In concrete construction, <a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\">3D printing<\/a> is expected to move into practical use, and field <a href=\"https:\/\/facfox.com\/news\/topics\/insights\/applications\" target=\"_blank\">application<\/a>s have progressed primarily through material extrusion printing, in which cementitious materials are deposited layer by layer as they are extruded downward. However, this method makes it difficult to integrate rebars into the printed layers, thereby limiting its applicability to reinforced structural components. Spray-based printing, which forms structures by spraying cementitious materials, is better suited to producing reinforced structural components. At the same time, the complexity of printer motion control has made it difficult to ensure sufficient fabrication accuracy, presenting a key technical challenge.<\/p>\n<div style=\"background-color: #eaeaea7a;padding: 15px 30px;align-items: center;border-radius: 4px;box-shadow: -1px 4px 20px 0px #dedede;margin-top: 1em;margin-bottom: 1em\">\n<div style=\"flex: 1;padding-right: 30px\">\n<h4 style=\"margin-bottom: 14px\">Manufacturing on Demand<\/h4>\n<div>Have design to produce?

This approach improves printing accuracy while minimizing defect rates. The gantry robot used for printing consists of a seven-degree-of-freedom arm suspended from a two-axis XY motion mechanism mounted atop a portal-type frame. The printable area spans 6 meters in depth, 4 meters in width, and 3 meters in height. From the nozzle at the arm tip, material can be sprayed in multiple directions across a wide range, allowing it to fill even the interior of reinforced assemblies. In demonstration tests, the system successfully fabricated a twisted curved wall, with both the lower and upper layers projecting outward from the center, measuring 2.5 meters in height, in just four hours.<\/p>\n<p>Once <a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\">3D printing<\/a> of structural components is implemented at construction sites, it is expected to advance labor-saving and workforce reduction in construction production while also increasing design flexibility for structures.

The system integrates a nine-degree-of-freedom gantry robot with a material spray simulator that enables verification of sprayed-material behavior in advance. This enables highly accurate, automated fabrication of reinforced structural components and large components with complex geometries, applications that were difficult to realize using conventional material extrusion printing. The material spray simulator incorporated into the system was jointly developed with the Computational Engineering and Robotics Lab (CERLAB), led by Professor Kenji Shimada of the Department of Mechanical Engineering at Carnegie Mellon University.","breadcrumb":{"@id":"https:\/\/facfox.com\/news\/shimizu-corporation-develops-spray-based-3d-concrete-printing-construction-3d-printing\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/facfox.com\/news\/shimizu-corporation-develops-spray-based-3d-concrete-printing-construction-3d-printing\/"]}]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/facfox.com\/news\/shimizu-corporation-develops-spray-based-3d-concrete-printing-construction-3d-printing\/#primaryimage","url":"https:\/\/facfox.com\/news\/wp-content\/uploads\/2026\/01\/72702a88eab5b37b75460d20c0acbffa.jpg","contentUrl":"https:\/\/facfox.com\/news\/wp-content\/uploads\/2026\/01\/72702a88eab5b37b75460d20c0acbffa.jpg"},{"@type":"BreadcrumbList","@id":"https:\/\/facfox.com\/news\/shimizu-corporation-develops-spray-based-3d-concrete-printing-construction-3d-printing\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/facfox.com\/news\/"},{"@type":"ListItem","position":2,"name":"Shimizu Corporation develops spray-based 3D concrete printing Construction 3D Printing"}]},{"@type":"WebSite","@id":"https:\/\/facfox.com\/news\/#website","url":"https:\/\/facfox.com\/news\/","name":"FacFox News","description":"News and Insights of 3D Printing and Manufacturing","publisher":{"@id":"https:\/\/facfox.com\/news\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/facfox.com\/news\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"},{"@type":"Organization","@id":"https:\/\/facfox.com\/news\/#organization","name":"FacFox News","url":"https:\/\/facfox.com\/news\/","logo":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/facfox.com\/news\/#\/schema\/logo\/image\/","url":"https:\/\/facfox.com\/news\/wp-content\/uploads\/2020\/11\/facfox-news-homepg-logo-200px.png","contentUrl":"https:\/\/facfox.com\/news\/wp-content\/uploads\/2020\/11\/facfox-news-homepg-logo-200px.png","width":200,"height":55,"caption":"FacFox News"},"image":{"@id":"https:\/\/facfox.com\/news\/#\/schema\/logo\/image\/"}},{"@type":"Person","@id":"https:\/\/facfox.com\/news\/#\/schema\/person\/7b701aad2d8f434034fcecd2c50a570c","name":"Vera","image":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/secure.gravatar.com\/avatar\/bf3b1e47e1f0ed2367da10e343584d5a4adb2e9675fce2aefb04f0ecf3954386?s=96&d=mm&r=g","url":"https:\/\/secure.gravatar.com\/avatar\/bf3b1e47e1f0ed2367da10e343584d5a4adb2e9675fce2aefb04f0ecf3954386?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/bf3b1e47e1f0ed2367da10e343584d5a4adb2e9675fce2aefb04f0ecf3954386?s=96&d=mm&r=g","caption":"Vera"},"url":"https:\/\/facfox.com\/news\/author\/vera\/"}]}},"fifu_image_url":"https:\/\/facfox.com\/wp-content\/uploads\/2026\/01\/4697855444417848163.jpg","_links":{"self":[{"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/posts\/196250","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/comments?post=196250"}],"version-history":[{"count":0,"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/posts\/196250\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/media\/196252"}],"wp:attachment":[{"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/media?parent=196250"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/categories?post=196250"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/facfox.com\/news\/wp-json\/wp\/v2\/tags?post=196250"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
