→ 什么是多喷射融合3D打印?
多射流融合 is an industrial 3D printing process that produces functional nylon prototypes and end-use 生产部分 in as fast as 1 day. 最终零件展示质量表面完成, 良好的特征分辨率, and more consistent mechanical properties when compared to processes like selective laser sintering.
多射流融合的常见应用有:
- parts requiring consistent isotropic mechanical properties
- 功能原型和最终使用部件
- 具有精细特征的复杂有机几何
多射流聚变设计指南
Our basic guidelines for 多射流融合 include important design considerations to help improve part manufacturability, 提升颜值, 并减少整体生产时间.
| US | 度规 | |
| 最大零件尺寸 | 11.1 in. x 14.9 in. x 14.9 in | 284mm x 380mm x 380mm |
| 层厚度 | 0.00315 in. | 80微米 |
| 最小特征尺寸 | 0.020 in. | 0.5mm |
| 壁厚 | 0.020 in. | 0.5mm |
公差: 对于设计良好的零件， 公差+/- 0.012 in. (0.30mm)加上0.标称长度的1% 通常每增加一英寸就可以实现. Note that tolerances may change depending on part geometry.
弯曲: Larger part sizes (>7 in.) and parts with thin features are the most susceptible to warp. 正规买球十大排行平台建议保持均匀的厚度0.125 in. (3.175mm)，确保稳定性.
MJF材料选项
PA 12黑色
pa12黑色是一种高拉伸强度尼龙. 最后的部分被染成黑色, and they exhibit quality surface finishes and slightly more isotropic mechanical properties when compared to SLS. When more detail is required, PA 12 can achieve smaller minimum feature resolution (0.与SLS材料(0.03 in). PA 12黑色 is the best material option for designs that incorporate living hinges.
主要好处
- 近各向同性力学性能
- 经济的材料选择
pa12 40%玻璃填充黑色
pa12 40%玻璃填充黑色 is a 40% glass-filled nylon. 最后的部分被染成黑色. The biggest advantage offered by this material is heat deflection at 347°F (measured at 66 psi), 排名2nd 最好在pa12矿物填充.
主要好处
- 经济的材料选择
- 热偏转

We use HP Jet Fusion 3D 4210 and 5210 machines that are capable of accelerated build speeds when compared to other powder-based additive manufacturing technology. The HP 3D printers produce commercial-grade parts with enhanced surface finishes and improved mechanical properties compared to other 3D printing technology.
为什么使用多射流融合?
See how 3D printing with 多射流融合 is ideal for functional prototypes and end-use, 生产部分.
多射流聚变是如何工作的?
多射流融合 uses an inkjet array to selectively apply fusing and detailing agents across a bed of nylon powder, which are then fused by heating elements into a solid layer. 每一层之后, powder is distributed on top of the bed and the process repeats until the part is complete.
当构建完成时, the entire powder bed with the encapsulated parts is moved to a processing station where a majority of the loose powder is removed by an integrated vacuum. Parts are then bead blasted to remove any of the remaining residual powder before ultimately reaching the finishing department where they are dyed black to improve cosmetic appearance.
