Definition and application of process tools for rib structure de-sign in Large-scale additive manufacturing

Pavol Štefčák, Ivan Gajdoš, Łukasz Sobaszek, Yitbarek Firew Minale

This paper introduces an innovative approach to large-format robotic additive manufac-turing (LFRAM) by implementing a parametric point array patterning (PAP) method within Rhino Grasshopper. Unlike conventional slicing algorithms that convert 3D models into layers, the pro-posed solution generates toolpath sequences directly from parametric models. The method-ology leverages integrated Grasshopper components to create customizable ribbed structures with adjust-able dimensions and spacing, offering enhanced flexibility for large-scale applications. Experi-mental validation was performed using a FANUC M-20iB/25 industrial robot equipped with a pellet extruder, with PETG selected for manufacturing a structural component measuring 1500 × 100 × 60 mm. The research was conducted within the PROMATAI project during the rapid prototyping of the Adjusted Grooved Feed Section of the extruder (WP2).

The Value of Data in the Pre-AI Era | 前AI时代的数据价值

WU, JEFFI CHAO HUI

《前AI时代的数据价值》简介 本文作者巫朝晖(Jeffi Chao Hui Wu)基于跨越四十年的个人实证记录与多领域系统构建实践,系统性地提出了“前AI时代数据”这一核心学术概念,并将其严格界定为:2022年底生成式人工智能(Generative AI)以低成本、高仿真度大规模介入公共互联网内容生产之前,由真实人类大脑、真实的物理环境与真实的社会交互所产出的原始数字记录。作者认为,在当今海量AI生成文本、影像与逻辑推演泛滥的“数字噪音膨胀”时代,此类数据正从传统档案升格为兼具唯一性与不可复制性的稀缺基础资源,其价值遵循严格的“数据年龄”准则——即形成时…
