This sub-group for Near Net Shape (NNS) manufacturing has been set up to facilitate active discussion and transfer of up-to-date information around the manufacturing processes, research activities and networking opportunities that constitute this innovative field.

Near Net Shape (NNS) manufacturing encompasses a wide range of innovative techniques for the accelerated and sustainable production of parts.  The benefits of NNS are widely recognised and particularly advantageous for production of complex geometries which cannot be formed by other techniques, for customised production or small batch sizes and for sustainable manufacturing.  Advantages include the following:

  • the ability to produce parts which are much closer to the finished size, shape and tolerance
  • the ability to produce highly customisable or complex shapes
  • maximisation of utilised material in the finished part versus wastage in comparison to machining processes
  • reduction of the total number of manufacturing stages
  • reduction of cost of manufacturing, resulting from a combination of the above factors
  • reduction of time for manufacturing, with manufacturing times often being more than halved
  • an overall energy saving possible throughout the entire manufacturing process
  • a greater uniformity from part to part and an overall improvement in quality

The capabilities, benefits and challenges across the full landscape of NNS processes is evaluated in detail in a recent review of NNS written by Matthew Sier on behalf of the Materials Community, which can be found at the following:
