Layerneer could be the perfect bed adhesive.  I have been a staunch supporter of this product for about a year.   Layerneer has been a common topic on 3D printing forums.  It has its supporters, and this that do not think you should use it. I have used the adhesives for about a year, and I have a good amount of experience to base any suggestion that comes out of this article.  The purpose of this article is to post a review of its strengths and weaknesses and give you a suggestion on whether to use it.

If you anything like me, you have found that difficult to stick filament that just will not stick no matter what adjustment you make to the Z offset or how many times you clean the bed.  The best part about this adhesive’s claims is that it reports that you can also remove the prints easily once the bed is cooled.  I am fed up with my parts warping and coming off the build plate or over adhering to the plate when it is cooled.  I have tried glue sticks, and they do work, but they can be a little temperamental if you get them on too thick.  Then comes Layerneer Bed Weld to the rescue.

I have used a number of agents to promote and reduce adhesion.  My go to before Layerneer was Aquanet hair spray.  I am a bald man and I get some real interesting looks when i buy hair spray locally.  I have also tried Kore’s Glue stick that came with my printer.  I primarily use it for Polycarbonate Blend from Prusa.  Lastly, I commonly use Windex window cleaner as a releasing agent for PETG to reduced over adhesion and sheet damage from removal.  I have used countless other products but none match what I have found from these three products.

Bed Weld is a 3D printing adhesive developed specifically to resolve the technical challenges associated with building plate adhesion during prints while also hindering easy removal parts once the print is complete. The quite simply is limit failed parts several hours into a marathon print session and long intimate periods with a spatula or razor blade prying off parts that are stills emended to the build plate after it is cooled.  The goal is less damaged parts and fewer cuts to your knuckles and hands (see razor blades).  The product was designed for applying directly to glass printer beds, but as I have found, it works on PEI and Bondtech.

The benefit of these products is that they will keep the print stuck to the print bed.  We have all had that long print break-away from the build sheet.  This results in what JSW and many others refer to as the “Blob Of Doom”.  Who wants to have to clean up that mess.  Hows spent intimately connected to a heat gun using pliers and tweezers to remove the print.


The most challenging parts to get printed are large areas of supports and small parts.  The first layer of the supports can often entomb your hotend, nozzles, and the wiring to your heater and thermistor.  In my book an adhesive is a small investment to not have to clean that up or replace parts.  It only takes a small corner failing to stick to turn into a disaster.  The two top photos below and the start of the disaster and the bottom two show the perfect first layers of support. 


What is Layerneer Bed Weld?

It is listed on the MSDS as a harmless polymer. I am not sure what that actually is or just how harmless it is, but I would not recommend using it with eating or drinking implements.


The adhesive liquid is applied by a foam applicator on the tip of the bottle and allowed to dry as the bed heats. The product comes with a sponge applicator in the bottle, with a ‘push flow’ valve, as in hold the sponge end to the plate and push and the flow starts.  The instructions say to apply a ‘thin’ coat on the plate. I would recalibrate the Z height with the addition of the layer of Layerneer.

Who is Layerneer?

Layerneer is based in Palo Alto, California. The product is primarily sold on Amazon and in the United States. They are a Veteran owned company that focuses on a family atmosphere. Their stated mission is “to make products that deliver impressive results, we continue to further develop additional solutions for the 3D printing market”. The company started developing adhesives for 3D printing in 2017. Bed Weld – Original is their first product in a series of adhesives planned and specifically engineered to solve warping and first layer adhesion challenges. At the time of the post, it is their only product on the market.

Can it be used on PEI?

It was designed and recommended for Glass.  Many users have used it on Blue tape, Kapton, PEI, and Bondtac and have reported success. I am on one of them. Heck, I even added it to a plain steel bed and it worked. FYI, never put a steel bead against the Prusa heat bed. I used blue tape on the underside.

My experiences:

I have used 5-6 other adhesives, 50/50 Elmer’s Glue, and multiple glue sticks. I have used them on both glass and flexible steel beds with multiple sheets and have found them to work. I will post a comparison to Layerneer. The bottom line is that Layerneer is on par with Dimifix and Magigoo (for most filaments) and it is easier to clean.


  • Ease of use: 5/5
  • Clean up: 5/5
  • Adhesiveness: 5/5
  • Release on cooling: 5/5
  • Price: 4/5

The bottom line: This stuff is fantastic.  I know many of these products are made for glass.  They also work on PEI or textured PEI.  Layerneer goes on smoothly and cleans up quickly with soap and water.  It is not as east to spread at the spray on of Aquanet, but it is easier to control.  You cannot go wrong without Layerneer Bed Weld.
