FDM vs Resin 3D Printing: Which Technology Is Right for You?

## How Each Technology Works **FDM (Fused Deposition Modeling)** melts plastic filament and deposits it layer by layer. It's the most common consumer 3D printing method. **Resin (MSLA/SLA)** uses UV light to cure liquid photopolymer resin, producing ultra-fine details impossible with FDM. ## Detail & Resolution Resin printers achieve layer heights of 0.01–0.05 mm (10–50 microns), versus FDM's typical 0.1–0.3 mm. For miniatures, jewelry, and dental models, resin wins decisively. ## Material Strength FDM parts in PETG, ABS, or Nylon outperform resin in impact resistance and long-term durability. Resin parts can be brittle unless using engineering-grade resins. ## Cost | | FDM | Resin | |--|-----|-------| | Entry printer | $169+ | $199+ | | Material cost | ~$15–25/kg | ~$25–40/L | | Post-processing | Minimal | Wash + cure station needed | ## Workspace Considerations Resin emits fumes and requires gloves, ventilation, and UV-safe storage. FDM is far more beginner-friendly indoors. ## Best Use Cases - **FDM**: functional prototypes, large prints, household items, enclosures. - **Resin**: miniatures, jewelry masters, dental models, high-detail art. ## Verdict Start with FDM. Add resin when you need detail that FDM cannot achieve.
