3D-printed laboratory devices can enable ambitious research purposes even at a low-budget level. To follow this trend, here we describe the construction, calibration, and usage of the FINDUS (Fully Integrable Noncommercial Dispensing Utility System). We report the successful 3D printing and assembly of a liquid-handling workstation for less than $400. Using this setup, we achieve reliable and flexible liquid-dispensing automation with relative pipetting errors of less than 0.3%. We show our system is well suited for several showcase applications from both the biology and chemistry fields. In support of the open-source spirit, we make all 3D models, assembly instructions, and source code available for free download, rebuild, and modification.

FINDUS：用于生命科学实验室自动化的开源 3D 可打印液体处理工作站。

即使在低预算水平上，3D 打印的实验室设备也可以实现雄心勃勃的研究目的。为了顺应这一趋势，我们在此描述 FINDUS（完全可集成的非商业分配实用程序系统）的构建、校准和使用。我们报告了一个液体处理工作站的成功 3D 打印和组装，价格不到 400 美元。使用此设置，我们实现了可靠且灵活的液体分配自动化，相对移液误差小于 0.3%。我们展示了我们的系统非常适合生物学和化学领域的多种展示应用。为了支持开源精神，我们提供所有 3D 模型、装配说明和源代码，供免费下载、重建和修改。
