3D Printing

Published studies on new materials

In recent years, three-dimensional (3D) printing technology has rapidly grown, showing great potentialities that make it suitable for different research fields, from bioengineering and microfluidics/nanofluidics to electronics.

The manufacturing of 3D objects with stereolithography is based on the spatially controlled solidification of a liquid resin by photo-polymerization. In the last years the 3D printing DLP (Digital Light Processing) based has been recognized as one of the most powerful and versatile 3D printing processes thanks to its high fabrication accuracy and to an increasing number of materials that can be processed.

Recently a group of researchers from the Italian Institute TechnologyCSHRTurin (Italy) has published some scientific papers on the results from studies using our printer, 3DLPrinter-HD 2.0. These studies show that by coupling the 3D printing fabrication with a specific post printing treatment, it is possible to obtain highly reliable and precise 3D printed parts having a nano-phasic morphology where the organic phase is strictly interconnected with the inorganic one (hybrid materials).

The aim of these works was to implement a method for creating 3D printed complex hybrid objects, with enhanced mechanical propertie, exploiting a DLP machine coupled with a new material technique.

A 3DLPrinter-HD 2.0 (supplied by Robot Factory), equipped with a DLP projector with a resolution of 50 µm was used for the printing. The build area is 100 x 56.25 x 150 mm with a layer thickness adjustable from 10 µm to 100 µm. The printing process was followed by a post curing process performed with a medium-pressure mercury lamp also provided by Robot Factory.

In conclusion, studies have allowed to test, using our 3DLPrinter-HD 2.0, a hybrid (organic-inorganic) 3D printed structure. This method allows to build 3D structures with improved mechanical properties, using a full liquid formulation without the typical drawbacks of incorporating inorganic powders.
