control device must have in its structure, fixing and positioning elements for instrument indicator, respectively its orientation relative to the controlled workpiece [6,7].…”
