Which Is Right for Your Project?

When choosing a 3D printing method for your next project, the two most common technologies you’ll encounter are FDM (Fused Deposition Modeling) and Resin Printing. Both offer unique advantages, and selecting the right one can make all the difference in quality, cost, and turnaround time.

What Is FDM 3D Printing?

FDM printing uses melted thermoplastic filament (like PLA, PETG, or ABS), which is layered onto a build plate to form your object. It’s widely used due to its affordability and ability to create strong, functional parts.

• Best for: Prototypes, mechanical parts, enclosures
• Material choices: PLA, PETG, ABS, TPU
• Pros: Cost-effective, durable, large part sizes
• Cons: Less detailed finish, visible layer lines

What Is Resin 3D Printing?

Resin printing (SLA or MSLA) cures liquid resin with UV light to create highly detailed prints. It’s ideal for small, intricate models like miniatures or dental molds.

• Best for: Miniatures, models, dental parts, jewellery
• Material choices: Standard resin, flexible resin, high-temp resin
• Pros: High detail, smooth surfaces, precision
• Cons: Brittle, messy post-processing, more expensive

FDM vs Resin: A Side-by-Side Comparison

Feature	FDM	Resin
Detail Level	Moderate	High
Durability	Strong	Brittle
Cost	Lower	Higher
Post-Processing	Simple	Messy / Needs curing
Size Limits	Large builds	Small precision

Which One Should You Choose?

If you need a durable prototype or mechanical part, FDM is likely your best bet. But if your design demands intricate detail or surface smoothness, resin printing is the way to go.
