Abstract ：
In this study, highly loaded tin oxide-based (SnO2-based) porous electrodes were prepared by digital light processing (DLP) 3D printing technology. Firstly, the SnO2 light-cured slurry was prepared. The curing process and heat treatment process were analyzed and optimized. Then the best process parameters were obtained. Antimony oxide (Sb2O3) was selected as the conductive agent to improve the electrical con-ductivity of the SnO2-based electrode. Through the characterization of resistivity, SEM and XRD, the op-timum doping amount of conductive agent Sb2O3 was determined to be 6 wt. %. Three kinds of porous electrodes with different shapes were prepared by DLP 3D printing, and the printing accuracy and me-chanical properties were characterized. The results showed that the forming dimension error was about 1.7 % in the X and Y direction, 2.3 % in the Z direction. And the average compressive strength was 18.1 MPa, which effectively ensured the shape integrity and mechanical stability of the printed parts. Then the electrochemical properties of DLP 3D printed SnO2-based electrode and conventional coated electrode were tested and compared. The results showed that the 3D printed porous electrode showed lower charge transfer impedance and higher ion diffusion efficiency, and the maximum charge transfer impedance could be reduced to 1/25 of the traditional electrode; At the same time, it showed better cycle performance and rate performance, and the capacity retention of the 3D printed porous electrode could be improved by about 29.0 % compared with the traditional electrode. This work shows that high-performance high-load porous electrodes can be accurately prepared by DLP 3D printing, which provides a new strategy for the future development of high-load thick electrodes.

Abstract ：
Porous tin oxide-based (SnO2-based) ceramics with lattice structures were prepared by digital light processing (DLP) 3D printing technology. A 57 wt% SnO2-based DLP slurry was prepared by rheological experiments. By optimizing the exposure time, the DLP process for preparing SnO2 based ceramics had better molding accuracy. The printing size error could be controlled at about 1.8%. The degreasing and sintering curves were obtained by thermogravimetric-differential scanning calorimetry (TG-DSC) analysis, and the SnO2-based porous ceramics with porosity of 50%-71% were prepared. The SnO2-based ceramics with high densification could be obtained by sintering at 1300 degrees C for 2 h. The relative density of printed SnO2-based ceramics was about 92%. In this paper, zinc oxide (ZnO) was selected as a sintering additive to promote the densification of SnO2 ceramics. According to the characterization methods of scanning electron microscopy(SEM), X-ray diffraction(XRD), Energy dispersive spectrometer (EDS) and relative density, the optimum doping amount of ZnO was 9 wt%. The influence of pore structure on compressive strength was analyzed by finite element simulation and compressive test. The compressive strength of porous ceramics could be reduced from 1.56 MPa to 0.27 MPa by controlling the porosity of the porous lattice from 50% to 71%. The compressive strength of the solid block was 160 MPa. In this study, the porous SnO2-based ceramics prepared can be used in porous electrodes, lithium-ion batteries, super capacitors, catalysts, sensors and other fields in the future.

Abstract ：
An implant template with great precision is significantly critical for clinical application. Currently, the application of an immediate implant remains limited by the deviations between the planned and actual achieved positions and long periods required for preparation of implant templates. Material Extrusion (MEX), as one kind of 3D printing method, is well known for its low cost and easy operation. However, the accuracy of the implant template printed by MEX has not been fully researched. To investigate the accuracy and feasibility of in vitro computer-guided surgery assisted with a MEX printed template, unidentified plaster samples missing a maxillary molar are digitalized. Mimics software (Materialise, Leuven, Belgium) is used for preoperative design. Surgical templates are fabricated by a MEX 3D printer (Lingtong III, Beijing SHINO, Beijing, China). Postoperative CBCT data are obtained after surgical template placement. The differences in positions of X, Y, Z, and dXYZ as well as angulations between the placed and the designed template are measured on labiolingual and mesiodistal planes. The deviations of the planned and the actual outcome in each dimension are observed and analyzed. Data from different samples indicate that the mean deviation of the angle measures approximately 3.640 degrees. For position deviation, the maximum deviation is found in the z-direction and the mean deviation is about 0.365 +/- 0.136 mm. The mean deviation of space Euclidean distance dXYZ is approximately 0.537 +/- 0.123 mm. Implant templates fabricated by MEX present a relatively high accuracy for tooth-supported guide implantation.

Abstract ：
The fabrication of high-precision scaffolds with excellent biocompatibility for tissue engineering has become a research hotspot. Two-photon polymerization (TPP) can break the optical diffraction limit and is used to fabricate high-resolution three-dimensional (3D) microstructures. In this study, the biological properties, and machinability of photosensitive gelatin methacrylate (GelMA) hydrogel solutions are investigated, and the biocompatibility of 3D scaffolds using a photosensitive GelMA hydrogel solution fabricated by TPP is also evaluated. The biological properties of photosensitive GelMA hydrogel solutions are evaluated by analyzing their cytotoxicity, swelling ratio, and degradation ratio. The experimental results indicate that: (1) photosensitive GelMA hydrogel solutions with remarkable biological properties and processability are suitable for cell attachment. (2) a micro/nano 3D printed scaffold with good biocompatibility is fabricated using a laser scanning speed of 150 mu m/s, laser power of 7.8 mW, layer distance of 150 nm and a photosensitive GelMA hydrogel solution with a concentration of 12% (w/v). Micro/nano additive manufacturing will have broad application prospects in the tissue engineering field.

Abstract ：
3D printing technology was introduced into the manufacturing of ceramic components. To obtain a new light-weight multifunctional structure with novel structure and excellent performance, and promote the deep com-bination of additive manufacturing and optimization design, ZrO2(3Y)/Al2O3 hollow lattice structure ceramics with two kinds of high precision and different porosity were prepared by vat photopolymerization in this paper, and the process optimization, microstructure evolution, and performance were studied. The hollow lattice structure with good molding accuracy and porosity of 35 %-55 % was prepared by component design, opti-mization of slurry, degreasing, and sintering process, which effectively avoided the ceramic cracking and collapse caused by resin volatilization. When the Al2O3 content was 6 wt%, dense ZrO2(3Y)/Al2O3 ceramics with grain refinement, excellent microhardness, and fracture toughness were obtained. The relationship between lattice structure and compressive strength was analyzed by simulation and compressive test. The results show that the compressive strength of the two hollow lattice structures decreases with the increase of porosity. The maximum compressive strength of 35 %-face-centered cubic (FCC) hollow lattice structure is 326 MPa, which is significantly higher than that of body-centered cubic (BCC) structure (240 MPa) with the same porosity. The hollow lattice ceramic structure with good comprehensive performance and lightweight will lay a foundation for the application of industrial heat insulation, high temperature catalysis, and purification carrier in the future.
