Understanding the difference between FDM and Resin 3D printing is crucial for choosing the right technology for your Melbourne project.

FDM (Fused Deposition Modeling)

FDM is the most common 3D printing technology. It works by melting plastic filament and depositing it layer by layer to build your part.

FDM Advantages

  • Strong, functional parts
  • Cost-effective for larger parts
  • No toxic fumes

Resin (SLA/DLP)

Resin printing uses UV light to cure liquid photopolymer resin layer by layer, producing incredibly detailed parts with smooth surfaces.

Resin Advantages

  • Exceptional detail (25 microns)
  • Smooth surface finish
  • Isotropic strength

Decision Matrix

Choose FDM when you need: Functional mechanical parts, large prints, durability.

Choose Resin when you need: Intricate details, smooth finish, jewelry masters.
