136. ASSESSMENT AND APPLICATION OF 3D PRINTED TURBINE BLADES

Fused deposition modeling (FDM) has primarily been used as a rapid prototyping technology to capture product aesthetics. Parts manufactured using FDM are by nature transversely isotropic. As a result, adapting the design principles successfully applied to advanced composite materials may permit the printing of low-cost and structurally significant components. Materials testing has been conducted to assess the extent of this anisotropy and establish baseline properties for polylactic acid (PLA) parts printed using a low-cost commercially available printer. A modification to the ASTM D638-14 coupon geometry is proposed to improve test reliability. These properties are used to design the blades for a versatile hydrokinetic generator. The capability for onsite manufacturing facilitates both the installation of the device and the subsequent maintenance. The blades would be cheap, easily replaceable in the event of debris strike, and recyclable at the end of their service life.
