ExOne licenses ORNL method to 3D print components for
Jun 22, 2020· Instead of tungsten and copper, ORNL’s method comprises a unique way of binder-jet printing a lightweight ceramic called boron carbide, or B 4 C, that is then infused with aluminum. The resulting material is called a B 4 C – Al metal matrix composite. The prototype collimators were formed using an ExOne binder jet machine at DOE’s Manufacturing Demonstration Facility at ORNL.
NylonX is an amazing, reinforced nylon filament. By adding micro-carbon fibers to nylon, you get a tough filament capable of printing parts with stiffness, impact resistance, and high tensile strength. NylonX is an engineering grade filament, ready for hobbyists and advanced users alike, which gives you the durability of nylon coined with the stiffness of carbon fiber.
The Essentials for Applying Sizing to Carbon Fibers
Protective qualities of sizing can be measured using a broken filament counter. Friction coefficient measurements can be taken to compare between sizing materials. Sizing material can have a large impact on the spreadability of a fiber, and providing a spreading station with width monitoring system can give instant feedback for this characteristic.
