Analysis and Optimization of Forming Quality of 3D Concrete Printing Materials Liu Shiping1,a, Ma Ziyan1,b*, Xia Wenjie1,c and Huang Yuanjing1,d 1School of Mechanical Science and Engineering, Huazhong University of Science and Technology, China aliushiping@hust.edu.cn, bM202070771@hust.edu.cn, c M202078368@hust.edu.cn, dM201970371@hust.edu.cn Keywords: 3D concrete printing; concrete material; forming quality Abstract. 3D concrete printing is a kind of construction method that takes concrete as processing material for extrusion forming.
In this paper, the error sources of concrete printed parts are discussed firstly, and the forming quality of the printed parts material is analyzed in combination with GD&T system and concrete structure engineering construction quality acceptance specifications.
At present, researchers have basically reached a partial consensus that the special rheology of concrete materials is one of the key factors leading to the deformation of the material under its own weight.
As a result, how to make the wet accumulation material have better fluidity and low plasticity is the key to the research of concrete materials.
Research on related aspects is the basis and key to improving the forming quality and technical construction of 3D concrete printing materials.

Superalloy Technology-A Perspective on Critical Innovations for Turbine Engines Robert Schafrik1,a and Robert Sprague2,b 1 GE Aviation, Materials & Process Engineering Department, 1 Neumann Way, M/D H85, Cincinnati, OH 45241, USA a robert.schafrik@ge.com 2 GE Aviation, Materials & Process Engineering Department, retired b robert.sprague@mac.com Keywords: high temperature structural materials, nickel-based superalloys, aeropropulsion, vacuum arc melting, investment casting, forging, materials modeling Abstract: High temperature structural materials, such as nickel-based superalloys, have contributed immensely to societal benefit.
Given the long time required for materials development, design engineers could not accurately foresee what material would be needed in 10 years since they were focused on engineering the next generation engine, not the generation afterwards.
Materials and process advancements have played a key role in this adventure.
The key elements of this new materials development paradigm include: • The new paradigm is system engineering centric, requiring that proposed materials capability be aligned to design requirements, and critical-to-success metrics identified that can focus resources to assure implementation success.
This linkage insures that the appropriate engineering design practices are in place to allow usage of the material
