Protolabs没怎么具体提他们是怎么干的。
这个视频16～30秒提了一下

这个视频介绍他们的生产流程

更多公开信息基本没了。不过Protolabs的主程序员linkedin倒是提供了一些信息：
Responsible for toolpathing, probing, and CAD application integration of Proto Labs' in-house CNC Mill/Turn CAM package. Created DSLs for type-safe G-Code output, algorithms for 3D collision detection and spatial queries, as well as feature detection for feature-based toolpathing. Help refactor large swaths of the C++ application and libraries in order to unify CNC Mill and CNC Lathe support.
Created prototype ML algorithms for instant evaluation of CAD models for cost estimation / manufacturability metrics. Apart from generic geometric features, used fast machining simulation algorithms to inject CNC machinability constraints into the developed models. A variant of the machining simulation I developed is also used for toolpath verification and optimization in internal applications.
I developed several enhancements to Proto Labs' MIM (metal injection molding) and Thixomolding automatic quoting process - algorithms for estimating the quantity of MIM parts that fit in a sinter tray, and for estimating the maximum material flow length during magnesium casting. Implemented high-performance interactive collision detection used while designing machining fixtures for molded parts.
My first experience in toolpath algorithms was to improve automatic tool selection and to vary tool feed rates based on cut types. Developed interactive visualization for uncut material during automatic and manual tool selection.
另外大概提一下我比较常用的刀路软件HSMWorks，这是autodesk家的产品，对于小用户的三轴2.5D加工是免费的，Fusion 360里集成的版本支持免费3D加工。Autodesk家的好处是各种材料数据库相当完备，而且旗下有instructables提供完善的教程。你们也可以考虑一下联系Autodesk的国内办公室看看有没有办法直接获得一些方案，或者是把下单集成到CAM功能里去，节省加工端的人力，也节省沟通成本。 |
