How to Choose the Right 3D Printing Technology for Your Project

Not all 3D printers are created equal – and not every technology is suitable for your specific needs. In this article, we’ll explore the key differences between the most common 3D printing technologies and help you decide which one to choose – or when it’s better to rely on a professional service.

Why does the printing technology matter?

You might think: “As long as it gets printed, I’m good.” But the technology you choose impacts quality, strength, detail, and cost. Knowing what you need – and what’s available – can save you time, money, and frustration.

Overview of common 3D printing technologies

FDM (Fused Deposition Modeling)

The most common and affordable method. Thermoplastic filament is extruded layer by layer. We typically use PLA, PETG, ASA, PC or PA (with carbon fiber when needed).

Pros: Low cost, fast production, solid strength
Cons: Visible layer lines, limited precision, not ideal for small details

SLA (Stereolithography)

Liquid resin is cured with UV light, producing high-detail models with smooth surfaces.

Pros: Excellent detail, perfect for miniatures and jewelry
Cons: Fragile parts, higher cost, requires post-processing

SLS (Selective Laser Sintering)

Powdered material (usually nylon) is sintered layer by layer using a laser. No supports needed, and the parts are very strong.

Pros: High strength, no supports, ideal for functional parts
Cons: Expensive, industrial-grade equipment, longer lead times

MJF (Multi Jet Fusion)

An advanced process similar to SLS that delivers even better strength and accuracy.

Pros: Excellent mechanical properties, smooth and consistent finish
Cons: Only available through specialized services, higher price point

Which technology fits your project?

Prototypes and basic technical parts: FDM
Design models and miniatures: SLA
Functional mechanical parts: SLS or MJF
Outdoor use: FDM with ASA or PC for UV and heat resistance

Professional service vs. home printing

Home FDM printers can do a lot – but when it comes to precision, multi-color prints, large formats or demanding materials, it’s worth working with a professional 3D printing service.

Conclusion

Each technology has its pros and cons. The key to success is knowing what you expect from the print – and asking the experts if you’re not sure. We’ll gladly help you find the best solution for your project.
