Thanks to the corporate know-how in the design, we develop projects dedicated to customer needs:
> 3D CAD Modeling: Feasibility study and modeling support with the most advanced software, we carry out
parametric modeling of complex elements, conversion of files from 2D to 3D, development of mechanical projects, creation of all the technical documentation starting from the construction tables up to the use and maintenance manuals.
> Topological optimization and simulation by F.E.M .: We produce reliable and durable products, taking into account the forces and factors constraints to which the element will be subjected and the required performances. The models are optimized to eliminate the percentage of un-necessary material while maintaining functional and aesthetic requirements, design geometries that
improve the physical and mechanical characteristics of the products with important advantages in terms of weight reduction, number of components and assembly times.
> Reverse engineering: We replicate pieces of all shapes and we print them in 3D. You can also reproduce pieces that are no longer available on the market (for example objects out of production) or replace metal and plastic components obtained with traditional technologies.
With a machine fleet of high productivity and in continuously expansion, we quickly print using the most advanced technologies:
SLS Selective Laser Sintering: Powder bed production process. A container of polymer powder comes
heated to a temperature just below the melting point of the polymer. Subsequently, a blade deposits a very thin layer of the powdered material – typically 0.1 mm thick – on the construction platform. A laser beam scans the surface and selectively sinters the powder to ensure that the part is completely solid through a cross-section of the desired component. When the layer is complete, the construction platform moves downwards and the blade deposits another layer of dust and the laser performs sintering, the process is repeated until the desired object is completed. The molded part is encapsulated inside the block of non-sintered powder, this powder, which also acts as a structural support, is collected and recycled.
DLP/SLA For high-definition printed resin elements.
A projector radiates with a single pulse the resin layer, hardening simultaneously and selectively all the points belonging to the same layer. Through
the addition of new layers of resin and selective exposure to light, all levels are hardened up to complete the
object. This technique is suitable for the production of elements with high resolution, accurate to the smallest detail with the smoothest surfaces.
It allows to produce isotropic parts with equal hardness and strength characteristics in all axes. DLP/SLA technology is suitable for the production of very complicated and small pieces, for the rapid production of many small objects in a single plate, or of large parts that have tiny surface details. The variety of materials and the high degree of detail make this technology ideal for modeling, jewelery designs, dental and biomedical sector.
FDM Fused Deposition modelling. A plastic filament is unrolled and extruded from a heated nozzle, the thermoplastic material is deposited on the printing platform where it solidifies. The construction of the model takes place through a stratification process, from bottom to top to form the final object. A forced ventilation system allows to
maintain a constant temperature and helps the solidification of the material. Subsequently another layer is extruded
and the deposited material melts and binds to the underlying layer. Depending on the forms to be made, they come
appropriately dosed with the supports, which at the end of the process are removed with specific detergents and water. With the FDM it is possible to use thermoplastic materials with high mechanical, thermal and chemical resistance and to create components with complex geometries and articulated cavities.
MJF, Multi Jet Fusion. Technology developed by HP and based on the use of polymers in powder (PA 11, PA 12 and PA 12 loaded with glass). The printing process begins with the laying of a thin layer of material in the processing area, the powder bed is uniformly heated and worked thanks to the addition of 2 agents, the fusion agent and the detail agent. The first is applied at the points where it is necessary to selectively melt the powder, while the detail agent is deposited to define the details in the contours. Mobile lamps, positioned on the powder bed, distribute the necessary heat for fusion. Combining the stratification phase of the agents with the fusion process, we arrive at
product completion. The dust bed acts as a support to the structures and no steps are required to remove
the support, this feature, together with the high definition of the finished product makes it necessary to have a minimal post-production phase. With this technology it is possible to realize thin layers up to 80 microns, with accuracy in details and
A large post-production area is dedicated to surface finishing and assembly services. Depending on the needs of the customer, the printed elements will be subjected to surface finishing processes (sandblasting or tumbling), painting or coating with composite fibers, depending on customer requirements.
