As a result, the parts may have to be scrapped and the build has to be repeated with a higher ratio of new material.
At present, PA12 based powdered materials known as PA2200, supplied by EOS GmbH used to create functional plastic prototypes.
One of the conclusions was that after approximately 7-8 builds the properties of the processed material were so badly deteriorated that it was recommended that the remaining material be fully discarded.
