LDM extruder - version 3

thingiverse

The 3Drag LDM extruder is an extruder for viscous fluids. Different materials can be extruded from a standard [syringe](https://www.rays.it/en/divisions/health-care/needles-and-syringes/injlight-without-needle-luer-lock-cone/). We continuously developed this extruder gaining experience from our researches with different materials. Check our [website](https://www.piulab.it) 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](https://github.com/am-craft/3Drag_LDM_extruder) This is the third version which upgrade the [second version](https://www.thingiverse.com/thing:4635819) #BOM + The extruder is specifically designed for 3Drag 3D printer. You will need a 3DRAG printer to modify. ###Hardware >####Mount plate + 4x nut M5 >####Syringe holder: + 4x bolt M5x50 + 4x nut M4 >####Guide + 2x square nut M3 + 2x set screw M3x10 + 1x bolt M4x10 + 4x bolt M4x16 + 4x bolt M4x30 + 2x steel rod (or tube) 4x157 >####Gearbox + 4x bolt M4x30 + 8x nut M4 + 2x trust bearing 10x24x9 [amazon](https://www.amazon.it/gp/product/B07G7YQS48/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) + 1x T8 lead screw 8x200 [amazon](https://www.amazon.it/SIENOC-piombo-stampante-motore-passo-passo/dp/B07LDZY8RY/ref=pd_sbs_328_1/259-3516373-8726167?_encoding=UTF8&pd_rd_i=B077MZKFG8&pd_rd_r=6788f39d-3ce7-4854-95e7-6d349e81c3a8&pd_rd_w=OOMLZ&pd_rd_wg=MpGhu&pf_rd_p=b1489bf1-65f3-44a5-bb2c-32fc48932bba&pf_rd_r=2Z90J8C87KN3GQ8JBNBE&refRID=2Z90J8C87KN3GQ8JBNBE&th=1) + 4x flat-head bolt M3x12 + 4x set screw M4x8 + 1x Nema 17 stepper motor ###Tools + M4 tapper + 8mm drill bit + saw + screwdrivers + hex key *3Drag LDM extruder, designed @ +LAB by Andrea Mantelli*
