Additive Manufacturing / 3D Printing Materials Additive   manufacturing,   also   known   as   3D   printing,   is   growing   at   an   amazingly   fast   rate   and   presents   exciting   new   opportunities   in   an   incredibly diverse range of applications and industries. The   porosity   of   raw   materials   significantly   influences   manufacturing   parameters:   the   size   and   volume   of   inter-particle   void   spaces,   related   to particle   size   and   shape,   determine   the   physical   packing      of   a   powder   bed   and   In   turn,   this   will   determine   manufacturing   conditions   and   effect the physical properties and appearance of finished articles.

Additive Manufacturing / 3D Printing Materials Additive manufacturing, also known as 3D printing, is growing at an amazingly fast rate and presents exciting new opportunities in an incredibly diverse range of applications and industries. The porosity of raw materials significantly influences manufacturing parameters: the size and volume of inter-particle void spaces, related to particle size and shape, determine the physical packing  of a powder bed and In turn, this will determine manufacturing conditions and effect the physical properties and appearance of finished articles. Key Points: Characterisation    of    raw    materials    to    determine    manufacturing conditions BET Surface Area is critical to raw material specifications BET Surface Area influences the sintering process Determination of particulate void space and particle packing Characterisation of finished pieces for porosity Porosity effects mechanical strength, hardness and finish quality Introducing porosity is necessary for reducing weight Pore    size    and    volume    is    critical    to    matching    architectures    & scaffolds Porosity is also critical to the  weight / strength balance Assistance with data interpretation Expansiv e data presentation and comparative overlay options       A range of techniques are available for the characterisation of both raw materials and finished articles and these can be applied to a very wide range of materials: including thermo-plastics, metals, alloys, glass and biomedical materials. BET Surface Area can be applied to the determination of printing conditions as it influences particle sintering. Many materials used in additive manufacturing are of low surface area, such as thermoplastics and metal powders, and at MCA Services we offer BET Surface area determination by krypton adsorption which is particularly suited to these materials.       Mercury porosimetry is used for the determination of pore volume, pore size distribution and volume porosity over a wide range of pore sizes. For raw materials this can be applied to the characterisation of inter-particle void spaces, related to particle packing, and provides complimentary information to particle size and shape analysis. Mercury porosimetry can also be applied to finished articles and becomes important since porosity effects physical properties: such as mechanical strength, hardness and the anesthetic quality of the surface finish. In some applications, for example bio-medical, it is critical to match the porous nature of  the manufactured article with the existing support material. Mercury porosimetry is particularly useful as it provides a full characterisation of pore volume and pore size distribution as well as the measurement of volume porosity.        MCA Services also offers the measurement of bulk density, absolute density and skeletal density via our mercury pycnometry and helium pycnometry options. The density of both raw materials and finished articles is often part of the specification parameters and combination of bulk and skeletal densities can be applied to the determination of Total Pore Volume. Deviation from theoretical density can be applied to the determination of blind pore  Key Techniques Analysis of powders, granules and finished pieces BET Surface Area - including krypton adsorption for low area materials Mercury Porosimetry - pore size, pore volume & pore area distribution Mercury Porosimetry - characterisation of particle packing / void space Permeability and Tortuosity measurement via Mercury Porosimetry Gas Adsorption - pore size, area  & volume distribution of mesopores Density measurement - absolute density, bulk density & skeletal density Measurement of Total Pore Volume
