SLS prototyping is only one of production ways in rapid prototype field. When customer wanted the prototype to be made from Nylon. Most of time, it's a good choice to do it by CNC machining. But because of nylon material can not be splited and glued, that means it has to be made as a whole piece. For some complex parts, it will be impossible to machine. Thus it has to be made by SLS rapid prototyping technology to fix the problem. Actually SLS prototype is not main trend since nylon is not often used engineering material in industry. But [...]
