Abstract
Purpose: The implementation of additive manufacturing (AM) or 3D-printer manufacturing for technical prototyping, preproduction series and short production series can bring benefits in terms of reducing cost and time to market in product development. These technologies are beginning to be applied in different industrial sectors and have a great possibility of development. As these technologies are still in development, there is a need to define the capacity of the 3D machines to establish minimum standards for producing high-quality parts.Methodology/Approach: The proposed methodology is based on a design of experiments (DOE) approach, which serves as a guide for engineers when it comes to executing any experimental study. The following steps were followed (Unzueta et al., 2019): Phase 1: define; Phase 2: measure; Phase 3: plan; Phase 4: execute experimentation; Phase 5: analyse the results; Phase 6: improve via confirmation experiments; Phases 7-8: control and standardise.Findings: The proposed methodology is based on a design of experiments (DOE) approach, which serves as a guide for engineers when it comes to executing any experimental study. The following steps were followed (Unzueta et al., 2019): Phase 1: define; Phase 2: measure; Phase 3: plan; Phase 4: execute experimentation; Phase 5: analyse the results; Phase 6: improve via confirmation experiments; Phases 7-8: control and standardise.Originality/Value of paper: This study uses a methodological approach to demonstrate how the 3D printing technology can be enriched with statistical testing techniques (DOE). It defines numerical prediction models to obtain high-quality parts with a new AM technology, using a planning process with a minimum amount of experimentation.
Highlights
Additive manufacturing (AM) is the formalised term used for rapid prototyping, which describes a process used to create systems or parts rapidly before the final presentation of the product
The main objective of this article is to develop an understanding of the behaviour of the different parameters of fusion deposition modelling (FDM) technology framed within AD technologies
This article has demonstrated the importance of the use of experiment design methods to optimise methodologies through minimal experimental effort
Summary
Additive manufacturing (AM) is the formalised term used for rapid prototyping, which describes a process used to create systems or parts rapidly before the final presentation of the product. The term ‘3D printing’, describes the processes of converting a 3D computer-aided design (CAD) model into a stereo lithography (STL) triangular lattice surface model, and creating the solid parts through layer-upon-layer production. In this way, AM changes the way industrial companies operate. AM changes the way industrial companies operate This technology is in the early stages of development, so manufacturers are prudent. This process has mainly been used to create prototypes quickly to verify the details before beginning the formal production process (Gibson, Rosen and Stucker, 2015). The possibility of obtaining parts with better characteristics is currently being studied as an alternative production method that can compete with traditional parts and processes (Narang and Chhabra, 2017; Rayegani and Onwubolu, 2016)
