Today additive manufacturing is becoming more available on the global market because of the development of low cost 3D printers. In the market of low cost 3D printers, the most applied process of additive manufacturing is Fused Deposition Modeling – FDM. Specific market segment of low cost 3D printers is a market of 3D printers with large build volume especially in the direction of z axis (height). Because additive manufacturing has its advantages and its disadvantages regarding to subtractive manufacturing, interesting share of the market is hybrid manufacturing machines that have possibilities of exchange tools for manufacturing with additive and subtractive process. The market of hybrid manufacturing machines is still emerging. The concept and prototype of low cost 3D printer with a larger build volume in direction of z axis is elaborated within the thesis. Capability of tool exchange is elaborated within the concept design. With the extruder (that is made as a tool within the thesis), there is a possibility to mount another tools for manufacturing with subtractive methods. With a concept design and comparison of additive and subtractive manufacturing there is a possibility to note advantages and disadvantages of the machine if the subtractive tools would be mounted. Modular design of the machine has a great advantage because upgrades and improvements would be easily achieved.
