Proposição de um procedimento operacional padrão na manufatura aditiva de baixo custo por extrusão de materiais poliméricos na empresa Ovenbird

Abstract

Additive Manufacturing (AM) was developed from technologies created in the 80s of the last century. In this context, another growing market in recent years is the segment of AM for non-industrial purposes, known as low-cost 3D printing. Within this market, the company Ovenbird emerged in 2018, as a startup project by UTFPR-CT students, with the aim of creating a Marketplace focused on 3D printing, with the aim of connecting people who own a home 3D printer with people who wish to acquire an impression. The present work aims to propose a Standard Operating Procedure (SOP) in calibration stages using the technology of extrusion of materials with low cost machines, in the context of the company Ovenbird. The work is justified given the opportunity found in new consumer trends, aiming at the integration of independent 3D printing production systems, as a principle of shared economy, applied to the company’s business model. The procedure needs to be able to guarantee a minimum quality, to be defined based on the analysis of the company’s context, customer needs, and technical characteristics of common problems in low-cost 3D printing. To create the SOP, the MAMP methodology was followed, where the relevant categories and the preparation and maintenance processes that the company would require were identified, the step by step of these processes, in addition to forms and flowcharts to apply in the company’s supply chain. Three suppliers were selected and each one was responsible for printing a category and a model for dimensional analysis. Based on the results, all suppliers who performed the procedure were considered capable of supplying the company and considered certified in accordance with the established process, but two were under observation. The established process is a principle for a procedure that ensures greater control over the printer’s manufacturing conditions and was approved to be applied in a practical way in the supply chain.
