Hi Yoter, thanks for your reply. I have looked into te TAZ printhead, and it seems quite bulky and heavy. Not that my own design is going to be a small featherlight thing but still... Also i saw on the lulzbot website that it's not advisable to print rigid filaments with the extruder that is design for the flexible stuff. I would like to keep the option of printing rigid filaments too. I have begun designing a printhead with the bondtech extruder and two hotends. This is going to weigh around 500 grams, so I'll have to calculate how much the guiding rods will bend under this weight. I'd like to keep the maximum vertical displacement as a result of bending under 20 micrometer. The original setup, with the 6 and 8 mm rods bends around 17 micrometer with the original printhead, so it looks like i'm also going to have to place some thicker rods. rods bends around 17 micrometer with the original printhead, so it looks like i'm also going to have to place some thicker rods.

I Like iRoberti's designs, but I think placing the feeder directly above the hotend is the best/only way to get repeatable quality in printing flexible parts. Also, as I am conducting my thesis project in a company environment, It would be a plus to be albe to make use of of the shelf parts (like the E3D hot-end and the bondtech feeder). The design process I am going through is mainly selecting the right components, and finding a way to make them work together. That's why I want to know if people have already used those parts (seperately or together) to print stuff like ninjaflex. To give an idea on the direction I am going; I am planning to design a bowden-direct hybrid dual extrusion printhead with one nozzle retractable. I'm hoping to be able to post some screenshots soon.

Hi All, I am currently trying to design a printhead dedicated for flexible filaments as part of my bachelor thesis project. I am wondering wich feeder and which hot-end is the best for flexible materials. I'm talking about <90 Shore A stuff like ninjaflex, filaflex etc. I'm currently thinking the bondtech QR and E3D V6 might do the trick. Is there anybody who's tried printing flexible filaments with those parts?
