Production of prototypes used to require hours, tools and experience. Paper design from drawings were followed with utmost care and pain by accomplished craftsmen. Large, bulky and sophisticated equipment is required in traditional techniques of creating models. With 3D printer, technology has addressed the shortcoming of consuming much time and the need for speedier prototyping.

It is a computer assisted manufacturing process called rapid prototyping technology. The creation of a three dimensional model is unlike the use of plastic formers or metal modelling techniques in the past. Replicas, reproductions and prototypes are created by layering of fabrication material through the technology.

Advanced prototype production benefits engineers, designers, technicians and hobbyists to create custom designed 3 dimension models during conceptual stages of design. Prototype corrections, enhancements and project completion are facilitated by having an actual model to see and manipulate.

The numerous advantages of computer assisted design pose its edge over the traditional prototyping techniques. These printers are of course, faster, easier, cost efficient, desirable and more affordable. A 3D printer has done away with the previous long and timely fabrication technologies. It allows comfort of own workshop and has eliminated use of expensive tools and skilled craftsmen.

A 3D printer possesses the distinct advantage of being reasonably sized, compact, flexible, safe, and ease of operation. Compared to traditional techniques, it does not involve dangerous technique, toxic chemicals nor any toxins in the process. Work after production is reduced to the minimal from the substantial amount, particularly in clean-up of models and work area. The advantages rest in the areas of speed, cost and simplicity.

Prototypes created through traditional techniques were built from solid blocks of material. The technique in inkjet printing made use of granular substances to combine the materials. The model was produced after cutting away excesses.

The computer assisted design software crafts a replica by using liquid polymers from injectors. The small amounts of material in layers extruded by the inkjet nozzle form a three dimensional model. These materials are cured with ultraviolet light. The replica is built from the ground up with no excess and would be indistinguishable from the original design. The specifications of length, width and height are met as the 3D printer software calculates layer upon layer of the material. This sophistication of rapid prototyping would enhance creative abilities.

Additional advantages will become available as technology brings about a new innovation in 3D printer.
