Comparative Analysis of the Stress–Strain State of a Lightweight 3D-Printed Shoulder Implant

The use of 3D printing in orthopedics has several advantages, one of which is a reduction of the implant weight due to the use of honeycomb structures. In this work, a technique for making a 3D-printed shoulder implant lighter without compromising its rigidity and strength is suggested. Comparative analysis of the stress–strain state of a shoulder implant has been carried out for two modifications of the implant: solid and honeycomb (lightweight). The first (solid single-piece) implant has been manufactured using conventional technologies; the second (lightweight honeycomb), by 3D printing. The honeycomb implant has been shown to exhibit the same strength as its solid counterpart, which makes it safe for orthopedic use.
