The first of a series of informative laboratory services datasheets has been released by LPW Technology Ltd, Runcorn, UK. Designed to describe the processes and benefits of each of the chemical and physical analysis techniques LPW offers for Additive Manufacturing, the series debuts with Karl Fischer Titration testing.
Karl Fischer Titration is a fast, precise moisture content test suitable for all metal powders and alloys, LPW reports. It can determine 0.001 to 100% moisture content in metal powders and is accurate to within 1% of the moisture detected in the sample.
“We’ll take an in-depth look at how each test works, the results it yields, and the advantages it may have to offer – if any – compared to other methods,” stated Lisa Holman, LPW’s Quality Engineer.
“We’ve chosen to start the series with a test that has the potential to identify whether an AM build problem is associated with reduced powder flow due to moisture content,” added Holman. “Understanding the condition of the powder through repeated builds adds confidence to the integrity of the components and can reduce overall down time.”
A new laboratory service datasheet will be released each month, the company states. The latest datasheet can be viewed through LPW’s website.
