...es the functional tests are designed to verify and where the limits of the different prototype materials lie. If the above example had simply involved assembly tests for the intake manifold, for example, then a standard SL material (such as Somos Watershed or Somos White, offering a good surface finish and a high accuracy) would have been sufficient. In the case outlined, however, the requirement was not only for a dense, smooth surface from which no particles could become detached but also for ...

...ch has remained an unambiguous advantage of the laser sintering technology up to now. In the last two years, the variety of functional materials has been extended by the highly transparent materials Somos 10120 (waterclear) and Somos 11120 (watershed) and for the time being completed with Somos 14120 (white), a material with properties similar to ABS/PBT (Fig. 4). At the same time, the first filled stereolithography material, Prototool 20L, was developed in co-operation between DSM Somos and Al...

...ith sufficient dimensional stability. In his search for a solution, Jantet hit on the firm Materialise and its Mammoth unit, which was able to manufacture prototypes up to a length of two metres. The process uses Somos 9120, which simulates PP, and WaterShed 11120, which simulates ABS. Materialise decided to work with these synthetic resins (manufacturer: DSM Somos), because they produce precisely moulded parts that simulate the performance characteristics of engineering plastics very accurately...

...oncept vehicle. According to Protostyle, the capability to manufacture large models already exists. The size of the models is limited alone by the price. All SL parts of the concept model were made from a liquid photopolymer (grade: DSM Somos WaterShed 11120), which reproduces many characteristics of conventional engineering plastics, such as ABS and PBT. The solid, hard and water-resistant parts can also be subjected to functionality tests. This material is one of the most widespread SL synthet...

...d in each pixel marked as a cell cavity. This distance map is then smoothed and inverted. This yields an image in which the center points of the cells can be seen as local minima in the image. They serve as starting points for what is known as the watershed transformation. This marks correlated regions around these centers of the cells. The local and global features of the foam can now be calculated. Calculation of Structural Features The approaches used up to now for determining the structura...
