LPW Technology introduces world-leading laboratory testing for all your metal powder analysis needs

04 May, 2016

LPW is proud to introduce its world leading laboratory which has the full capability to rapidly and accurately conduct all your metal powder analysis.

A comprehensive range of analysis techniques, for both powder and AM components is available to be carried out by our award winning team.

As Additive Manufacturing starts to be used in production environments, quality becomes ever more critical. The properties of the powder change during use, which can result in failed builds on an AM machine or even component failure in service which can prove catastrophic. At LPW we understand that quality control of the AM process starts with the metal powder.

These tests can either be provided in addition to LPW’s standard certification or on powder supplied to LPW by our customers, perhaps after several uses in an AM machine.

Results can be returned to you in as little as three days. Also, we don’t just do the tests - we understand what the results mean to your AM process. Our Applications Team will help you in the interpretation of the results and support your production requirements.
