From a single metal powder test, to new alloy development, through to test builds on our in-house AM machine, LPW’s highly experienced AM engineers and technicians are available to add value to your additive manufacturing processes with a full suite of professional services.
Powder Analysis Laboratory
Our specialists offer a comprehensive range of chemical and physical metal powder analysis techniques in both the UK and USA, and are skilled in interpreting just what the data means to your AM process.
All our tests are conducted to ASTM as standard where relevant, with ISO available on request, adding consistency and confidence to your process
Powder AM Laboratory
Using our in-house AM machines to undertake process parameter development, metal powder degradation studies and AM feasibility testing, we also test metal additive manufacturing components in validation studies and undertake root cause analysis of failed builds.
New Material Development
LPW has the metallurgy expertise to offer design and development of new metal alloys, atomised in-house, with test builds on our own AM machines and the testing of built components. We offer individually tailored, complete project delivery with full support and communication.
