China3D printingNet August 16th, a team from Pennsylvania State University (PSU) has received US$75,000 to develop its3D printingConcrete system.
US$50,000 of this funding comes from the School of Engineering’s Innovation and Entrepreneurship Engineering (ENGINE) funding program, and another US$25,000 comes from the School of Art and Architecture.
Participating in NASA’s3D printingAfter the Mars Habitat Challenge, the PSU team is designing high-performance, sustainable concrete3D printingTechnology, its new cement-based mixture will be used with its six-axis robotic additive manufacturing machine. This enables the construction of complex and effective structures.
“Concrete3D printingThe technology still has a broad development prospects to replace existing methods, and it can economically construct traditional buildings. “PSU MarsCrete project lead researcher, residential architecture professor Bernard and Henrietta Hankin professor Ali Memari said.
“On the contrary, this technology is more useful for complex designs, because the traditional method of using templates will be more expensive.”

The multidisciplinary PSU team consists of teachers from the School of Engineering Design, Technology and Professional Courses (SEDTAPP), the School of Art and Architecture, and the Stuckeman Design Computing Center (SCDC).As SCDC professor José Pinto Duarté stated, this collaboration aims to solve concrete3D printingComplex issues.
“Given the breadth and depth of knowledge required, it will be quite difficult for a single investigator to conduct meaningful research in this field at a reasonable speed. Therefore, multidisciplinary cooperation between researchers with different expertise is essential.”
Due to NASA’s 2017 challenge, a concrete3D printingMachine system, the system is equipped with dual mixers and pumps, and the nozzles are manipulated by an industrial six-axis robotic arm. The grant is accelerating the development and testing of new cement mixtures for the system.
Sven Bilén, head of SEDTAPP, explained: “The concrete formulation and the printer system are tightly coupled because one design affects the other’s design.
We must work from micro to large scale. Our work is also closely integrated with architectural design that can be achieved through our materials and printing methods. All three aspects: materials, printing systems and construction must be considered at the same time. “

Conventional and additive manufactured cement
According to the PSU team, traditional concrete consists of ordinary Portland cement (OPC), water, sand, etc. It takes 1,700 to 1,800 megajoules of energy to produce one ton of OPC, which is enough to power 500 100-watt bulbs for 10 hours. This process also emits approximately one ton of carbon dioxide into the earth’s atmosphere.Material mixtures, characterization and design, and additive manufacturing processes and systems are being improved and tested to counter the negative effects of each variable.Researchers believe that this will allow more control3D printingThe system finally realizes the production of complex structures.
