Towards Foundational AI Models for Additive Manufacturing: Language Models for G-Code Debugging, Manipulation, and Comprehension
3D printing or additive manufacturing is a revolutionary technology that
enables the creation of physical objects from digital models. However, the
quality and accuracy of 3D printing depend on the correctness and efficiency of
the G-code, a low-level numerical control programming language that instructs
3D printers how to move and extrude material. Debugging G-code is a challenging
task that requires a syntactic and semantic understanding of the G-code format
and the geometry of the part to be printed. In this paper, we present the first
extensive evaluation of six state-of-the-art foundational large language models
(LLMs) for comprehending and debugging G-code files for 3D printing. We design
effective prompts to enable pre-trained LLMs to understand and manipulate
G-code and test their performance on various aspects of G-code debugging and
manipulation, including detection and correction of common errors and the
ability to perform geometric transformations. We analyze their strengths and
weaknesses for understanding complete G-code files. We also discuss the
implications and limitations of using LLMs for G-code comprehension
A Deep Learning Framework for Design and Analysis of Surgical Bioprosthetic Heart Valves
Bioprosthetic heart valves (BHVs) are commonly used as heart valve replacements but they are prone to fatigue failure; estimating their remaining life directly from medical images is difficult. Analyzing the valve performance can provide better guidance for personalized valve design. However, such analyses are often computationally intensive. In this work, we introduce the concept of deep learning (DL) based finite element analysis (DLFEA) to learn the deformation biomechanics of bioprosthetic aortic valves directly from simulations. The proposed DL framework can eliminate the time-consuming biomechanics simulations, while predicting valve deformations with the same fidelity. We present statistical results that demonstrate the high performance of the DLFEA framework and the applicability of the framework to predict bioprosthetic aortic valve deformations. With further development, such a tool can provide fast decision support for designing surgical bioprosthetic aortic valves. Ultimately, this framework could be extended to other BHVs and improve patient care
