3D printing demonstrates your strengths where conventional manufacturing has reached its limits. These manufacturing processes are often used in prototype construction, for components with a high degree of customization, and with complicated geometries. Our linear axes fulfil the requirements of 3D printing machines in terms of precision, dynamism, and operational reliability. Outdo the competition and turn your ideas into reality.


Additive manufacturing is continuing to make headway – and has become a genuine alternative to traditional manufacturing methods. 3D printing with plastic, metal or ceramic powders opens up new possibilities in product design, and clears the way for manufacturing components efficiently in small quantities. Linear axis systems are an essential feature in 3D printers. For example, they position the laser head in the portal group and feed in material layer by layer. Here, Bahr Modultechnik’s linear axes are used in a challenging environment that calls for a high level of positioning and repeat accuracy. Furthermore, the linear systems must achieve a high level of dynamism – and that in non-stop, 24/7 operation. Service life therefore really counts in additive manufacturing, as do operational reliability and drive performance.


Above all, it is linear axes with spindle drive and nubbed belts, that, with their precision and excellent rolling characteristics, determine quality in 3D printing. Additive manufacturing is used when the limits of conventional processes have been reached. The method is used to produce delicate components from various material powders with layer thicknesses ranging from 0.015 to 0.1 millimeter. Because of these new possibilities, more and more business divisions are employing this technology and discovering the benefits of the new production process. With that in mind, the printer and all peripheral equipment must be as compact as possible. This leads in the realization to custom-designed linear axes that are easy to integrate and that waste no space.

Bahr Modultechnik therefore always builds its linear axes to customer specifications from a modular construction kit. Everything in it is standardized for industrial application – but is freely configurable in the required length and a whole host of other customization options.
