Here we show you how to use Rhino3d, Grasshopper and AlgoJewels to design a microfluidic chip used in research. --------------------------------------------------------------------- The combination of Rhino3D, Grasshopper, and AlgoJewels creates an exceptional CAD workflow for microfluidic and Lab-on-a-Chip (LoC) devices. It bridges the gap between mathematically precise modeling, algorithmic automation, and micro-scale manufacturing reliability. 1. Grasshopper: Parametric & Algorithmic Fluidic Logic • Dynamic Geometry Adjustments: Microfluidic performance relies on precise channel cross-sections (width, height, aspect ratio), turn radii, and mixing lengths. Grasshopper replaces static 3D models with parametric inputs, allowing you to instantly tweak channel dimensions across an entire chip without redrawing. • Algorithmic Microfluidic Units: Complex fluidic architectures—such as serpentine passive mixers, herringbone channels, flow-focusing droplet generators, and tree-like concentration gradient generators—can be driven mathematically using custom equations and data trees. 2. AlgoJewels: High-Precision Spatial & Curve Transformation Although developed for high-precision jewelry CAD, AlgoJewels provides specialized spatial transformation and topology tools that solve major microfluidic design bottlenecks: • 360-DOF Modular Positioning (Rotate_360_Move_Curve_Global): Provides full 360-Degrees-of-Freedom spatial control to angle, elevate, and tile pre-built fluidic units across 2D chip planes or multi-layer 3D-stacked microfluidic devices. • Seamless Curve Chaining: Joins separate vector segments into continuous, smooth path curves to prevent geometry errors or artificial fluid dead-zones during profile sweeps. • Automated Port Placement: Algorithms track channel start and end points in real time to automatically position inlet/outlet reservoirs, Luer-lock connectors, and PDMS punch locations. 3. Rhino3D: Watertight Solids for Micro-Fabrication • NURBS Precision: Unlike polygon mesh modelers, Rhino’s NURBS engine uses exact mathematical curves, preserving sub-millimeter tolerances essential for micro-scale fluid dynamics. • Watertight Solid Booleans: AlgoJewels components output capped, closed BREP geometry. Swept channel volumes can be cleanly subtracted from substrate bodies via Boolean operations, generating export-ready files for SLA 3D printing, CNC micromilling, or photolithography (SU-8/PDMS) mold masters without mesh slicing failures. ------------------------------------------------------------ For More information Please check out our website http://www.ijewelcad.ca/
