本研究致力於開發一套具有多雷射模組的高速3D列印技術，有別於其他單點掃描式的雷射燒結3D列印機台，不需使雷射光斑在粉體表面不斷來回掃描，多雷射模組於單次的掃描行程(Single-Pass)內，即可將目標區域內的圖案掃描成型，多雷射模組上的雷射數目越多，代表單次行程內可提供的成型範圍越大，藉此達到高速3D列印的目的。
初期先以機台改良設計為主，將實驗室先前研究中所使用的噴墨列印機台改良，將噴印模組移除後新增多雷射模組以及其他的硬體設施，同時針對原機台上存在的缺陷進行改善，以符合多雷射模組的高速列印製程。接著將改良機台相關的軟體、韌體，使機構能依照製程上的設計運動。
完成機台相關的所有改良之後，將會進行列印製程的參數分析。製程選材使用熱塑性聚氨酯(Thermoplastic polyurethanes, TPU)，為常見的彈性材料且應用相當廣泛，根據該材料的熱性值分析結果訂定出製程中的粉槽持溫溫度，同時也對於預熱熱源的選用進行討論。最後以預熱溫度與能量密度為變數進行材料燒結測試，根據量測所得的單層厚度做為製程參數調控的參考。

This research is dedicated to the development of a high-speed 3D printing technology with multiple laser modules, which is different from single point scanning laser sintered 3D printing machines. Multiple laser modules can scan the pattern in the target area within a single scan stroke (single pass). The more lasers on the multi laser module, the bigger molding range can be provided in a single stroke, so as to achieve the purpose of high-speed 3D printing.
In the early stage, the improved design of the machine was the main focus. Improve the inkjet printer used in the laboratory's previous research, and add multiple laser modules and other hardware devices after removing the inkjet module. At the same time, the defects in the original machine are improved to meet the high speed printing process of multiple laser modules. Then the software and firmware related to the machine will be improved so that the mechanism can move in accordance with the design in the process.
After completing all the improvements related to the machine, the parameter analysis of the printing process will be performed. Thermoplastic polyurethanes are used as materials for the process, which are common elastic materials and are widely used. According to the thermal value analysis result of the material, the holding temperature of the powder tank in the manufacturing process is determined. At the same time, the selection of the preheating heat source is discussed. Finally, the material sintering test is carried out with the preheating temperature and energy density as variables, and the single layer thickness obtained according to the measurement is used as a reference for controlling the process parameters.
