Construção de um dispositivo de impressão 3D para massa cerâmica adaptado a uma máquina universal de ensaio

Abstract

A large part of the ceramic production sector in Campo Largo is being heavily impacted by external competition, as the portfolio and the manufacturing technologies of these companies are out of date. Enabling the creation of 3D models made with the same raw material of the pieces would help in the creative process and acceptance tests in the market. However, in the context of 3D printing, it is perceived that the market is dominated by polymeric materials as an input for model and batch of customized parts production. The development of a 3D printer, whose input is a ceramic plastic mass, can constitute a competitive differential for these companies, being able to assist both the development of new products and the production of customized parts, in a commercially viable way. Looking at this opportunity, a threedimensional motion device adapted to a universal testing machine was built and tested, which works as a 3D printer with a plastic ceramic mass. This device made possible to study the influence of the process parameters: mass deposition speed and displacement of the printing table on the x, y and z axis. Therefore, the force required to flow the printing mass and the mass variation after drying and burning of a commercial ceramic mass were measured. The best extrusion speeds were 10 and 15% higher than the table traveling speed
