rigid.ink – The Most Reliable Black FLEXIBLE PLA Filament 1.75mm for 3D Printing *0.05mm+/- Tolerance* 3D Printer Filament 10m Sample

I'm using this very successfully on my Prusa Original i3 MK2S. Using the default settings for Prusa's own flexible filament in the Prusa Control slicer, I found that the filament underextruded and didn't stick to the bed properly. I have since experimented using Slic3r and these are the settings that work for me:nozzle temp 250ºCbed temp 70ºCextrusion multiplier 1.2extrusion speed 20mm/sThe filament sticks securely to the bed and prints consistently well. I have used it to make tyres for a robot project and with 10% infill, the tyres are nicely springy. This filament is more expensive than other brands but I have had zero problems loading and unloading filament, no clogged nozzles and no failed prints, so I think it is worth it.

I was looking for a well priced and high quality flexible material to use with my bowden style 3D printer; the Creality CR7. The printer I had before was a direct drive and I had always heard horror stories about bowden style machines not working with flexible materials and so rather than ordering a whole roll of the stuff I ordered this sample. I would argue that this review would extend to the whole roll in terms of the filament itself.I ordered both the sample of red and green for testing; I loaded a custom profile for flexible material that I had created for my Prusa and adapted it for the new machine. Most places recommend that you print slow so I started at an average of 30mm/s second and at this point have got it running perfectly at 40mm/s.The material itself is VERY high quality and comes in an awesome resealable package; the designs are really cool on the package and the name of the company (Rigid Ink) is VERY smart; it took me ages to figure it out :pCons?Well a small con was the fact that the sample was twisted in a few places which may be an issue if you start printing straight away, however I unravelled the filament and then wound it onto a spare spool which makes printing a lot better and a lot more risk-free. I wouldn't say this is the companies fault however, its really more of a thing to watch out for :)Also I would love for the delivery to be free, and the PLA to be a bit cheaper because then I could stop using other brands and be able to buy all my stuff at once and from the same place; overall though if I want some more exotic colours such as gold or silver PLA then I definately think that I will buy from here!That's pretty much about it really; oh wait no I didn't find a card in the package which told me how to print the material which I thought I read somewhere that there would be, but luckily I already have experience with this stuff so its all gooood ;)I will be buying from here again :)

I bought the 10m pack as a trial as I have been hearing mixed reviews about being able to print with flexible filament on my 3D printer (Flashforge Finder)I printed a Batarang from thingiverse for my son using normal PLA and within the first 2 minutes it broke, plus I had to sand the edges down as they were razor sharp and unsuitable for throwing at his mates.........well, some of them :)After a bit of research online I realised flexible PLA would be the way to go as PETG seems to warp on the Finder and ninjaflex seems to be a little too flexible going through the extruder and tends to clog apparently.... so I went for Rigid.ink.The product came within 2 days and packed well with the rigid.ink packaging being incredibly eye catching and just as functional as it keeps the filament inside safe from moisture and damage.I'm seriously impressed with the quality of the print with no warping or stringing and the instructions on the pack gave information on the print settings which I followed and had no issues whatsoever.I'll definitely be buying the larger spools and can use them whenever I need flexibility in a print.

I used this semi flex filament for the first time. I thought it was never going to print as it felt so flexible. The colour is a great true red.I printed it on a Wanhao i3 Plus. I printed at 0.2 layer height. 220 / 70. 15% infill.It printed perfectly apart from some overhangs, next time I will try supports, it just seems strange to have flexible supports.The finish was excellent a nice glossy red with minimal layer lines showing.I recommend this filament.

As I am new to 3D printing my ignorance bit me in the backside with this purchase - however that was of no fault to the product, it came packaged well and is of very high quality however as this is a flexible filament (akin to Ninjaflex) it requires some special care when extruding as you may end up like me and find it buckling in your extruder.Rather pleased with it but got more rigid filament, however this will do nicely when I have a better grasp and want to do a multi extruder setup for flexible joints and such.

This flexible material opens up a lot of new possibilities for shock absorbers, flexible joints, belts, gaskets and the like. The amount of flex can be controlled by varying the infill and wall thickness.When using the recommended temperatures and speeds (I use 15 to 20mm/s at 240°C), this prints almost as easily as regular PLA. It is essential to use a cooling fan which is enabled all the time, or your print will end up a congealed blob. Don't expect it to make perfect sharp corners though, that is nearly impossible with this kind of material. Do not try to print this directly on a BuildTak-like surface, or it risks becoming fused to it. Use an extra layer of painter's tape. It offers good adhesion with a bed temperature of 75°C.

so far only used a bit of one to make a band to fit a motorised part and printed lovely and has a nice bit of stretch on it so makes replacement belt and later going to try making tyres for a rc car

I bought this product in order to print toys for my grandson. I have an i3 direct drive and found no problem in printing with this filament. It flows perfectly and bonds as well as any other filiment I have used. The resultant print exceeded my expectations.

Always buy from rigid ink, reliable and great quality

it looks good so far.

I found it to be too soft to run thru a mendel type setup, not strong enough to be push thru and would coil in pinch roller area, but works well when put thru a 3d pen.

The rigid.ink flexible PLA comes out really well with minimal fuss. I use a Wanhao Duplicator i3 v1 with the mk10 all metal hotend and I had no issues with my first print, even...

Really good results from this, Once i managed to get the setting right.
