Compared to other traditional ways, the number of studies on AM techniques has increased in a noteworthy manner day by day on account of their promising potential for future works. In this paper, fused deposition modeling (FDM) technology was used to fabricate polyethylene terephthalate glycol (PETG) specimens and to analyze the effect of the test speed on their tensile properties. As for the printing parameters, solely layer thickness values (0.1 mm, 0.2 mm, and 0.4 mm) were altered while the other factors were kept constant. In order to ascertain the production effectiveness, hardness and surface roughness measurements were carried out. Uniaxial tensile tests were performed at three different test speeds: 5 mm/min, 25 mm/min, and 50 mm/min. Furthermore, after deformation inspections were conducted both in macro and micro scales to evaluate the failure better. From the damage analyses, it was seen that ductile dominant mixed type failure is valid for lower test speeds even though brittle dominant mixed type failure is detected for 50 mm/min test speed.","PeriodicalId":358444,"journal":{"name":"International Journal of 3D Printing Technologies and Digital Industry","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131854205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bu amaçla, optimizasyon sonucu elde edilen parça geometrisi, sonlu elamanlar analizine tabi tutulmuş ve aynı yükleme koşullarında plastik deformasyon göstermediği gösterilmiştir. Optimize edilmiş geometri, elektron ışınıyla ergitme (EIE) yöntemiyle, Ti6Al4V malzemeden üretilmiş ve parçada meydana gelen boyutsal sapmalar ölçülmüştür. Ölçüm sonuçlarından elde edilen sapmaların, montaj toleransları dahilinde olduğu görülmüştür. Son olarak, üretilen parça statik teste tabi tutulmuş ve numerik sonuçlar ile test sonuçlarının uyumlu olduğu gösterilmiştir. Bütün bu çalışmalar neticesinde, bir uçak parçasının topoloji optimizasyonu ile, aynı yükleme koşullarına dayanacak şekilde, ağırlığının %40.7 oranında azaltılabileceği, EIE yöntemiyle başarılı bir şekilde üretilebileceği ve test verilerine dayanarak, uçakta kullanılabileceği gösterilmiştir.","PeriodicalId":358444,"journal":{"name":"International Journal of 3D Printing Technologies and Digital Industry","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125122576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal comfort means that the majority of the workers in the working environment are in a certain comfort while continuing their physical and mental activities in terms of climatic conditions such as temperature, humidity and air flow rate. If the thermal comfort conditions are insufficient in the working environment, distress is felt and discomfort begins, and accordingly, the working capacity and work efficiency of the person decreases. In this article, temperature physiology and occupational health will be evaluated with fuzzy logic in weaving business. Recognition of risks in the work environment is the most important factor in preventing occupational disease, work-related illness and occupational accidents. The air flow velocity Va (m/s) read from the thermal micro air conditioner is a parameter related to how people in an environment perceive the environment in which the components of personal and environmental factors affecting thermal comfort are expressed mathematically, using PMV and PMV value. The index PPD change, which indicates the rate of change, was determined with the help of fuzzy logic.","PeriodicalId":358444,"journal":{"name":"International Journal of 3D Printing Technologies and Digital Industry","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126367967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From primitive times until today, individuals have faced the problem of decision making in various situations. Decision making is the job of choosing between alternatives. In traditional decisions, data related to the decision process are collected and analyzed, and results are evaluated. However, decisions about situations or problems that people encounter in their daily lives often have more than one and often conflicting criteria. Considering this situation, using heuristic methods to reach a decision is insufficient. Versatile decision-making problems come across businesses and / or organizations in all areas of life. Decision makers mostly make decisions when there are more than one factor and criteria with different scalability. Multiple Criteria Decision Making (MCDM) can be defined as the decision-making process by using at least two criteria within a set of countably finite or uncountable choices. Especially, it will be convenient for managers at strategic level to operate Multi-Criteria Decision Making processes in order to make the most appropriate decision in complex decision problems. Multi-criteria decision making techniques consist of methods aiming to reach the “best fit” solution by using multiple criteria with different scalability. In this study, a Decision Support System that meets the decision-making needs of the manager by operating two different MCDM processes together is proposed. In this context, AHP (Analytic Hierarcy Process) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) MCDM methods were used together. AHP method was used to determine the weights of selection criteria, and TOPSIS method was used to rank the candidates in the light of determined criteria. Both MCDM methods mentioned are described as \"single criteria synthesis approach excluding incommensurability\".","PeriodicalId":358444,"journal":{"name":"International Journal of 3D Printing Technologies and Digital Industry","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125326531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
