3d modelling - Import export

Based on your ideas and in close collaboration with your specialists, PRUFREX takes part in the development of your new products. In the shortest possible time, we are able to supply you with individually produced prototypes and functional models. We use 3D printing technologies to efficiently produce mechanically functional device models. We know how important functionally correct sample products are in the early phases of your product, as are impressions of the look and feel of the device as a whole.

With laser generation, components are built up layer by layer from powdered metallic materials used in serial production such as 1.2709 steel or 1.4543 steel. Thanks to state-of-the-art technology, this enables us to transfer your computer-generated 3D/CAD models reliably over to their physical form. Here, thin coats of the powder materials are applied to a base object before being melted using a laser into the desired contour. This process is continued on a revolving basis until the workpiece is complete with the final geometric form and the relevant functional properties. Incidentally, we reclaim excess powder material during this process and use all of it for later productions again. Our services in sample development also include technical springs, which we produce in small batches for your sample application. Traditional sample development services are a new addition to our portfolio. Here, we produce a small-scale series of your bent strip parts from original materials.

The surfaceCONTROL 3D 2500 snapshot sensor is used in 3D measurements for geometry, shape and surface inspection on diffuse reflecting surfaces. The sensor can be used in both automated in-line and at-line inspections as well as in the metrology room. The fringe light projection allows direct 3D measurement. The sensor is characterized by its large measuring field as well as a high measuring range depth of up to 300 mm with a repeatability of up to 3.0 µm. The captured images are transferred to the external controller where they are processed into 3D data. Three models cover different measuring fields.

4D_Additive reads all common CAD-formats with the PMI and processes them as an exact B-Rep geometry. Hereby makes it possible to test, repair and prepare the 3D-models according to the CAD engineering standard. The software has innovative features such as 3D-nesting, collision checking and distance control for automated and safe assembly of the installation space. The dynamic roughness analysis can be used to determine the optimal alignment of the components in order to generate the best possible surface. Another module is to generate automatic support geometry, which is necessary for SLA or SLM. The innovative Texture Module, allows the user to access more than 5,000 different texture surface structures. With the latest version of the 4D_Additive Software Suite, we presenting a new batch tool for a fully automated, fast and reliable nesting.
