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.
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.
Whole layers are generated of cut sheet material layers, which are bonded together before cutting them into the desired shape. We introduce the process principle, benefits and applications of the Additive Manufacturing technology Sheet Lamination.
The Additive Manufacturing technology Binder Jetting is very similar to Powder Bed Fusion. Although there are many similarities of the two processes, the material properties that can be achieved are very different. Learn about the process principle and applications of Binder Jetting!
This week, we move back from thermoplastics to UV-curing resins, which are deposited in a different way. Together with binder jetting, material jetting is the only Additive Manufacturing process that can print in color. We introduce the process principle and look at benefits and applications of Material Jetting.
In a previous article, the process window in the Selective Laser Sintering process with polyamide 12 powder was determined with dynamic measurements. In this article, we explain how isothermal measurements can be used for more advanced studies.
Material Extrusion is the most widespread Additive Manufacturing technology. This week, we look at the process principle, materials used and at benefits and applications of this technology.
Photopolymers used in the Additive Manufacturing technology Digital Light Synthesis (DLS) are challenging materials. Little is known so far about the consequences of increased temperatures, e.g., due to higher room temperatures. A research paper aims to investigate the influence of temperatures on such dual curing resins and finds that the Photo-DSC is most effective in tracking the thermal conversion as well as to identify optimal exposure times.
Powder Bed Fusion (PBF) is one of the oldest Additive Manufacturing technologies invented in the 80s. However, its suitability for end-use parts and its constant innovations are driving this technology further ahead. This week we look at two important variations of Powder Bed Fusion.
Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), the component is built up in layers in a powder bed using a laser beam that passes over the cross-section of the layer to locally melt the powder. In order to characterize a polymer powder for its suitability for SLS and to determine the possible process window, Differential Scanning Calorimetry (DSC) is used. Learn how to set up and interpret the measurements!
