Ultrafast preparation of nanocrystalline graphene films by quenching method Graphene, a two-dimensional carbon allotrope with extraordinary electrical, thermal, and mechanical properties, has attracted immense interest in various fields including electronics, energy storage, and biomedical applications. The unique properties of graphene can be further enhanced by modifying its structure, such as by creating nanocrystalline graphene films. […]
Gantry systems are an approach to creating a precision motion system for machine tools, such as 3D printers. The terminology is not a precise definition of a structure, as there are various approaches to creating precision motion gantries that diverge in key regards. Gantry systems can also be used for point application print systems such […]
Heat pipes are effective methods to move heat from one location to another within closed-loop systems. They are used as heat recovery systems, thermal control systems for spacecraft, and electronic-device cooling components. A heat pipe is a passive device that transmits heat using capillary action and the laws of thermodynamics. It is made up of […]
In modern manufacturing, the marriage of 3D printing and traditional casting techniques has opened up a world of possibilities. The ability to create custom molds with intricate designs and complex geometries through 3D printing has revolutionized the casting process. By harnessing the power of additive manufacturing, individuals and industries alike can now explore new avenues […]
Glass-Filled Nylon is stiffer than regular nylon-12, because of the glass infill along the entirety of the part. This infill drastically prevents warping and breaking, especially for larger parts. Glass-Filled Nylon parts are highly heat resistant, which allows them to operate under elevated temperatures, making them ideal for uses in the aerospace industry, as well […]
Heat spreaders are objects with a high thermal conductivity that either connect a heat source to another heat exchanger or that release heat to ambient air to prevent the overheating of critical components. These heat-dissipating devices are typically made of copper, aluminum, graphite, or diamond. Different types of heat spreaders, including metallic heat spreaders; phase-change […]
If a part is to be printed in a multi-material, then the part is designed in CAD as an assembly. Each section of the part that is to be printed in a different material is created as its own part file, then integrated into the final assembly to make the multi-material part. Note: mated parts […]
This one has multiple fins which have been cut from a solid block of copper, an excellent heat transfer material. This is an example of a passive heat sink since there is no fan attached to it. How Does a Heat Sink Work? A heat sink makes use of the principles of conductive, convective, and […]
One of the most important metal 3D printer costs is that of the raw materials. Metals for 3D printing are often far more expensive than other forms of the same metal. This is due to special processing and purity requirements. In addition to the raw material itself, some metal 3D printers require inert gas which […]
Metal Binder Jetting (BJ3D) is an additive manufacturing process that builds parts in a composite metal that is 60% stainless steel and 40% bronze. Using a CAD file, a machine will 3D print a part cross-section by cross-section at 0.004” (0.1mm) layers by precisely depositing binder in a stainless steel powder bed. BJ3D uses 316L/Bronze, […]
