What is SLS 3D Printing?

SLS (Selective Laser Sintering) is a 3D printing technology that uses a high-power laser to fuse powdered material (usually Nylon/PA12) layer by layer to create strong and functional parts. Unlike FDM, SLS does not require support structures because the surrounding powder supports the part during printing.

🔧 How SLS Works:

A thin layer of powder is spread on the build platform
Laser selectively fuses the powder as per CAD design
Platform lowers and new powder layer is spread
Process repeats layer by layer
Excess powder is removed after printing

⭐ Advantages of SLS

No support structures required

Strong & durable parts

Complex geometries possible

Good for batch production

What is MJF 3D Printing?

MJF (Multi Jet Fusion) is a powder-based 3D printing technology developed by HP. It uses a special fusing agent and detailing agent sprayed onto nylon powder, then infrared heat is applied to fuse the material layer by layer, resulting in parts with excellent mechanical properties.

🔧 How MJF Works:

A thin layer of nylon powder (PA12/PA11) is spread
Inkjet heads spray fusing & detailing agents
Infrared heat melts selected areas
Platform lowers and new powder layer is spread
Unfused powder is removed after printing

⭐ Advantages of MJF

High strength & durability

Excellent surface finish

No support structures needed

Fast production speed

What is DLP 3D Printing?

DLP (Digital Light Processing) is a resin-based 3D printing technology that uses a digital projector screen to cure liquid photopolymer resin layer by layer. Unlike SLA which uses a laser, DLP cures an entire layer at once, making it faster while maintaining excellent detail and accuracy.

🔧 How DLP Works:

Liquid resin is filled in a vat
Digital projector flashes an entire layer image
Resin hardens instantly
Platform moves up layer by layer
Final part is cleaned & UV cured

⭐ Advantages of DLP

Very high accuracy

Smooth surface finish

Faster than SLA

Ideal for small & detailed parts
