一种轻质发泡型PLA 3D打印材料
产品简介
FusFun™ PLA-Aero Pro是一款在打印过程中进行发泡的PLA耗材。在打印前，发泡剂在耗材内处于未激发状态，在打印过程中通过调整打印温度可以自由控制发泡助剂发泡倍率，最大发泡倍率可达200%。

其他建议：
- TPU材料暴露在空气中容易吸收水分，建议您打开FusFlexTMTPU-Aero真空铝箔袋包装后立即将线材放入干燥盒内（湿度控制在15%以下）进行打印，不用的线材请放回原包装铝箔袋内密封保存。
TPU materials are prone to absorb moisture when exposed to air. It is recommended to place the FusFlex™ TPU-Aero filament into a dry box (humidity controlled below 15%) immediately after opening the vacuum aluminum foil packaging. Unused filament should be sealed back in the original aluminum foil packaging.
- 长时间暴露于空气中的TPU-Aero线材，请先将线材放入70-80°C烘箱内干燥4-6h后进行打印，避免材料潮湿使得挤出线条中存在气泡、孔洞，拉丝等问题。
For FusFlex™ TPU-Aero filament that has been exposed to air for a long time, it is recommended to dry the filament in an oven at 70-80°C for 4-6 hours before printing to avoid issues such as bubbles, holes, or stringing caused by moisture.
- 由于发泡类材料在热端融腔内受热会不断膨胀，空驶时会不可避免的出现漏料情况，即使调节回抽距离和回抽速度也无法改善，建议在切片软件中关闭回抽功能，一次仅打印单个模型或使用逐件打印功能，减少因长距离空驶和跳跃造成的拉丝和漏料缺陷。
Due to the continuous expansion of foaming materials in the hot end chamber, leakage is inevitable during travel movement. Even adjusting retraction distance and speed cannot improve this. It is recommended to disable retraction in the slicing software, print only one model at a time, or use the print-by-part function to reduce stringing and leakage caused by long-distance idle movements and jumps.
- 部分PEI涂层或PEI贴膜的打印底板可能会对TPU类材料粘接力过牢，难以取下打印件。建议使用无涂层的不锈钢板并涂抹少量PVP胶水后作为构建底板。
Some of PEI textured or PEI film build plates may exhibit excessive adhesion to TPU materials, making printed parts difficult to remove. It is recommended to use an uncoated steel plate with a small amount of PVP glue applied as the build surface.
