|Technology||Two wax ink-jet processes: Drop on demand and smooth curvature printing||Paper-based||Fuse deposition modeling||Inkjet 3D printing
||Polyjet matrix resin-based ink jet printing||Plastic jet printing||Film transfer imaging
|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
|Application(s)||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.

|Color support||No||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.||No||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.
|Build material||Wax compound||Paper||ABS plastic||Mix of plaster or gypsum-like ingredients with some polymer added||Acrylic-based photopolymer resin||ABS, polylactic acid (PLA)||Proprietary material
|Support material||Wax compound with lower melting point than build material||Paper||Water-soluble plastic||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
|Post-processing||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.
