Micro-model 3D printing forming method

The invention relates to a micro-model 3D printing forming method, 3D printing forming is carried out by utilizing a stereo lithography technology, a fence is printed around a target micro-model synchronously with the micro-model, the fence is an independent whole surrounding the micro-model, and the distance between the fence and the micro-model is kept between 0.3 mm and 0.5 mm. Due to the fact that the fence is synchronously printed on the periphery of the micro-model, the fence can prevent the impact of printing material fluctuation caused when the micro-model moves on each layer of slices of the model. Therefore, the 3D printing success rate of the micro-model can be remarkably improved. 本发明涉及一种微模型3D打印成型方法，利用立体光刻技术进行3D打印成型，在目标微模型的周围与所述微模型同步打印出围栏，所述围栏是围绕在所述微模型周围的单独整体，所述围栏与所述微模型之间的距离保持在0.3mm~0.5mm。由于在微模型的周围同步打印出了围栏，围栏能够阻挡微模型移动时引发的打印物料波动对模型每层切片的冲击。这能够显著提高微模型的3D打印成功率。
