Purpose This paper aims to investigate how the use of 3D printing can facilitate the achievement of lean manufacturing objectives. The main goal of the study is to identify the similarities between the two concepts and evaluate how well they complement each other in terms of improving quality, productivity and reducing costs by eliminating waste. Design/methodology/approach During this study, the methodology involved conducting a thorough and comprehensive examination of existing literature on lean manufacturing and additive manufacturing. The aim was to provide an overview of the relationship between these two concepts and gain insights into areas that require further research. Findings Results obtained indicate a need for more comprehensive and detailed examination of the relationship between lean manufacturing and additive manufacturing in the existing literature. The study highlights the potential synergy between 3D printing and lean manufacturing, suggesting that their integration can enhance quality, productivity, and cost reduction through waste elimination. However, it is important to note that further empirical research is required to validate these findings and quantify the actual impact of combining these two concepts. Research limitations/implications This study’s limitation is that it relies exclusively on a literature review and does not include any experimental testing to verify the suggested connection between lean manufacturing and additive manufacturing. Practical implications This study can help companies understand how the use of 3D printing can aid in achieving lean manufacturing objectives. Additionally, the study can provide insights into best practices for combining lean manufacturing and additive manufacturing and can help companies to optimise the benefits of both. Originality/value The conducted literature review provides valuable insights into the relationship between 3D printing and lean manufacturing. This research contributes to the existing body of knowledge by synthesising and analysing previous studies, highlighting how 3D printing can potentially contribute to the achievement of lean manufacturing goals and how those two concepts can complement each other.

Businesses apply different techniques to keep pace with the incremental competition conditions and changing consumer demands. Lean manufacturing is one of the most effective techniques, which is a systematic approach to identifying and eliminating waste through continuous improvement by flowing the product. The implementation of lean manufacturing starts with the development of Value Stream Maps. A value stream is comprised of all the actions, both value added and non-value added. The main strategy of lean manufacturing, is increasing the operating speed, reducing the duration of flow quality, and improving the cost and delivery performance. This study was carried out at a men’s shirt producer i.e. a ready wear company. First of all, the current state of the production lines was analysed within the scope of the study. Then shirt production lines were organised with the lean manufacturing techniques. As a result, some improvements were made in productivity, quality and lead time.

W biznesie stosuje się różnego rodzaju techniki dla utrzymania konkurencyjności i spełnienia wymagań klienta. Produkcja odchudzona jest jedną z najbardziej efektywnych technik dla systematycznej identyfikacji i eliminacji odpadów. Zastosowanie tej techniki zaczyna się od identyfikacji map strumieni wartości. Podstawową strategią produkcji odchudzonej jest wzrost szybkości operacji, oraz redukcja kosztów i czasu dostawy. Badania przeprowadzono analizując producenta koszul męskich. W efekcie analizy wprowadzono poprawę produkcyjności, jakości i czasu produkcji.

The aim of this paper was to describe influence of variability on production system and how it can be reduced. In the first part it was shown how basic performance indicators of production system - productivity and lead time - are affected by variability. It was also shown that increasing the level of variability always means either worsening productivity or lengthening lead time. Therefore focus on reduction of variability is an important step in accomplishing business excellence. In the second part one can find classification of three existing sources of variability. The first one - random variability is caused by all random events, which happen on production floor (breakdown, stoppages etc). The second one - so-called controlled variability is in most cases the result of management decision (product diversification, the way of production planning etc.). And the third one - uncertainty is out of control for production system (fluctuation in market demand, problems with getting raw materials etc.). At the end of this part the most important causes of variability were gathered. Finally, it was presented how the causes of variability can be reduced by means of "Lean Manufacturing" - the concept, which was developed based on observation of Toyota Production System and focuses on waste reduction out of production system. In this approach the inventory and overproduction is the worst waste and have to be eliminated. As a result, variability is much more visible and can be reduced by different tools of Lean Manufacturing-pull, leveling, U shape cell, one piece flow, visualization, jidoka, continuous improvement, work standardization, Total Productive Maintenance, rapid problem solving and lean design. AH of them was roughly described and for most of them application example from real production system was enclosed. As a conclusion it was proven that reduction of inventory and not utilized capacity without proper attention on variability reduction is very dangerous with respect to productivity. Therefore introduction of Lean Manufacturing should always mean reduction of variability. For further research leave issues related to variability influence on quality, reduction of controlled variability and applying different management concepts for variability reduction.
