What is 3D Printing

3D printing is a type of additive manufacturing technologies that produce three-dimensional solid parts one layer at a time from a 3D digital model,presented in the CAD design file or digital file,it is a layering method,and each layer can be considered as a thin cross-section of the object,using powders of metal,plastic, or other adhesive materials,which means the finished 3D printing part is a combinations of the powders,use powders of different materials and 3D printing machines to shape different objects and structures.

3D printing was offen used in mold manufacturing,cause it is so easy to print a hand mold with low cost and very a little time.And now we can find 3D printing widely used,like components in jewelry, footwear,firearms, industrial design, automotive,architecture, engineering and construction, dental and medical industries, education, GIS, aerospace,civil engineering, and other fields,normally we can print words and patterns with ordinary printers, however,with 3d printers,we can print objects and design concepts,even an idea can be easily realistic.

Materials

A wide variety of materials can be used in 3D printing,which makes the 3D printing parts much more bossibility,

Metals：Aluminum，Cobalt Chrome，Inconel，Stainless Steel，Titanium

Plastics：ABS，PA (Nylon)，PVA,Polycarbonate,PLA,CPVC,PEEK,Polypropylene，PP,PEI,PC,PMMA

Elastomers:Digital photopolymer，TPU，True Silicone，PETP

Applications

3d printing service & 3d printing parts applied in a variety of industries, such as telecommunications, aerospace, Medical instrumentation,Gears and bearings,Brackets,Fixtures for manufacturing,Internal mechanical components,Housings and enclosures,electric vehicle, UAV, robot, lightings,Form and fit prototypes,Surgical instrumentation,Medical devices,Jigs and fixtures,Engine components,Housings and enclosures,Snap fits,Fuel injectors,Heat exchangers and heat sinks.

Advantages of 3D printing

Multiple benefits have been provided by 3d printing,especially for prototyping customizing samples.

• Speed up a lot for prototyping or production process, dealing it within hours
• Support more complex geometries design and creation
• Save machines and operators,save labor,and save time
• Multiple materials are available
• Layer-by-layer assembling enhances the design with better quality
• Minimize the waste materials, with little or no waste compared to cutting machines
• The technology is environmentally-friendly and sustainable

SLA

Stereolithography (SLA) is a method using an ultraviolet laser to draw thousands of thin layers on the surface of liquid thermoset resin to form a part.

SLS

Selective laser sintering (SLS) means using a CO₂ laser to fuses nylon-based powder, layer by layer,building the final thermoplastic parts.

MJF

Multi Jet Fusion,means heating the nylon power materials bed,which are applied fusing and detailing agents,by heating elements,until a solid functional component formed.

FDM

Fused deposition modeling (FDM) is a method of heating, melting and forming various hot melt filamentous materials (wax, ABS, nylon, etc.)

Carbon DLS

Carbon DLS using digital light projection, oxygen permeable optics, and programmable liquid resins to produce plastic parts with excellent mechanical properties and surface finish.

DMLS

Direct metal laser sintering (DMLS),draw the atomized metal powder onto a surface using a fiber laser system,then weld the powder into fully dense metal parts.

Polyjet

PolyJet means the small droplets of liquid photopolymer are jeted from multiple jets onto a build platform and cured in layers that form elastomeric parts.
