3D Printer

A 3D printer is a machine that creates three-dimensional objects by building them layer by layer from a digital model, typically using materials like plastic, resin, or metal.

🛠️ How Does a 3D Printer Work?

1. Design: A 3D model is created using CAD (Computer-Aided Design) software or downloaded online.

2. Slicing: The model is converted into thin horizontal layers using “slicer” software.

3. Printing: The printer builds the object one layer at a time, usually by:

   • FDM (Fused Deposition Modeling): melting plastic filament and laying it down in layers.

   • SLA (Stereolithography): curing liquid resin with a UV laser.

   • SLS (Selective Laser Sintering): fusing powder material with a laser.

📦 Common Uses of 3D Printers

• Prototyping and product design

• Medical models and custom implants

• Architecture and engineering models

• Education and student projects

• Customized tools, parts, or even toys
