Additive Manufacturing: Process Options and Controls

Explore various process options in Additive Manufacturing (AM) and the importance of controlling key process variables. Understand the role of ASTM standards, materials, modalities, testing, and the need for process control in AM. Learn about Burloak Technologies' approach in developing AM platforms for commercial space parts.

Presentation Transcript

  1. Additive Manufacturing:Process Options and Controls ASM Chapter Discussion 06 March 2019 Brandon A. Bouwhuis, Ph.D. Aerospace Products Manager | Burloak Technologies

  2. Additive Manufacturing (AM) • Many process options (“modalities”), all of which are sensitive to the Key Process Variables • Feedstock • System/Printer • Consolidated Material Properties

  3. Need for Process Control • ASTM (F42 committee) is developing many standards for AM • Materials (Ti64, AlSi10Mg, Inconel, SS316, …) • Modality (laser/powder, directed energy, …) • Practice (design, critical applications, …) • Testing (powder, parts, …) • AMS is following suit • Feedstock – Process/System – Parts • MMPDS • Working group for “process sensitive materials”

  4. Burloak’s Approach • Two AM platforms qualified to manufacture commercial space parts • Additional AM platforms following specific qualification programs • Process development • Applying aerospace manufacturing requirements and mindset • “If it isn’t documented, it doesn’t exist” • In-house capabilities for support of process development and qual. • Materials testing, heat treating, etc.
