250 g. Red FlexiSMART 1.75 mm Flexible filament TPU for 3D Printer - Flexible filament for 3D printing - TPE filament, TPU filament, elastic filament Superb flexy filament, easy to print with. Colours are good, nice solid opaque colours. VERY strong prints, basically treat as a solid rubber model! Near impossible to seperate layers etc, will stretch and snap like regular dense rubber items if pulled hard enough.Really great for quadcopter parts that need to be strong and a felxy.Its not super soft / squishy like some, more like a flexible rubber - great for camera mounts, motor soft mounts etc.Extrudes easily and reliably.I have used their red and green versions of this, both perform the same.My settings:(Wanhao Duplicator i3, 0.4mm nozzle, Glass plate bed)Flexy mod - only needed a short length of PTFE tube to bridge the small (4mm) gap between the ext gear and cold end throat opening - also the fine toothed ext gear.Clean the glass with alcohol and wipe to remove any dust or finger print grease etc.220 deg nozzle60 deg bed0.2mm layersfirst layer 115% extrusion to get a good squished first layerslow first layer (15mm/s)print speed about 25mm/sfan on after first couple of layers.Retraction on (about 2.5mm at 40mm/s)Supports work very well in latest Cura, easy to pull off and come off clean.

A little expensive but I do love the results. Even using a Bowden system, Ender 3, it worked well after some fiddling. Turn off retraction and 30/40 mm/s and it printed like a dream. Almost invisible side layers, used a very low infill that was horizontal and it gives a great stiffness in that axis but it's study and squishy in the others.

Information is a little limited on this filament unless you can read spanish but essentially a TPE (thermoplastic elastomer) material.But to mention that I did have to add a small adaption to my Makerbot Replicator 2, by adding a small piece of thin walled plastic pipe to cover the hot end securing screw (in between the hob drive and the start of the hot end assembly) which allowed a piece of 2mm bowden tube to be inserted into it. I then trimmed the end of the bowden tube to match the profile of the hob drive diameter (as best as I could). This adaption was to improve the guiding of the filament into the hotend as like all flexible filaments they need encouragment to get pushed through small holes without buckling or wrapping around the hob gear!...I have to say that I was amazed to have this material printing on a Makerbot Replicator 2 (with added heatbed).In my setup using the heated bed (at 50 deg) gave me more confidence to use the filament but the manufacturer does state that this is not necessary and it can be printed on an unheated or untreated surface. Quality was excellent with just a few strings attached to the part after printing. Extruder temp was 220 deg and printing at 25-30 mm/sec. Layer height 0.2mm with a 0.8mm retraction. FlexiSMART has around a 80-90 shore rating from my estimation which can be a little hard for some items, but again this will need time and testing to discover the best combinations for different projects.The manufacturer does claim that this will work in most direct drive printers but as like anything in 3D printing you need to prove theclaims...I'm happy to say that with a small alteration I have now the capability of using flexible filament (I tried Ninjaflex without success) in the Replicator at last so I am very happy and can recommend FlexiSMART as a consequence.So I can highly recommend FlexiSMART

Easy to use on a prusa mk3. Very hard to remove from the bed so need plenty of glue. Nice and flexible but layers will split if bend too much.

I almost never leave product reviews, but this one deserves a short one...Straight off first print with no tweaking from my usual PLA settings and it was acceptable, minimal stringing and layers looks very good, This stuff is super flexible, much better than expected. (Temps were : ext 200 deg C, bed 60 deg C on glass bed with Elmers gluestick)After quick visit to their website I found that they had simplify3d settings already for download, these proved to be 99% spot on for my printer (also had settings for all their other filaments for simplify3d, cura and slic3r)Overall very happy with my purchase, if all their other filament is like this then i'll definitely be buying again.

I almost gave up trying to make this work with a bowden setup until as a last resort, I backed my extruder spring tension all the way to the minimum. Suddenly, I could print this reliably at 50mm/s with 3mm and 40mm/s retraction!! Once I figured this out, this has been an absolutely amazing filament and have gone through almost one full roll with nothing but joy.The flexibility really depends on flow rate, number of walls and infill. At 100% flow rate with 2 walls and 15% infill, the parts can pretty much be flattened and they spring back to shape, with the walls behaving almost like an uninflated balloon. However, if you crank up the flow to 120% and 100% infill, it's almost like a car tyre.Also worth noting, it will string A LOT if stored without silica gel on a sealed container.All in all, a versatile material I will always keep around from now on.
