Development of a low-cost device for photobiomodulation using 3D printing

Abstract

INTRODUCTION: Photobiomodulation therapy (PBM) is a non-pharmacological and non-invasive therapeutic strategy that has shown promising results in several health conditions. Despite important advances in knowledge of its modulatory effects at the molecular, cellular, and tissue levels, the cost of PBM equipment still greatly limits its use in the clinical setting, especially in developing countries. In this context, the use of new technologies such as 3D printing has presented several possibilities for application in the health area. OBJECTIVES: To develop a 3D printing PBM device and test its technical and operational viability. METHODS AND MATERIALS: Development of Health Technology on a Photobiomodulation Device with 3D Printing Tests of the safety, emission, and support of the light beams were carried out. RESULTS: The PBM device demonstrated operational safety and good quality in the maintenance of light beams. CONCLUSION: A three-dimensional (3D) printed LED PBM device is technically, operationally, and financially viable. However, more experimental tests and clinical validation are required before this prototype can be used in human health applications.
