Interstitial Control during Additive Manufacturing

Summary:

ISURF #4767 is a method to accurately predict, and thus control, the final composition of additively manufactured metal parts.

 

Description:

Metal-based additive manufacturing (AM) is a rapidly growing method in the production of intricate or complex parts. Currently, there is no standard method to predict the composition of the as-deposited materials. Complicating the ability to do so is the fact that AM systems range in operating conditions such as vacuum or positive pressure and the purity of gases used in positive pressure cases. ISURF #4767 is a method applying the Langmuir Model to predict the final composition of AM produced parts based on the loss of volatile products or capture of gaseous species. The ability to predict as-deposited composition can allow control via sacrificial solutes. This ability of control can improve final part properties and give higher degree of quality control over parts produced via AM.

 

Advantage:

• Improved part performance from higher control of part composition

• Higher quality control, parts produced will be more similar part to part

• Composition predication allows changing of process conditions during manufacturing to keep parts within specifications
