60ml Syringe Extruder for Liquid Deposition Modeling - LDM by piuLAB

Last crawled date: 3 years ago

Updated version of our experimental syringe extruder, it is designed for a 60ml syringe which is the perfect dimension for our printing need. The syringe model is a luer lock type, which means you can use a lot of different nozzles from the luer lock system.
The extruder is designed for a 3Drag printer (K8200), but you can easily adapt it to other system by designing a customized mount for your machine. 3Drag is a moving bed machine, so the extruder is still during the print without any issue of moving weight. If you use this on other printer models remember to slow down all head movements like print speed, travel speed etc.
The gear reduction ratio is 5:1, which is enough for printing in clay, but not enough for more viscous materials. This ratio has been decided for dimensional constraints of 3Drag printer, but for other machines a 6:1 or 7:1 ratio it is recommended.
-For the main body we had to design a very big part, around 30cm in lenght. In the next future the main part splitted in 2 smaller parts will be provided in order to be printable with all most common FDM machines.
