FDM vs SLA vs SLS: Choosing the Right 3D Printing Technology in Bangalore
If you’re in Bangalore and looking to bring your idea to life with 3D printing, you’ve probably
come across terms like FDM, SLA, and SLS. But for someone new, these terms can feel
confusing. Each technology has its own strengths, weaknesses, costs, and best-fit applications.
This blog is written to help students, startups, researchers, and businesses in Bangalore
understand the difference between these three technologies — and more importantly, to guide
you in choosing the right one for your project.
1. FDM – The Affordable and Accessible Option
What is FDM?
FDM (Fused Deposition Modeling) is the most widely used 3D printing technology in
Bangalore and across the world. It works like a high-tech glue gun: thermoplastic filament is
heated, extruded, and deposited layer by layer to form the part.
Why is it popular?
Because it’s affordable, simple, and fast, FDM is the first choice for:
- Engineering education printing project parts.
- Startups making early prototypes.
- Schools and DIY makers experimenting with 3D printing.
Pros
- Low cost – ideal for budget projects.
- Wide material choices – PLA, ABS, PETG, TPU, Nylon.
- Fast prototyping – parts ready within hours.
Cons
- Visible layer lines (rough surface).
- Lower accuracy compared to SLA/SLS.
- Limited strength for high-performance parts
Bangalore Use Case Example
At RV College of Engineering, students often use FDM printers for robotics projects —
printing lightweight parts for drones or robot arms.
- Cost in Bangalore: ₹5 – ₹15 per gram (depends on material and finishing).
2. SLA – The Artist of 3D Printing
What is SLA?
SLA (Stereolithography) uses liquid resin cured by a laser or light source. This results in
extremely fine details and smooth surfaces — much better than FDM.
Why is it special?
SLA is chosen when precision, aesthetics, and detail matter more than cost. That’s why it is
popular in medical, dental, and jewelry sectors in Bangalore.
Pros
- High precision & detail – perfect for complex designs.
- Smooth surface finish – requires little post-processing.
- Variety of resins – castable, transparent, flexible.
Cons
- More expensive than FDM.
- Resins can be brittle.
- Needs cleaning and UV curing after printing.
Bangalore Use Case Example
Jewelry design houses in Commercial Street and Richmond Town use SLA to create intricate
ring and bangle prototypes, which are later cast into gold or silver.
Cost in Bangalore: ₹15 – ₹25 per gram (resin type matters).
3. SLS – The Powerhouse for Industry
What is SLS?
SLS (Selective Laser Sintering) uses a high-powered laser to fuse powdered materials (usually
nylon). Unlike FDM and SLA, SLS doesn’t need support structures, because the surrounding
powder holds the object in place.
Why is it powerful?
SLS is the go-to for industrial applications where strength, durability, and complex geometries
are required. In Bangalore’s aerospace and automotive sector, this technology is gaining strong
adoption.
Pros
- High strength & durability – functional, end-use parts.
- No supports needed – print any complex shape.
- Good for low-volume production.
Cons
- Higher cost than FDM/SLA.
- Surface finish is grainy (needs polishing).
- Requires expert handling and post-processing.
Bangalore Use Case Example
A startup in Whitefield’s EV cluster uses SLS to prototype battery enclosures for electric
scooters — parts that need strength, accuracy, and durability.
Cost in Bangalore: ₹20 – ₹35 per gram.

How to Choose the Right Technology in Bangalore
- Students & Hobbyists → Choose FDM for cost-effective, quick models.
- Designers, Dentists & Jewelers → Choose SLA for high-detail prototypes.
- Industrial Clients (Aerospace, Automotive, EV, Robotics) → Choose SLS for durable and functional parts.
3D Paradise – One Destination for All 3D Printing
Technologies in Bangalore
When it comes to choosing between FDM, SLA, and SLS, most companies or students in
Bangalore struggle with two things:
1. Lack of access – Either they find only one technology with a local vendor.
2. Lack of guidance – Vendors just ―print what is sent‖ without advising whether it’s the right process.
That’s where 3D Paradise is different.

At 3D Paradise, we have invested in a complete suite of 3D printing technologies:
- FDM for low-cost, quick, and large-volume prototypes.
- SLA for high-resolution resin models (medical, dental, jewelry, and design).
- SLS for strong, industrial-grade, and functional nylon parts.
You don’t need to run to different vendors — everything is available in one place.
2. Support for Every Stage of Your Project
We don’t just provide printing — we provide end-to-end support:
- 3D Scanning & Reverse Engineering – Convert physical objects into digital CAD files.
- Design Optimization – Our engineers help adjust your model for cost savings and printability.
