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

Two Different Worlds

FDM (filament) and resin (SLA/MSLA) printing produce very different results. Neither is "better" — they serve different purposes.

Resin wins by a mile. Layer heights of 0.025-0.05mm produce nearly invisible layers. FDM at 0.12mm still shows visible layer lines.

For miniatures, jewelry, and dental models, resin is the clear choice.

FDM wins here. PLA and PETG parts are stronger and more durable than most hobby resins. Standard resin is brittle and cracks under impact.

Engineering resins (tough, flexible) close the gap but cost 2-3x more.

FDM printers typically have larger build volumes. A €200 FDM printer can print 220×220×250mm. A €200 resin printer is limited to ~130×80×160mm.

Resin requires washing in IPA/water and UV curing. It's messy, smelly, and the uncured resin is toxic. FDM parts just pop off the bed.

FDM filament: €15-30/kg. Resin: €25-50/L. But resin prints are typically smaller, so the cost per part can be comparable.

Resin fumes are harmful. Always use gloves, a respirator, and good ventilation. FDM printing (with PLA) is safe in a normal room.

Start with FDM for versatility and ease of use. Add resin later if you need ultra-fine detail. Many sellers run both technologies.
