Thermosets are irreversibly hardened by curing. Learn about the two distinct ways of curing thermosets, which are used in Additive Manufacturing processes.
Due to the still limited number of available materials for the Selective Laser Sintering process, there is a constant demand for materials with different properties. The addition of any filler to SLS powder typically has an effect on the processing behavior. Today, we investigate the crystallization behavior of PA12 powder filled with copper spheres and flakes.
Thermoplastics and thermosets are important materials in Additive Manufacturing. Learn about the difference between monomers and polymers, their molecular structures and distinct characteristics.
Before we dive into the material science of processing materials with different Additive Manufacturing technologies, we introduce common material groups, distinct molecular structures of material classes as well as discuss other materials used for non-technical applications.
Significant efforts have been made to model and simulate the Selective Laser Sintering process as information about the temperature field in lower layers is difficult to measure. Learn how specific heat capacity can help!
Photopolymers have gained increased importance in many industries. Digital Light Synthesis (DLS), an Additive Manufacturing Technology, is a prime example for the usage of photopolymers. Learn why the NETZSCH Photo-DSC is a proven method to optimize the Additive Manufacturing process.
Today, we answer the question if ABS filament absorbs water from the humidity in the air. Dr. Natalie Ruldolph explains why different plastics react differently to humidity in the environment and gives advice on what home users can do about it.
The plastics used in Selective Laser Sintering (SLS) have a higher thermal expansion when compared with other materials. Therefore, it is important to know how the dimensions of an SLS part change at different temperatures during the build and during use. The higher the thermal expansion coefficient, the more prone are the parts to warpage or curling and the build-up of residual stresses. Learn more!
Additive Manufacturing (AM) encompasses a variety of technologies suitable for producing components from liquid, solid or powder feedstocks. Selective Laser Melting (SLM), a powder-bed fusion process, has become a commonly used AM process for rapid prototyping and component manufacturing using metals, alloys and, to a lesser extent, ceramics. Learn more about SLM, suitable materials and how to optimize input parameters for improved product quality using Thermal Analysis.
While Powder Bed Fusion and Binder Jetting evolved to also using metals, Directed Energy Deposition was specifically developed for this class of materials. We introduce the process principle and variations, benefits and applications of the Additive Manufacturing technology.
