If you’ve been shopping for a 3D printer — or wondering whether you picked the right one — you’ve probably come across the big debate: resin vs. FDM.

Both technologies are more accessible than ever. Entry-level FDM printers now start under $300, and resin printers capable of stunning detail aren’t far off in price. But they’re not interchangeable — and choosing the wrong one for your project, space, or skill level can lead to frustration, mess, and wasted money.

So which one should you choose?

In this guide, we’ll walk through the differences between FDM and resin printing, the pros and cons of each, what kinds of projects they’re best for, and what you should expect when it comes to cost, safety, and maintenance. Whether you're a hobbyist, a teacher, or an artist printing for exhibitions, this article will help you make a confident, informed choice.

A quick note before we begin:
At 3D Printing by Bokey, we focus exclusively on FDM printers. We don’t repair, upgrade, or service resin/SLA machines — but we’re not anti-resin at all. In fact, we’re more than happy to help you figure out whether resin printing is the right fit for your needs. It’s a powerful technology with some amazing use cases — it just requires a different level of care, safety, and post-processing that doesn’t align with the types of clients we typically serve.

Let’s dive into the key differences so you can choose the best path for your printing journey.

How FDM and Resin Printing Work (Quick Primer)

Before we compare their strengths, it’s worth understanding how these two types of 3D printing actually work — because the process behind each one impacts everything from part quality to cleanup to overall user experience.

FDM (Fused Deposition Modeling)

FDM printers are the most common 3D printers you'll see in homes, schools, and makerspaces. They work by melting a plastic filament (usually PLA, PETG, ABS, etc.) and extruding it through a hot nozzle. The nozzle moves in layers — left to right, front to back — while the build platform lowers gradually. The part is built from the bottom up, one layer at a time.

FDM printers are known for:

• Their simplicity and reliability
• Low cost of entry and materials
• Being easy to tinker with, upgrade, and maintain
• Supporting a wide variety of materials for strength, flexibility, or heat resistance

Resin (SLA/MSLA/DLP)

Resin printers work in a completely different way. Instead of melting plastic, they use UV light to cure liquid resin layer by layer. The print is built upside-down on a platform that lifts out of a vat of resin as each layer is exposed and hardened.

Resin printers are known for:

• Incredible surface detail and precision
• Smooth finishes, perfect for miniatures, models, or molds
• A more complex workflow, including mandatory post-processing
• Requiring gloves, ventilation, and careful handling of toxic materials

Pros and Cons of Each Technology

FDM Printing – Pros

1. Low Cost of Entry
Basic FDM printers like the Ender 3, Prusa Mini, or Bambu A1 Mini are affordable and easy to start with. Filament is also inexpensive and widely available.

2. Easier Maintenance and Repair
FDM printers are mechanical and modular. If something breaks, you can usually replace the part with a screwdriver and a YouTube video.

3. Ideal for Functional Parts
Need a bracket, mount, jig, or enclosure? FDM handles strong, durable prints for real-world use — especially with materials like PETG or ABS.

4. Open-Source Flexibility
You can use dozens of slicers, mods, and settings. Most FDM printers support community-developed firmware and accessories.

5. Safer in Shared or School Environments
No harmful fumes, no resin exposure, and less risk of accidental chemical contact — ideal for classrooms and home offices.

FDM Printing – Cons

1. Visible Layer Lines
Even a well-tuned FDM printer may leave layer lines on vertical walls, especially at low resolutions or high speeds.

2. Limited Detail for Tiny Features
Fine text, miniatures, or micro-scale components are harder to print cleanly without major tuning.

3. Warping on Larger Prints
Long or flat prints may peel at the corners without careful bed leveling and temperature control.

Resin Printing – Pros

1. Exceptional Detail and Surface Finish
Resin prints can reproduce tiny features with near-mold quality precision. Great for miniatures, jewelry, dental work, or scale models.

2. Smooth Prints with Minimal Post-Sanding
Because of the way resin cures, the prints come out with smooth, curved surfaces that feel polished right off the build plate.

3. Compact Machine Size
Many resin printers have a small footprint and can sit neatly on a bench — but note that the cleanup station may take up just as much space.

Resin Printing – Cons

1. Messy and Hazardous Workflow
You’ll need gloves, paper towels, isopropyl alcohol, and a curing station. Spilled resin can damage surfaces and is harmful to skin and lungs.

2. Post-Processing Is Mandatory
Every print must be washed (usually in IPA) and UV-cured — adding time and steps that new users often underestimate.

3. Higher Operating Costs
Resin bottles, gloves, filters, disposable containers, and curing equipment add up quickly. Plus, resin has a shelf life.

4. Not Ideal for Shared Spaces
The smell, toxicity, and exposure risk make resin printing a poor fit for homes with pets, small children, or limited ventilation.

Cost & Maintenance Comparison

FDM: Affordable and Practical Long-Term

• Most quality entry-level FDM printers cost between $200–$700
• Filament costs $20–$30 per 1kg spool
• Maintenance is easy: clean nozzles, check belts, relevel the bed
• No special chemicals or safety gear required

Resin: Hidden Costs Add Up Fast

• Printer costs are similar, but operating costs are higher
• Requires consumables like gloves, IPA, paper towels, FEP film
• Needs a UV curing station and a safe post-processing area
• Hazardous waste handling is required for used resin and IPA

What Type of Projects Suit Each Method?

Choose FDM If You Want To:

• Print brackets, tools, functional housings, or enclosures
• Tinker, upgrade, or teach others how to use the machine
• Print in a classroom or home environment
• Spend less on materials and maintenance
• Use a wider range of materials like PLA, PETG, ABS, TPU

Choose Resin If You Want To:

• Print high-detail miniatures, models, or organic surfaces
• Create ultra-smooth parts with little post-sanding
• Work in jewelry, dental, or product design
• Have a dedicated, ventilated space for post-processing
• Are prepared to handle toxic materials and careful cleanup

Why We Don’t Service Resin Printers (And Why That’s Okay)

At 3D Printing by Bokey, we specialize in FDM printers — and we make that choice on purpose. Resin printing is powerful and capable, but it simply doesn't fit the needs of the communities we serve.

We primarily support New Jersey K–12 public school districts, home users, artists, makers, and small businesses. For these groups, FDM is:

• Easier to maintain
• Safer in shared spaces
• More reliable for functional, repeatable prints
• Cheaper to operate and scale

We don't handle resin printers because they require hazardous handling, niche parts, and careful disposal — all of which introduce cost, risk, and complexity that don't align with how our clients use 3D printing.

That said, we're not anti-resin. If you're not sure what to choose, we’re happy to help you make the call — even if the answer isn’t FDM.

FAQ – Resin vs. FDM Printing

Which is easier for beginners — resin or FDM?
FDM is easier and safer for beginners. Resin requires more equipment, chemical handling, and post-processing.

Can I print strong parts with resin?
Most resin prints are brittle. FDM is better for mechanical strength and load-bearing parts.

Are resin printers safe to use at home or around kids?
No — not without safety measures. Liquid resin is toxic and needs to be handled carefully in a controlled space.

What kind of ventilation do resin printers require?
You’ll need good airflow — open windows, fans, or enclosures with filters. Resin fumes can build up in enclosed areas.

Do I need a wash and cure station for resin printing?
Yes. It’s not optional — resin prints must be washed (usually in IPA) and UV cured before they’re safe to handle or use.

Conclusion

FDM and resin printers both have their place — but for most users, FDM is the better starting point. It’s safer, more affordable, and easier to work with on a day-to-day basis. Resin printing offers stunning quality, but at the cost of more maintenance, more cleanup, and more safety planning.

At 3D Printing by Bokey, we work exclusively with FDM printers because they’re the best fit for the people we serve — especially New Jersey schools, hobbyists, and makers. We don’t service resin printers, but we’re always happy to help you figure out if resin is right for your goals.
