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

3DLAC is an absolute must-have if you operate on a smooth bed, but it is also great on textured plates. I tend to use a textured plate that is getting old and starting to lose its adhesion, but a quick spray brings it right back. You only need an occasional light dusting, so a single can lasts ages. It holds up exceptionally well even when heated to high ABS bed temperatures (typically 90°C to 110°C) with zero adhesion issues. Just be careful not to spray too heavily—applying too much can make the grip almost too strong and cause dark filament colors to leave a slight residue that might transfer onto a subsequent white print. There are a few comments in other reviews about the smell. I found that it does have quite a strong odor when spraying—it is not particularly unpleasant, but you definitely wouldn’t want to breathe it in, so spraying in a well-ventilated area is a good idea. At 400ml, the can is massive and fantastic value for money. Whether you are running glass, smooth surfaces, or pushing high-temp materials on an aging textured plate, keeping a can of this next to your printer is a must!

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.

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.

My 3D printer has a removable PEI sheet but some prints still lost adhesion. I cleaned the bed with alcohol and washed it with washing up liquid and some prints still failed even with a brim. Tried experimenting with bed temps but never found out why prints came loose. Bought this adhesive and it stopped my failed prints, never had a loss of adhesion since. TBH cleaning the PEI sheet with washing up liquid fixed most problems but if you have a smooth bed then this would work even better.

Brilliant stuff. Easy to apply, easy to clean off and has never failed to make print adhere perfectly. Couldn't ask for better.

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.

I have previously used "stick" type adhesives with very limited success; in addition they are messy. So I tried this aerosol and have to say that I am amazed at how good it is. I have applied it just once and have since built many models, none of which has detached during building. It works really well with both PLA and ASA.

Needed to stop my ABS prints detaching prematurely (just can’t get this batch of abs to stay put despite 100deg slow no fan big brim etc). Bought some of this cos it is on Prime next day, did test print with no brim and print is perfect. Easy release when plate cold and no mess.

Ich hab den 3DLAC Sprühkleber (400 ml) über mehrere Druckjobs hinweg im Einsatz gehabt, und wenn es um eines der stillen, aber entscheidenden Helferlein im 3D-Druck geht, dann fällt dieses Produkt ganz klar in die Kategorie „macht, was es soll und zwar zuverlässig“. Was ich sofort mag: Die Handhabung ist einfach und vorhersehbar. Leichtes Aufsprühen, kurz trocknen lassen, und das Filament haftet sehr gut – gerade bei PLA oder PETG spürt man den Unterschied, wenn die erste Schicht sauber und plan am Bett sitzt. Kein lästiges Nachjustieren der Druckbetttemperatur, kein „Ränder heben sich, Mitte bleibt kleben“-Drama mehr. Gerade bei großen oder flachen Drucken ist das ein echter Komfortgewinn. Der Sprühnebel verteilt sich fein, ohne gleich eine nasse Pfütze zu hinterlassen. Das sorgt für gleichmäßige Auflagefläche, ohne dass man hinterher Stunden mit Reinigen oder Abkratzen verbringt. Und falls doch mal zuviel drauf ist: Mit etwas Wasser oder einem feuchten Tuch lässt sich das nach dem Druck recht einfach entfernen. Die 400 ml-Dose reicht erstaunlich lang – ich drucke regelmäßig und habe bei weitem noch nicht die Hälfte verbraucht. Das ist angenehm, weil man sofort merkt: So ein Helfer wird nicht zur Einwegware, sondern bleibt länger im Werkzeugkasten. Fazit: Ein solider Sprühkleber für bessere Haftung auf dem Druckbett, der zuverlässig und ohne großes Gefrickel funktioniert. Besonders bei anspruchsvolleren Drucken oder wenn du öfter mit Materialen arbeitest, die nicht von allein anbetten wollen, kann 3DLAC wirklich den Unterschied machen zwischen „läuft sauber“ und „Stop-Spiel“. Im 3D-Druck zählt die erste Schicht oft mehr als alles andere – und dieser Sprühkleber sorgt, dass sie nicht zur nervigen Hürde wird.

Werkt zo fijn met mijn 3d printer aanrader!

Very good product! Strong adhesion, easy removal. Makes a beautiful coating which is adored by first layers.

Snabb leverans.Mycket bra produkt.

Très pratique pour améliorer l'adhérence des impressions 3D sur le plateau. Je trouve particulièrement utile de l'avoir sous la main lorsqu'on utilise plusieurs plaques ou différents types de surfaces, car certaines adhèrent mieux que d'autres. Le spray permet de sécuriser l'accroche et d'éviter ainsi de rater une impression simplement à cause d'un problème d'adhérence. Pour quelqu'un qui imprime régulièrement en 3D, c'est vraiment le genre de produit qu'il est intéressant d'avoir dans son matériel. Un produit très utile qui peut éviter pas mal de mauvaises surprises et de temps perdu sur des impressions ratées.
