Nanopolymer Adhesive (50 Ml) - Ultimate 3D Printing Bed & Building Board Adhesion - No Mess, Non-Toxic, Works for Pla, Abs, Pei, Peek, Nylon, Pc and More. Easy

Goes without saying, this is the best build plate adhesive I've ever used. Fantastic adhesion. With a clean plate, and a good application of this stuff, I haven't had any issues with warping and lifting with any engineering materials I've used so far (PA, PC, PPS, PEKK, Igus, and more). The instructions recommend leaving "non high-temp" materials like ASA/ABS, PETG, on the build plate until it cools before removing the part. Having done this with some ASA-GF, I did scalp the PEI off my build plate, so maybe the adhesion can be a bit too good. My biggest gripe is the brush. For how much this stuff costs, the brush it comes with is a piece of junk. The packaging on the other hand was very nice. I would prefer they spend 20p more per item on a nicer brush, and 20p less on the packaging, seeing as one gets thrown away immediately, and the other is used every time I used the adhesive. I recommend getting some normal PVA glue or a fancier product like magigoo for day-to-day printing, and keep this stuff on hand for the fancier materials.

First, the good stuff. It works. Prints stick to the bed, and then get unstuck relatively easily after cooling down. For the most part. I have had a few occasions where scraping was necessary but that’s to be expected with some materials. The bad: mainly that applying the product is extremely awkward. The way they tell you to do is by drawing a cross and a circle covering the print area, then using the included brush to spread it. The “brush” is a tiny one, with half a dozen stiff nylon bristles. The adhesive is very liquid. The brush barely spreads it over a centimetre - it has no chance to spread it over the bed. After a lot of frustration and asking other users in online communities, I settled for diluting the NPA with 1:1 isopropanol in a spray bottle. 2 whiffs of that over the bed, then spread with a microfibre cloth. That works well and lasts many prints!

Okay, this stuff sounds like a scam, right? Buy a vial, coat your print bed, magically your prints work better. Huzzah! It works. I'm not going to claim this solves all print problems, because it doesn't. But it does *seriously* help with bed adhesion problems. If you're printing something that's finicky - say, an articulated robot with its parts connected by runners - this will take "frequent failures" and turn it into "rare failures". You might be worried about price; how long does one of these last? Well, I'd judge that coating *the entire bed liberally* uses maybe 2-5% of the bottle. So you might think "ugh I'll go through it quickly" . . . but you don't have to reapply it each time. Just reapply it when the bed starts sucking again. In my experience, this tends to take months. And I'll let you do the math on how long "5% of the bottle every few months" will last. Hint: It's a long time. This is a good product. It does what it claims and for a ridiculously low per-print price. It's a tiny bit of an upfront investment but not an overwhelming one. Strongly recommended.

I'm shocked that it works as well as it does. The advertising, surprisingly, wasn't full of exaggerated nonsense. This is the perfect bed adhesive for even filaments that seem to hate existing. The best part? It's somehow also water-washable. It just comes right off the build plate under the faucet. Unbelievable. Well-earned 5 stars for this stuff.

This stuff is like bed adhesion god mode. Its too sticky, it has lifted the pei off every plate I've used it on, and i've diluted it with ipa, tried removing hot and cold.... its just crazy how stuck prints are with this stuff. I dont really mind as most of the PEI i used it on was pretty well worn out, and for a few drops of this to rejuvinate it to the point of being too good, even when i've diluted it down 3:1 is impressive. Will definitely buy more when I run out in like 10 years.

I have only been using this for a day so I can't speak on long-term use, but I couldn't even get PLA to stick on a new print bed I recently started using. After using this stuff, I have been printing ABS almost non-stop with zero warping or adhesion issues. As others have said, it does leave a residue on parts, but I consider that as a very small trade-off for having parts actually stick. The residue washes off with soap and water.

I'm not new to 3d printer. I normally use cheap glue stick which works pretty well on PEI beds. Which is 8/10. It's affordable and works great. I recently got a new printer that's enclosed. Which prints on PEI bed, no issues with out glue. When I switch the bed to PEY (that smooth shiny stuff). For the life of me, nothing sticks. No turning up the temp, slowing down the print. I get a 1/20 successful print. I decided to give this stuff a try because I saw it on some random YouTuber's channel. OMG, game changer. This thing does not leave anything on your print, it does leave a little something on the bed. But man, I thought nothing I use would stick to the bed. Very few items I would give it a 10/10 score. This is by far the best one to use for your smooth surface beds. 50 ML is a lot and I should have gotten the smaller bottle because it's a bit expensive. I have two printers, and they are both 350 x 350 bed size, more than enough for both printer (since I don't put it on after every print).
