    Will this work on the maker select V2?
    New User U on Aug 13, 2017
    Has anyone tried this on the Monoprice Maker Ultimate / Wanhao Duplicator 6? Will it work with the stock configuration?
    Sidney S on Jan 26, 2017
    BEST ANSWER: Thank you for your question. This filament can work in the Maker Ultimate. You would just want to make sure to take the necessary adjustments when printing with flexible filament for it can jam/clog much easier than harder plastic. You would want to print slower (30-40mm per second), adjust the retraction rate as you see fit, and make sure you have the temperature of the extruder and bed set correctly. If you require additional assistance, feel free to reach out to our knowledgeable Tech Team as Tech@monoprice.com.
    Is this TPE material considered to be the FLEX material listed in my owners manual for the Maker Select plus?
    New User U on May 5, 2017
    BEST ANSWER: Thank you for your question. Correct, TPE will be flexible filament.

    can I use this with the mini select printer?
    Gary Y on Apr 8, 2017
    BEST ANSWER: Thank you for your question. The Mini Select Printer will work best with PLA and ABS, though it would be able to heat to the required temperature of the flexible filament.

    Inconsistent diameter
    In my opinion the superior price is really only useful if you have an extruder that can handle filament that is far under 1.75mm. I'm not sure if they take returns on filament, but you may want to hold on to the box longer than I did and make sure it works with your extruder before tossing the box. Usually the biggest with flexible is having it buckle or loop around your gear wheel, but for me the biggest problem with this particular spool has been the small diameter so when it hits one of the smaller sections the filament ends up just sitting there with the gear spinning. If I had kept the box to ship it back in I would probably even try to do a return despite the better price than other flexibles - it's significantly harder to print with than flexibles with larger diameters.

    I have attached a Youtube video of a segment of the spool that I cut off, as you can see my calipers measured 1.51mm - with pressure that dips all the way down to 1.3mm which is simply too thin for any bearing based extruder. (spring tensioned might be able to use it still)

    PROS: Good price when compared to Ninjaflex.

    CONS: I would have the filament stop feeding, with my idler turning but the filament not moving. My extruder can handle fluctuations in diameter, but not quite to the degree of this filament. I pulled out my calipers and at some points it dipped all the way down to 1.5mm. With it being flexible filament if I then compressed it at all (and generally filament does get compressed into the gear in order to be driven through your extruder) it dipped even lower than that which my extruder just couldn't handle.

    Poor Results (so far...)
    So over the last few days I have played with multiple parameters using the flexible 1.75mm filament with my Monoprice Dual extrusion printer. I have to say this is the first real problem I've had with any filament or the printer since I bought it almost a year ago. The Monoprice printer is excellent and better than any other FDM printer I've ever used. I've used dozens of different filaments with this printer and all have worked very well. This filament is the first that has not worked though.

    If I had to guess, I think it is a problem with the material being too soft. I have ninjaflex which seems to be moderately stiffer. It pulls into the extruder fine compared to the Monoprice material. I have cleaned out the extruder head multiple times but still it fails to load properly most of the time. If I do get to load it draws very slowly, and once I'll start a print its as if nothing will even come out. I've tried multiple speeds, temperatures, etc with no luck. I'll keep trying to find any parameters that work, but until then I'd avoid this filament.

    PROS: Good price for 1Kg spool

    CONS: Won't get a consistent print. Won't load properly compared to ABS or PLA.

    Good product but had to print at much higher temp
    I printed this on the Maker Select Printer with a Flexion extruder upgrade and a glass bed with no treatment. I was only able to get good bed adhesion at 255 C extruder with 60 C on the bed (actually read 60C with IR thermometer). I printed a bike handle which looks and feels great! I had it bind up twice but it could have been due to a number of factors. The symptom was a knot of material that wouldn't fit into the hotend intake.

    3D printing is an adventure. and this is one of the more challenging filaments. I sliced my print with incrementing temperatures from 215 to 260 C in 5 degree increments until I got good adhesion. I found that the lower temperatures would be pulled off the bed at the next pass of the extruder nozzle and loop around the extruder. Eventually enough built up that the print failed.

    PROS: Good Material
    Great Price

    CONS: Suggested printing temps didn't work

    Complete failure to print
    My experience parallels that of Nate above. If there is a printer out there that is just the right configuration to work with this filament I would like to know which one it is. The filament is too soft to feed through the Bowden tube of my Rostock Max. It just bunches up in the extruder housing. It also failed to work at any temp on MonoPrice’s own Maker Select Mini printer. It fed a short amount and then completely clogged the extruder head, which will probably need to be disassembled now. I previously requested a refund but it was ignored. I cannot recommend this filament to anyone based on its complete failure to print.

    PROS: None

    CONS: Too soft/Binds and clogs easily
