3D Systems Corporation has launched a fast, high-definition modelling system for desktop use in the office environment. The InVision XT 3-D system builds three-dimensional plastic models and prototypes quickly and efficiently, and provides high-definition, functional and durable models that are able to withstand rigorous handling and testing. It produces models in a variety of materials and colours (white, blue or dark grey), and melt-away supports enable hands-free post processing.
