可列印三維存錢筒模型之建構方法

Abstract

現今要取得存錢筒的方法或者是透過購買、或者是透過現有物品DIY加工，都會被限制而無法忠實呈現使用者想要的設計。 本篇論文提出一套三維模型設計輔助工具，可以讓使用者根據自己的需求設計存錢筒的三維模型，並使透過三維印表機列印出來的三維存錢筒模型具有實際存錢的功能。首先我們提供了三個取得三維模型的步驟，並依序將三維模型挖空、加入存錢筒的基本功能，最後再將成品列印出來。過程中希望簡化所有使用者需要用到的操作，使使用者能夠輕鬆、無負擔的創造具個人獨特性的存錢筒。 此外，製作存錢筒過程中的存錢部分挖空，也就是體積優化，適當的挖空法可以節省三維列印所需消耗的塑料和時間。我們也提出了平均曲率挖空法和滾球挖空法兩種方法。

Nowadays, we can get a piggy-bank by buying from the store or making a handmade one. Both of methods cannot reflect users’ design completely. In this thesis, we propose a 3D model design assistant tool. Users can design the 3D model of piggy-bank, which is equipped with basic function, by their requirements. First, we provide three different processes to get 3D models. After reduce volume of 3D model, add place to put money in and take money out, the 3D model can be printed with 3D printer. We want to simplify all operation in the process so that users can make their unique piggy-bank unburdened and easy. In addition, reducing volume of piggy-bank, or volume optimization, is important for saving printing material and time. Therefore, we propose two methods for volume optimization by mean curvature and Minkowski Sum.
