BuMat PLA 1.75mm, 1kg, 2.2lb Translucent Blue Filament Printing Material Supply Spool for 3D Printer PLATB

Currently printing at 245C. with the HBP set at 115C. At 230-240C. (Tried at 5C. increments) it really didn't want to stick to itself and had insufficient hold on a very clean HBP set at 110C. (Straight undoped Kapton)Update: Printed a couple of overly complex, undersized tests that yielded more support material than the tiny fragile objects. But they completed so I tried something larger (A goblet). Estimated 7 hours 10 minutes project ceased to build at about 5 hours. Stopped extruding thread. I thought clogged nozzle (Running the ABS at higher than advertised temperatures was producing occasional brown flecks). Turned out to be broken filament though. Trying again. (I thought that it might be the filament being brittle at first but it was not. Issue was mechanical at my end that caused fractures in the filament, not the product.)Second attempt on the goblet succeeded (See customer images.) It's not exactly white but wasn't quite as 'Clear' as I had hoped (I wasn't expecting glass.) but it was OK. It has more of a silvery sheen on the surface with some translucent properties. The customer images are reasonable examples of the results thus far.

I bought this filament to make a gold statue for a costume, and wanted to use gold material rather than painting something else. It was just a few days before Halloween, so I expedited shipping. It arrived the next day as expected and was packaged well.The first thing I always do with filament is inspect it. Using my digital calipers, I found a lot of variation in diameters, ranging from about 1.61 up to 1.76, with some of those variations only a couple inches apart. I was pretty disappointed, since I needed this stuff for my costume. I ran a quick test print and it seemed to work out ok. I jumped right in and set it up to make the statue and let it run overnight. The next morning, I had a really nice completed model! I had used a relatively solid infill (30%) and had put another fan to blow on it which could have helped, but I was really impressed with the results. It seemed to adhere to my heated glass bed really well without much tweaking, and produced a surprisingly great print, even better than some of my recent other prints. The gold color was vivid and even had some glisten to it, which turned out nicer than expected. After working about 14 hours into the material and measuring it again, I was finding it closer to 1.74-1.78, which is much more reasonable. Overall I'm quite happy with this filament, and will keep it in mind for when I need more.

So far, so good for me, using it in an XYZ Davinci 1.0. As other reviewers have stated, it is very brittle, the reason for a 1-star loss. But as long as you situate the spool in a good location that prevents sharp bends while feeding, you should have no problems.Personally, the only breakage I've had was when I was first setting up my printer to take external filament, and this spool was the one I used when I did it. Since installing, I've printed about 140m from this spool so far and have not had a single break.Print quality is pretty good, with no major issues. I use ABS "juice" table primer (ABS + Acetone; 1mm:1ml) and have zero issues with lifting or shifting.Review update: I had shelved this filament for about a year as I had no need for clear and just this past week started using it again as I had a huge project come up. The first print I made came out great and then, as others have stated, everything fell apart. My extruder kept jamming mid print with that ominous "click click click." After several hours of troubleshooting with no results, I popped in a spool of a different brand/color and it printed like normal.I'm assuming this is diameter inconsistencies. I wasted a good bit of this roll, and now it seems that I'm just going to have to pitch it anyways since I can't use it without jamming. Such a shame, since I gave this a rather positive review upon my initial use of it.However, this roll was purchased in 2014, so it is possible they've corrected the issue by now.

I haven't found this filament to be as brittle as some other transparent filaments unless it gets cold. Transparency is very good and so far it hasn't had any knots when unwinding. Here's more information on the clear filament and the brittleness problem. Only the last few inches of the spool become brittle and the easiest thing to do is to unload the filament and just break off the brittle part. The white PLA does this as well and it's easy enough to work around.But I discovered a bigger problem when I reordered the clear PLA, they sent a different filament which was translucent and not transparent like the last spool (calling it "clear" is somewhat ambiguous). I kept it sealed so I could return it, but they told me it would be the same after it was heated. They were wrong, the package is now open because that's what they told me to do, and they aren't responding to my messages any more. It's too bad, the original clear was good but I don't trust the vendor and will take my business somewhere else. Be careful if you use "Shop 3D Supplies", maybe you'll get lucky, maybe you won't.

I like the less-translucent stuff better because it prints smoother. Less tendency to jam/leave a bunch of cobwebs everywhere. This isn't down to Bu-Mat, but a problem with filament in general. Natural PLA prints like butter, but when you start adding these colorants it changes the material properties - and then you get more problems with jamming, stringing, poor surface finish, etc.This red stuff does run through my hot end nearly as well as natural PLA, which is a good thing.What isn't a good thing: I ordered red, but got grey. The label they stuck on the outside of the vacuum bag says red, but the label on the actual spool says grey. I've attached photos.

I'm Using a Makerbot Replicator 2 which runs at 230 degrees C; This filament worked well for a 2x - 2.5 hour print I ran 2 days ago, no plugging, nothing weird, good resolution and no odd surface defects at a 0.3mm resolution. There was a little shrinkage, but it was easily mitigated with a second print set with raft support and enclosing the printer to keep the heat in (its winter where I am and I'm next to a window...). But the oddest thing happened about 5 minutes ago ; The chord sheered off at the feed tube as it was just sitting on my desk ... with no outside influence, no touching or vibration. This is a first for me. Now I will have to check if the chord is intact prior to printing in the future to avoid a miss-print.Thought I would note that odd little thing to maybe prevent a miss print for other makers that may experience this ... its probably a good thing to check prior to running a print anyway .......... other then that, it seems to work great. I haven't had a print long enough to watch for dis coloring. But this was bought for mold making and painted parts anyway so I might never really care to notice.

I quite like this Filament, it has worked well for me ever since I got my printer. It prints really well. The only issue I have with the filament itself is that if I leave it in the printer after a print , it will snap somewhere between the spool and the extruder. I've never had this happen during a print however, even 24 Hour + prints have worked with no issues.The only other issue I have is that I've just ordered my 4th spool this ,and the spool is much skinnier and a larger diameter than previous one's I've received ( previous ones were as pictured, latest one was not ). I thought they'd sent me a 0.5kg spool at first. The change was unexpected and quite annoying since my filament holder was custom made to fit the old spool width, and the new spool does not fit on my holder.

I'd rate this filament as OK, but not great. If you're using it for prototyping smaller objects and you're not on a deadline, it's fine. However I found the roll had a section that was way fatter in diameter than 1.75mm, probably 2.3 as another person mentioned, and the roll had a kink. this resulted in 2 long 10 hour prints being wasted when the printer jammed on the fat section, then when attempting to print again, it jammed on the kink in the spool, which was time and filiment down the drain. That being said I might buy again and just use it for smaller parts, it's a good price.

The prints have generally turned out pretty good. I've been printing on a Printrbot Simple Metal.The bottom of the print tends to warp and lift more than I've experienced with other PLA.The spool had a few tangles which starved the print head, so I usually have to babysit prints.Occasionally, the filament will just break for no reason. I only had one break during a print, but I have had to replace the filament in the print head before a print several times.Overall, it's not bad for the price, but you get what you pay for.

El color Silver difiere mucho de la foto, en realidad es totalmente plateado. Tengo PLA y ABS de esta marca, el PLA requiere una temperatura de 210º para extruirse correctamente y 60º para adherirse a la cama, mientras que el ABS requiere una temperatura cerca de los 250º para extruirse y 110º para adherirse a la cama, ambas temperaturas muy por arriba de otras marcas de filamentos.El material es de excelente calidad, muy consistente en el diámetro aunque si no cuentas con cama caliente en tu impresora o no alcanza la temperatura requerida, será imposible que logres una impresión correcta.
