Problems solved by technology

In addition, subsequent removal of space-occupied structures requires additional surgery and may present complications as newly regenerated tissue may be damaged, leading to patient safety If the difference between the volumes results in the fat not being well embedded in the structure, the injected fat may undergo necrosis or it may be reabsorbed

Embodiment Construction

[0071] exist figure 1 In, the core steps of the printing process of the 3D implant 16 are outlined. In a first step 11, a 3D model 10 of an implant 16 is designed using computer aided design (CAD) software. At this stage, the 3D model 10 is primarily used to design the external shape of the implant 16 as desired (eg, to size the implant for a particular patient). In a second step 12, the designed 3D model is divided into layers using infill software. The second step 12 can be seen as a transition from the theoretical continuous 3D model 10 to a hierarchical definition of the continuous 3D model. These individual layers are so far undefined with respect to their internal structure (ie, the potential fill pattern for 3D printing of the layer). In a third step 13, manufacturing inputs are generated based on the layered 3D model. At this stage, an appropriate hatch pattern is selected for each layer of the 3D model 10 . The manufacturing input comprises a set of machine instr...

Abstract

An implant (52) for insertion into a patient is provided. The implant includes a three-dimensionally printed structure of layers. Each layer comprises an infill pattern of the three-dimensionally printed structure, the infill pattern of each layer comprising a set of infill lines. The implant includes a plurality of hollow channels (21). The layers are arranged on top of one another such that theplurality of hollow channels are formed within the implant, wherein the walls of each channel are formed by sections of the infill lines of a plurality of layers of the printed structure of layers. Atleast one hollow channel (21) extends between a first outer surface of the implant and a second outer surface of the implant. The at least one hollow channel is oriented in a direction which is tilted with respect to a reference axis (37) perpendicular to the first outer surface of the implant.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from European Patent Application 18177214.6 filed with the European Patent Office on June 12, 2018, the entire contents of which including all tables, drawings and claims are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to the field of implants, in particular, to 3D (three-dimensional) printed implants with internal channels and their manufacture. Background technique [0004] Today, breast enhancement and breast regeneration surgery is one of the most commonly performed procedures for aesthetic reasons. Since aesthetic aspects play an important role in breast surgery, one of the biggest concerns of women undergoing surgery is the appearance of the final result. In fact, the aesthetic aspect is crucial to the psychological condition of the patient, especially for women who have undergone breast cancer and as a ...
