LDM extruder - version 3 by piuLAB
by Thingiverse
Last crawled date: 3 years, 3 months ago
The 3Drag LDM extruder is an extruder for viscous fluids. Different materials can be extruded from a standard syringe. We continuously developed this extruder gaining experience from our researches with different materials. Check our website to know more about +LAB and our research.
What's new in the third version?
The syringe holder is stronger and can be used to easily mount syringe from 10ml to 60ml.
The extruder assembly is divided into three main parts. If one component broke you can easily switch is without disassembling all the extruder.
The completely redesigned drive unit is stronger and smoother. The M8 screw has been substituted with a T8 lead screw.
CAD files are available on GitHub
This is the third version which upgrade the second version
BOM
The extruder is specifically designed for 3Drag 3D printer. You will need a 3DRAG printer to modify.
