Plastic molding: what are the advantages with 3D printing?

The 3D printers certainly are a powerful engine for business growth and innovation processes of design, engineering and manufacturing of products in most areas.

The constant improvement of 3D printing technologies makes the utilization of additive manufacturing in production processes ever more advantageous.

Choosing the right 3D printer for your requirements may possibly not be easy and before proceeding with the purchase, you need to feel the opinion of an industry specialist who’ll advise the most suitable solution, probably expanding your prospect on usage opportunities that you did not need considered.

In this short article we guide you to the choice by exploring the key 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 in line with the models: we see the key ones.

FDM technology
3D printers centered on FDM technology , work with a melted filament deposition (Fused Deposition Modeling) process for the construction of the object. Other additive manufacturing methods are just like FDM technology: fused filament fabrication (FFF), plastic jet printing, filament extrusion, fused filament deposition, material deposition.

3D systems based with this technology continue to be the most used and accessible. They’re migliore stampante 3d professionale 2019 that cover a wide variety of applications and offer both economic models, ideal for’consumer’users, and industrial solutions for 3D production designed for companies and service centers that want powerful 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 utilized by the FDM 3D printer is ABS.

3D production printers with FDM technology (such while the Stratusys Fortus 450 ) can work with a wide variety of thermoplastic materials, ranging from standard plastics (eg ABS) to high-performance plastics with specific properties in terms of of mechanical resistance, electrostatic dissipation, biocompatibility, UV resistance, thermal resistance. Among the FDM printers there are 3D systems particularly ideal for aeronautical, aerospace and medical applications and for the production of tools for the production line.

PolyJet technology
The PolyJet technology is particularly valued because of its ability to produce 3D models with exceptional realism. Other 3D printing technologies such as this are multijet printing and photopolymer jetting. A PolyJet 3D printer works conceptually just 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 publishing plane on that the drops of resin through the action of UV light. The solidification of successive layers of material results in the construction of the object.
