The 3D printers really are a powerful engine for business growth and innovation processes of design, engineering and manufacturing of products in every areas.
The constant improvement of 3D printing technologies makes the use of additive manufacturing in production processes ever more advantageous.
Deciding on the best 3D printer for your requirements may not be easy and before proceeding with the purchase, you should have the opinion of an industry specialist who will advise the most suitable solution, probably expanding your prospect on usage opportunities that you did not have considered.

In this information we guide one to the decision by exploring the main 3D printing technologies and their peculiarities.
3D printing technologies
3D printers take advantage of the additive manufacturing process for the construction of the object from a 3D model created with three-dimensional CAD or obtained through a 3D scanner. The 3D printing technology varies according to the models: we see the main ones.
3D printers predicated on FDM technology , use a melted filament deposition (Fused Deposition Modeling) process for the construction of the object. Other additive manufacturing methods are much like FDM technology: fused filament fabrication (FFF), plastic jet printing, filament extrusion, fused filament deposition, material deposition.
3D systems based on this technology continue to be the most used and accessible. These are 3D printers that cover a wide variety of applications and offer both economic models, suitable for’consumer’users, and industrial solutions for 3D production made for companies and service centers that want high performance machines.
The FDM 3D printers build objects by depositing layers of thermoplastic material in the filament which will be heated and extruded through a nozzle, to replicate the geometry of the 3D model to be printed. The 3D printing material most commonly employed by the FDM 3D printer is ABS.
3D production printers with FDM technology (such because the Stratusys Fortus 450 ) can make use of a wide variety of thermoplastic materials, including standard plastics (eg ABS) to high-performance plastics with specific properties in terms of of mechanical resistance, electrostatic dissipation, biocompatibility, UV resistance, thermal resistance. On the list of FDM printers you can find 3D systems particularly suitable for aeronautical, aerospace and medical applications and for the production of tools for the production line.
The PolyJet technology is especially valued for its ability to produce 3D models with exceptional realism. Other 3D printing technologies similar to this are multijet printing and photopolymer jetting. A PolyJet 3D printer works conceptually much like a regular inkjet printer, with the difference that as opposed to the ink it uses liquid photopolymers and as opposed to paper there’s a printing plane on that your drops of resin through the action of UV light. The solidification of successive layers of material contributes to the construction of the object.
