Abstract
Laser based powder bed fusion (L-PBF) is used to manufacture parts layer by layer with the energy of laser beam. The use of L-PBF for building functional parts originates from the design freedom, flexibility, customizability, and energy efficiency of products applied in dynamic application fields such as aerospace and automotive. There are challenges and drawbacks that need to be defined and overcome before its adaptation next to rivaling traditional manufacturing methods. Factors such as high cost of L-PBF machines, metal powder, post-preprocessing, and low productivity may deter its acceptance as a mainstream manufacturing technique. Understanding the key cost drivers of L-PBF that influence productivity throughout the whole lifespan of products will facilitate the decision-making process. Functional and operational decisions can yield profitability and increase competitiveness among advanced manufacturing sectors. Identifying the relationships between the phases of the life cycle of products influences cost-effectiveness. The aim of the study is to investigate the life cycle cost (LCC) and the impact of design to it in additive manufacturing (AM) with L-PBF. The article provides a review of simulation driven design for additive manufacturing (simulation driven DfAM) and LCC for metallic L-PBF processes and examines the state of the art to outline the merits, demerits, design rules, and life cycle models of L-PBF. Practical case studies of L-PBF are discussed and analysis of the interrelating factors of the different life phases are presented. This study shows that simulation driven DfAM in the design phase increases the productivity throughout the whole production and life span of L-PBF parts. The LCC model covers the whole holistic lifecycle engineering of products and offers guidelines for decision making.
Highlights
Additive manufacturing (AM), known as 3D printing, is “a process of joining materials to produce parts based on three-dimensional (3D) modelling, usually layer upon layer, as opposed to subtractive manufacturing and formative manufacturing methodologies” [1]
This paper aims to show how simulation driven design for additive manufacturing (simulation may be utilized with attention to the effect on part quality and accompanying life cycle cost (LCC)
Concerning LCC, it becomes evident that the topic has gained measurable attention in the manufacturing sector, the number of publications addressing metal additive manufacturing (AM) is limited
Summary
Additive manufacturing (AM), known as 3D printing, is “a process of joining materials to produce parts based on three-dimensional (3D) modelling, usually layer upon layer, as opposed to subtractive manufacturing and formative manufacturing methodologies” [1]. The scarcity of available literature on the cost-efficiency and lacking reports from industrial scientific sectors currently limit AM industrial full implementation [10,11,12] as published data are often highly case-specific.
