It has been noted that the complex geometry and internal lattice structure of AM parts create problems with mechanical suitability. Multifaceted quality requirements and standards complicate the development of quality assurance strategies. Defects in AM parts (porosity, cracks, inclusions, voids, lumpiness and surface roughness) can adversely affect mechanical properties, and some problems such as volume mismatch, layer removal and unwanted internal surface finish cannot be detected by typical mechanical tests . It is also stated that SM continues to dominate AM in terms of quality, accuracy and reliability. The manufacturing industry and investors are always looking to improve technology to reduce costs, energy and expand their capabilities. Beginning in the 1960s, additive manufacturing has since then developed rapidly and continuously, discovering new methods to expand manufacturing capabilities and reinvent the bicycle.","PeriodicalId":104027,"journal":{"name":"International Scientific and Technical conference \"The Progressive Technics, Technology and Engineering Education\"","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139370234","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}

Usually, the high activity of nanotubes leads to the formation of various conglomerates in the solution, and with further application of the aqueous solution, such conglomerates can be transferred to the composite materials being created. Currently, there are no effective fast control tools, and therefore in engineering practice, various fairly complex methods that require specific equipment are often used. Chemography as a method of recording oxidative reactions with ultra-low concentrations of active substances can be successfully used as a means of quick and effective control of the homogeneity of graphene solutions (mainly water-based). Recommendations for the application of the method are given, models are proposed for determining the dispersion of the expected concentration on the controlled surface. A conclusion is made regarding the expediency of monitoring the state and activity of graphene nanotubes.","PeriodicalId":104027,"journal":{"name":"International Scientific and Technical conference \"The Progressive Technics, Technology and Engineering Education\"","volume":"211 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139370305","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}
