1. 3D SYSTEMS THERMOJET PRINTER 3D Printing (3DP) was developed by MIT; licensed to several companies including Soligen Corp and others. Multi jet modeling was developed by 3d systems in 1995. The MJM machine was marked as the Actua 2100 but since 1998 it has been known as the Thermo jet printer. Thermo-jet has multiple ink-jet heads, which allow it to deposit and entire layer in one pass. This allows for true rapid model production

Ink-jet printing head deposits a fluid to fuse Inkpowder material. Unbound powder remains to support the part. The platform is lowered as more material is added and the process continues its future cycles. Part are the removed from machine, unbound powder removed and part continues postpostprocess.

produce extremely fine resolution and surface finishing; as good as CNC machining allow designers to effectively communicate design intent to others - other designers The Thermo Jet printer overcomes the limitations of 2D simulations, which do not fully convey design intent and require a technical understanding of how to interpret such drawings or screen views

The Thermo Jet printer's automated build process can supply this model in a few hours, compared to days or weeks for traditional modelmaking processes.

   ` `

`

`

Relative long build time After the build, the part is enclaved inside a wax block and is required some solvent to dissolve wax Currently, only one proprietary thermoplastic material is available which limited the application of the process Because of the low speed and the size of the working envelop, it is not appropriate for large parts

CASE STUDY : JEWELLERY INDUSTRY In these cases by switching to Rapid prototyping machines you can expect to significantly reduce production time and cost for the completion of any project. The process works by using ArtSTL to convert any of your existing Art CAM relief files, (including wrapped rings), into Stereo Lithography (STL) format. The STL file is then transferred over to the Rapid prototyping machines (or 3D printer). Model master have found that the 3D Thermo jet from 3D Systems is a fast low cost solution for producing these. The Thermo Jet has a ´printerµ head producing a flow of hot wax built up layerlayer-by by--layer and in a matter of minutes gives you an accurate wax model of your Art CAM relief.

2. Sander Model Maker II The Sander Model Maker product is produced and distributed by Sanders Prototype, Inc. of Wilton, NH, USA. It was developed in 1994 Ink jet printing comes from the printer and plotter industry where the technique involves shooting tiny droplets of ink on paper to produce graphic images. RP ink jet techniques utilize ink jet technology to shoot droplets of liquidliquid-to to--solid compound and form a layer of an RP model

3. THREETHREE-DIMENSIONAL PRINTING

The three-dimensional printing (3DP) process was invented and patented by the Massachusetts Institute of Technology and licensed to Z-Corporation in 1994.the first system ,the Z402 was commercialized in 1996

|  Import your 3D data file into our ZPrint software, and position as desired. The system automatically checks printer readiness and material stores, ensuring you always have the right amount of material to complete the job.  If supplies do need to be replenished, simply insert a oneone-liter binder cartridge, connect a powder canister for automatic loading, or snap in a new print head.  Click "3D Print" and watch 3D model emerge from the bottom up one crosscross-section at a time. A new, expanded status display keeps you apprised of the machine and job status.

 When printing is complete, a vacuum and vibration system automatically removes as much as 80% of loose powder ² and recycles it for future use.  Remove the remaining powder with lightly compressed air, in a fully enclosed chamber that vacuums away powder as you go. Unlike other systems, there are no physical support structures to remove with scraping tools.  Finish and strengthen your model by dipping in ZZ-Bond sealant, dripping ZZ-Bond over model, or lighting brushing with ZZ-Max 
a strong, brilliant color 3D model. Fast. In fact, this model was printed and finished in less than four hours.

4. STRTASYS GENISYS PRINTER The process was developed by IBM and is similar to fused deposition modeling in January 1995, stratasys purchased this RP technology from IBM

The Genisys Xs 3D printer is a conceptual modeler. It produces high-quality models from a high-strength polyester compound . The models are ready to use right from the printer

5. JP SYSTEM5 The JP system 5 is patented by Schroff Development Corporation. it is an inexpensive RP system that requires only a personal computer and a cutting device. The system produces prototypes using paper sheets and so the material cost is very low

| `

`

`

`

A proprietary software package is used to slice the model into a series of cross sections The software then converts the slices to a HPGL plot file format which is sent to a plotter The sheets are layered by aligning specially cut orientation holes The sheets are positioned on a registration board

| ` `

`

`

An adhesive is sprayed on the first sheet The support backing is removed exposing the adhesive layer. Each subsequent sheet adheres to the exposed adhesive surfaces of the previous sheet Sections formed by the nesting operations are cut The final model is assembled

6. OBJECT QUADRA SYSTEM Object Geometries Ltd was founded in 1998 to develop a RP system that employees state-of-art inkjet technology and a proprietary photopolymer.

The company shipped the first system called Object Quadra in 2001

| `

`

`

The Object Quadra Tempo process is based on Object's statestate-ofof-thethe-art Poly Jet polymer jetting technology. It uses 1,536 nozzles to jet layer upon layer of 20 microns (0.0008"). Each layer is printed by the jetting of model and support material an ObjectObject-developed photopolymer, with each layer cured by exposure to UV light For models with undercuts and overhangs, the Quadra deposits support material made of a photopolymer designed for easy removal.
