Laser Scanning of organic spruce-root based geometry to create a manifold mesh for Powder Bed Fusion Additive Manufacturing Process
(University of Oregon, 2022-06) Rafizullah, Kazi
This paper highlights the equipment, software, parameters, and workflow required to 3D-Laser scan a complex organic-shaped art piece and physically reproduce it using Powder Bed Fusion (Selective Laser Sintering) technology. The model used for this experimentation was a Coos Clam Basket, which is a museum art piece woven by artist Sara Siestreem (Hanis Coos). This paper is heavily weighted on the methodology section, as the purpose of this paper is to allow for the re-creation of similar work. The 3D-Laser Scanner used for this project was the Creaform HandyScan Black Elite series, which uses a blue laser to detect and capture surfaces. The majority of the post-processing using raw scanned files was performed using 3D-Systems GeoMagic Wrap software. 3D-Printing risk failure analysis and digital sectioning were performed using Materialise Magics V25. The technology used to recreate the physical model was Powder Bed Fusion (or Selective Laser Sintering) method using Formlabs Fuse-1 printer. The 3D-Printed piece was printed and at the time of this writing is on scheduled exhibitions at museums and galleries across the Pacific Northwest.
