3D Printing Pprocess

SLS

SLS fuses powdered material layer by layer using a laser, producing robust and durable parts. It’s excellent for complex geometries and end-use applications.

SLM

SLM melts metal powders with a laser to create high-strength, intricate metal parts. This process is ideal for aerospace, medical, and industrial applications.

SLA

SLA utilizes a laser to cure liquid resin into solid parts with high precision and smooth surfaces. Ideal for detailed prototypes and intricate designs.

HP MJF

HP MJF uses a fusing agent and heat to create strong, functional parts with fine details and excellent mechanical properties.
