Build Your Own 3D Printer — Build Day

This hands-on build day guides students through assembling a desktop Fused Deposition Modeling (FDM) 3D printer from a kit, wiring it safely, and performing first power-on checks. By the end, learners leave with a reliable, calibrated machine and the confidence to maintain it at home.

Through interactive lessons and hands-on activities, students will:

​- Follow a safety-first checklist (hotend/bed heat, power supply, pinch points, cable management).

​- Assemble the frame and motion system, route belts, and square/align key components.

​- Wire motors, heaters, and sensors; verify homing and endstops on first power-on.

​- Calibrate bed level and Z-offset to achieve a consistent first layer; validate with a test print.

​- Practice essential care: nozzle swaps, bed cleaning, filament loading/unloading, and troubleshooting.

​- Document their build with a take-home maintenance checklist and “first-print” guide.

Grounded in manufacturer assembly guides and shop safety best practices, this program emphasizes repeatable procedures and responsible tool use.
