Custom Metal 3D Printing Services

Metal 3D Printing is an additive manufacturing technology that melts metal powder layer by layer using a high-energy source, solidifying it into a dense metal object.This process produces metal parts with excellent mechanical properties, widely used in Aerospace, automotive, medical, and industrial equipment fields.
Compared to traditional CNC machining or metal casting, Metal 3D Printing preserves metal strength and durability while giving designers greater freedom.It can form complex internal structures, lattice topologies, and geometries difficult to achieve with traditional subtractive processes, opening new possibilities for lightweight design, functional integration, and personalized manufacturing.

Direct Metal Laser Sintering (DMLS), also known as Selective Laser Melting (SLM), uses high-energy lasers to scan and fully melt metal powder layer by layer, building high-density metal parts from bottom to top.The Core Advantages of this process lie in its ability to form fully dense metal structures, suitable for Applications with strict sealing and strength requirements like fluid channels and heat exchange components.
DMLS supports various common alloys including aluminum-silicon alloy (AlSi10Mg), 17-4 stainless steel, 316L stainless steel, and high-performance materials like Inconel and maraging steel.Although DMLS has higher per-unit costs than binder jetting, its forming precision and mechanical properties are superior, suitable for fields like Aerospace, medical implants, and High Precision industrial components.

Metal binder jetting is a multi-step forming process. First, print heads selectively deposit binder on the metal powder bed surface, bonding powder particles into a 3D blank; the formed "green part" undergoes curing treatment, then enters a sintering furnace for high-temperature densification, or strength enhancement via copper infiltration.Since the powder bed provides natural support for overhanging structures during forming, binder jetting requires no additional support structures, greatly simplifying post-processing workflows.
The Core Advantages of this process are fast print speeds and low forming costs, suitable for low-volume production of small-to-medium sized parts.Sintered metal parts can reach 95%+ density with good mechanical properties, suitable for functional prototypes and end-use components.Additionally, binder jetting has found wide applications in art design, customized consumer goods, and scientific research education due to its controllable costs and flexible forming.
Note that binder jetting parts undergo uniform shrinkage during sintering. Design stages should follow Design for Manufacturing (DFM) principles with pre-compensation of model dimensions (typically 1-2% reduction) and corresponding adjustments to hole diameters and feature sizes.
