Description

光固化3D打印多套切片参数的打印执行控制方法及装置
本申请要求于2021年02月05日在中国国家专利局提交的、申请号为202110162368.8、发明名称为“光固化3D打印多套切片参数的打印执行控制方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及3D(3-dimension，三维)打印技术领域，具体涉及光固化3D打印多套切片参数的打印执行控制方法及装置。
背景技术
目前在现有的光固化3D打印中，不同的光敏树脂成型反应曝光时间参数一般采用的是各个光固化整机厂指定树脂品牌的树脂特性参数推荐值，但是如果用户自己选择选配其他品牌树脂时，需要经过多次打印测试才能得出合适的推荐值，此时容易遇到以下问题：选配不同树脂时，在现有技术中需要逐个打印近十个乃至更多个模型并设定不同的阶梯化切片打印参数，才能在最优打印成品中选出相应的最优树脂特性参数，而某些特性树脂，树脂成型反应时间要求特别精准，有时反应时间需要精确到小数点后1位，导致测试工作量巨大，且无法在同一时间看出时间差异引起的成型差异。
技术问题
为了解决上述背景技术中的问题，本发明针对同一个切片里具有多个不同模型掩膜图片及其不同曝光时间参数和图像优化参数的情况，提供两种多套切片参数的光固化3D打印执行控制方法及装置；在处理多个不同模型的切片预处理环节，设定不同参数后得到多套切片打印参数后，可以针对其切片后所生成的，同一个切片里具有多个不同模型掩膜图片及其不同曝光时间参数和图像优化参数的情况，与之相应的，提供两种切实可行的多套切片参数的光固化3D打印执行控制方法。

本发明的实施方式
下面结合附图对本发明实施例作进一步说明。
本申请人同日提交的另一个发明申请，《光固化3D打印模型多套切片打印参数设置方法》中所采用的方法1中用户可根据3D模型的个数对各个模型各自设定模型切片打印参数，能够在打印一批数十个相同模型的同时还能各自设定不同精确密集的阶梯化参数，容易在一个打印批次中选出相同模型中最优效果打印成品并获得相应的树脂特性最优参数及其他最优打印设置参数，同时还能在同一时间观察比较打印成品之间的成型差异；其方法2中用户可根据多个3D模型的不同分组对各组模型各自设定模型切片打印参数，能够在打印一批多套不同模型的同时还能将每套中的多个相同模型各自设定不同的模型切片打印参数，容易在一个打印批次中同时选出各套不同模型的最优效果打印成品并获得相应的树脂特性最优参数及其他最优打印设置参数。
但是,由于其方法1中用户根据3D模型的个数对各个模型各自设定模型切片打印参数；其方法2中用户根据不同分组对各组模型各自设定模型切片打印参数；导致两种方法下其进行切片后，同一个切片里不同模型下的图片的曝光时间参数是各不相同的，因此曝光时间这一参数无法按照上述每个切片下只对应分配一套打印参数的方法来进行打印。
而在目前现有光固化3D打印中，普遍采取的办法是在切片预处理环节,将模型导入切片软件,在设定完成切片打印参数设定完成并进行切片后,每层切片下只对应分配一张层内图像和一套打印参数,包括掩膜图像、曝光时间、平台运动速度、平台运动距离、平台静止时间、灯灭延迟时间等参数；使光固化打印机的控制单元在打印环节只需要按照每层切片中分配好的参数，控制相应执行机 构执行相应的参数，控制LCD屏载入掩膜图像并随着切片的逐层打印来逐一切换层内掩膜图像，控制UV紫外灯点亮并对掩膜图像进行曝光，控制UV紫外灯灭灯延迟等待时间，控制平台驱动电机的运动速度、运动距离、静止时间；或者，控制投影装置载入层内图像打印页参数并对其掩膜图像进行掩膜投影，对液槽内的光敏树脂进行曝光使其固化成型；控制平台驱动电机的运动速度、运动距离、静止时间，控制平台驱动电机的运动速度、运动距离、静止时间。
所以在上述方法1和方法2下，如果还采用目前每层切片下只对应分配一张层内图像和一套打印参数来进行打印，那么方法1和方法2的模型在切片预处理环节，利用模型切片软件进行处理切片后所得到的多套切片打印参数，就没有与之相应的、切实可行的多套切片参数的光固化3D打印执行控制方法。
本发明提供了两种光固化3D打印多套切片参数的打印执行控制方法，在处理多个不同模型的切片预处理环节，设定不同参数后得到多套切片打印参数后，可以针对其切片后所生成的，同一个切片里具有多个不同模型掩膜图片及其不同曝光时间参数和图像优化参数的情况，与之相应的，提供两种切实可行的多套切片参数的光固化3D打印执行控制方法。

图5为同日申请光固化3D打印模型多套切片打印参数设置方法1的实施例1。当用户在选用新的非指定品牌型号的光敏树脂6时,由于不同厂家不同树脂型号之间光敏固化特性不同,且没有统一的适配标准,所以在对某个模型进行大批量模型打印时,需要预先对模型切片打印参数进行调试,在此过程中,以现有技术的做法是需要逐个打印多个模型并设定不同的阶梯化切片打印参数，然后在最优打印成品中选出相应的最优树脂特性参数；但是这种方式测试打印时间过长。
而采用同日申请图2中方法流程图1，则可以如图4所示导入或复制4个相同的打印模型，然后对这4个打印模型设置4套切片打印参数，例如将4个打印模型的曝光时间阶梯化设置为1.0s、2.0s、3.0s、4.0s；使4个打印模型能够一个批次完成打印，在打印结束后，用户再通过比较打印品的打印效果，例如观察各个打印品纹理清晰度、打印表面光滑度、打印完成度、尺寸准确性、打印 品结构强度，从中来选出效果最好的打印模型并以其相对应的切片打印设定参数，来作为本次所用光敏树脂6的最优切片打印参数；这种方法下，一个批次同时完成多个测试模型的打印，有利于节省大量测试打印时间和工作量。
图6为同日申请光固化3D打印模型多套切片打印参数设置方法2的实施例1。当用户需要大批量打印不同模型时,也需要预先对模型切片打印参数进行调试,在此过程中,以现有技术的做法是将每种模型逐个打印近十个乃至更多个模型并设定不同的阶梯化切片打印参数，才能在每种模型的最优打印成品中选出相应的最优树脂特性参数；这种方式测试打印时间更长。
而采用同日申请图3中方法流程图2，则可以如图5所示导入或复制4个两种不同的打印模型，其中每种模型同时打印2个，然后将两种打印模型两两配对分为2组，然后对这2组打印模型设置2组切片打印参数，例如将5组打印模型的曝光时间阶梯化设置为1.0s、2.0s；使2组打印模型能够一个批次完成打印，在打印结束后，用户再通过比较打印品的打印效果，从中来选出效果最好的1组打印模型并以其相对应的切片打印设定参数，来作为本次打印两种模型时所用光敏树脂6的最优切片打印参数；这种方法下，一个批次同时完成多个不同测试模型的打印，有利于节省大量测试打印时间和工作量。
图7为同日申请光固化3D打印模型多套切片打印参数设置方法1的实施例2。如图所示,在图4的基础上，用户通过3D切片预处理软件将4个模型各自设定模型切片打印参数,并进行切片后得到4层切片；由于一般在实际打印中,需要默认或手动指定第一层或开始的数层作为底层切片,底层切片的曝光时间一般为统一的切片打印参数,所以底层切片中一般各层只具有一套切片打印层参数，层内也只有一套图像打印页参数，即同一个切片里只有一个统一的掩膜图片及其曝光时间参数和图像优化参数；
例如，图中只有最下面阴影部分的一层作为底层切片，底层的4个模型共用一张掩膜图片进行曝光，所以4个模型在底层的曝光时间均为5秒；这里取5秒曝光时间是因为一般在实际打印中，底层切片在曝光打印时，对应于图17中成型树脂61处成型的树脂固化成切片时需要附着于成型平台7的底部，所以需要的曝光反应时间略长于非底层切片相互间的光固化附着时间；回到图6中，从下往上第2、3、4层切片为非底层切片，其每层切片的各自有一套切片打印层参数；一般情况下，切片打印层参数包括：成型平台运动速度参数、成型平台运动距离参数、成型平台静止时间参数、光源灯亮时间参数、灯灭延迟时间参数切片层厚参数、或投影亮屏时间参数、或投影熄屏延迟时间参数等涉及到光固化打印设备的执行和运动机构的运动参数；各层切片由于有4个曝光时间参数不同的模型，所以每层切片层内又具有4套层内图像打印页参数；一般情况下，层内图像打印页参数包括：掩膜图像参数、和掩膜图像曝光时间参数、掩膜图像边缘优化设置参数、掩膜图像抗锯齿优化参数、掩膜图像公差补偿参数、掩膜图像均光优化补偿参数、打印支撑设置参数等涉及到掩膜图像相关信息的参数；图中11、21、22、31、41这些数字是3D切片预处理软件生成的层内图像打印页的缓存数据标志位，数字第一位表示所在的层，数字第二位表示层内掩膜图像所在的页；所以在本发明的控制方法中，控制单元1读取缓存数据标志位时能够由此判断执行第几层的切片打印层参数和执行第几页的层内图像打印页参数；
此外模型M1-M4由于在每一层切片中分别曝光1s-4s,所以模型M1在第2层切片中只在页21中曝光1s,在页22-24中通过切换层内图像打印页参数，使图17中LCD屏2中掩膜图像或切换为第2页后，模型M1处的掩膜图像通道21关闭后，在第2层切片中不再曝光，直至下一层；而模型M4在第2层切片中通过切换层内图像打印页参数，使图17中LCD屏2中掩膜图像连续切换4页掩膜图像页后，模型M4处的掩膜图像通道21开启4次，每次曝光时间1s，即控制单元1控制LCD屏2快速切换使每页掩膜图像显示1s,累计进行4次后，模型M4处的掩膜图像实现曝光4s。
图8为同日申请光固化3D打印模型多套切片打印参数设置方法2的实施例2。如图所示,在图5的基础上，用户通过3D切片预处理软件将4个模型分为2组后，将4个模型设定为2组模型切片打印参数,并进行切片后得到4层切片；由于一般在实际打印中,需要默认或手动指定第一层或开始的数层作为底层切片,底层切片的曝光时间一般为统一的切片打印参数,所以底层切片中一般各层只具有一套切片打印层参数，层内也只有一套图像打印页参数，即同一个切片里只有一个统一的掩膜图片及其曝光时间参数和图像优化参数；
例如，图中只有最下面阴影部分的一层作为底层切片，底层的4个模型共用一张掩膜图片进行曝光，所以4个模型在底层的曝光时间均为3秒；这里取3秒曝光时间是因为一般在实际打印中，底层切片在曝光打印时，对应于图17中成型树脂61处成型的树脂固化成切片时需要附着于成型平 台7的底部，所以需要的曝光反应时间略长于非底层切片相互间的光固化附着时间；回到图6中，从下往上第2、3、4层切片为非底层切片，其每层切片的各自有一套切片打印层参数；一般情况下，切片打印层参数包括：成型平台运动速度参数、成型平台运动距离参数、成型平台静止时间参数、光源灯亮时间参数、灯灭延迟时间参数切片层厚参数、或投影亮屏时间参数、或投影熄屏延迟时间参数等涉及到光固化打印设备的执行和运动机构的运动参数；各层切片由于有2组曝光时间参数不同的模型，所以每层切片层内又具有2套层内图像打印页参数；一般情况下，层内图像打印页参数包括：掩膜图像参数、和掩膜图像曝光时间参数、掩膜图像边缘优化设置参数、掩膜图像抗锯齿优化参数、掩膜图像公差补偿参数、掩膜图像均光优化补偿参数、打印支撑设置参数等涉及到掩膜图像相关信息的参数；图中11、21、22、31、41这些数字是3D切片预处理软件生成的层内图像打印页的缓存数据标志位，数字第一位表示所在的层，数字第二位表示层内掩膜图像所在的页；所以在本发明的控制方法中，控制单元1读取缓存数据标志位时能够由此判断执行第几层的切片打印层参数和执行第几页的层内图像打印页参数；
此外模型M1与N1由于在每一层切片中分别曝光1s，M2与N2由于在每一层切片中分别曝光2s,所以模型M1与N1在第2层切片中只在页21中曝光1s,在页22中通过切换层内图像打印页参数，使图17中LCD屏2中掩膜图像切换为第2页后，模型M1与N1处的掩膜图像通道21关闭后，在第2层切片中不再曝光，直至下一层；而模型M2与N2在第2层切片中通过切换层内图像打印页参数，使图17中LCD屏2中掩膜图像连续切换2页掩膜图像页后，模型M2与N2处的掩膜图像通道21开启2次，每次曝光时间2s，即控制单元1控制LCD屏2快速切换使每页掩膜图像显示1s,累计进行2次后，模型M2与N2处的掩膜图像实现曝光2s。
图9为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例1。如图所示,该图对应于图2采用其方法进行切片后生成如图所示的一层模型切片，切片的厚度对应为图17中每次成型的成型树脂61的固化后的薄片厚度；图中4个白色方框中的不同时间，表示为每层切片打印时四个模型处各自的总的曝光时长。
图10为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例2。在图8展示的切片中，具有如本图所示的4页掩膜图片，图中阴影部分为层内每页掩膜图像不透光部分，图中第1页4个白色方框中的时间，对应于图6中的页21、页31或页41，在曝光如本图所示的第1页掩膜图像时，4个模型的掩膜图像通道21全部开启，曝光时间为1s；所谓的掩膜图像通道21全部开启，指的是LCD屏2中切换并载入本页掩膜页图像后，M1、M2、M3、M4四处图形位置的掩膜图像通道21的像素灰度全部为255，以实现透光和曝光。
图11为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例3。如图所示,图中第2页4个白色方框中的时间，对应于图6中的页22、页32或页42，在曝光如本图所示的第2页掩膜图像时，模型M1处的掩膜图像通道21全部关闭，关闭时间为1s；模型M2、M3、M4处的掩膜图像通道21全部开启，曝光时间也为1s；所谓的掩膜图像通道21全部开启，指的是LCD屏2中切换并载入本页掩膜页图像后，M2、M3、M4四处图形位置的掩膜图像通道21的像素灰度全部为255，实现透光和曝光；所谓的掩膜图像通道21关闭，指的是LCD屏2中切换并载入本页掩膜页图像后，M1处图形位置的掩膜图像通道21的像素灰度全部为0，以实现停止透光和曝光。
图12为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例4。如图所示,图中第3页4个白色方框中的时间，对应于图6中的页23、页33或页43，在曝光如本图所示的第3页掩膜图像时，模型M1、M2处的掩膜图像通道21全部关闭，关闭时间为1s；模型M3、M4处的掩膜图像通道21全部开启，曝光时间也为1s；所谓的掩膜图像通道21全部开启，指的是LCD屏2中切换并载入本页掩膜页图像后，M3、M4四处图形位置的掩膜图像通道21的像素灰度全部为255，实现透光和曝光；所谓的掩膜图像通道21关闭，指的是LCD屏2中切换并载入本页掩膜页图像后，M1、M2处图形位置的掩膜图像通道21的像素灰度全部为0，以实现停止透光和曝光。
图13为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例5。如图所示,该图对应于图3采用其方法进行切片后生成如图所示的一层模型切片，切片的厚度对应为图17中每次成型的成型树脂61的固化后的薄片厚度；图中4个白色方框中的不同时间，表示为每层切片打印时四个模型处各自的总的曝光时长。
图14为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例6。如图所示,该图在图12的切片基础上显示了第1页掩膜图像，图中阴影部分为层内第1页掩膜图像不透光部分，图中第1页4个白色方框部分为透光部分；由于本图的切片是经过图3的方法的预处理，M1和N1 为一组，M2和N2为一组，所以在M1和N1、M2和N2在每一页上的曝光时间是相同的，即同时曝光，或同时不曝光。
图15为本发明两种光固化3D打印多套切片参数的打印执行控制方法实施例7。如图所示,图中第1页4个白色方框中的时间，对应于图7中的页21、页31或页41，在曝光如本图所示的第1页掩膜图像时，4个模型的掩膜图像通道21全部开启，曝光时间为1s；所谓的掩膜图像通道21全部开启，指的是LCD屏2中切换并载入本页掩膜页图像后，M1、N1、M2、N2四处图形位置的掩膜图像通道21的像素灰度全部为255，以实现透光和曝光；此外最底层垂直投影虚框表示的是下一层切片，可忽略。

图18为本发明光固化3D打印多套切片参数的打印执行控制装置1的实施例2。如图所示,在图16的基础上，所述控制单元1控制LCD屏2切换并载入如图9中的第1页掩膜图像时，则4个模型的掩膜图像通道21全部开启，M1、M2、M3、M4四处图形位置的掩膜图像通道21的像素灰度全部为255；光源3发出的紫外光和可见光透过LCD屏2中的掩膜图像通道21对光敏树脂6照射，使其光固化反应成型，形成一层一层的成型树脂61；所述成型平台7用于在固化成型过程中附着固化成型后的光敏树脂6使其不断提升生长直至3D打印完成。
图19为本发明光固化3D打印多套切片参数的打印执行控制装置2的实施例1。如图所示，本图中采用的是上升投影式光固化3D打印机。其打印执行控制装置,包括：控制单元1、存储单元11、投影装置230、电机4、升降柱41、液槽5、底膜51、光敏树脂6、成型平台7、底座8；所述控制单元1、存储单元11、投影装置230、液槽5设置连接于底座8；所述电机4连接成型平台7；所述升降柱41固定连接于底座8；所述电机4安装于升降柱41实现电驱动升降并带动成型平台7随其抬升或下降；所述底膜51设置于液槽5底部用于透光；所述液槽5内盛放光敏树脂6液体；所述控制单元1电连接存储单元11、投影装置230、电机4；所述存储单元11存储3D打印切片软件对3D模型进行切片后生成切片打印层参数和层内图像打印页参数；所述控制单元1读取存储单元11中的切片打印层参数和层内图像打印页参数；所述控制单元1控制投影装置230载入层内图像打印页参数后亮屏并根据曝光时间参数对其进行掩膜投影，以及控制投影装置230的熄屏；所述控制单元1控制电机4驱动成型平台7按切片打印层参数进行升降运动；所述投影装置230发出经过图像掩膜的紫外光及可见光投影透过底膜51对液槽5内的光敏树脂6进行曝光照射使其固化成型；所述成型平台7用于在固化成型过程中附着固化成型后的光敏树脂6使其不断提升生长直至3D打印完成；所述投影装置230采用LCD式投影仪、或基于DMD数字微镜技术的DLP投影仪。
图20为本发明光固化3D打印多套切片参数的打印执行控制装置2的实施例2。如图所示，在图19的基础上，所述控制单元1控制投影装置230切换并载入如图9中的第1页掩膜图像，在亮屏并向液槽5中的光敏树脂6投影后，投影装置230发出经过图像掩膜的紫外光及可见光投影透过底膜51对液槽5内的光敏树脂6进行曝光照射使其固化成型，形成一层一层的成型树脂61；由于模型M1、M2、M3、M4四处图形的中间位置是不进行固化打印的，所以侧视视角下，本图中两个投影阴影的中间部分不产生紫外光及可见光投影；所述成型平台7用于在固化成型过程中附着固化成型后的光敏树脂6使其不断提升生长直至3D打印完成。
图21为本发明光固化3D打印多套切片参数的打印执行控制装置1的实施例3。如图所示，本图中采用的是下沉式LCD光固化3D打印机。其打印执行控制装置组成部分相比图17和图18减少了底膜51，由于是采用的是下沉式打印，所以光源3发出的紫外光和可见光透过LCD屏2中的掩膜图像通道21后，无需透过底膜51，即可直接照射光敏树脂6的液面，使相应位置掩膜图像位置的树脂液面光固化反应成型，形成一层一层的成型树脂61；所述成型平台7用于在固化成型过程中附着固化成型后的光敏树脂6使其不断下沉生长直至3D打印完成；采用本实施例的下沉式LCD光固化3D打印机时，由于其无需像上升式LCD光固化3D打印一样，需要将每次固化后的底部成型树脂进行脱膜，所以也就无需使成型平台7带动成型切片层进行往复运动；所以对应的参数L1的运动距离为切片层厚，L2的运动距离为0，L3的运动距离可以设置为20毫米这样的较大参数以利于拔膜取件。
图22为本发明光固化3D打印多套切片参数的打印执行控制装置2的实施例3。如图所示，本图中采用的是下沉投影式光固化3D打印机。其打印执行控制装置组成部分相比图19和图20减少了底膜51，由于是采用的是下沉式打印，所以投影装置230发出经过图像掩膜的紫外光及可见光投影无需透过底膜51，即可直接照射光敏树脂6的液面，使相应位置掩膜图像位置的树脂液面光固化反应成型，形成一层一层的成型树脂61；所述成型平台7用于在固化成型过程中附着固化成型后的光敏树脂6使其不断下沉生长直至3D打印完成；采用本实施例的下沉投影式光固化3D打印机时，由于其无需像上升投影式光固化3D打印一样，需要将每次固化后的底部成型树脂进行脱膜，所以也就无需使成型平台7带动成型切片层进行往复运动；所以对应的参数L1的运动距离为切片层厚，L2的运动距离为0，L3的运动距离可以设置为20毫米这样的较大参数以利于拔膜取件。
