Introduction to 3D Printing: How It Works

3D printing, also known as additive manufacturing, builds parts layer by layer from a digital model.

Start with a watertight CAD file, export to .STL or .3MF, then slice to generate G‑code.

Why it matters

• Rapid prototyping accelerates iteration cycles.
• Customization without expensive tooling.
• Less waste vs. subtractive methods.

Tip: Nail the first layer—clean bed, proper Z offset, and slow speed.

After printing, remove supports and consider light wet sanding for a smoother finish.
