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 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. (15[1])The University of Bath’s Reprap design for this technique is used by (*) Prusa i3. A slicer generates G-codes from a format originally invented for this technique, STL files. One form of this technique focuses UV light into a vat (10[1])of photopolymers. Users of this technique may use Thingiverse to find CAD designs and create them with a Makerbot. (10[1])For 10 points, name this technique that heats and extrudes plastic into layers to construct objects with depth. ■END■
