| 1 | Development Trends in Additive Manufacturing and 3D Printing显示文摘Additive manufacturing and 3D printing tech-nology have been developing rapidly in the last 30 years, and indicate great potential for future development. The promising future of this technology makes its impact on traditional industry unpredictable. 3D printing will propel the revolution of fabrication modes forward, and bring in a new era for customized fabrication by realizing the five 'any's: use of almost any material to fabricate any part, in any quantity and any location, for any industrial field. Innovations in material, design, and fabrication processes will be inspired by the merging of 3D-printing technology and processes with traditional manufacturing processes. Finally, 3D printing will become as valuable for manufacturing industries as equivalent and subtractive manufacturing processes. | Bingheng Lu Dichen Li Xiaoyong Tian | 2015 | Engineering2015，1，1： | 48 |
| 2 | 3D printing of bone tissue engineering scaffolds显示文摘Tissue engineering is promising in realizing successful treatments of human body tissue loss that current methods cannot treat well or achieve satisfactory clinical outcomes.In scaffold-based bone tissue engineering,a high performance scaffold underpins the success of a bone tissue engineering strategy and a major direction in the field is to produce bone tissue engineering scaffolds with desirable shape,structural,physical,chemical and biological features for enhanced biological performance and for regenerating complex bone tissues.Three-dimensional(3D)printing can produce customized scaffolds that are highly desirable for bone tissue engineering.The enormous interest in 3D printing and 3D printed objects by the science,engineering and medical communities has led to various developments of the 3D printing technology and wide investigations of 3D printed products in many industries,including biomedical engineering,over the past decade.It is now possible to create novel bone tissue engineering scaffolds with customized shape,architecture,favorable macro-micro structure,wettability,mechanical strength and cellular responses.This article provides a concise review of recent advances in the R&D of 3D printing of bone tissue engineering scaffolds.It also presents our philosophy and research in the designing and fabrication of bone tissue engineering scaffolds through 3D printing. | Chong Wang Wei Huang Yu Zhou Libing He Zhi He Ziling Chen Xiao He Shuo Tian Jiaming Liao Bingheng Lu Yen Wei Min Wang | 2020 | Bioactive Materials2020，5，1： | 20 |
| 3 | Flow Behaviour Analysis and Experimental Investigation for Emitter Micro-channels显示文摘The existing research of the flow behavior in emitter micro-channels mainly focuses on the single-phase flow behavior.And the recent micro-particle image velocimetry(PIV) experimental research on the flow characteristics in various micro-channels mainly focuses on the single-phase fluid flow.However,using an original-size emitter prototype to perform the experiments on the two-phase flow characteristics of the labyrinth channels is seldom reported.In this paper,the practical flow of water,mixed with sand escaped from filtering,in the labyrinth channel,is investigated.And some research work on the clogging mechanism of the labyrinth channel's structure is conducted.Computational fluid dynamics(CFD) analysis has been performed on liquid-solid two-phase flow in labyrinth-channel emitters.Based on flow visualization technology-micro-PIV,the flow in labyrinth channel has been photographed and recorded.The path line graph and velocity vector graph are obtained through the post-treatment of experimental results.The graphs agree well with CFD analysis results,so CFD analysis can be used in optimal design of labyrinth-channel emitters.And the optimized anti-clogging structures of the rectangular channel and zigzag channel have been designed here.The CFD numerical simulation and the micro-PIV experiments analysis on labyrinth-channel emitter,make the 'black box' of the flow behavior in the emitter channel broken.Furthermore,the proposed research promotes an advanced method to evaluate the emitter's performance and can be used to conducting the optimal design of the labyrinth-channel emitters. | WEI Zhengying CAO Meng LIU Xia TANG Yiping LU Bingheng | 2012 | Chinese Journal of Mechanical Engineering2012，25，4： | 11 |
| 4 | Receptance Coupling for Tool Point Dynamics Prediction on Machine Tools显示文摘Chatter has been a primary obstacle to the successful implementation of high speed machining.The frequency response function(FRF) of the tool point is crucial for identification of chatter free cutting conditions.In order to quickly acquire the FRF of the different components combinations of machine tool,the assembly of machine tool was always decomposed into several parts,where the fluted portion of tool,however,was always treated as a uniform beam,and the associated discrepancy was ignored.This paper presents a new method to predict the dynamic response of the machine-spindle-holder-tool assembly using the receptance coupling substructure analysis technique,where the assembly is divided into three parts:machine-spindle,holder and tool shank,and tool's fluted portion.Impact testing is used to measure the receptance of machine-spindle,the Timoshenko beam model is employed to analyze the dynamics of holder and tool shank,and the finite element method(FEM) is used to calculate the receptance of the tool's fluted portion.The approximation of the fluted portion cross section using an equivalent diameter is also addressed.All the individual receptances are coupled by using substructure method.The predicted assembly receptance is experimentally verified for three different tool overhang lengths.The results also show that the equivalent diameter beam model reaches an acceptable accuracy.The proposed approach is helpful to predict the tool point dynamics rapidly in industry. | ZHANG Jun SCHMITZ Tony ZHAO Wanhua LU Bingheng | 2011 | Chinese Journal of Mechanical Engineering2011，24，3： | 9 |
| 5 | Cryogenic 3D printing of dual-delivery scaffolds for improved bone regeneration with enhanced vascularization显示文摘Three-dimensional(3D)printing has been increasingly employed to produce advanced bone tissue engineering scaffolds with biomimetic structures and matched mechanical strengths,in order to induce improved bone regeneration in defects with a critical size.Given that the successful bone regeneration requires both excellent osteogenesis and vascularization,endowing scaffolds with both strong bone forming ability and favorable angiogenic potential would be highly desirable to induce improved bone regeneration with required vascularization.In this investigation,customized bone tissue engineering scaffolds with balanced osteoconductivity/osteoinductivity were produced via cryogenic 3D printing ofβ-tricalcium phosphate and osteogenic peptide(OP)containing water/poly(lactic-co-glycolic acid)/dichloromethane emulsion inks.The fabricated scaffolds had a hierarchically porous structure and were mechanically comparable to human cancellous bone.Angiogenic peptide(AP)containing collagen I hydrogel was then coated on scaffold surface to further provide scaffolds with angiogenic capability.A sequential release with a quick AP release and a slow but sustained OP release was obtained for the scaffolds.Both rat endothelial cells(ECs)and rat bone marrow derived mesenchymal stem cells(MSCs)showed high viability on scaffolds.Improved in vitro migration and angiogenesis of ECs were obtained for scaffolds delivered with AP while enhanced osteogenic differentiation was observed in scaffolds containing OP.The in vivo results showed that,toward scaffolds containing both AP and OP,the quick release of AP induced obvious angiogenesis in vivo,while the sustained OP release significantly improved the new bone formation.This study provides a facile method to produce dual-delivery scaffolds to achieve multiple functions. | Chong Wang Jiahui Lai Kai Li Shaokui Zhu Bingheng Lu Jia Liu Yujin Tang Yen Wei | 2021 | Bioactive Materials2021，6，1： | 7 |

| 8 | FEATURE EXTRACTION OF BONES AND SKIN BASED ON ULTRASONIC SCANNING显示文摘In the prosthetic socket design, aimed at the high cost and radiation deficiency caused by CT scanning which is a routine technique to obtain the cross-sectional image of the residual limb, a new ultrasonic scanning method is developed to acquire the bones and skin contours of the residual limb. Using a pig fore-leg as the scanning object, an overlapping algorithm is designed to reconstruct the 2D cross-sectional image, the contours of the bone and skin are extracted using edge detection algorithm and the 3D model of the pig fore-leg is reconstructed by using reverse engineering technology. The results of checking the accuracy of the image by scanning a cylinder work pieces show that the extracted contours of the cylinder are quite close to the standard circumference. So it is feasible to get the contours of bones and skin by ultrasonic scanning. The ultrasonic scanning system featuring no radiation and low cost is a kind of new means of cross section scanning for medical images. | Zheng Shuxian Zhao Wanhua Lu Bingheng Zhao Zhao | 2005 | Chinese Journal of Mechanical Engineering2005，18，4： | 3 |
| 9 | Roll-to-roll imprint for high precision grating manufacturing显示文摘In this paper,a novel roll-to-roll imprint process is proposed to fabricate gratings in large area. The key challenges in roll-to-roll imprint process,such as the roller mold preparation,imprint system,misalignment of imprint roller and backup roller,and also the imprint pressure,are investigated. Various gratings with different periods and profiles are obtained by the roll-to-roll process. To calibrate the measuring ability of the self-made grating by imprint,a calibration system is built with a dual-frequency laser interferometer. By the calibration,the self-made gratings can achieve ±4μm accuracy in 45mm measuring distance. | Liu Hongzhong Shi Yongsheng Yin Lei Jiang Weitao Lu Bingheng | 2013 | Engineering Sciences2013，11，1： | 3 |
| 10 | 中国城市中大气分粒级的粒子数浓度与每日死亡率显示文摘[背景]大气颗粒物-9健康结局之间的相关性已在全球范围内广为报道。然而,有关不同粒径颗粒物对健康影响的研究却十分有限。[目的]以中国沈阳为例,探索不同粒径颗粒物的数量浓度(particle number concentrations,PNCs)与每日死亡率之间的关系。[方法]研究时间为2006年12月1日至2008年11月30日,分别收集每日死因别死亡率和直径为0.25~10岬颗粒物的每日PNCs。用基于半泊松回归的广义相加模型来评估PNCs-9死亡率之间的相关性,同时采用自然样条平滑函数校正随时间变化的协变量、长期趋势及季节性趋势。[结果]在研究时间内,归因于非意外的自然死亡、心血管疾病和呼吸系统疾病的平均每日死亡数分别为67、32和7。直径为0.25-0.50gm的颗粒物PNCs与总死亡率和心血管疾病死亡率明显相关,但与呼吸系统疾病死亡率无明显相关性。与冷季相比,暖季里PNCs效应估计值较大,并且效应值随着颗粒物粒径的减小而增加。0.25~0.28p,m、O.35~0.40μm和0.45—0.50gm的颗粒物PNCs每增加1个IQR浓度,与之相关的总死亡风险分别增大2.41%(95%CI:1.23%~3.58%)、1.31%(95%CI:0.52%~2.09%)和0.45%(95%CI:0.04%-0.87%)。校正大气颗粒物和气态污染物的质量浓度后,这种相关性仍然保持稳定。[结论]研究结果提示,直径〈0.5μm的颗粒物可能是空气污染颗粒中导致不良健康影响的最主要成分,并且对健康的不利影响随着颗粒直径的减小而增加。 | Xia Meng Yanjun Ma Renjie Chen Zhijun Zhou Bingheng Chen Haidong Kan 张伊人 汪源 金泰廙 | 2014 | 环境与职业医学2014，31，4： | 2 |
