Reactive Resin 3D Printing Composites with Z-Direction Reinforcement
Additive manufacturing (AM) has made significant advancements since Charles Hull introduced stereolithography in 1987. Today, it encompasses a wide range of materials, including polymers, ceramics, and metals. However, one persistent challenge has been achieving Z-directional reinforcement in 3D-printed composites. This difficulty arises from issues...

Method for Stiffness Controlled Adhesive Switching and Magnetically Controlled Switchable Adhesive Systems
There is a need for a reversible adhesion system that works without peel or stretch. Recently, it was demonstrated that the force capacity of an adhesive depends on the rigidity of the adhesive material used. Researchers at NDSU have developed a general method to control the stiffness of the material, enabling a switchable adhesive system for low and...

Novel Wire Bending Manufacturing System for Performance Driven 3D Structures
Even with the progress in 3D printing techniques, there are very few alternatives for producing 2D or 3D lattices for use as support structures in objects needing to be lightweight, strong, and flexible. There is currently no manufacturing system that can bend a linear material rapidly, in multiple axes, in multiple and diverse configurations, and with...

Additive Manufacturing Composites with Flow Induced Fiber Alignment
3D printing or additive manufacturing is digital modeling and printing one layer at a time to get a finished product. Stereolithography is a commonly used technique for 3D printing. There are several drawbacks with currently available stereolithography (SLA) resins, prominently with respect to poor mechanical properties. Researchers at NDSU have developed...

Dual Purpose PIG for Cleaning and Internal Integrity Assessment for Pipelines
While cleaning pigs effectively maintain pipeline integrity, most don't conduct condition or integrity assessments. In-line inspection (ILI) pigs, on the other hand, are specifically designed for such tasks, identifying potential risks from in-line defects. However, ILI pigs come with significant drawbacks, including the need for specialized technical...
