3D Printing Basics
3D printing builds objects layer by layer from a digital file. It’s used for prototypes, custom parts, and one-off items. Below are the main technologies explained simply.
What is Prototyping?
FDM (Fused Deposition Modeling)
Affordable and strong — best for functional parts and fast prototypes
FDM printers melt plastic filament and build parts layer by layer. It's the most common and cost-effective 3D printing method.
Best for:
- Functional prototypes that need to be strong
- Large parts and assemblies
- Parts that will be handled or tested
- Cost-effective production
SLA (Stereolithography)
Very detailed and smooth — best for visual models and high-fidelity prototypes
SLA printers use light to cure liquid resin into solid plastic. This creates very smooth, detailed parts with fine features.
Best for:
- High-detail visual models
- Small parts with fine features
- Smooth surface finish requirements
- Jewelry, miniatures, and precision parts
Beyond 3D Printing
Reverse engineering turns a physical part into a CAD model; prototyping helps you test ideas before full production.
