Course content
Metal and Plastic Powders in the AM process:
- Recycle and quality issues;
- Contamination and Oxidation issues;
- Standards for AM Powders
- Key H&S issues
Basic introduction to handling processes:
- Hoppers for storage and discharge; flow patterns, principles of reliable flow
- Powder flow properties;
- Pneumatic conveying; key components, features and operating issues;
- Fluidisation;
Characterisation and control of powder properties
- Powder flowability/spreadability measurements;
- Environmental effects;
- Density measurements and particle morphology
Basic overview of powder evolution and quality loss
Quality Considerations
- Sampling
- Control of flow properties;
- Segregation in processes
- Particle aggregation;
- Powder electrostatics;
- Particle degradation
Latest Techniques in Spreadability Testing and Layer Quality Control.
- The new technique and instrument developed to quantify the behaviour of a powder when spreading for Additive Manufacturing;
- A new shadowgraphy technique incorporated, used to quantify powder bed surface roughness;
- How the instrument can determine powder bed relative packing fraction, the change in packing fraction, particle size and shape over the build plate, and to evaluate the electrostatic charges over the powder bed.
Format
The first couple of sessions will provide a basic introduction to the subject, leading to in depth studies on quality considerations later in the course. Presentations and demonstrations (where appropriate) will be used to illustrate key points with time for discussion built in.
Why should you attend?
If you work in powder-based AM processing you will find this course to be invaluable as you are guided through the critical aspects of powder handling and management. You do not need any previous formal training to attend, you just need to work in this relatively new field of processing. It will also be extremely useful if you are about to change career direction to AM processing.
Presenters
The course leader is Mike Bradley, Professor of Bulk and Particulate Technologies and Director of The Wolfson Centre. He has worked internationally on design and troubleshooting of bulk solids handling as a commercial consultant and research expert for over twenty years;
Contributions may also be made from the rest of the Team, including
Dr Baldeep Kaur, whose interests lie in characterisation and transportation of bulk materials;
Dr Vivek Garg, whose interests lie in powder flowability;
Dr Atul Sharma, whose interests lie in pneumatic conveying systems.
Dr Hamid Salehi, Chemical Engineer at the University of 杏吧app下载,
Please note: Each of the above companies reserves the right to substitute leaders of equal quality should this be dictated by circumstances beyond their control
