In most cases, a scaffold-based\nmethod is used to design porous structures. This approach fails to produce randomly sized and distributed\npores, which is a pressing need as far as the aforementioned application areas are concerned.\nThus, more effective porous structure design methods are required. This article presents how to\nutilize fractal geometry to model porous structures and then print them using 3D printing technology.\nA mathematical procedure was developed to create stochastic point clouds using the affine maps of\na predefined Iterative Function Systems (IFS)-based fractal. In addition, a method is developed to\nmodify a given IFS fractal-generated point cloud. The modification process controls the self-similarity\nlevels of the fractal and ultimately results in a model of porous structure exhibiting randomly sized\nand distributed pores. The model can be transformed into a 3D Computer-Aided Design (CAD)\nmodel using voxel-based modeling or other means for digitization and 3D printing. The efficacy of\nthe proposed method is demonstrated by transforming the Sierpinski Carpet (an IFS-based fractal)\ninto 3D-printed porous structures with randomly sized and distributed pores. Other IFS-based\nfractals than the Sierpinski Carpet can be used to model and fabricate porous structures effectively.\nThis issue remains open for further research", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "MDPI", "subitem_publisher_language": "en"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.3390/fractalfract5020040", "subitem_relation_type_select": "DOI"}}]}, "item_3_select_195": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher", "subitem_select_language": "en"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "AMM Sharif Ullah", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Doriana Marilena D’Addona", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yusuke Seto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shota Yonehara", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akihiko Kubo", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-12-07"}], "download_preview_message": "", "file_order": 0, "filename": "fractalfract-05-00040-v4.pdf", "filesize": [{"value": "4.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 4400000.0, "url": {"url": "https://kitami-it.repo.nii.ac.jp/record/2000341/files/fractalfract-05-00040-v4.pdf"}, "version_id": "c3c81b35-e6ab-48e4-ab7e-248549b34a00"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Utilizing Fractals for Modeling and 3D Printing of Porous Structures", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Utilizing Fractals for Modeling and 3D Printing of Porous Structures", "subitem_title_language": "en"}]}, "item_type_id": "3", "owner": "15", "path": ["1"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/2000341", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-12-07"}, "publish_date": "2022-12-07", "publish_status": "0", "recid": "2000341", "relation": {}, "relation_version_is_last": true, "title": ["Utilizing Fractals for Modeling and 3D Printing of Porous Structures"], "weko_shared_id": 3}
