  Direct-Digital
Manufacturing (DDM)
 
Direct Digital Manufacturing (aka rapid manufacturing) is improving the productivity and profitability of many companies around the world. Direct Digital Manufacturing is an extension of Rapid Prototyping that produces greater quantities of parts. DDM can be used to build your projects in a fraction of the time and cost associated with traditional manufacturing processes.

   
 
     
 
 
  Fused Deposition
Modeling (FDM)
 
Fused Deposition Modeling [FDM] turns a 3-D CAD design into a functional ABS plastic prototype to be used in testing and fitting. Fused Deposition Modeling is a solid-based rapid prototyping method that extrudes material, layer-by-layer, to build a durable and strong model. This method of rapid prototyping is the most economical method to produce plastic prototypes and abs models.

   
 
     
 
    Selective Laser
Sintering (SLS)
 
SLS is very similar to the SLA (stereolithography) prototyping process but is more detailed and can make flexible parts like living hinges. It's best to use SLS, when requiring complex shapes that closely resemble injection molded parts or if you require flexible parts. The process of a SLS machine, uses a computer controlled laser to sinter (melt) a thermoplastic powder, layer by layer, to create a three dimensional part.

   
 
     
 
    Stero lithography
Prototype (SLA)
 
Stereolithography (SLA) provides accurate models and patterns in record time. A stereolithography apparatus (SLA) uses a computer controlled laser to cure a liquid photo-curable resin, layer by layer, to create a 3D part. SLA models are ideal for use as concept models, form and fit and are also used as master models.

    Polyjet
 
Poly Jet is similar to stereolithography because the parts are made with a photosensitive resin. The difference is in how the resin is applied and cured to build the part. Poly Jet technology uses a jetting head to accurately build each layer at 16 microns (0.0006 inches) thick, which is about 1/5 that of stereo lithography layers. Because of this super thin layer, the parts are very accurate and produce a very smooth surface finish.
