Making models.Despite the fact that there are design studios where "virtual" is replacing "actual" in vehicle development, for those who are interested in sticking with 3D models that they can see, touch and feel (without some goggles goggles, n the protective eyewear worn by dental personnel and patients during dental procedures. goggles see periocular leukotrichia. and sensor-lad-ened gloves), there is a new line of extrudable pastes from Axson Group (Paris; www.axson.com). The SC167 epoxy-based paste is said to provide superior mechanical characteristics for full-sized models when applied over polystyrene polystyrene (pŏl'ēstī`rēn), widely used plastic; it is a polymer of styrene. Polystyrene is a colorless, transparent thermoplastic that softens slightly above 100°C; (212°F;) and becomes a viscous liquid at around 185°C; or polyurethane foam Noun 1. polyurethane foam - a foam made by adding water to polyurethane plastics polyfoam polyurethan, polyurethane - any of various polymers containing the urethane radical; a wide variety of synthetic forms are made and used as adhesives or plastics or pre-machined forms, such as no bond lines. One user of the material is ARTWARE DESIGN (Courbevoie, France), which used the paste to develop a full-scale model of the Citroen C4. In developing the model, 20 mm of paste was applied to a rough-milled polystyrene block. The paste was permitted to harden for 24 hours Adv. 1. for 24 hours - without stopping; "she worked around the clock" around the clock, round the clock , then machined with a five-axis machine to final dimensions. Although the 24 hours is a comparatively long time for the material to set versus other materials, the paste is said to have less shrinkage Shrinkage The amount by which inventory on hand is shorter than the amount of inventory recorded. Notes: The missing inventory could be due to theft, damage, or book keeping errors. and lower internal stresses. [ILLUSTRATION OMITTED] |
