Additive Manufacturing Metal Powder Analysis - 2

Additive manufacturing (AM) and its continuing evolution offers substantial potential benefits to industry and promises to write the newest chapter in the industrial revolution. AM, sometimes referred to as 3D printing, offers a vast improvement in manufacturing technology with its ability to produce complex designs on demand. These designs include very intricate internal channels and elaborate lattices, providing superior strength to the product and greater single piece functionality, while substantially reducing weight as compared to traditional subtractive manufacturing methods. Although...

Additive Manufacturing Metal Powder Analysis - 3

Particle Size One of the most critical attributes for control, particle size is essential to the AM process. Particle size distribution has a direct influence on powder flowability and the ability to provide a uniform powder bed density. This in turn determines the energy input needed to process the powder grains and also affects the surface finish. Laser diffraction is the most accepted analytical technique utilized for the determination of particle size and particle size distribution. In additive manufacturing porosity will influence the final mechanical strength and quality of the...

Additive Manufacturing Metal Powder Analysis - 4

Surface Area True density is an inherent property of a material, whilst apparent density takes account of occluded voids within a material. Having knowledge of the true and/or apparent density of a material feedstock is important to the powder bed formation and sintering kinetics as well as the porosity, or indeed lack of porosity in the final product. Bulk density is influenced principally by the distribution of particle sizes and shapes. Bulk density is important in establishing material specifications and can give confidence regarding powder flowability and bed formation....
