For ONEOFF the true raw material is a 3D file from which every technology, material and result is possible.
ONEOFF realizes architectural and urban planning models of any size, complexity and material starting from a 3D file preferably provided by the client.
If required, our team can offer the realization of the three dimensional modeling.
The mix of techniques and materials means that highly original and interesting results can be obtained, with a high level of precision when production time is at a premium.
We invite you to view the images of the architectural models realized.
TECH Rapid Prototyping (RP)
Want to save time and money during the design stage?
Want to reduce the number of prototypes needed?
Want to reduce costs due to errors at the design stage?
Rapid Prototyping (RP) is an innovative technology that allows the production of objects of complex geometry in just a few hours without using tools, directly from the mathematical model of the object made using a three dimensional CAD system.
It is useful for making:
- Styled objects to check the design
- Physical prototypes, to check that the parts fit together
- A master for creating moulds
During the development phase of a product the following types of prototypes are made:
- Conceptual models
- Prototype for validation
- Technical prototype
- Final pieces
Various techniques exist for making prototypes (3D Printing, Selective Laser Sintering, Stereolithography). All these techniques work on the notion of layers, they differ from each other mainly in terms of the materials used, the physical principles exploited and the purpose of the prototype.
And the human touch?
When working with Rapid Prototyping techniques, the professional know-how and support is applied in two distinct phases: pre-production and post-production.
During pre-production the CAD file is evaluated, and the geometry of the mathematical model checked. The time required for this process is difficult to quantify beforehand as it depends totally on the software and the precision with which the mathematical model has been generated. The model is translated into an STL, which describes it as a mesh of perfectly closed triangles (a kind of skin that covers the entire volume of the object). The mesh must not have holes, overlaid triangles or be made of triangles that are too big, making curved surfaces come out faceted. It is necessary that the files are checked by experts in the use of a wide range of 3D modellers and skilled in identifying any anomalies.
Fundamental in this operation is the scaling of the piece to obtain a prototype with the desired tolerances.
Not to be underestimated is the nesting (positioning in the machine) in order to create an object with the best possible shape and structure.
In the postproduction phase the model undergoes operations of drying, resin treatment, smoothing and other surface treatments that may be needed. In this phase the more traditional model making experience of the skilled artisan is required.
