Combat Additive Manufacturing Quality Control Issues with Both Particle Size & Shape Analysis - Asia Timezoned

Additive manufacturing (AM) is cited as one of the twelve most disruptive technologies of 21st centuries. It is currently a major part of Industrial revolution 4.0, as it can be used to produce highly complex parts while reducing waste when compared to traditional subtractive methods.

One of the key parameters required to optimizing the quality objects manufactured this way is to identify the correct raw material and its properties. Properties such as particle size, particle shape, and particle morphology have significant impact on the quality of the final product. Also, the raw material or feedstock can be reused multiple times, however, its reusability is also dependent on above mentioned properties. Lastly, there are international norms and standards methods like ISO and ASTM – 52907 that identifies the method of characterization of these feedstock materials.In this webinar, we will show in detail as to why particle size and shape characterization of the raw materials are critical. For instance, in terms of how these properties affect the packing behaviour and flow characteristics of the powders. Assessment is key as this will affect powder layer formation, ultimately influencing manufacturing efficiency and final part quality.

We will also look at powder recycling in powder bed fusion AM processes. The ability to recycle unused powder offers the potential for great resource efficiency. However, this efficiency depends strongly on the condition of the recycled powder, as any change risks a drop in final part quality. We will also explain how Malvern Panalytical can help you achieve the required ISO norms and adhere to the ASTM standards for feedstock analysis. 

Briefly the techniques of laser diffraction and imaging to highlight the features, benefits, and applications of the instruments based on these techniques i.e Mastersizer 3000, and Morphologi4 respectively. The ease of method development in laser diffraction with the help of dynamic imaging would also be explained. This revolutionary accessory aptly named Hydro Insight adds value in understanding not only the particle size and its distribution buts also the effect of shapes during the same measurements. This would help understand how the Morphologi 4 can be used to classify and compare new and recycled powders based on their particle shape.

This webinar is part of a masterclass series. Our application scientists will give you an overview of different analytical techniques to improve your design and quality control. Our earlier session in May discusses how you can check for microstructural defects in your finished product by way of analysing the powders using X-ray diffraction. More info here


Dr Anand Tadas, Regional Technical Specialist at Malvern Panalytical Dr Tadas has been associated with Malvern Panalytical for more than 10 years. He specializes in the Nanometrics product ranges. Anand received his Ph.D. in Physical Chemistry (colloidal science) from Mumbai India. He is a holder of 3 patents on inert metal processing which are licensed. He has also guided 4 students for their Masters (M.Tech) programs. At present, Dr Tadas is focusing on using the orthogonal characterization of materials particularly in the delivery applications across different sectors.
