Description

一种 3D打印机打印中断后恢复打印的方法
技术领域
本发明涉及 3D打印机领域, 尤其涉及一种 3D打印机打印中断后恢复打印的方法。 背景技术
3D打印机, 即快速成型技术的一种机器, 它是一种以数字模型文件为基础, 运用粉末状 金属或塑料等可粘合材料, 通过逐层打印的方式来构造物体的技术。 过去其常在模具制造、 工业设计等领域被用于制造模型, 现正逐渐用于一些产品的直接制造。
现在主流的 3D打印技术主要包括四种: 光固化成型 (SLA), 三维粉末粘接 (3DP), 选 择性激光烧结 (SLS ), 熔融沉积快速成型 (FDM)。
熔融沉积快速成型 (FDM) 又叫熔丝沉积, 它是将丝状热熔性材料加热融化, 通过带有 一个微细喷嘴的喷头挤喷出来。工作时,先确定各层间距,计算机对三维电脑模型进行切片, 生成路径, 然后在计算机控制下喷头按路径移动出料, 热熔材料粘结在工作台上或前一层已 固化的层面上, 每固化一层工作台下移一个层间距, 如此反复逐层制作, 直至最后一层, 通 过材料的层层堆积形成最终成品。
但是 FDM技术普遍存在一个问题, 就是料丝在打印中必须不间断的供料, 而 FDM成型 时间普遍较长, 并且如果中间出现各种原因 (料丝缠绕,温度变化甚至系统故障)造成打印中断, 则之前形成部分的模型只能报废, 因此造成材料的大量浪费。
发明内容
为克服现有技术中的不足, 本发明的目的在于提供一种 3D打印机打印中断后恢复打印 的方法, 该方法可以解决打印中断后模型只能报废, 造成材料的大量浪费的问题。
为实现上述目的, 本发明采用以下技术方案:
一种 3D打印机打印中断后恢复打印的方法,所述 3D打印机设有打印中断后恢复打印的 控制系统, 所述控制系统包括工作状态采集模块、 打印中断判定模块、 位置采集模块、 存储 模块和控制模块;
所述打印中断后恢复打印的方法包括以下步骤:
1 ) 所述工作状态采集模块时刻采集 3D打印机的工作状态信息, 并将工作状态信息发送 至打印中断判定模块;
2)所述打印中断判定模块对工作状态信息进行判定, 若打印中断判定模块判定打印机处 于打印中断状态, 打印中断判定模块则将打印机处于打印中断状态信息发送至控制模块; 3 ) 所述控制模块根据打印中断状态信息向位置采集模块发出位置信息采集指令;
4) 所述位置采集模块收到位置信息采集指令后, 采集 3D打印机的工作台打印中断时在 Z轴上的高度位置和 3D打印机的熔丝挤出头打印中断时在 X-Y平面内的位置, 并形成位置 信息后存储于存储模块中;
5) 所述控制模块接收用户的恢复打印指令后, 调用存储模块中的位置信息, 并控制 3D 打印机的工作台驱动单元将所述工作台驱动至打印中断时在 Z轴上的高度位置, 同时, 控制 3D打印机的熔丝挤出头驱动单元将所述熔丝挤出头驱动至打印中断时在 X-Y平面内的位置; 之后, 3D打印机恢复打印。
所述步骤 2) 中打印中断状态包括 3D打印机的熔丝挤出头断料、 3D打印机温度超过限 值出现故障而导致的打印中断。
本发明采用以上技术方案, 当 3D打印机出现打印中断时, 通过位置采集模块采集 3D打 印机的工作台打印中断时在 Z轴上的高度位置和 3D打印机的熔丝挤出头打印中断时在 X-Y 平面内的位置, 当用户要恢复打印时, 控制模块可以根据位置采集模块采集的信息, 控制 3D 打印机的工作台驱动单元将所述工作台驱动至打印中断时在 Z轴上的高度位置, 同时, 控制 3D打印机的熔丝挤出头驱动单元将所述熔丝挤出头驱动至打印中断时在 X-Y平面内的位置, 从而实现, 3D打印机中断后的继续打印。本发明解决了打印中断后模型只能报废, 造成材料 的大量浪费的问题, 降低了生产成本。
