Dawn White used a sonotrode to invent one type of this process called ultrasonic consolidation. Continuous direct light processing is a high-speed version of this technique. Skirts, brims, and rafts are added (15[1])in this technique to mitigate rugosity. The benchy boat is used to benchmark this technique. Fewer topology-optimized parts are generated by the AMF format that encodes the inputs of this technique compared to an older format. The University of Bath’s Reprap design for this technique is used by (15[1])(*) Prusa i3. A slicer generates G-codes from a format (-5[1])originally invented (10[1])for this technique, STL files. One form of this technique (10[1])focuses UV light into a vat of photopolymers. (10[2])Users of this technique may use Thingiverse to find CAD designs and create them with a Makerbot. For 10 points, name this technique that heats and extrudes plastic into layers to construct objects with depth. ■END■
