Overview of design guidelines for the different constituent parts derived from experiments
| Constituent part | Design guidelines |
|---|---|
| Integration of elements into polymer matrix | Recess diameter is 0.4 mm wider tHan tde element |
| Undercut in design to conceal interfering z-seam | |
| Recess depth is one layer height smaller than the element height | |
| Lands for fixating an element should be narrow to avoid warping effects. Suitable for 1/2” elements are 1.5 mm and 2.5 mm for 1” elements | |
| To ensure stable adhesion, printing of the lands should begin on the surrounding polymer instead of the inserted element | |
| The imprinting of elements requires a flat surface, or suitable adapters should be used | |
| Printed thread | Thread is orientated perpendicular to the printing direction |
| Including a 45° x 0.5 mm chamfer at the beginning of the thread enhances the insertion of the screw | |
| Larger nozzle diameter requires for larger core hole diameter | |
| Suitable core hole diameters for different thread dimensions are given in Tables 3 and 4 | |
| Printed ball joint | Recommended gap between ball and socket is 250 µm to prevent them from sticking together |
| Wider gaps increase the ball play in the socket |
