Our basic guidelines for 多射流融合 include important design considerations to help improve part manufacturability, 加强化妆品外观, 并减少总体生产时间. ​

  US 度规
最大一部分大小 11.1 in. x 14.9 in. x 14.9 in 尺寸:284mm × 380mm × 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,公差为+/- 0.012 in. (0.30毫米)+ +/- 0.002 in./in. (0.002mm/mm) for each additional inch can typically be achieved. 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. 皇冠游戏大厅app下载建议保持均匀的厚度0.125 in. (3.175mm),以确保稳定性.









MJF材料选择

PA 12黑

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 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矿物填充后.

主要好处

  • 经济的材料选择
  • 热偏转

We use HP Jet Fusion 3D 4210 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.


多喷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. 在每一层, powder is distributed on top of the bed and the process repeats until the part is complete.

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.
