Wolfson Centre

Powder Handling and Flow for Additive Manufacturing

Course dates

This course will be held again in 2023.

The course will run on line over 5 sessions;  each session will start at 13:00 hrs UK time; all sessions need to be attended to complete the course.

Day 1: General introduction from presenters (30 mins) / Introduction to Powder Behaviour (30 mins) / Quality issues /Current approaches to measuring powder particle characteristics (90 mins)

Day 2: PSD / recycling issues / powder moisture (120 mins)

Day 3: Latest Techniques in Spreadability and Layer Quality (60 mins) / Powder management and maintenance of quality / powder evolution (120 mins) /

Day 4: Characterisation of powders (60 mins) / Review of standards (75 mins)

Day 5: Tumbling test and quality considerations (60 mins) / Control of flow properties (90 mins) / review and course closure

Each day provides the opportunity to discuss operational issues with the presenters and other delegates.

Course Fee

£775 per delegate. Discounts are available for group bookings and returning delegates.

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

** New Section** 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.


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.


Experts from the Wolfson Centre for Bulk Solids Handling Technology, Carpenter Additive and Fraunhofer IFAM Institute, Bremen have come together to pool their knowledge to provide a varied programme of presentations and discussions.

Prof Mike Bradley and Richard Farnish, Director and Technical Director of the Wolfson Centre respectively, have worked internationally on design and troubleshooting of bulk solids handling as a commercial consultants and research experts for over twenty years.

Dr Joseph Oluleke, Specialist, Materials Manager at Carpenter Additive, has over 5 years of academic and industrial experience in metal powder AM, including AM powder production through atomisation and spheroidisation, AM powder post processing, powder behaviour and powder evolution.

Dipl-Ing. Claus Aumund-Kopp, Group Leader for AM at the Fraunhofer IFAM Institute in Bremen, has worked with metal powders for AM powder bed fusion and AM binder jetting approaches for over fifteen years.

Dr Hamid Salehi, Chemical Engineer at the University of Greenwich, joined the University 3 years ago as a Researcher studying  powder handling projects in the Wolfson Centre under the guidance of Prof Bradley before moving to his current post whilst maintaining contact with the Centre. He will be reporting on his latest findings.
