Abstract Scope |
Ti-5553 is an important alloy for complex LPBF geometries, due to its beta phase stabilization resulting in lower residual stresses. Aerospace parts are being light-weighted, by replacing bulk parts with lattice using topology optimization approaches. These parts consist of bulk regions, skin regions and strut regions, all of which require different printing parameters to generate the correct qualities. In this presentation, I will show iterative DOE's (Design Of Experiments), for 1 cm^3 cubes, 0.2x1 cm thin walls, and 1x1x0.5 cm 10% dense octet truss unit cell lattices. Measurements of dimensionality, porosity and surface roughness are used to build a response surface against power, speed, spot size and hatch spacing, along with scan path type allowing the ability to narrow in on a set of printing parameters for a required application. A comparison of traditional DOE approaches versus commercially available DOE tools, Senvol and Intelligens.ai will be evaluated. |
