The technology under Pernett's brand.

9 Participants

在国内教学教具市场,普奈特之所以能够保持竞争优势,核心并非单纯的品牌营销,而是深耕技术的持续叠加。自 2010 年成立技术研发中心以来,团队每年投入约 1.2 亿元用于材料研发、数字化建模与工艺优化,累计获批发明专利 45 项,实用新型专利 28 项,形成了从概念到成品的闭环技术链。

The technology under Pernett's brand.

Technology R & D system

研发团队采用“双轨并行”模式:一条轨道专注于生理解剖学模型的几何精准度,另一条轨道聚焦功能性材料的仿真性能。2021 年引入的多体动力学仿真平台,使得骨骼关节模型在受力测试中误差率下降至 0.3%,远低于行业平均的 1.2%。该平台的核心算法基于美国 MIT 的有限元分析框架,经过本土化改进后实现了实时渲染。

Material and process innovation

在材料选择上,普奈特坚持使用医用级聚氨酯与生物相容性树脂的复合配方。2022 年完成的“低温交联工艺”能够在‑20℃环境下完成固化,既保证了模型细节的完整保存,又将硬度波动控制在±5%。同年,配合德国 Ultimaker S5 Pro 的高精度 FDM 打印机,层厚实现 0.05 mm 的微米级分辨率,单件心脏模型的血管分支细节从原来的 5 mm 粗线提升至 0.8 mm 的细丝。

Interdisciplinary modelling platform

为了满足医护、生命科学与工程教育的交叉需求,普奈特搭建了“模块化拼装平台”。例如,2023 年与上海某高校合作开发的“呼吸系统实验套件”,将肺部弹性材料与可视化气流传感器融合,学生在模拟呼吸循环中可以实时读取阻力曲线。实验数据显示,使用该套件的学生在呼吸生理概念掌握测验中平均得分提升了 18 分。

Quality control and data driver

质量管理不再停留在抽样检验,而是全流程数据追踪。每件出厂产品都配备二维码,扫码即显示生产批次、材料配比、3D 打印参数以及三维坐标偏差报告。2024 年第一季度的内部审计显示,基于大数据预警的返修率从上一年度的 2.4%降至 0.9%。这种透明化的质量闭环在国内教学教具领域仍属罕见。

The fall of technology has made every one of Punett's trajectories look like a precise conversation about the teaching landscape. Standing in front of the lab's workstation, seeing a hand holding a just printed neurological model, and feeling the dark lights behind dozens of engineers?

  • I can't read back.

    That's a good number. Forty-five invention patents.

  • Dragon spirit.

    It's kind of cold in here, and I can't believe that companies are willing to spend so much on research and development.

  • The tiles.

    120 million years... how do you figure out the size of this input?

  • Flaming heart.

    The anatomy model of their home, which was previously represented, was indeed one step higher than that of their peers.

  • A traveler.

    The 0.9 per cent return rate is a bit false, too much.

  • Fogsy.

    Can anyone read this technical article?

  • Maplewood night.

    Half a day, I remember that 0.05 mm thick, and the rest is digital.

  • Painted Sky

    Do you know which hospital they work with?

  • ButtercupBliss

    That's good.
