In recent years, 3D printing has shifted from a niche hobby to a mainstream tool for creators, designers, and small businesses. But with so many types of 3D printers available, how do you know which one is the right fit for your needs? Whether you're a first-time buyer or looking to upgrade, one of the most important decisions you'll face is choosing between FDM and resin printing technologies. In this guide, we’ll walk you through everything you need to know—especially if you're considering a resin 3D printer.
What Is a Resin 3D Printer?
A resin 3D printer, also known as an SLA (Stereolithography) or DLP (Digital Light Processing) printer, uses liquid resin cured by UV light to produce models with high detail and smooth finishes. Unlike FDM (Fused Deposition Modeling) printers that extrude melted plastic, resin printers build objects layer by layer through a light-based curing process.
This technology is known for its precision, making it ideal for applications such as jewelry, dental molds, miniatures, and prototypes that require intricate detailing.
Resin vs. FDM: Understanding the Differences
Before diving deeper, it helps to understand the key differences between resin and FDM printers:
FeatureResin 3D PrinterFDM 3D Printer
Print QualityHigh resolution, excellent for fine detailsDecent quality, better for functional parts
MaterialLiquid resin (UV-curable)Thermoplastic filament (PLA, ABS, PETG)
Post-ProcessingRequires cleaning and curingMinimal, usually just support removal
Ease of UseSlightly steeper learning curveMore beginner-friendly
SafetyRequires good ventilation due to resin fumesSafer with fewer fumes
CostTypically higher material costLower material cost
