[Update 24.12.01: Applying pressure in two stages can effectively avoid defects caused by material shrinkage. This approach allows for more precise control of the overflow length at the top surface, reducing the time needed for post-process polishing. Initially, 8.8g of PLA was recommended; now, 8.5~8.6g of PLA is advised. After the molten plastic is placed into the mold, apply pressure for 15 seconds, let it sit for 1 minute, and then apply pressure again for another 15 seconds.]
This is a mold for making dice by recycling 3D printing waste (PLA).The mold, printed using PETG (PETG-CF is a preferred alternative), can recycle approximately 8.8g of PLA at a time.
[更新24.12.01:如果分两次施加压力,将有效的避免因材料的收缩产生的缺陷,可以更准确的控制顶面的溢出长度,减少后期打磨的时间。起初建议8.8克PLA,现在建议8.5~8.6克PLA。熔化的塑料放入模具后先施压15秒,静置1分钟,再施压15秒。]
这是一个回收3D打印废料(PLA)制作骰子的模具,使用PETG打印(使用PETG-CF打印模具是更好的选择)。它一次可以回收8.8g PLA。
需要的工具: 烤箱,3M防毒面罩,硅胶烤盘,G型夹(1个),M2 10mm螺丝(1个,作为脱模顶针),平起子,锤子。
制作流程: 1,把8.8克PLA,放入烤箱,210℃加热约8分钟。
2,把模具用G型夹锁紧。
3,把熔化的塑料放入模具,插入活塞,并用力按压或踩活塞(约15秒)。
4,冷却约5分钟后,打开模具,并用M2螺丝作为顶针脱模。
5,去除毛边,用砂纸打磨。
