ASTM International’s additive manufacturing technologies committee (F42) is developing a proposed standard that will cover environment, health, and safety principles for the use of polymers with material extrusion (MEX).
In MEX technology, material is extruded through a nozzle to build three-dimensional objects one layer at a time.
“The proposed standard will provide guidelines regarding the safe installation and operation of MEX equipment in an industrial environment,” says ASTM member Francois Richard, manufacturing engineering manager, Pratt & Whitney Canada.
Richard notes that the proposed standard (WK93787) will provide a full overview of requirements for a safe MEX industrial application and will be used to provide uniform and complete information to environment, health, and safety practitioners, including those in charge of conformity and permits.
All interested parties, particularly those with experience in additive manufacturing polymer processes, are encouraged to join in the development of WK93787 and other related proposed standards.
