Pflugerville, TX 78660 Learn more about Selective Laser Sintering. Using the idea of complex lattice structures as a method of creating repeatable and interconnected porous channels, permeable phantoms with adjustable permeability can be made. This is used in aerospace technology to save on fuel while flying and still maintaining structural integrity and strength of the parts that are optimized. Lattice structure of 3D printing and traditional industry. The action you just performed triggered the security solution. The shape and density of these cells will determine how the part behaves when loads are applied.. While a key advantage of 3D printing is its ability to create freeform and intricate geometries, much of the design freedom offered by 3D printing wouldn't be possible without the use of support structures. Image: A 3D lattice, beam-based, with parabolic beams, which varies in thickness from top to bottom. The resin touched by the laser hardens, then the build platform descends in the resin bath and the process is repeated until the entire part is complete. Fathoms production centers include Stratasys 3D printing and additive manufacturing equipmenthigh-end machines with a wide variety of material options. Simply put, a lattice structure for 3D printing is a repeating or non-repeating 3-dimensional assemblage of connected nodes. by pooya z.
