... directly using various powders, including polymers and fillers. In addition, the influence of extrusion on the orientation of thermal conductive filler is also investigated. Design/methodology/approach To ensure the plasticizing effect and the mixing ability, the printing head is a conical twin-screw...

...Arad Azizi; Fatemeh Hejripour; Jacob A. Goodman; Piyush A. Kulkarni; Xiaobo Chen; Guangwen Zhou; Scott N. Schiffres Purpose AlSi10Mg alloy is commonly used in laser powder bed fusion due to its printability, relatively high thermal conductivity, low density and good mechanical properties. However...

... Scanning path Thermal modeling Kinematical behavior Thermal conductivity Laser Power Bed Fusion (LPBF) allows producing three-dimensional (3D) parts layer by layer from 3D model data. This technology involves locally melting a layer of powder (between 20 and 100 μm) using a laser beam. LPBF has...

.../approach In this paper, micron diamond particles were embedded in 3D printed geopolymers as a potential thermal sensor material to detect the inner heat change. The authors use synthetic micron diamond powder to reinforced the anti-corrosion properties and thermal conductivity of geopolymer and apply...

...Mengqi Yuan; Timothy T Diller; David Bourell; Joseph Beaman Purpose – The purpose of this paper is to acquire thermal conductivities of both fresh and preheated polyamide 12 powder under various conditions to provide a basis for effective and accurate control during the laser sintering (LS...

... for the layer‐by‐layer fabrication. The model encompasses the effects of the temperature‐ and porosity‐dependent thermal conduction and radiation as well as the temperature‐dependent natural convection. Substrate preheating is found to be important in preventing the formation of cracks in the dental porcelain...
