Custom 3d Printing Nozzles for Geometric Customization of Materials Deposition
THE CHALLENGE
Problem with current extrusion-based additive manufacturing lies in its heavy dependence on standard round nozzles, which limit the ability to control the shape of material strands as they are deposited. This restriction forces companies to rely on workarounds such as complex software strategies, fine-tuned printing parameters, or costly...

Multi-Axis Continuous Fiber Extrusion Tool
THE CHALLENGE
Traditional composite processing methods such as wet layup and pultrusion struggle to create small, detailed shapes with properly aligned carbon fibers. While 3D printing with short carbon fibers improves strength slightly, the chopped fibers limit their full potential. Continuous carbon fiber 3D printing works well for simple, flat printing...
