Accurate and robust method for measuring powder level on a 3D printer

摘要

Powder contamination is one of the biggest challenges on a 3D printer. All the systems in a 3D printer need to be robust enough to be able to work in such aggressive environments. Measuring powder therefore is becoming more difficult, having to avoid using traditional methods like optical sensors. In addition to that, powder is normally not stored flat which makes challenging calculating the powder stored in some systems.
