具体地，获取目标打印信息后，可以从目标打印信息中获取目标打印信息中的剥离阈值、最大剥离阈值、剥离时间和剥离增幅，可以将目标打印信息中的剥离阈值、最大剥离阈值、剥离时间和剥离增幅，作为预打印模型的参数值。
例如：当需要对a模型中的第n层进行打印时，若将获取的样本打印信息b作为目标打印信息，可以将样本打印信息b中的剥离阈值、最大剥离阈值、剥离时间和剥离增幅作为预打印模型第n层的预打印模型参数值。
本公开实施例提供3D打印参数值的确定方法，通过获取预打印模型的模型信息，将模型信息与预先设置的模型参数库中的各个样本打印信息进行匹配，得到目标打印信息；根据目标打印信息，确定预打印模型的参数值。当对预打印模型的每一层模型进行打印时，可以将预打印模型的模型信息与模型参数库中的各个样本打印信息进行匹配，根据匹配结果，确定目标打印信息。根据目标打印信息确定预打印模型的参数值，避免了根据经验设定剥离阈值和增幅不适用每一层模型打印后成型模型与料盘的剥离，导致成型模型与料盘的剥离失败，造成模型损坏。提高了打印的效率。
图2为本公开另一实施例提供的3D打印参数值的确定方法的流程示意图；该方法包括：
步骤201、响应于用户触发的打印操作，根据打印操作，获取预打印模型的模型信息。
其中，预打印模型的模型信息可以是预打印模型的模型轮廓、模型面积、层厚、曝光时间、打印光强、打印材料。
具体地，终端可以对用户触发的打印操作进行检测，通过检测用户触发的打印操作，可以根据打印操作，获取预打印模型的模型信息，以便于后续步骤中根据预打印模型的模型信息确定预打印模型的参数值。
步骤202、根据多个历史打印模型对应的模型打印记录，获取多个历史打印模型参数。
其中，历史打印模型参数包括各个历史打印模型中每层模型对应的打印信息，打印信息包括：模型轮廓、模型面积、层厚、曝光时间、打印光强、打印材料、剥离时间、剥离阈值、最大剥离阈值和增幅阈值。剥离时间、剥离阈值、最大剥离阈值和增幅阈值是历史打印模型参数中所包括的。便于后续步骤中根据历史打印模型参数确定预打印模型的参数值。
具体地，终端可以根据多个历史打印模型对应的模型打印记录，从多个历史打印模型对应的模型打印记录中获取多个历史打印模型参数，以便在后续步骤中，终端可以根据多个历史打印模型参数获取预打印模型的参数值。
需要说明的是，历史打印模型参数均可以是将成型模型与料盘剥离时，无任何损坏的模型对应的模型参数。可根据历史打印模型参数确定预打印模型的参数值。
步骤203、根据多个历史打印模型参数中每层模型对应的打印信息，建立模型参数库。
具体地，获取历史打印模型参数中的每层模型对应的打印信息后，建立模型参数库，将历史打印模型参数中的每层模型对应的打印信息存储在模型参数库中。
另外，在对历史模型参数中的每层模型对应的打印信息进行存储时，可以通过将打印信息中的至少一种信息进行分类，分类后进行存储便于查找。
例如：可以将历史模型参数中每层模型的面积进行分类，汇总后可将面积的大小进行排列并存储。还可以根据打印信息中的其他信息进行分类，本公开实施例对此不做限定。
步骤204、确定模型信息与各个样本打印信息的匹配度。
其中，模型信息是预打印模型中模型的每一层对应的模型信息。
具体地，将模型信息与模型参数库中的各个样本打印信息进行匹配， 按照模型信息中的每一种信息可以与模型参数库中的每一种信息对应进行匹配，计算出模型信息与各个样本打印信息的匹配度。
例如：模型信息可以是a模型中的第n层的模型信息，将a模型中的第n层的模型信息与模型参数库中的各个样本打印信息进行匹配，可以将第n层模型的模型信息中的面积信息与各个样本打印信息中的面积信息进行匹配，计算出面积的匹配度，还可以将第n层模型的模型信息中的轮廓信息与各个样本打印信息中的轮廓信息进行匹配，计算出轮廓的匹配度，对模型信息中的每一中信息都和各个样本打印信息中对应的信息进行匹配。其中a和n均为整数。
步骤205、根据每个样本打印信息的匹配度，选取最大匹配度对应的样本打印信息作为目标打印信息。
具体地，得到每个样本打印信息的匹配度后，可以将所有样本打印信息的匹配度从大到小进行排序，可以将最大匹配度对应的样本打印信息作为目标打印信息。
例如：得到每个样本打印信息与a模型中的第n层的模型信息匹配的匹配度后，将所有样本打印信息的匹配度进行排序，获取最大匹配度对应的样本打印信息，将最大匹配度对应的样本打印信息作为目标打印信息。
需要说明的是，预打印模型的每一层模型对应的模型信息都可以在模型参数库中获取到匹配度最大的样本打印信息。若预打印模型分为n层，则n层中每一层都可以获取到最大匹配度对应的样本打印信息，将每一层获取到最大匹配度对应的样本打印信息，作为目标打印信息。
步骤206、根据目标打印信息，确定预打印模型的参数值。
步骤206的过程与步骤103的过程类似，在此不再赘述。
步骤207、根据预先设置的阈值误差范围，计算预打印模型的参数值的误差范围。
由于选取最大匹配度对应的样本打印信息作为目标打印信息时，最大匹配度对应的样本打印信息也和预打印模型的模型信息不完全相同，仍然存在的一定的差异，导致根据目标打印信息确定的预打印模型的参数值也存在一定的误差。
因此，可以根据预先设置的阈值误差范围，计算预打印模型的参数值的误差范围。
具体地，可以根据预先设置的阈值误差范围，计算预打印模型的参数值误差范围，在预打印模型的参数误差范围之内可以对预打印模型的参数值进行适当调整。
例如：若预先设置的阈值误差范围为正负百分之十五，则可以将预打印模型参数值的误差范围设置为正负百分之十五。
步骤208、根据误差范围，确定预打印模型的参数值范围。
具体地，可以根据预先设置的阈值误差范围，确定预打印模型的参数值范围，在确定的预打印模型的参数值范围内对预打印模型参数值进行调整。
例如：若预打印模型的参数值的误差范围是正负百分之十五，则在预打印模型参数值的正负百分之十五的范围内对预打印模型参数值进行调整。若获取的最大剥离阈值可以100N(N是力学单位)，则确定最大剥离阈值的参数值范围可以是85N到115N之间进行调整。
