SLM – Selective Laser Melting
The data for printing is suitable to deliver in a formats: STL, STEP, SAT, X_T, X_B
Technology Selective Laser Melting (SLM) enables the production of unique parts, prototypes and test samples with complicated geometry or internal structure, which are difficult to produce by conventional technologies. The part is formed by successive deposition of thin layers of metal powder which are sintered by a laser beam. The process produces homogenous metal parts directly from a 3D CAD data. Construction parts take place in an inert atmosphere of N2, making it possible to declare the purity of the processed material.
The deposition of each layer of the material is achieved with a 99.9% fill factor. The SLM 280 HL processing system enables a wide range of metallic materials such as stainless steel, tool steel, cobalt-chrome or super alloys. Furthermore, devices operate under inert argon atmosphere to enable the processing of reactive metal powders such as aluminium and titanium alloys.

3D optical digitisation
Meeting the demands of the industry in the field of optical digitisation of real objects and Reverse Engineering, the digitisation of objects is possible from several millimetres to several meters. In addition to the digitization process the team offers geometric tolerances, generate primitives derived from the scanned data, compare different scans or CAD data using maps and other variations. For use in design practice we perform reverse engineering of scanned data, we convert the polygonal models on desktop or on the volume geometry. The reconstructed model can be loaded into standard CAD applications, or you can create a specific model in CAD.

Reverse engineering (RE) using 3D digitization is the most efficient way to generate a CAD model from a physical object with a complex or freeform shape. Obtained data can be used for modifications of problematic elements on the part, reproduction, design optimization, analyses, inspection or in other downstream applications. Depending on your preferences a model can be created with high quality surfaces (high smoothness and curvature surfaces connection) or highly accurate models with deviations from the original measured part in tenths of millimetres. Professional RE software programmes Rhinoceros (Rhino Revers module) and Tebis. Both contain a variety of tools to meet the highest criteria for the quality of a digital model. Rhino is used mainly for design models, whereas Tebis is a professional CAD/CAM and RE software that allows for machining process and simulation, in addition to the RE and surface modelling.
Our capabilities include machining of parts made of wool and plastic materials. The CNC milling machine Charly Robot 2U is used for machining parts with higher accuracy, for example molds for vacuum forming of plastics, master models for casting in silicone molds, etc.
