A multi-DOF rotary 3D printer:machine design,performance analysis and process planning of curved layer fused deposition modeling(CLFDM)
Most processes of additive manufacturing(AM)are conventional flat layer deposition with uniform layer thickness in a fixed build-up direction(Z axis)to acquire the geometrical shapes.However,there are plenty of drawbacks,not only the staircase effect and intractable support structure that may reduce geometrical accuracy,but also the weakness between lamination layers that can cause poor mechanical properties.In order to solve these problems,a rotary 3D printer possessing multi-DOF is investigated here,particularly related to curved layer fused deposition modeling(CLFDM)to realize materials accumulation along multiple directions.Meanwhile,the printer is equipped with two parallel collaborative nozzles to improve the efficiency.In addition,the technical challenges in developing such a multi-DOF rotary 3D printer are discussed including but not limited to the machine design and control system,motion analysis and simulation,workspace and printing process analysis,surface layering and tool path planning.A discussion of future development on the system is also presented.All those are going to provide important references for researchers and promote the development of parts with better geometry and higher performance.
