Description

光固化3D打印模型多套切片打印参数设置方法
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202110162372.4、发明名称为“光固化3D打印模型多套切片打印参数设置方法”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打印模型多套切片打印参数设置方法。
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：1、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，这种方式测试打印时间过长；2、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；
其次，在现有的光固化3D打印中，打印模型的切片一般都是按照所设定的统一层厚进行切片，在遇到打印模型外观比较光滑完整时，可以以较厚的模型切片进行打印，来提高打印速度；在遇到打印模型外观存在较小的特征细节时，需要以较薄的模型切片进行打印，来保证细节光滑度；此时容易遇到以下问题：1、打印模型外观大部分较光滑的时如果还同时存在几处较小的特征细节时，如果采用较厚的层厚统一进行切片时，几处较小的特征细节打印后容易细节粗糙，光滑度差；2、打印模型外观大部分较光滑的时如果还同时存在几处较小的特征细节时，如果采用较薄的层厚统一进行切片时，则特征细节以外的部分就会耗费大量打印时间；
此外，在现有的光固化3D打印中，模型切片一般都是单层切片图像整体单次曝光，且整个打印过程中，成型平台运动策略较简单，直接以固定的速度进行抬升或者下降，以上做法可以满足基础的打印需求，但是容易遇到以下问题：1、切片图层面积变化较大的模型，如果打印时使用较低的抬升速度，大面积和极小区域的打印成功率会提升，但是整体打印时间会变长很多；如果整个打印过程采用较高的抬升速度，则可以缩短模型整体打印时间，但是面积大的切片图像或者面积极小的切片图像，因为较大脱膜速度会导致瞬间脱膜力增大以及瞬间脱膜的震动容易导致打印失败；2、大面积的图层单次整体曝光，树脂反应散发的热量大，容易导致树脂产生活性变高的性能变化，进而造成过度反应；同时产生的应力也大，例如处在横截面面积产生突变的上下两个图层，由于大面积和小面积图层固化时产生的应力不一样，在过渡阶段，容易造成变形。
技术问题
为了解决上述背景技术中的问题，本发明提供了四种光固化3D打印模型多套切片打印参数设置方法，可以针对多套打印模型不同的打印要求或不同的结构特点，通过设置多套切片打印参数使打印模型在同一时段内可以按照不同打印参数，使树脂进行不同时间的曝光或者使成型平台按照不同速度来运动，从而达成更好的打印效果。

图5为本发明光固化3D打印模型多套切片打印参数设置方法实施例1。当在选用新的非指定品牌型号的光敏树脂时，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，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。
而采用本发明的方法1，则可以如图5所示导入或复制10个相同的打印模型，然后对这10个打印模型设置10套切片打印参数，例如将10个打印模型的曝光时间阶梯化设置为0.5s、1.0s、1.5s、2.0s、2.5s、3.0s、3.5s、4.0s、4.5s、5.0s；使10个打印模型能够一个批次完成打印，在打印结束后，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的最优切片打印参数。
同样，在选用某些高精度反应的光敏树脂时，由于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的时候，采用本发明的方法1，则可以如图导入或复制10个相同的打印模型，然后对这10个打印模型设置10套切片打印参数，例如将M1-M10的10个打印模型的曝光时间阶梯化设置为2.1s、2.2s、2.3s、2.4s、2.5s、2.6s、2.7s、2.8s、2.9s、3.0s；使10个打印模型能够一个批次完成打印，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的最优参数；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为本发明光固化3D打印模型多套切片打印参数设置方法实施例2。当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。
而采用本发明的方法2，则可以如图6所示导入或复制10个两种不同的打印模型，其中每种模型同时打印5个，然后将两种打印模型两两配对分为5组，然后对这5组打印模型设置5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0.5s、1.0s、1.5s、2.0s、2.5s；使5组打印模型能够一个批次完成打印，在打印结束后，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为本发明光固化3D打印模型多套切片打印参数设置方法实施例3。当在打印某些外观细节丰富程度不一致的手办、公仔、人偶、机甲、兵人等模型时，常常会遇到模型头部特征细节较为丰富的，而躯体部分细节特征较少的情况，在此过程中，以现有的技术做法是将模型设定统一层厚进行切片；在对打印效果要求不高的情况下将模型以较厚的模型切片进行打印，例如切片层厚设定为0.1mm，从而牺牲打印精确度提高打印速度；在对打印效果要求较高的情况下将模型以较薄的模型切片进行打印，例如切片层厚设定为0.025mm，从而耗费更长的打印时间来提高打印精确度和打印效果。
而采用本发明的方法3，则可以如图7所示导入1个头部特征细节较为丰富的，而躯体部分细节特征较少的人偶打印模型，然后选择在人偶打印模型的颈部位置在Z轴上以X1Y1Z1平面按高度将人偶打印模型划分为H1和H2区域；由于H2区域内人偶打印模型的头部特征细节较多，H1区域内人偶打印模型的身躯特征细节较少；因此可以将H2区域内人偶打印模型的切片厚度设定为0.025mm，将H1区域内人偶打印模型的切片厚度设定为0.1mm；所以完成打印后，人偶打印品模型头部能够纹理清晰、表面光滑、尺寸准确；而人偶打印品模型身躯部分虽然切片层厚较厚，但由于特征细节少，其纹理清晰度稍低、表面光滑度稍差的负面效果却不易看出；这种方法下，既有利于节省总的打印时间，又能够使模型的总体打印效果良好。
此外，这种方法下，如果同时导入多个相同的人偶打印模型，那么在保证模型保持一致高度的摆放情况下，仍旧可以在人偶打印模型的颈部位置在Z轴上以X1Y1Z1平面按高度将多个人偶打印模型统一划分为H1和H2区域；再将H2区域内多个人偶打印模型的切片厚度设定为0.025mm，将H1区域内多个人偶打印模型的切片厚度设定为0.1mm；更有利于节省总的打印时间，又能够使模型的多个人偶打印模型保证良好的打印效果。
图8为本发明光固化3D打印模型多套切片打印参数设置方法实施例4。当在打印某些横截面变化较大如金字塔、轮轴等模型时，常常会遇到打印模型横截面积逐渐增大，或者打印模型横截面积大小出现交替变化的情况，在此过程中，以现有的技术做法是将模型设定为统一层厚进行切片，设定统一的曝光时间参数，然后使成型平台按照设定的统一运动速度进行抬升或下降，再对各层切片图像进行整体单次曝光，从而完成光固化打印；但是容易遇到以下问题：1、在打印横截面积由小到大连续变化较大的模型时；成型平台使用统一的较低抬升或下降速度时，模型打印成功率会提升，但是会耗费更长的打印时间；成型平台使用较高的抬升或下降速度时，模型总体打印时间会缩短，但是成型树脂脱膜时，瞬间脱膜力较大且还会导致脱模瞬间成型平台产生震动致使撕裂，尤其是模型横截面积较大的位置脱膜力过大在打印时更容易被撕裂；2、在打印横截面积由小到大突变变化较大的模型时；模型存在大面积切片图像和小面积切片图像相结合的情形，此时大面积切片图像的曝光时间被迫与小面积切片图像的曝光时间相一致，所以大面积切片图像会被过度曝光，因此结合部处大面积切片图像和小面积切片图像固化时产生的应力也会不一样，所以结合部处固化时容易出现形变。
而采用本发明的方法4，则可以如图8所示导入1个横截面积变化较大轮轴打印模型，然后根据模型的横截面积变化情况设定三个横截面面积比较参数；例如，如果S1面积为50平方毫米、S2面积为100平方毫米、S3面积为150平方毫米，那么可以设定第1个比较范围为0-60平方毫米、第2个比较范围为60-120平方毫米、第3个比较范围为120-180平方毫米；相对应的范围1内对应设定第1套模型切片打印参数、范围2内对应设定第2套模型切片打印参数、范围3内对应设定第3套模型切片打印参数；
所以进行光固化打印时，当打印下部凸台时，S2面积处于范围2内，光固化机执行第2套模型切片打印参数，例如曝光时间2s、成型平台抬升的运动速度30mm/min、成型平台抬升距离8mm、 成型平台下降速度80mm/min；当打印中部圆轴时，S1面积处于范围1内，光固化机执行第1套模型切片打印参数，例如曝光时间2s、成型平台抬升速度40mm/min、成型平台抬升距离8mm、成型平台下降速度80mm/min；当打印上部圆形凸台时，S3面积处于范围3内，光固化机执行第3套模型切片打印参数，例如曝光时间2s、成型平台抬升速度20mm/min、成型平台抬升距离8mm、成型平台下降速度80mm/min；
这种方法下，如图8所示上部圆形凸台与中部圆轴的结合部处，中部圆轴与下部圆形凸台的结合部处，由于上下大小切片各自采用了合适的模型切片打印参数，所以快慢相宜的平台运动速度能使模型总体打印时间缩短；脱模速度也能针对不同横截面积来调整执行，能够尽量避免脱膜速度过大及震动带来的打印失败；不同横截面积的切片采用各自适用的曝光时间也能避免切片图像过度曝光导致的打印变形。
此外，这种方法下，如果同时导入多个打印模型，那么按照同一高度平面上的多个模型横截面积之和，即同一切片内多个模型图像面积之和作为比较标准，依旧可以将多个打印模型整体划分为不同切片参数设定范围，然后在各自范围内单独设定模型切片打印参数；例如如果同时打印4个图8所示的轮轴，S1面积为50平方毫米、S2面积为100平方毫米、S3面积为150平方毫米，那么可以设定第1个比较范围为0-240平方毫米、第2个比较范围为240-480平方毫米、第3个比较范围为480-720平方毫米；然后在范围1内对应设定第1套模型切片打印参数、范围2内对应设定第2套模型切片打印参数、范围3内对应设定第3套模型切片打印参数；所以进行光固化打印时，当打印下部凸台时，四个S2面积之和处于范围2内，光固化机执行第2套模型切片打印参数；当打印中部圆轴时，四个S1面积之和处于范围1内，光固化机执行第1套模型切片打印参数；当打印上部圆形凸台时，四个S3面积之和处于范围3内，光固化机执行第3套模型切片打印参数。
所以本发明方法4中能够在打印一批一个或多个模型的时候，根据3D模型结构特点将模型按不同预设横截面面积划分为不同切片参数设定范围，容易在遇到模型上下形状截面积突变的情形下，根据不同预设横截面面积触发标准，自动切换3D打印机的曝光时间和成型平台运动速度，使总的模型打印时间缩短，使总体模型打印效果增强。
图9为本发明光固化3D打印模型多套切片打印参数设置方法实施例5。如图所示，基于方法1取4个模型为例进行说明，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，所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；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；模型切片打印参数实际包括了切片打印层参数和层内图像打印页参数这两类参数；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等数字是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；
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，使光固化打印设备的LCD屏中掩膜图像切换为第2页后，模型M1处的掩膜图像通道关闭后，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，使光固化打印设备的LCD屏中掩膜图像连续切换4页掩膜图像页后，模型M4处的掩膜图像通道开启4次，每次曝光时间1s，即LCD屏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10为本发明光固化3D打印模型多套切片打印参数设置方法实施例6。如图所示，基于方法2取2组模型为例进行说明，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，所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；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；模型切片打印参数实际包括了切片打印层参数和层内图像打印页参数这两类参数；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等数字是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；
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，使光固化打印设备的LCD屏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，使光固化打印设备的LCD屏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LCD屏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11为本发明光固化3D打印模型多套切片打印参数设置方法实施例7。如图所示，基于方法3，通过3D切片预处理软件将图7中的人偶模型的颈部位置在Z轴上以X1Y1Z1平面按高度将人偶打印模型划分为H1和H2区域，并在两个区域内各自设定一套模型切片打印参数，并进行切片后得到12层切片；其中，H2区域需要使人偶打印品模型头部能够纹理清晰、表面光滑、尺寸准确，所以切片层厚更薄；H1区域其纹理清晰度稍低、表面光滑度稍差的负面效果却不易看出，所以切片层厚可以更厚；一般在实际打印中，还会在此基础上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；本图中默认以层11、21为底层，所以其对应生成的3s曝光时间参数和15mm/min的成型平台抬起时的运动速度参数可以不同于其他层；
例如，图中最下面阴影部分的层11、21作为底层时，曝光时间定为3秒是因为一般在实际打印中，底层切片在曝光打印时，所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；H1区域内除底层切片以外的每层切片的切片打印层参数都是一致的；H2区域内的每层切片的切片打印层参数也都一致；第31、41层切片为非底层切片，由于其处于H1区域内，所以基于方法3在H1区域内设定模型切片曝光时间为2s，设定成型平台抬起时的运动速度为20mm/min；这里只是为了方便举例，所以仅仅表述了两个参数；模型切片打印参数实际包括了切片打印层参数和层内图像打印页参数这两类参数；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、切片层厚参数等涉及到光固化打印设备的执行和运动机构的运动参数；基于方法3，每层切片内仅包括一套层内图像打印页参数；其中，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、31、a1、b1、c1等数字是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。
图12为本发明光固化3D打印模型多套切片打印参数设置方法实施例8。如图所示，基于方法4，通过3D切片预处理软件将图8中的轮轴模型按不同横截面面积划分不同切片参数设定范围；例如，如果图8中的轮轴模型S1面积为50平方毫米、S2面积为100平方毫米、S3面积为150平方毫米，那么可以设定第1个比较范围为0-60平方毫米、第2个比较范围为60-120平方毫米、第3个比较范围为120-180平方毫米；相对应的范围1内对应设定第1套模型切片打印参数、范围2内对应设定第2套模型切片打印参数、范围3内对应设定第3套模型切片打印参数；在进行切片后得到8层切片；
一般在实际打印中，还会在此基础上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，图中默认指定了最下面阴影部分的两层切片层11、21作为底层切片，而图8中的轮轴模型S2面积刚好又落在范围2，所以此时层11、21切片的打印参数可以是默认底层切片的打印参数，也可以是范围2内对应设定的第2套模型切片打印参数，两种参数可以根据预设默认优先级来进行选择；在本实施例中由于切片层11、21被预设默认指定为底层切片，所以其对应生成3s曝光时间参数和15mm/min的成型平台抬起时的运动速度参数对应的是底层切片参数；而切片层31作为非底层切片，对应的是范围2内对应设定的第2套模型切片打印参数；
第41、51、61层切片为非底层切片，由于其S1面积刚好又落在范围1内，所以基于方法4在范围1内设定模型切片曝光时间为2s，设定成型平台抬起时的运动速度为40mm/min；第71、81层切片为非底层切片，由于其S3面积刚好又落在范围3内，所以基于方法4在范围3内设定模型切片曝光时间为2s，设定成型平台抬起时的运动速度为20mm/min；这里只是为了方便举例，所以仅仅表述了两个参数；模型切片打印参数实际包括了切片打印层参数和层内图像打印页参数这两类参数；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、切片层厚参数等涉及到光固化打印设备的执行和运动机构的运动参数；基于方法4，每层切片内仅包括一套层内图像打印页参数；其中，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、31、41、71、81等数字是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。
通过3D切片预处理软件基于上述4种方法完成模型切片打印参数设定并进行切片后得到每一层切片的切片打印层参数和层内图像打印页参数，光固化打印机再根据具体的切片打印层参数和层内图像打印页参数进行逐层或逐页光固化打印。
