An ultra‑clear, high‑resolution photopolymer resin engineered for 3D printing transparent monolithic microfluidic devices with enclosed channels and excellent optical clarity. This resin allows precise features down to ~80 µm with smooth surfaces and no need for sanding or coatings. Ideal for direct‑use microfluidics, imaging, and prototyping workflows.
This resin is exclusively available to owners or operators of CADworks3D systems.
General
High‑clarity resin for transparent microfluidic devices
The Clear Microfluidic Resin is formulated for producing monolithic microfluidic devices with enclosed channels, outstanding transparency, and minimal surface roughness. Its low viscosity enables embedded channels to drain cleanly during printing and cleaning, and it remains inert under fluorescent imaging. Perfect for rapid prototyping of functional, observable devices.
Cross Junction
XY: 80 μm | Z: 250 μm
Serpentine
XY: 200 μm | Z: 350 μm
Designed for transparent microfluidics
- Excellent optical clarity for in‑device observation and microscopy
- Low viscosity enables clean embedded channel printing and drainage
- Fast workflow: 1 day fabrication from CAD to device
- Inert under fluorescent light for imaging and analysis workflows
