Considering practical use, a solid and periodic cellular structure, which is called the lattice structure, should have a clear division of roles in orthopedic implants and be properly mixed in each customized implant (Fig. Implants must have both body strength and bone growth potential at the junction to the host bone. ( c) A postoperative plain radiograph of the applied pelvic implant. ( a) Designs and ( b) photographs revealed that the pelvic implant has both solid and lattice structures. Pelvic implant manufactured by metal 3D printing for a 35-year-old woman who received surgery for Ewing sarcoma of the left pelvis. Although the accuracy was low, precision was high for pore cells, so reproducibility was confirmed. The actual micrometer-scaled printed structures were significantly different to the design, but this error was not random. No strut breakage or gross deformation was observed in any 3D-printed specimens, and the pores were uniformly fabricated with < 10% standard deviation. The actual average pore sizes for 1.15, 1.5, and 2.0 mm outputs were 257.9, 406.2, and 633.6 μm, and volume porosity was 62, 70, and 80%, respectively. Pore size was calculated from unit size and strut thickness, and porosity was determined from the specimen’s weight. For each specimen, the actual unit size and strut thickness were measured 50 times. ![]() ![]() Beam compensation was applied, increasing it until the vector was lost. The cube-shaped specimen was printed with one side 15 mm long and a full lattice with a dode-thin structure of 1.15, 1.5, and 2.0 mm made using selective laser melting. Thus, we aimed to investigate whether targeted pores can be consistently obtained despite printing errors. However, designs and 3D-printed products can vary. Lattice structures for implants can be printed using metal three-dimensional (3D)-printing and used as a porous microstructures to enhance bone ingrowth as orthopedic implants.
