WireMolding: 3D Modeling Approach Involving Molding with Wire
WireMoldingは、実世界で2次元的に造形を行った針金の形から3Dモデルデータとして扱える図面を自動で生成することによって複雑な3Dモデリングを支援する、実用に特化した3Dプリントの手法である。3Dプリンタの普及に伴い、個人の生活に根ざした3Dプリンタの使用シーンが想定されるようになってきた。しかし、身の回りの家具や道具に合わせた造形物を制作する場合、ものの形や大きさに合うように3Dモデルを設計しなければならず、モデリングの知識や技術を持たない初心者にとっては難度が高い。本手法に基づいて実装したシステムは、実世界で針金を押し当てて対象物の一部を型取ったり、自由に曲げて任意の形状を形作ったりして針金の型を造形し、その型を撮影して得た2次元の写真から実寸大の図面を生成する。3Dモデリングソフトで図面を読み込むことにより、高さの指定を行う操作のみで物の形にぴったり合う立体を造形することができ、特に難しい曲面の設計も手軽に実現可能で、誰でも簡単に３Dプリントによる道具の自作が可能となる。
WireMolding is a 3D modeling approach for practical personal 3D printing with which sketches can be created to construct a 3D model from the bi-dimensional shape of a physical wire mold. Due to the popularization of personal 3D printing, it is assumed that 3D printers are used at the scenes that came out of by demand from the general public. However, when we make practical tools for personal belongings or furniture by ourselves with a 3D printer, it is difficult for beginners without technical knowledge because of being necessary to design such tools to fit in with objects. The system we implemented based on this approach creates full-scale sketches from photos of molds made by bending wire into arbitrary shapes or molding parts of physical objects by pressing wire firmly against them. By importing such sketches into the modeling software, you can construct 3D models whose shapes are same as the molds and fit in with physical objects only by designating the heights of models. Moreover, this approach makes it easy to design curved surface of 3D models, which is especially difficult to construct. Anyone can make 3D models for 3D printing more easily with this approach.
