Dual scanner three-dimensional printer using selective laser sintering

The invention discloses a dual scanner three-dimensional printer using selective laser sintering. More specifically, the double-scanner three-dimensional printer using selective laser sintering is applicable to double scanners and can greatly shorten the tact time of a three-dimensional structure. When the double-scanner three-dimensional printer using selective laser sintering is applicable to double scanners, the irradiation range of each scanner can cover the whole forming bed under the condition that the scanners do not interfere with each other, the production cost is reduced by using one flat-field focus lens together, and the double-scanner three-dimensional printer using selective laser sintering has many advantages such as efficient configuration of the scanners. 本发明揭示一种利用选择性激光烧结的双扫描器三维打印机，更具体地说，该利用选择性激光烧结的双扫描器三维打印机适用双扫描器而能够大幅缩短三维结构物的生产节拍时间(tact time)，适用双扫描器时能在互不干涉的情形下让各扫描器的照射范围涵盖全体成型床，共同使用一个平场聚焦镜而得以降低生产成本并且诸如高效配置扫描器等发挥出很多优势。
