假設 我們已經學會更多3D列印的技術後 接下來會遇到的問題是⋯
• 我希望能印出有品質的作品 • 我希望印出的東⻄西有某些物理特性 • 我希望沒事能⾃自⼰己印⼀一點有⽤用的東⻄西

We can do this with materials, change the plastic we’re using and make a better plans.

They’ve already 3D-printed our favorite characters.

所以,結論是⋯你想得到的,幾乎都可以印得出來 前提是,你有財⼒力能負擔這些機器與材料(無誤)
所以接下來談談不同的材料與他們對應的列印技術

事實上⋯ 剛剛看過這麼多種技術
• 只是基本知識 • 必須根據⽤用途決定材料再決定搭配的技術 • 所以現在要來談有關材料的基本知識

但是,資料還是太多⾃自⼰己看過幾天資料發現 真的很難⽤用幾個⼩小時的時間讓各位變成3D Printing專家 只能給各位最基礎的知識建設
拋磚引⽟玉,各位如果有興趣深⼊入鑽研,記得回饋社會
