“…The selected material was fabricated by using an Objet 350 3D printer and a polypropylene-based photopolymer called Objet Durus White RGD430 in 2014 [135]. In 2016, Li et al [136] proposed a density-aware internal support structure modeling scheme in order to realize the lightweight modeling of 3D-printing model which conforms to the mechanical characteristics. The Density-Controllable internal support structure was generated according to the structural analysis.…”

In the field of mechanical equipment manufacturing, the focus of research and development is not on weight reduction, but on how to choose between the rigidity and performance of components (such as strength or flexibility). For this contradiction, lightweight is one of the best solutions. The problems associated with lightweight were initially considered and systematically studied in aircraft manufacturing in engineering. Therefore, lightweight has been greatly developed in aviation research and has played an increasingly important role in construction machinery. This paper presents a brief description of the current status of lightweight in machinery by reviewing some significant progress made in the last decades. Potential research topics are also discussed from the four aspects of material, structure, bionics, and manufacturing, and they forecast the development trend of lightweight in the future construction machinery. The entire body of literature about the field is not covered due to the limitation of the length of paper. The scope of this review is limited and closely related to the development of lightweight technology in engineering applications.

“…One of the studies [13] presented bone-like porous structures, and another [14] was proposed anisotropic porous structures based on anisotropic centroidal Voronoi tessellations. In the study [15], researchers developed a density-aware internal porous supporting structure to improve the structural soundness of 3D fabrications. The above studies propose more options for the interior design of 3D fabrications in order to improve mechanical performance and minimize material consumption.…”

This article presents a multilevel design for infill patterns. The method partitions an input model into subareas and each subarea are applied with different scales of infill patterns. The number of subareas can be decided by users. For each subarea, there are different values of the scaling parameter that determines the number of columns and rows of pattern elements, which is useful to change the weight and strength of a certain area by user demands. Subareas can be symmetric or asymmetric to each other depending on the geometry of a 3D model and the application requirements. In each subarea, there are generated symmetric patterns. The proposed method is also applicable to combining different patterns. The aim of our work is to create lightweight 3D fabrications with lighter interior structures to minimize printing materials and supplementary to strengthen thin parts of objects. Our approach allows for the composition of sparse and dense distributions of patterns of interior 3D fabrications in an efficient way so users can fabricate their own 3D designs.

Virtual reality technology is a technology that uses a variety of scientific technologies such as computer systems, image displays, and sensors to perform human-computer interaction. Since the advent of virtual reality technology, the virtual reality + medical model has been highly expected. At present, three-dimensional (3D) animation technology can be used in combination with virtual reality technology in medical systems. 3D animation technology can transform the transformed human medical image into a 3D character model, and animate the corresponding bones, and observe the model on the screen and operate the model like real surgery, completing virtual medical content learning, virtual medical skill training, virtual surgery preview. Applying 3D animation technology to virtual reality surgery training can effectively bypass the limitations of traditional surgery training modes, form multiple interactive real-time effects, and bring a rich perceptual experience to the audience. Based on the above background, the research content of this article is the study of virtual medical system animation under the background of virtual reality technology. This paper analyzes the feasibility of virtual reality technology and 3D animation modeling, and designs a virtual medical Liang Li and Tingting Li are co-first authors.
