Online Rapid Prototyping Service

3D Printing Service

Our online 3D printing service enables you to 3D print your custom part on demand. We offer five 3D printing technologies to transform your 3D files into plastic, metal, and elastomeric parts. With more than 100 3D printers, we have unmatched capacity that reliably delivers parts within days. In addition to a broad material selection, we offer several post-processing options to improve cosmetics or enhance mechanical properties.

SLA 3D printing service

Stereolithography (SLA) uses an ultraviolet laser that draws on the surface of liquid thermoset resin to create thousands of thin layers until final parts are formed.

SLS 3D printing service

Selective laser sintering (SLS) uses a CO2 laser that fuses nylon-based powder, layer by layer until final thermoplastic parts are built.

MJF 3D printing service

Multi Jet Fusion selectively applies fusing and detailing agents across a bed of nylon powder, which are fused in thousands of layers by heating elements into a solid functional component.

DMLS 3D printing service

Direct metal laser sintering (DMLS) uses a fiber laser system that draws onto a surface of atomized metal powder, welding the powder into fully dense metal parts.

CNC Machining Service

Rapid prototyping via CNC machining delivers high speed, high precision, and robust rapid part manufacturing solutions. You take a block or billet of material and cut away at it with a series of tools and drill bits, removing material to make CNC machined parts or products.

CNC MILLING

CNC milling cuts shapes out of a metal or plastic material blank that is usually flat, holding dimensions to tolerances as tight as 0.002.

Metal parts processing services

Magnesium alloys are alloys based on magnesium and composed of other elements.
Features: small density, high strength, large elastic modulus, good heat dissipation, good shock resistance, greater impact load capacity than aluminum alloy, good corrosion resistance to organic matter and alkali. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors.
