Rapid prototype is more and more popular in Industrial Design. Plastic prototype & Metal Prototype are called Rapid Prototype.And Metal prototype can be made with Stainless Steel, Aluminum, copper or other metals.
Today we are talking about stainless steel Rapid Prototype. Compared with Plastic parts, stainless Steel prototype is more difficult in CNC machining because of material characteristics and structure. Stainless steel is used where both the properties of steel and corrosion resistance are required. Material is very hard. When we machine stainless steel material, we need to use spindle power machine to process. As usual, Stainless steel prototype is not advised to be machined by separating into pieces because there will be a split line of welding which affect appearance.
It is important to find a Prototype factory with rich experience.
