If you’re new to 3D printing, think of it as digital sculpting with a mechanical hand. Instead of carving away material, 3D printing builds objects layer by layer from the ground up — like stacking ultra-thin pancakes until you get a full stack.

The Basics: Additive Manufacturing Explained

  • Design: You start with a 3D model created in CAD software (like Fusion 360, Blender, or Tinkercad).
  • Slicing: The model is sliced into thin horizontal layers by software such as Cura or PrusaSlicer.
  • Printing: The printer follows these slices, depositing material layer after layer until the object is complete.
Technology Material Type Pros Cons Common Use Cases
Fused Deposition Modeling (FDM) Thermoplastics (PLA, ABS) Affordable, easy to use Lower resolution, visible layers Prototyping, hobbyist parts
Stereolithography (SLA) Photopolymer resin High detail, smooth finish Resin handling, slower Jewelry, dental, miniatures
Selective Laser Sintering (SLS) Nylon powder Strong, functional parts Expensive, powder cleanup Aerospace, automotive parts
Direct Metal Laser Sintering (DMLS) Metal powders (Titanium, Steel) Metal parts with complex geometry Very costly, requires expertise Medical implants, aerospace
