Wave Weaver
Abstract — Selective Laser Sintering (SLS) is a 3D printing technology that does not require support structures and does not sacrifice component strength. However, it is more wasteful than other additive manufacturing methods. The goal of Wave Weaver is to reduce this waste as well as lower the cost of the technology. Traditional SLS printing works by packing a bed with powdered material and using a laser to selectively sinter the powder together into the part. The waste is introduced when the powder in the bed not used for the part is heated due to heat dispersion from the powder that is sintered. The powder can only be heated a finite amount of times before it is no longer usable. To address this problem, Wave Weaver seeks to remove the need to pack the bed by directing only the powder needed for the part itself into the proper shape with a Chladni plate where it could be sintered all at once. This also has the potential to remove the need for the expensive laser further lowering the cost.
