多噴射融合的常見應用包括:
- 需要一致各向同性機械性能的零件
- 功能原型和實際使用零件
- 具有精細特徵的複雜和有機幾何形狀
多噴射融合設計準則
我們對於多噴射融合的基本準則包括重要的設計考慮因素,有助於提高零件的可製造性,改善外觀質感,並減少整體生產時間。
| 美國 | 公制 | |
| 最大零件尺寸 | 11.1 in. x 14.9 in. x 14.9 in | 284mm x 380mm x 380mm |
| 層厚 | 0.00315 in. | 80 microns |
| 最小特徵尺寸 | 0.020 in. | 0.5mm |
| 壁厚 | 0.020 in. | 0.5mm |
公差: 對於設計良好的零件, 通常可以達到+/- 0.012英吋(0.30mm)加上名義長度的0.1% 每增加一英吋。請注意,公差可能會根據零件幾何形狀而改變。
翹曲: 翹曲:較大的零件尺寸(>7英吋)和具有薄特徵的零件最容易翹曲。我們建議保持0.125英吋(3.175mm)的均勻厚度以確保穩定性。

多噴射融合技術如何運作?
多噴射融合技術使用噴墨陣列在尼龍粉末床上選擇性地塗佈融合和細節劑,然後通過加熱元件將其融合成實心層。每完成一層後,粉末會鋪在床層上方,重複此過程直到零件完成。
製造完成後,整個包含零件的粉末床會移至加工站,透過整合式真空系統移除大部分鬆散粉末。接著對零件進行噴珠處理,去除任何剩餘的殘留粉末,最終送至修飾部門進行黑色染色,以改善外觀。
