|How it works
||Two materials are jetted simultaneously to produce layers that form the 3D object.
||Builds 3D object by alternating layers of ordinary printer paper and adhesive; tungsten carbide blade automatically cuts away excess material that is removed using fingers or tweezers; waste material also supports the object as it's being built.
||Melts ABS plastic fillament and applies the melted material using an extrusion head to build up the 3D object in layers. The melted layers fuse together as they are added.
||A thin layer of powder is spread across the surface area; inkjet print heads then deposit a liquid that binds the powder, creating the layers that form the 3D object. The powder layers provide support for the object.
||Printer jets a liquid resin and uses a UV light to cure it.
||Melts and extrudes filament layers of plastic that fuse together as they cool.
||Applies layers of resin, which cures using UV light emitted from a modified digital light processing (DLP) slide projector.
|Primary attributes of the technology
||Very precise, high-quality surface finish; wax melts away easily for mold creation.
||Green technology: Waste paper is recyclable and water-soluble glue is eco-friendly. Offers smooth finish without sanding or other post-processing.
||Durable ABS plastic, good surface finish.
||Full color printing, relatively fast with low operating cost.
||Can use a range of materials from rubber-like material to polyprolylene-like material or blends. Can have rigid or soft material in the same part.
||Fast, affordable, color, ABS material relatively strong.
||Excellent quality, smooth surface finish
||Models used to make castings for jewelry making or other parts that require a high-precision surface finish.
||Architectural renderings, medical, dental models.
||Building design models and prototypes for visualization or testing. Production of one-off or very limited production run parts.
||Building design models and prototypes; some custom, one-off or low-volume manufacturing. Suitable for concept models and some functional testing.
||Prototypes for fit form and function verification. Dental, automotive, medical, consumer electronics/consumer goods, industrial manufacturing.
||Education, hobby, do-it-yourself.
||Building design models and prototypes for visualization or testing.

||Can use any color paper; can vary color in an object by using different colors in the paper stack.
||8 colors on uPrint Plus. Ivory only for uPrint. DesignJet 3D supports 9 colors. One color per print job.
||Can produce full-color parts; multiple colors per print job.
||Supports a wide variety of different colors but allows only one per extruder or print head. Can make a two-color part.
||Supports up to 6 colors, one with an increased build speed, one color per part.
||Mix of plaster or gypsum-like ingredients with some polymer added
||Acrylic-based photopolymer resin
||ABS, polylactic acid (PLA)
||Wax compound with lower melting point than build material
||Object supported by layers of reusable waste powder surrounding the object
||A gel-like material that can be washed away with warm water
||PLA and soluble, translucent PLA
||Same as build material
||Completed object inserted into a warm liquid solution that dissolves the support material (melting point 122 degrees F) without melting the build material (melting point 212 degrees F).
||Very short. Excess paper can be pulled away with fingers.
||Finished object must be transferred to a warm water bath that dissolves the support material. The system requires a water feed and drain. Total post processing time: About 2 hours.
||Object inserted into special station where a technician uses a small air gun is used to remove excess powder, a fine brush to finish. The object may then be soaked in a clear resin or glue solution to add strength and brighten the finish.
||Uses high pressure water to wash away residue. Typically takes less than 10 minutes.
||Remove supporting material by breaking off or soaking in warm water for 48 hours. Requires light sanding.
||Wash and remove supports.
