The same 3D printing technology that aerospace companies use to manufacture jet engine components is now accessible enough for kids to use in their bedrooms. In this episode, Rajiv Patel breaks down FDM 3D printing—what it is, how it works, and why it's become the most practical entry point for young learners exploring additive manufacturing. Whether you're a parent setting up a home STEM lab or an educator looking to introduce real manufacturing workflows, this episode answers the essential question: what do kids actually need to know about FDM technology to build genuine engineering skills?

• FDM (Fused Deposition Modeling) builds objects by extruding melted plastic filament layer by layer, making it fundamentally different from resin or powder-based 3D printing methods that require more complex safety precautions and material handl ...
