If you’ve spent any time tinkering with FDM 3D printers, you already know the thrill of watching an object materialize layer by layer. For years, I thought my trusty filament printer was all I needed—until I decided to try out a 3D resin printer.
I didn't expect it to change how I approach printing altogether.
Whether you’re a hobbyist, a miniature painter, a designer, or someone looking to prototype with precision, a resin printer might just be what your toolkit is missing. In this post, I’ll walk you through my experience, the differences I noticed, the pros and cons, and whether making the switch is worth it for you.
A 3D resin printer uses liquid photopolymer resin and UV light to build models layer by layer, unlike FDM printers which melt plastic filament. This process is called stereolithography (SLA) or masked stereolithography (MSLA), depending on the specific technology used.
Because it cures resin with light instead of extruding melted plastic, a resin printer can capture far finer details and achieve much smoother surfaces. This precision is a game-changer if you work on small-scale models or need professional-level detail.
For me, it started with frustration.
I was printing miniatures for tabletop games, and while my FDM printer could churn them out fast, the print lines and details were lacking. I kept sanding, priming, and reworking parts just to get them looking decent.
After seeing some jaw-dropping prints from resin machines online, I decided to give one a shot. I picked up a mid-tier 3D resin printer and printed the same model I'd been struggling with.
The result? Sharper lines, no visible layers, and a surface so smooth it didn’t need post-processing. I was floored.
Let’s break it down a bit further:
The first thing that hit me? The smell.
Resin printing isn’t exactly a plug-and-play experience. You need gloves, isopropyl alcohol, and a well-ventilated space. After each print, there’s a cleaning and curing process—not something I was used to with my FDM setup.
But once I got into a routine, it became manageable. What surprised me even more was how reliable the printer was. I experienced fewer failed prints, especially for small, intricate models. No more spaghetti-like stringing or layer shifts.
Another bonus: the learning curve was shorter than I expected. Slicing software like Lychee and Chitubox make it intuitive to hollow models, add supports, and optimize print settings.
Here’s who I think benefits most from using a resin printer:
That said, if you mainly print large structural objects, mechanical parts, or low-detail prototypes, an FDM printer may still be your best friend.
But if you care about surface finish and fine detail, a 3D resin printer makes a noticeable difference.
If you’re thinking about diving in, here’s some advice from someone who just went through it:
Absolutely.
For me, using a 3D resin printer has unlocked a new level of creativity and quality in my prints. It’s not the right tool for everything, but for the things it excels at—miniatures, intricate pieces, beautiful prototypes—there’s really no contest.
If you’ve been thinking about making the jump, I say go for it. Just go in prepared, and you'll find it a rewarding addition to your maker setup.
Whether you're looking to print high-detail miniatures or produce polished prototypes, a 3D resin printer opens up new possibilities that filament printing just can't match.

Comparing Resin vs. FDM Printing
Let’s break it down a bit further:
| Feature | FDM Printer | 3D Resin Printer |
|---|---|---|
| Print Detail | Moderate to good | Exceptional (especially on small items) |
| Surface Finish | Requires post-processing | Smooth right off the plate |
| Material Handling | Easy (solid filament spools) | Messy (liquid resin, gloves required) |
| Odor & Ventilation | Mild (some smell from filament) | Strong (resin fumes, ventilation needed) |
| Speed | Faster for larger prints | Slower but consistent quality |
| Cost Per Print | Lower | Slightly higher due to resin use |
| Cleanup & Maintenance | Easier | More complex |

Is a 3D Resin Printer Right for You?
Here’s who I think benefits most from using a resin printer:
- Miniature painters and modelers: You’ll love the sharp detail and how little prep work is needed before painting.
- Jewelry designers or small part prototypers: Precision is unmatched.
- Cosplayers needing detailed accessories: A resin printer handles intricate parts beautifully.
- Makers focused on aesthetics over function: Resin prints win on looks.
That said, if you mainly print large structural objects, mechanical parts, or low-detail prototypes, an FDM printer may still be your best friend.

Tips for Getting Started with Resin Printing
If you’re thinking about diving in, here’s some advice from someone who just went through it:
- Pick the right printer: Brands like Anycubic, Elegoo, and HeyGears offer quality machines for beginners and pros alike.
- Set up a proper space: You’ll need good airflow, a UV curing station, and a cleanup area.
- Always wear gloves: Resin isn’t skin-friendly. Handle with care.
- Use high-quality resin: It affects both your results and the safety of your workspace.
- Start with small prints: Don’t go big right away. Focus on mastering the basics first.
Final Thoughts: Was It Worth the Switch?
Absolutely.
