#9 EXTRUDER ASSEMBLY - BUILDING THE BIG 3D PRINTER

At last! the extruder assembly! I opted for a Bowden configuration, not sure if it is the best and I never used one but this is learning opportunity as best as any other. Per popular request: The J-head set: http://www.ebay.com/itm/3D-Printer-J-head-Hotend-With-Fan-Wade-Extruder-0-4mm-Nozzle-Volcano-pack-/262328117328?hash=item3d13f96850:g:XMkAAOSwP~tW4Ppw this is the international ebay.com link, I bought it in Ebay Spain. The metal extruder assembly was bought here: http://amzn.eu/4jAiL2V this is the Amazon Spain link I could not find it in Amazon.com Sorry!. A plastic version of the extruder assembly thanks to Doug Walmsley: https://www.amazon.com/BIQU-Injection-Extruder-Compatible-Filament/dp/B01G1K6FGK/ref=sr_1_fkmr1_1?s=industrial&ie=UTF8&qid=1487098688&sr=1-1-fkmr1&keywords=Plastic+Injection+Bowden+Extruder+for+Printer+Reprap+3D Enjoy!!

1. Will you post the STL files of all printed components? ;)
2. Clear instructions, good tone, no noises. That was a crystal clear tutorial, thanks.
   And you see, Ivan, your accent is really nice
3. an awesome proyect dude, how much money you will spend on this?
4. great video
   nice build
5. how many cost all The stuff for this 3d printer?
6. foi a melhor extrusora que vi até agora , ops kkkkk. Muito bom.
7. +Ivan Miranda So you are going to release the details on how to build it? I am going to try and build a huge ass printer at some point but I need to fix my hictop prusa i3 first. Also, you should have dual extrusion so you can use a dis-solvable material to dissolve the supports and print a more accurate object. I have no idea how it works with the software stuff though.
8. I located another option, Plastic version which is a bit cheaper than the all metal version. https://www.amazon.com/BIQU-Injection-Extruder-Compatible-Filament/dp/B01G1K6FGK/ref=sr_1_fkmr1_1?s=industrial&ie=UTF8&qid=1487098688&sr=1-1-fkmr1&keywords=Plastic+Injection+Bowden+Extruder+for+Printer+Reprap+3D
9. Ivan - great work. I can't wait the end of the series so we all can start building our own versions of this printer :) Waiting to see the STL files.
10. 1. I've been looking for a build/review of that extruder so thanks!
    2. Good tip with alligning the extruder gear with an allen wrench.
    3. Why go with bowden over direct drive? Do you ever plan on using flexible filaments?
11. Is the NEMA 17's sufficient enough? Didn't You consider going with NEMA 23?
    Cheers from Poland. keep it up mate!
12. here's a link to the Extruder from Amazon in the USA: https://www.amazon.com/BIQU-Extruder-Feeder-Filament-Printer/dp/B01HGGYWB8/ref=pd_sbs_328_1?_encoding=UTF8&pd_rd_i=B01HGGYWB8&pd_rd_r=4CSCXVXG2AVCWPGQNFD0&pd_rd_w=JLAhB&pd_rd_wg=LFamh&psc=1&refRID=4CSCXVXG2AVCWPGQNFD0
13. love your accent, you speak as funny as recio in lqsa
14. I've found were I bought the two parts!!! The J-head set: http://www.ebay.com/itm/3D-Printer-J-head-Hotend-With-Fan-Wade-Extruder-0-4mm-Nozzle-Volcano-pack-/262328117328?hash=item3d13f96850:g:XMkAAOSwP~tW4Ppw this is the international ebay.com link, I bought it in Ebay Spain. The metal extruder assembly was bought here: http://amzn.eu/4jAiL2V this is the Amazon Spain link I could not find it in Amazon.com Sorry!
15. I think this is the extruder assembly: https://www.aliexpress.com/store/product/3D-Printer-All-Metal-Bulldog-extruder-Aluminum-Alloy-Parts-for-Both-1-75-3-0mm-E3D/1051583_32494548099.html
16. Great video as always. I know several people have commented on the hot end assembly. FYI, e3d online has a great tutorial on hot end assembly. Also, it helps to put heat sink compound on the threads of the steel tube where it threads into the aluminum heat sink (the cold end). That allows for better transfer of heat out of the tube and into the heat sink, so the fan can blow it away. Do not put the compound in the heater block however. That will transfer more heat toward the cold end. Keep up the great work.
17. Great video. I wish youd look up on your emails where you got that extruder from - I can only find ones like that for over $100
18. Most clear videos I've never watch. Thanks a lot. I'm waiting about stl files to start to make one . Incredible tutorials, really !!!
19. Great stuff! I am sure you will need a better jhead holder. my plastic ones last me about 15 hours of print each, so each time I make 3 spares!! hehehe
20. Are your parts printed in ABS ? or PLA ? if PLA then you might want to reprint the hotend heatsink holder in ABS.
