The relentless pursuit of performance and perfection in manufactured parts drives us to adopt new manufacturing technologies. In the realm of composite parts, additive manufacturing offers highly attractive alternatives in terms of manufacturing costs and possibilities. In this study, we propose to explore this manufacturing process using a Markforged 3D printer, renowned for its expertise in 3D printing composite materials utilizing two extruders. The primary material investigated for the parts is Onyx, which will be reinforced with four types of fibers: carbon, glass, High-Strength High-Temperature (HSHT) glass, and Kevlar fibers. The overall objective is to propose a method for analyzing the results and experiments conducted through a multicriteria optimization approach. The proposed method aims to push the limits of optimization by applying inventive design methods, aiming to overcome the Pareto frontier defined by the experiments. The approach followed in the article is based on TRIZ. Solution concepts have been proposed to enhance the relevance of 3D printing.

摘要

The relentless pursuit of performance and perfection in manufactured parts drives us to adopt new manufacturing technologies. In the realm of composite parts, additive manufacturing offers highly attractive alternatives in terms of manufacturing costs and possibilities. In this study, we propose to explore this manufacturing process using a Markforged 3D printer, renowned for its expertise in 3D printing composite materials utilizing two extruders. The primary material investigated for the parts is Onyx, which will be reinforced with four types of fibers: carbon, glass, High-Strength High-Temperature (HSHT) glass, and Kevlar fibers. The overall objective is to propose a method for analyzing the results and experiments conducted through a multicriteria optimization approach. The proposed method aims to push the limits of optimization by applying inventive design methods, aiming to overcome the Pareto frontier defined by the experiments. The approach followed in the article is based on TRIZ. Solution concepts have been proposed to enhance the relevance of 3D printing.
