Key Takeaway: 3D printing can produce fast, strong, reliable FRC parts with the right materials and design.

This 45-minute session helps FRC mentors launch or scale 3D printing. Geared to beginner–intermediate teams, it covers printers (Bambu Mini, X1C/H, Markforged), materials (PLA, PA6/PA12, PC, TPU), and when to use each. Learn print tuning (nozzles, XY holes, supports), strength-driven design (orientation, walls vs infill, inserts), and shop habits. See how dry filament and smart workflows yield accurate, durable, competition-ready parts fast.
