spray adhesive for perfect adhesion to the 3D printer print bed, 400 ml

Over the years I've used a lot of the suggested hacks for keeping prints stuck to the bed with middling success. Painters tape used to be my preferred method until they changed the formulation of the brand I used and it stopped working. Since then I've struggled finding another brand or method that would work as well and usually I have had to make design compromises to reduce warp forces (no sharp corners, low infill etc) to keep prints stuck down. Finally, I think my long search is over. This stuff is excellent and keeps prints firmly stuck down. It is quite expensive, but you don't need to use very much and providing you aren't printing something large, you can adjust print positions to use fresh areas of the bed before having to respray. Another cost saving boon is that this will work with a cold bed (only currently tested with PLA). With the ridiculous energy prices nowadays, not having to heat the bed will likely mean that 3D Lac will soon pay for itself in energy savings. Of course, there is always a bit of a double-edged sword with strong bed adhesion, and that is getting the prints off afterwards. I find that I do have to prise prints off the bed with judicious use of a tissue blade to get under the print. Saying that, my previous struggles with keeping things stuck on the bed has meant that I have adopted very aggressive first layer settings with a very small print gap so that the first layer is firmly squished onto the bed. Personally, I much prefer having to struggle to get things off the bed afterwards than face the waste of coming to the printer after a long print run to find a tangle of extruded plastic caused by a print popping off the bed mid run.

This stuff works great, my print bed had lost adhesion and nothing was sticking to it resulting in poor prints and lots of spaghetti. I just give it a quick spray with this each time and it works great, the print now sticks firmly to the bed. Your supposed to wash it off each time but I just speak more on and use again a few times before washing.

Wish I had found out about this sooner. Works well and never had a print fail due to lack of adhesion to bed since. Don't need to apply every print.

If you are looking for adhesive for your FDM 3-D printer, then this is the spray you want. Don't buy those little spray bottles that you see because they come out in splotches and most of it drips down your hands. This comes out beautifully. A nice even spray and brilliant hold. Would definitely buy again and will.

Got to say I'm impressed. I was printing some largish 200mm square parts and was getting a bit of lifting on a corner, which is pretty annoying when big prints eat so much filament!! Gluestick is horrible and takes so much cleanup from parts, especially when using a textured plate, so I thought I'd give this stuff a go. Glad I did, nothing but perfect adhesion and seems to easily come off with a wipe over with a damp cloth, not that you can see too much of it on parts anyway. All that's needed is a light coating and it lasts for a good few prints before reapplication is required. The can should last for a good long time, so not too bad value at all. Simple to use, doesn't smell bad and makes your prints stick!

This has worked exactly as expected with no issues so far. Adhesion is strong when needed and prints release cleanly once cooled. It’s easy to apply, consistent, and does what it says on the tin. I’ve used it across a few prints now and it’s been reliable every time. No complaints.

In my opinion 3dlac is the best product available for 3d print bed adhesion. I prefer this aerosol version over the others as it gives very even coverage. The product also lasts a lo g time as I don't necessarily spray before every print.

I bought a can of this 3DLAC soon after acquiring a Flashforge 5M Pro which comes with a textured PEI build plate. Certainly for PLA I needed an extra bit of stickiness to get around having to use Rafts and Brims a lot of the time. And 3DLAC has worked a treat. I went for the Aerosol spray version and have found it very easy to put just the right amount of "dusting" on to the build plate to achieve the level of stick required. The 3D prints stick to the plate and after printing are removable with just a minor flexing of the plate, where they release instantly. The spray has a pleasant smell to it. It goes on easily to the build plate, and washes off with mild soap and running water when needed to be cleaned. But generally I just reapply new spray over old. So far that has not been a problem. A handy addition to my 3D Printing equipment. I can certainly recommend this if you're having troubles with 3D adhesion.
