What We Excel At in 3D Printing

Advanced technology and expert skills to brings your ideas to life through high-precision, quality-assured 3D printing services

SLS(Selective Laser Sintering)

The SLS technology means that the selective laser will irradiate the material powder, and make the special additive material melted. These special additive material will become the binder, and make the metal powder combined and formed to expected 3D model. Then the metal 3D printing will be completed.

Fused Deposition Modeling (FDM)

FDM uses thermoplastic filaments to create durable, functional parts. Ideal for rapid prototyping and low-cost production, FDM supports materials like ABS, PLA, and PETG, suitable for automotive components and consumer goods.

Stereolithography (SLA)

SLA employs a laser to cure resin, producing parts with exceptional surface finish and fine details. Perfect for intricate prototypes, medical models, and jewelry, SLA achieves high accuracy for complex designs.

SLM (Selective Laser Melting)

SLM is using a high energy and fine spot laser. Parts not only have precise dimension, high tensile and high density, but also excellent in mechanical properties. Mainly used for rapid production of high-precision, high quality metal parts.

Direct Metal Laser Sintering

DMLS builds metal parts by sintering metal powders, such as titanium and stainless steel, for high-strength applications. Used in aerospace, medical implants, and automotive, DMLS supports complex geometries with excellent mechanical properties.

Multi-Jet Fusion (MJF)

MJF delivers high-speed production of precise, durable parts with uniform mechanical properties. It’s suited for functional prototypes, small-batch production, and parts requiring consistent strength.
