3D Modeling and Product Design

3D modeling, in computer graphics, is the process of defining a three-dimensional shape in a virtual space generated on a computer. These objects, called 3D models, are created using specific programs called 3D modelers or more generally, 3D software. Our designers, using these modern and up-to-date softwares, can transform your designs (even hand-drawn ones) into digital 3D models.

Reversal Engineering

Reverse engineering is a process aimed at identifying the properties of a physical object through a comprehensive analysis of its structure, functions, and operations. Measurements of the geometry of the entire surface of the object are taken, either manually or using various 3D measurement technologies, to then create a digital 3D representation of the object. Therefore, if you have an object to replicate for which you have no 2D and/or 3D drawings, through reverse engineering, we can quickly and faithfully create a 3D model of it.

FEM Analysis

FEM simulation is similar to what happens on a test bench. The difference is that tests are conducted on a virtual prototype, i.e., a CAD geometric model, to which specific material with known mechanical characteristics is assigned. Therefore, FEM analysis allows us to predict the behavior of the object during its operation. Understanding the critical points and consequently modifying the component in a way that prevents issues from arising.

With FEM analysis, we also gain advantages in terms of time:

  • It reduces the number of physical prototypes, consequently lowering the costs associated with product development.
  • The time to market is reduced because in the virtual environment, modifications to the geometry take only a few minutes.


Rapid prototyping is a set of industrial techniques aimed at the physical realization of the prototype in relatively short times, starting from a three-dimensional mathematical definition of the object (3D drawing). Today, there is a wide range of prototyping processes to choose from.

There are different ways to create a prototype:

Metal replacement

Metal Replacement is a technology that allows the conversion of components, traditionally made of metal or metal alloys, into new parts by rethinking and reengineering them, using high-performance plastics, super-polymers, and reinforced technopolymers. Technopolymers combine the positive aspects of metal, such as its high mechanical properties, with the advantages of polymers, including melt integration, corrosion resistance, and other aspects listed below.

Economic Benefits:

  • Few or no secondary operations
  • Ease of production
  • Complex geometry
  • Article consolidation
  • Greater number of parts per mold

Performance Benefits:

  • Improved tribology (study of friction, wear, and lubrication)
  • Total product weight reduction
  • Resistance to corrosion and chemical agents
  • Noise reduction

Aesthetic Benefits:

  • Infinite possibilities for coloring and color combinations
  • Improved ergonomic design
