3d printed concrete technology is a hot research topic in the field of architecture. Printed by layers, the concrete could be stacked accurately in the shape which is digitally designed on computer programs. However, the conventional cement mortar is not suitable for 3D-printing, Because that its aggregate ingredients may cause the cracks in the process of printing. Moreover, the buildability and rheological properties of conventional mortar cannot reach the requirements of 3D-ptinting concrete technology. Ultra-high performance concrete is a developing category of material used in concrete structures and it is considered to be one of the most appropriate printing materials. As the popularization of computer technology, it is a necessary task to research on the digital construction way of concrete structures. And 3D-printing concrete technology combines the popular topics above together. This study mainly introduces the fabrication process of ultra-high performance concrete and digital printing process of 3D-printing concrete, and the mechanical properties of printed specimens are studied by the experimental results.

“…Three‐dimensional (3D) printing is called additive manufacturing, which is a rapid prototyping technology that converts computer‐aided design (CAD) models into 3D structures (Ma & Zhang, 2022). As an emerging digital technology, 3D printing technology could be used in architecture (Yang et al ., 2022), materials engineering (Park et al ., 2022), biomedical engineering (Melnyk & Oyewumi, 2021; Wu et al ., 2022), food technology (Demei et al ., 2022), and even space missions (Terfansky & Thangavelu, 2013). In 2007, a scientific team from Cornell University Godoi used an extrusion‐based printer to print food.…”

Three-dimensional (3D) food printing is a digital food engineering method that has a remarkable application potential in long-term manned spaceflight. Extrusion-based 3D food printing, among the available 3D food printing techniques utilised in the food industry, is one of the most suitable printing methods for manned spaceflight. Extrusion-based 3D food printing could suffice most of the energy and personalised nutritional requirements of astronauts during long-term stay in space by utilising fruits, vegetables, meat products, and nutrients as printing materials. However, 3D food printing in manned spaceflight is still limited by technologies and costs such as printing materials, microgravity, post-processability of food, and engineering transportation under the existing technical conditions. Therefore, this article reviews the 3D food printing and manned spaceflight technologies that are currently available and discusses the challenges involved in 3D food printing in manned spaceflight, thus providing a theoretical basis for future 3D food printing for space missions.
