RP-Rapid Prototyping development tendency and application

With the global market globalization, competition in manufacture industry field is very fierce. New product development becomes the most important between competitors. Meanwhile, manufacture industry should meet the rapid change demands of customer. What’s more, manufacture industry should have flexibility; it can do small production and even one pcs production while the cost won’t increase. Thus, the speed of new product development and manufacture technique flexibility becomes the key points. Under this circumstance, RP-Rapid Prototyping comes to birth.

RP-Rapid Prototyping technique is a kind of new molding technique which based on theory of dispersed/accumulated forming; it combines the new technique of computer, CNC, laser and new material.

The basic process of RP: using CAD software to make 3D curved surface or physical model of the product. Scatter the 3D model into a series ordered 2D piece in certain direction (generally Z direction). According to information of every piece, making the process, select tooling parameter and generate CNC code automatically. Forming machine will make a series pieces and connect them automatically, then get the 3D physical model. Thus it makes easy to make the product and reduce the cost.

RP function: make the model rapid and accuracy according to 3D model data, no need of other equipments. Drive CAD model, make the complex model rapidly. The main difference between RP and NC machine is RP has high flexibility. No matter CNC machine or machining center, they all aim at one kind product, for example, lathe machining center, milling machining center. For different part, it needs different fixture tool. They have high flexibility, it can produce decades and even some pieces parts, while the cost don’t increase, but they cannot use separately, they need to make the rough blank first. While, RP has highest flexibility, for any product which not exceeds the forming size, it can be made without any special tool. In terms of making model, RP has advantages over NC machining, it is rapid and high flexibility.

Nowadays, RP has used widely in aerospace, automotive, mechanical, electrical equipments, medical science, building, toy, art ware field. No doubt, no matter in marketing or forming equipment and process development, RP technique has very good future.
