3D列印的流程如下
1. 繪製圖形並產出STL檔案
2. 將STL檔案經由切片軟體轉成3D列印機可讀取的G代碼
3. 3D列印機讀取G代碼,列印成形
由上面流程可知在3D列印前需要有G代碼
而G代碼是由STL檔案丟入切片軟體運算後所產生
因此3D列印前需要準備STL檔案
另外必須注意的是,繪圖軟體產出的STL檔案,若解析度不夠,列印出來的效果就不佳
下面兩個圖片,可以比較解析度差異對於列印結果的影響
而各種不同的繪圖軟體匯出STL檔案方法各有不同
以下對各種繪圖軟體分別介紹
3DS MAX
1.選單>導出> StereoLitho（* .STL）
2.物件名稱：名稱輸入要以STL的格式儲存。
3.二進制/ ASCII： 選擇STL輸出檔案是二進制還是ASCII（字符）數據。
4.選擇要匯出的物件。
