如先前报道的有关3D printed pills和medical devices, product certification and qualification is a challenge to the progress of additive manufacturing in medicine.
In order to ensure new 3D printed hip implants meet stringent standards laid out by the industry, bespoke patient-care provider Baltic Orthoservice (Ortho Baltic) is implementing advanced 3D scanning systems for quality assurance.
严格的扫描系统
Ortho Baltic的产品线包括一系列定制的矫形器,鞋类,3D打印的假体覆盖物和植入物,以改善患者护理。
该公司的髋关节植入物是使用直接金属激光烧结(DMLS)技术定制的。3D打印后,植入物经历了许多后处理步骤,以达到适合在体内使用的标准。这些阶段包括热处理,表面抛光和根据患者受伤的螺钉孔定制磨砂。
这些步骤中的每一个步骤之后,使用尼康计量学的两部分系统对产品进行3D扫描。
70,000 points per second
尼康计量学的Altera cmm能够以每秒70,000点收集对象成像数据来确定植入物的表面。使用增强的传感器性能(ESP),该设备通过捕获反射性和多物质表面来克服3D扫描仪的关键挑战。必威APP精装版
“The CMM with laser scanner is irreplaceable when we need to perform fast checks after each manufacturing and post-processing stage…” – Paulius Lukševičius, Engineer of Mechanics at Ortho Baltic
相比之下,XT H 225 CT是non-destructive testing, and can tell the internal geometry of a part.
“不可替代”激光器
两个系统都用于确保3D打印的植入物匹配由其计算机相等的设计。
Ortho Boltic的力学工程师PauliusLukševičius解释说:“患者特异性植入物是一种定制治疗解决方案,这意味着必须实际上“预先计划”手术,以便将植入物简单地放置在位。”
“The CMM with laser scanner is irreplaceable when we need to perform fast checks after each manufacturing and post-processing stage, especially to check spherical surfaces, bearing surfaces and hole angles.”
3D打印获得识别
Though qualification of new devices in the medical industry is necessarily stringent, new 3D printed implants continue to find a market inacross the globe.
In addition to hip implants,脊柱的支撑性腰笼也是该行业感兴趣的特定领域,定制的设备也可以帮助外科医生进行切口并施加螺丝。
