In additive manufacturing porosity can indicate the final mechanical strength and quality of the finished component. Porosity is usually controlled to minimize its affects to material properties, hardness and surface finish. Porosity can actually be a designed parameter for the final product.
For example artificial bone implants need to match the surrounding bone porosities or are specified in the design of the implant to give lighter weight, yet maintain the desired mechanical strength.
Mercury Intrusion is a well proven technique to measure the porosity characteristics of powders and formed product. This technique is based on the intrusion of mercury into a porous structure under stringently
Besides offering speed, accuracy, and a wide measurement range, mercury porosimetry permits you to calculate numerous sample properties such as pore size distributions, total pore volume, total pore surface area, median pore diameter, sample densities
(bulk and skeletal) and percentage porosity.
The AutoPore V Series Mercury Porosimeters from Micromeritics offer a safe and automated route to carrying out high precision intrusion studies on both powdered and solid samples. Resolution in the intrusion profile of 0.1 µL is achievable and the software features comprehensive reporting options.
