When we draw a picture of an object on paper, it has two dimensions, one in X axis and second in Y axis. In this picture you do not get the details about the depth ie Z axis. We can also draw this picture with a tilt and one can get the idea of the depth also. Still you will not be able to hold this object in your hand and see all the details in 360 degrees, in all the three axis viz X , Y and Z. This limitation is overcome by 3 Dimensional printing, and you can hold the object in your hand.
For printing a 3 dimensional object - you need two items;
1) CAD File, in which a design is made in a software language of STL or SLC format. CAD means Computer Aided Design
2) CAM machine to understand the above said language and build an object layer by layer. CAM means Computer Aided Manufacturing
This CAD CAM technology was introduced to Jewellers in late 1990 and first machine was installed in SEEPZ - Mumbai. As usual in initial stages, there was resistance to acknowledge and accept a new technology, but within next five years, it was firmly in place and now it is not possible for Jewellers, to live without CAD & CAM services, to manufacture jewellery profitably.
Jewelers are using this technology to make accurate Master Models and then use this Masters to make multiple copies and execute their order. With this method jewelers can maintain the weight of precious metal accurately, and avoid rejections from overseas clients. In last 15 years many CAD software are available in market to design a complicated jewellery and similarly many CAM machines are introduced which are giving out puts in wax and Photo Polymer Resin. These resins are castable just like wax OR can be used for making Hot Rubber Molds. Now these CAM machines are more accurate, faster and economical to acquire. Today in India there are around 250 jewelers are using CAM machines in house and another 30 service bureaus, providing CAD and CAM services in India. These service bureaus are the main engine to make this CAD CAM technology available to even a small time jewelers, at a very reasonable charges.
Sarto Electro Equipments Pvt. Ltd. is Distributor of M/s. EnvisionTEC GmbH, which is leading 3 D Resin Printing machine manufacturer from Germany.
