Plans for 3D printed church in Czechia progress Construction 3D Printing

by Architecture

Construction 3D printing technologies are being used to build myriad structures, from student housing blocks, to pedestrian bridges, to military bunkers. Soon, we will see 3D printing used to build a new parish church in Czechia. The project, to be the first of its kind, was recently given the blessing of the Archdiocese of Prague, who recognized the potential of the technology to build a place of worship with an innovative design and acoustics, while also bringing down building costs.

Shimizu Corporation develops spray-based 3D concrete printing Construction 3D Printing

by Architecture

Shimizu Corporation, a Japanese construction, architecture, and engineering firm established in 1804, has developed a spray-based 3D concrete printing system designed for the construction of large, curved reinforced components. 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.

Custom 3D printed models improve precision of oral cancer surgery

by Medical

Custom 3D printed models tailored to individual patients are helping surgeons remove oral cancers with greater precision, according to new research from The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James). In 92 percent of head and neck surgeries that used a 3D model during the operation, complete tumor removal was achieved, compared to 74 percent of surgeries performed without one. Researchers report that this approach allows for more accurate excision of malignant tissue while preserving healthy structures, potentially reducing the need for follow-up treatment.

3D printed flooring marks progress for carbon-negative concrete Research & Education

by Architecture

A team of researchers from the Polyhedral Structures Laboratory at the University of Pennsylvania has unveiled a new flooring installation that demonstrates how 3D printing and cutting-edge design can be combined to create structures that significantly reduce concrete consumption and, consequently, the carbon footprint of construction. The project, called “3D-Printed Dual-Banded High-Performance Concrete Floor”, is led by Dr. Masoud Akbarzadeh, Associate Professor of Architecture and director of the Polyhedral Structures Laboratory (PSL).

3D Systems Secures FDA Clearance to Broaden Adolescent Use of VSP Orthopedics Platform

by Medical

US-based 3D printer manufacturer 3D Systems has received U.S. Food and Drug Administration 510(k) clearance broadening the approved use of its VSP Orthopedics virtual surgical planning and patient-specific instrumentation platform. The clearance now covers skeletally mature adolescents with normal bone structure, in addition to adult patients. This change removes previous regulatory constraints that limited use in adolescent cases and formally brings these procedures within the platform’s labeled indications.
