With development of new technologies the production is growing as well. Considering this the emphasis is placed on effectiveness and speed with which it is possible to test and make a new product. A 3D printer is an ideal utility in the area of prototyping. It is applicable for fast production of covers, ergonomic component and also small function elements. It is often necessary to design simple electronics in various areas of industry and at the same time to be able to test it. In this article we elaborated a possibility of replacement of a working head of a 3D printer with parallel kinematic in exchange for a head for subtle engraving of predominantly printed circuit boards. The main body of the 3D printer’s effector is equipped with exchangeable system. It is enough to disconnect control cables, undo arrestment and replace working desk. Then it is necessary to connect controlling electronic. Moreover it is essential to improve working table. The working desk with clamping system is placed on the heated bed printer.
