Problems solved by technology

Its shortcoming is that the real-time monitoring system equipment is not only complex in structure and expensive, but also can only observe and analyze the deformation of additive manufacturing in one structure and one placement position at a time, and cannot efficiently evaluate the molding performance of additive manufacturing
Its shortcoming is that this method does not investigate the great influence of the position and shape of the test piece on the forming performance of additive manufacturing; Alloy and other hard tissue additive manufacturing

Abstract

The invention provides a high-throughput evaluation method for hard tissue additional material manufacturing forming properties. The high-throughput evaluation method includes extracting structural characteristics of the appearance and the morphology of hard tissues of human bodies and designing I, L, T and F-shaped typical components according to the structural characteristics; placing the corresponding typical components in a row to form different angles between the typical components and additional material manufacturing substrates and placing the I, L, T and F-shaped typical components infour rows according to categories; preparing specimens of the typical components selectively from titanium alloy powder by the aid of metal additional material manufacturing methods; acquiring three-dimensional entity models and spatial location information of the prepared specimens of the typical components, matching the three-dimensional entity models and the spatial location information with pre-preparation initial information, and acquiring all size deformation and microscopic tissue conditions of components of the typical components in different shapes at different placing angles at one step so as to carry out high-throughput evaluation on personalized hard tissue additional material manufacturing properties.

Description

Technical field [0001] The invention relates to the field of metal additive manufacturing, in particular to a method for high-throughput evaluation of hard tissue additive manufacturing forming performance. Background technique [0002] With the accelerated pace of human aging, the increase of young and middle-aged traumas, and the increase of patients with difficult diseases, there are more and more hard tissue injuries such as teeth, bones and joints. It is urgent to implant external materials to replace and repair damaged human hard tissues. Titanium and titanium alloys have good biomechanical properties and biocompatibility. In recent years, titanium and titanium alloy products have been widely used clinically as important medical implants. Due to the huge differences in individual bone structure, as well as the different lesion locations, sizes and shapes, it is difficult to prepare them through traditional mass production methods. Additive manufacturing of customized implan...
