摘　　要：基于患者颅骨CT数据进行个性化设计、制造的3D打印钛合金个性化颅骨修复体,可完美匹配颅骨个性化缺损,并进行有效修复,但以往相关研究很少关注颅骨修复产品的抗冲击性能。因此,基于电子束熔融技术,该文设计制造了一种新型多孔结构颅骨修复体,并利用落球冲击装置对3D打印钛合金个性化颅骨修复体和数字成型三维塑形钛网进行抗冲击性能试验,对比研究两种产品的抗冲击性能,评价冲击变形对颅内脑组织的影响。实验结果显示,3D打印钛合金个性化颅骨修复体组在冲击过程中平均最大变形为0.7 mm,远小于数字成型三维塑形钛网的平均最大变形5.9 mm。对比研究表明,3D打印钛合金个性化颅骨修复体具有更好的抗冲击性能,还可有效修复颅骨缺损、保护颅内脑组织。Personalized 3D printing titanium alloy cranial prosthesis can be designed and manufactured based on the patient’s CT data to perfectly match and effectively repair the cranial defect.However,previous studies paid little attention to the impact resistance of the cranial prosthesis.In this paper,a novel personalized 3D printing cranial prosthesis is developed based on the electron beam melting technology.The impact resistance of 3D printing titanium alloy personalized cranial prosthesis and digital 3D forming titanium mesh are measured via the falling ball impact device.Results show that the average maximum deformation of 3D printing titanium alloy personalized cranial prosthesis is 0.7 mm,which is much less than the 5.9 mm average maximum deformation of digital forming titanium mesh.In summary,3D printing personalized cranial prosthesis has good impact resistance in repairing the cranial defect and protecting the intracranial brain tissue.
