Temperature distribution in powder beds during 3D printing

Rapid Prototyping Journal, 2010
PurposeThis purpose of this paper is to report about the temperature distribution in metal and ceramic powder beds during 3D printing. The differing powders are thoroughly characterized in terms of thermal conductivity, thermal diffusivity, emissivity spectra and density.Design/methodology/approachThe temperature distribution was measured in a 3D ...

Penetration Study of Liquid in Powder Bed for 3D Powder-Bed Printing

2020
Powder-bed 3D printing technology is attractive as it allows to build complex structures and optimize cost and time. The liquid is sprayed to bond the powder bed at pre-determined positions layer by layer. After print, the non-bonded particles are removed during post-processing.

Powder Bed Fusion Techniques in Metal 3D Printing: A Review

Applied Mechanics and Materials
The use of 3D printing (additive manufacturing) with metal has grown significantly in demand recently, greatly reducing the time and expense required to produce complex interconnected metal components. This method minimizes material wastage, facilitates material recycling, and eliminates the need for support materials.

3D printing of titanium parts from titanium hydride powder by solvent jetting on granule beds

International Journal of Refractory Metals and Hard Materials, 2020
Abstract Titanium parts are produced by the “Solvent on granules 3D-Printing” technique (SG-3DP). Angular Titanium Hydride powders are used. A special purpose table-top machine, designed and built in a previous development, is used to print green parts, which are subsequently debinded, dehydrided and sintered in a muffle furnace.
