3D printers that use powder‐based build materials may be internally exposed to powder dust

contamination. Powder accumulation could eventually lead to electronics malfunction. The printer

should be able to predict electronics failures associated with dust contamination and therefore prevent

unwanted stops that will have a negative impact on productivity. Experience has shown that it is difficult

to prevent powder dust from reaching certain areas of such a 3D printer. Some types of powder are

slightly conductive. Metallic dust aggravates the issue. How could we monitor powder contamination on

our electronics in an affordable way?
