Research of materials properties for 3D printing of orthoses
Abstract
In this paper examines the possibilities of applying 3D printing in the manufacture of orthoses. Features of 3D printing of biocompatible materials are analyzed. In this work, mechanical bending tests of three printed samples were performed. Based on test results, PETG material is selected for 3D modeling and printing. Technological properties of 3D printing were summarized. Modeling and printing of the orthoses prototype, compared to traditional methods, takes less time, and uses lower material costs, does not require much physical effort, is well suited to the patient’s body anatomy, and has a variety of design options.

Medžiagų, skirtų ortopedinių įtvarų 3D spaudai, savybių tyrimas
Santrauka
Straipsnyje nagrinėjamos 3D spaudos taikymo ortopedinių įtvarų gamyboje galimybės. Nagrinėjami biologiškai suderinamų medžiagų 3D spaudos ypatumai. Darbe atlikti trijų atspausdintų bandinių mechaninio lenkimo bandymai. Remiantis bandymų rezultatais, 3D modeliavimui bei spausdinimui parenkama PETG medžiaga. Pateikiama spausdinimo technologinių parametrų suvestinė. Įtvaro prototipo modeliavimas bei spausdinimas, lyginant su tradiciniu būdu gaminamais įtvarais, užtrunka mažiau laiko, sunaudojami mažesni medžiagų kaštai, nereikalauja daug fizinių pastangų, puikiai atitinka paciento kūno anatomiją, turi įvairaus dizaino galimybę.
Reikšminiai žodžiai: ortopedinis įtvaras, mechaninės savybės, 3D modeliavimas, 3D spauda.
