If you are creating models in CAD, think about taking it a step farther with Computer Aided Sculpting (CAS). With this technology the designer is actually touching and manipulating their digital clay model. The designer is getting a feedback sensation from the model surfaces during the sculpting creation. The model feedback resistance to the robotic arm is giving a touch sensation.
In this design process, a user combines the visual 3D object on the monitor with a contact feel of the model. This helps to communicate the design ideas in the virtual world before you “3D print” it with Rapid Prototyping SLA; SLS or another layer additive or machining process.

This unique 3D touch-enabled system is offered as FreeForm Modeling Plus from SensAble Technology.
