How to ensure dimensional accuracy of FDM 3D printed PEEK parts?
While FDM 3D printing, complications may occur when processing large-size elements, such as the two-piece 40 cm model shown in the photo above, which, in addition to restrictive dimensional parameters, required the clearance along the entire element to be maintained while maintaining high strength parameters.
Dimensional accuracy depends not only on the technology in which we produce a given 3D print but also on materials out of which we build our element. Polymer’s technical parameters define the mechanical features of the given printout. We can’t forget about the importance of additional parameters, such as printer calibration, the type of used filament, and finally, the ambient temperature conditions.
Regarding heat and chemical resistance, the PEEK (Polyether Ether Ketone) polymer, as one of […]
