Resin vs FDM Printers: Pros, Cons, and Top Picks
If you’re planning to buy a 3D printer in 2025, one of the first questions you’ll encounter is whether to go with a resin (SLA/DLP/LCD) printer or an FDM (Fused Deposition Modelling) printer. These two technologies serve different use cases, offer different advantages, and come with their own learning curves.
In this detailed comparison, we’ll break down the key differences, pros and cons, ideal use cases, and top printers in each category to help you make the best decision for your needs, whether you’re a hobbyist, business owner, or designer.
What is FDM Printing?
FDM (Fused Deposition Modelling) is the most common 3D printing method. It works by extruding melted thermoplastic filament layer by layer to create the final object.
- Materials Used: PLA, ABS, PETG, TPU
- Machine Cost Range: ₹15,000 – ₹60,000+
- Popular Brands: Creality, Anycubic, Prusa, Bambu Lab
Example:
If you’re a mechanical engineer designing parts for robotics or prototyping enclosures, FDM printers like the Creality Ender 3 V3 SE offer durability and scale at a low cost.

What is Resin Printing?
Resin 3D printers (SLA/DLP/LCD) use ultraviolet light to cure photosensitive liquid resin layer by layer for incredibly high detail and smooth surface finishes.
- Materials Used: Standard, tough, castable, or dental resins
- Machine Cost Range: ₹20,000 – ₹80,000+
- Popular Brands: Anycubic, Elegoo, Phrozen, Creality Halot series
Example:
If you’re a dentist printing crowns or a jeweller crafting fine moulds, resin printers like the Anycubic Photon Mono X 6Ks deliver unmatched precision.
Pros and Cons of FDM Printers
Pros
- Lower upfront cost
- Wide range of affordable filaments
- Easier to use and maintain
- Larger build volumes are available
- Good for functional parts and mechanical prototypes
Example:
A startup making custom bike accessories can rapidly prototype durable parts using PETG on an FDM printer.
→ Buy tested & high-quality filaments
Cons
- Lower resolution compared to the resin
- Visible layer lines on the surface
- Difficult to print small or intricate details
- Requires more post-processing for clean aesthetics
Pros and Cons of Resin Printers
Pros
- Extremely high detail and smooth finish
- Ideal for miniatures, dental moulds, jewellery, and product design
- Compact and stylish designs
- Excellent surface quality without sanding
Example:
A design studio prints miniature architectural models with crisp windows and detail using a Phrozen Sonic Mini 8K.
→ Order your first high-precision prototype
Cons
- Resin is expensive and messy
- Requires washing and curing of prints
- Not suitable for large prints
- Fewer material options than FDM
Safety, Smell & Setup
- FDM printers emit some odor with ABS or TPU, but are generally safer to use in open spaces.
- Resin printers need proper ventilation. Uncured resin can irritate skin and eyes and is not ideal for homes with kids or pets.
Setup Tip:
Always use gloves and IPA (isopropyl alcohol) when handling resin. Invest in a UV curing station if you’re going with resin.

Print Speed Comparison
- FDM printing speeds vary depending on settings but typically range from 50–100 mm/s.
- Resin printers can be faster in Z-axis layering but are slower for large-volume models.
Example:
A toy prototype can be printed faster on FDM for testing, but later finalised with resin for better presentation.

Maintenance and Workflow
- FDM printers require nozzle cleaning, bed levelling, and filament swaps.
- Resin printers require resin tank cleaning, filter replacement, and UV curing post-print.
Time Factor:
FDM printers are more forgiving for daily use, while resin printers need a clean environment and more attention.

Final Thoughts
The choice between resin and FDM depends on what you plan to create, how often you’ll use your printer, and how much post-processing you’re comfortable with. Resin printers deliver exceptional detail but demand careful handling and cleanup. FDM printers are more forgiving, cheaper to run, and ideal for everyday functional parts.
For most users starting out in 2025, FDM printers offer the best balance of usability and value. But if your work requires perfection in fine details, go with resin.
