Abstract

This research aims to study the fabrication of electronic devices using pellet extrusion 3D printing with composite material. The process employed a polymer-based composite material that incorporated a substantial amount of barium titanate powder, reaching 80 wt.%. A thorough examination was conducted to understand the various factors influencing the printed components, using a design of experiments (DOE) approach. This method identifies the optimal printing parameters for a Custom Fused Granular Fabrication printer, such as layer height (0.32), barrel temperature (240°C), flow rate (500), and printing speed (2 mm/s). The dielectric constant of the polylactic acid - barium titanate composite reached 8.47 and a loss tangent of 0.099 in the X-band, making it suitable for applications involving high frequencies with a lower cost process and using a more sustainable polymer.

3D打印参数对熔融颗粒法制备聚乳酸/钛酸钡压电复合材料介电常数影响的研究

本研究旨在研究复合材料颗粒挤压3D打印制造电子器件。该工艺采用了一种聚合物基复合材料，其中加入了大量的钛酸钡粉末，达到80 wt.%。使用实验设计（DOE）方法进行了彻底的检查，以了解影响打印组件的各种因素。该方法确定了自定义熔融颗粒制造打印机的最佳打印参数，例如层高（0.32），桶温（240°C），流速（500）和打印速度（2 mm/s）。聚乳酸-钛酸钡复合材料在x波段的介电常数达到8.47，损耗正切为0.099，使其适合于涉及高频的应用，成本更低，使用更可持续的聚合物。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
