RESIONE F69 Flexible 3D Printer Resin 1Kg – 405nm UV-Curing Silicone Rubber-Like Photopolymer for DLP, LCD & MSLA Printers, Ideal for High-Resolution 3D Printing

I bought a used camera a while back, and one of the two doors on the side was missing. I figured I'd but a replacement from the manufacturer, but they wanted $180 to install it, and refused to sell me just the part, hence I decided to make my own. The door has to be flexible, it has to press fit to keep out dust, dirt and moisture, and it has to to be tethered. The outside has a leatherette finish, and the inside has a protruding square seal. I originally designed the door in two pieces - a hard plastic outer piece, with a rubber sealing ring/tether. Then I found the F69. The properties of F69 were such that it was rigid enough for the outside yet flexible enough for the inside, which allowed me to print the whole assembly as one piece. Anyway, the door on the left is an original, and the one on the right is printed. You'd be hard pressed to tell them apart. In terms of ease of use, I had absolutely no issues printing with it. I did use heavier supports than normal - one article I saw suggested that. I also downloaded Resione's print settings for my printer. It worked flawlessly. There is only one downside with this resin -- the uncured resin has a very strong fumes. Next time I print with this I will definitely be relocating my printer.

I bought this to make some rubber mounts that had perished for a very old Shure 55SW and it worked perfectly. The only issue is that the smell was unbearable. I have my printer in my office on the second floor of my house and had to move it outside at night to print with this material. The whole house smelled like it, even though it was upstairs with 2 fans cycling the air in and out. It's not super soft and rubbery, it's firm and rubbery. It does take almost twice as long to print compared to plastic style resins as it needs more time per layer exposure. Hope that helps any potential buyer.

This resin can produce good results if you use the right settings, but the right settings aren't obvious.First, it is very opaque, so the plate has to be extremely level for the first few layers to attach properly.Second, it is *extremely* thick. This means that if you are printing any flat surface more than a few cm on each side, the resin won't be able to flow in and out quickly enough. This causes problems both on lift and return of the plate.On lift, it generates a suction force that can cause the print to detach from the plate, from supports or even from itself. The solution to this is to lower the raise speed to *extremely* low. I'm using 10mm/sec for the first four mm, 70mm/sec for the rest of the lift.A similar problem happens when the plate is going down: any relatively large surface will need to evacuate the resin as it goes down, and that won't be possible if the plate is moving too fast. As a result, at best the layers will be thicker than they should, and at worst they will peel off since they re too thick for the light to reach the already printed parts though the dark, opaque resin. For large flat surfaces I was getting at 0.05mm setting layers that were four times as thick! There I also use 10mm/second on the downward move for the last 4 mm, 50mm/second for the rest, plus I wait one extra second at the end of the move before lighting the LCD up.As for other settings, if I print at 0.05mm layers, they come out fine but for large surfaces they come out a bit thicker than desired even at those speeds, and at 0.1mm the thickness is as expected but I have to use an exposure time of 8 seconds for each layer, and 50 seconds for the base.So for large flat surfaces that require such values the printing process can be SLOOOW. Printing a patterned slate 2mm thick took 30 minutes! For smaller surfaces and shells I was able to do with faster (but still low) move speeds, but it's still much slower than printing with normal resins.As for the resulting objects, they are fantastic. I was able to print rubbery patterned surfaces that can be wrapped around contoured objects, model vehicle tires and other flexible items, with great accuracy and detail.Just be prepared to waste your first $57 on trials until you figure out the right settings. I am happy with the product, but I am dinging one star because the company should provide detailed guidance on the right settings for different scenarios given how out of the ordinary this resin parameters are.

this one was surprisingly good.It is thick like motor oil and needs a lot of IPA to be cleaned but once you have the right setting it will print really good.The material is very flexible and can be mixed with similar resins in case you want to lower the cost a bit (because it's quite expensive)

I needed a softer, semi-flexible resin to print some shark teeth for a project and wanted to make sure that nobody cut or poked themselves on the teeth. This resin worked great for what I needed. The teeth came out with a semi-flexible tip and when hollowed, is even more flexible. The profile for the Phrozen Sonic Mighty 8K that was provided on the support page worked wonderfully. I was getting successful prints on day 1!Just a note: I did have to make my support tips a little larger in diameter compared to my normal model resin.

I like that it UV cures... Sort of. It has a longer than normal cure time and stays sticky even after I leave it in for the time it says. I guess that's the latex rubber in it? Idk. But it's not as flexible or silicone-like as I imagined it to be (kind of like the advertised image?) It's not at all like that!! A little flexibile maybe and then tear, or it will be rock solid with enough softness to dent with fingernail. I definitely wouldn't do shoes with it though I think it would be uncomfortable unless you printed orthaprdic arch supports (but maybe also my cure times are off based on the power of my laser/printer or wavelength/nm difference? My opinion is based on that !! So.. We'll have to see what other people have to say.So just a meh 😑for me

I've used this resin for all kinds of builds from the small to larger models with excellent results. I recommend this to anyone who wants to have a dependable resin for their 3D printing projects.
