IC3D Grey 3mm ABS 3D Printer Filament - 2.1lb Spool - Dimensional Accuracy +/- 0.05mm - Professional Grade 3D Printing Filament - MADE IN USA

I have printed with various materials and printers over the last several years. I purchased this filament for use with my Ultimaker 2. I find this filament to be the best I have tried to date, on both small (1/2" or smaller) and large (8" or greater) prints. Prints using a small layer height (.06mm) come out with exceptional detail, and a great finish. Draft prints done with a large layer height (.25mm), and at high speed (150mm/s), also come out great with good bonding between the layers.At first, when printing with ABS on the Ultimaker, I was using the Ultimaker filament (2.85mm) and was having various intermittent issues. PLA worked okay, but the material properties of ABS was more suited to the mechanical parts I was designing. I decided to try the IC3D filament during my last refill, and have not had a single problem since. Each part prints well between 210 and 230 degrees, with or without fan usage. Adhesion is great on the Ultimaker heated glass platform using nothing more than a Staples glue stick. While I was a little nervous about using the 3mm filament in a printer that specifies 2.85mm, but it works great.I highly recommend this filament to anyone who needs to print with ABS.

To set the stage, I just purchased a Lulzbot Mini 3D printer (my first). I'm no newbie to 3D modeling, but 3D printing is new for me. I've been researching it for a week and I finally dove in head first. So, I purchased several different vendor's filaments to kind of "test the gamut". I'll give my review of the ones I've used so far, so others don't have to learn the hard way:After having printed half a spindle on both IC3D and Verbatim, I found the following:IC3D ABS Black 3mm filament prints very consistently. No change in print quality and no bubbles. I have printed several 4x2x2" brackets I specially modeled to mount a 42" smart TV to a specific 60" stand. I even took a hammer to the printed bracket and it wouldn't give (and it has a honeycomb pattern inside, so it isn't even solid)! I have to mention that the filament tries to fall of the spool and wrap around the spindle holder, but I think this would more likely be a Lulzbot Mini issue, rather than IC3D. I will probably print an add on to their spindle holder. I also printed a part that had broken on my RC car, which is holding up better than the original part (and oh yes, I took a hammer to this one too... and it didn't break).Verbatim PLA Red 3mm filament prints inconsistently. Kind of surprising considering how long Verbatim has been in the plastics business. I printed one of those heart gear models for my wife. I had to print in several jobs due to my 6x6x6" footprint. Some of the prints have bubble pops, misalignments and rough surfaces (while some prints came out perfect). I used the temperature they specified, every time, so I can only chalk it up to inconsistencies in the filament. I didn't take a hammer to this one, so can't say.Now granted ABS and PLA are very different plastic, I can still say I have had NO issues with IC3D filament, so I can recommend it thoroughly.I must thoroughly recommend getting a iGauging caliper if you are going to be modeling and printing your own 3D models to match up with real world objects. The IC3D filament and the LulzBot Mini printer and the caliper tied together perfectly, matching up to the millimeter.

I am eating some crow. One star to Five star. It turned out that I had a moisture problem. I have stored all of my filaments in a 2.5 Gal. Hefty Jumbo bag along with 2 10g silica gel packs that I had heated in an oven @ 250deg F for over an hour. I have had awesome results with IC3D filament except this particular spool of blue. After a number of failed prints, I concluded that the filament wasn't any good. After writing the review below, I contacted IC3D. They are super awesome. They sent out a replacement spool right away. However, in the interim, I ordered some of these:ShieldPro Humidity Indicator Card 10-Pack 10-60% 6 Dothttp://www.amazon.com/gp/product/B004B7E022/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1Out of curiosity, I put one in the bag with the blue IC3D filament. Even though it had 2 10 gram desiccants, it indicated quite a lot of moisture! I put some newly dried out desiccants in with the filament and let it set for almost a week to let it dry out well (as indicated by the ShieldPro). Tonight, I am doing a 3 hour print and none of the problems I have had previously are present. To be clear, this is with same the filament I had complained and not the replacement spool. So, the orginal spool was fine and it was my fault all along. As to the spool IC3D sent me as a replacement, I am going to pay them for that. I would have ordered another spool anyway as it is an great color. The ShieldPro Humidity Indicators are great too!Original review:This stuff is garbage. I have not gotten one single thing to successfully print with it. I am not digging on IC3D in general, just this blue stuff. I think that it has inconsistent diameter. What happens is I have several (maybe 10 layers that are not feeding right and the object will just pull apart like it was perforated. These layers will go through all the items in the build. This has happened with every single print. This roll is going in the garbage. I have bought 4 other rolls and those are fine (I haven't tried one yet). I have been very happy with the other colors and have gotten fantastic prints with it. It is a shame to throw away 3/4 of a spool. Well, actually, 100% of it has actually went in the garbage.

works great
