Resumo
A tecnologia de manufatura aditiva já se tornou uma importante ferramenta para os ramos de pesquisa e de desenvolvimento de produtos nas indústrias, universidades e sociedade em geral. Devido a rapidez e baixo custo de produção de protótipos ou até mesmo partes funcionais de um mecanismo, essa tecnologia ganha espaço a cada dia e abre portas para novas linhas de pesquisa. Da mesma maneira que a área de desenvolvimento de produtos, a engenharia de tecidos tem a cada dia avançado no desenvolvimento de materiais e processos capazes de produzir tecidos, órgãos e próteses de forma rápida, segura e que possam ser implantados em organismos vivos permitindo a regeneração de tecidos perdidos ou mesmo implantados de forma a solucionar problemas de saúde ou possibilitar melhor qualidade de vida seja a um ser humanos ou animal. Dessa forma a área de engenharia de biomateriais tem trabalhado em pesquisas e desenvolvimentos de materiais que possuam propriedades adequadas a aplicação em engenharia de tecidos. Tal tarefa é dificultada pela falta de equipamentos capazes de transformar os materiais desenvolvidos em modelos tridimensionais com propriedades químicas e físicas ideais para a aplicação em regeneração óssea, seja pela indisponibilidade de impressoras adequadas ou pelo alto custo de aquisição de máquinas sofisticadas. Por este motivo, o este trabalho possibilitou o desenvolvimento de uma impressora 3d capaz de imprimir modelos tridimensionais a partir de filamentos compostos de biomaterial. Além do desenvolvimento, também foi explorado e apresentado os parâmetros de impressão de acordo com as características do biomaterial utilizado, contribuindo assim para o avanço dos estudos e ensaios práticos do comportamento desses materiais na regeneração de tecidos de forma rápida, precisa e a um custo acessível.
Additive manufacturing technology has already become an important tool for research and product development in industries and universities. Due to the speed and low cost of producing prototypes or even functional parts of a mechanism, this technology gains space every day and opens doors to new lines of research. In the same way as the area of product development, tissue engineering has advanced every day in the development of materials and processes capable of producing tissues, organs and prostheses quickly, safely and that can be implanted in living organisms allowing regeneration. of lost or even implanted tissues in order to solve health problems or provide a better quality of life for both humans and animals. Thus, the area of biomaterials engineering has been working on research and development of materials that have suitable properties for application in tissue engineering. This task is hampered by the lack of equipment capable of transforming the materials developed into three-dimensional models with ideal chemical and physical properties for application in bone regeneration, either due to the unavailability of suitable printers or the high cost of acquiring sophisticated machines. For this reason, this work enabled the development of a 3d printer capable of printing three-dimensional models from filaments composed of biomaterial. In addition to the development, the printing parameters were also explored and presented according to the characteristics of the biomaterial used, thus contributing to the advancement of studies and practical tests of the behavior of these materials in tissue regeneration quickly, accurately and at an affordable cost.
