As technology in product development and manufacturing continuously advances, a lot of businesses and individuals are prototyping new products using 3D printing.
3D printing is a kind of technology known as additive manufacturing where 3D objects are made using a 3D printer. These printers are less expensive, more user friendly and can be faster than other kind of prototyping technologies. 3D printers are currently more affordable for small and medium scale business where rapid prototyping are usually brought to office.
In 3D printing, it is an entirely different process from your CNC Rapid Prototyping. Rather than being carved out of the real material, layers are “printed” out to form any 3D object from a file that is already keyed into the computer. The challenge is that the resin is very expensive. Because 3D printers can use resin at the moment only, prototyping using this technique would not let you to use or even test different materials. Inkjet printing is one kind of 3D printing that prints prototypes in a complete colour and also considered as the fastest method in printing. This type of printing uses powder to make a shape.
