Problems solved by technology

At present, the core of various thickness-adaptive slicing technologies is how to characterize the geometric changes and complexity of the 3D model. Various characterization parameters have been proposed continuously, but there are no characterization parameters specifically for the structural characteristics of biological scaffolds.

Embodiment

[0049] Such as figure 1 As shown, the present invention is mainly divided into four parts, ① preprocessing, ② thickness adaptive processing (ESD and IAD), ③ direct slicing and ④ postprocessing. The ESD sub-step and the IAD sub-step of the two components of the thickness adaptive processing are two completely independent steps, and there is no overlap of operands and operands.

[0050] The thickness adaptive processing ② is directly independent of the direct slicing step. The direct slicing step can accept the data processed by the thickness adaptive processing step to perform the thickness adaptive direct slicing operation, or skip the thickness adaptive processing step and directly accept the preprocessing step. The processed data was subjected to a uniform thickness direct slicing operation. These four steps constitute a dialog-based application with human-computer interaction in its user interface. The inheritance relationship of this dialog class is "class Slicer_Dlg: pu...

Abstract

The invention discloses a self-adaptive direct slicing method for a preparing biological scaffold. The method is secondary development using VC++ and conducted on a SolidWorks2011 platform, and the core concept provided by the method and a special treatment mechanism adopted by aiming at the three-dimensional mold characteristics of the biological scaffold can be particularly achieved by relying on other software and hardware platforms. The self-adaptive direct slicing method for the preparing biological scaffold is mainly divided into four parts including pre-treatment, thickness self-adaptive treatment, direct slicing and post-treatment. Two constituent parts, namely an ESD substep and an IAD substep, of the thickness self-adaptive treatment are two completely independent steps and are not overlapped on operand and operational objects. Algorithm or operation which wastes system resources and spends a lot of time during the preparation process is effectively avoided, efficiency can be improved, and precision can be guaranteed.

Description

technical field [0001] The invention relates to the field of additive rapid prototyping, in particular to an adaptive direct slicing method for preparing biological scaffolds, aiming at the application of digital micromirror (DMD) projection light-curing rapid prototyping to prepare complex spatial porous unit structures and complex free-form surfaces 3D model-adaptive direct slicing method for outer contour bioscaffolds. Background technique [0002] As one of the three elements of tissue engineering, biological scaffolds play a very important role in the repair or regeneration of tissues and organs. The structural design and final preparation process of bioscaffolds are another important factor affecting their performance besides material factors. Reasonable bioscaffold design often requires a micro-scale porous structure with good connectivity and porosity, and its external profile often requires the same shape as the original organ or tissue structure, usually a complex...
