Product Information

Although pricier, a multi-function glue offers more than just bed adhesion, and can save money buying a separate glue for attaching 3D printed parts together. Many specialty glues struggle with filament coverage, for example Gloop! glues only handle a single filament. Other glues work with some basic filaments like PLA, ABS, and PETG, but struggle with anything beyond that, and Layerneer Bed Weld can run into issues with TPU. Another user who owned a PEI plate stated that he preferred to put a layer of glue before each print he would make. Eventually, he changed his build plate and now he doesn’t use any more glue. Yes you can! The key is using PVA —PolyVinyl Acetate — which is used to make white glue, wood glue, carpenter’s glue and yes…school glue like Elmer’s. PVA is a type of rubbery synthetic polymer that can be dissolved with water. It’s also used in dissolvable support filament!

The first is fusing prints together, which is what Gloop! is mainly advertised for. But it can also be used to fix both over-adhesion and under-adhesion issues, as well as smoothing out prints in post-processing. Remove the object: Once the print is finished, wait for it to cool down completely, then remove with a spatula. That’s because the ‘purple’ totally dissolves in water and it washes off cleanly. Users think that part of the appeal is that it is not as strong as some of the other white glues.

This means that you’ll typically have glue on your paper craft that won’t be covered up by another piece of paper. When this happens, you want to make sure you have glue that dries clear. If you want consistent, worry-free results, then Layerneer Bed Weldis for you. It’s a very utilitarian and no-frills option. Painter’s tape is even worse. It only works consistently on lower bed temperatures and is slightly harder to source than the other two. It’s the type of adhesive you should use in a pinch – not your go-to solution. Tragically, Elmer’s doesn’t work for every situation. There’s a complicated range of different factors that go into whether or not you’re getting good first layer adhesion, including the type of filament, your print bed material, the print in question, and your settings.

Keep a close eye on the initial layers of the print. Make sure that the layers of the object are adhering properly to the glue layer. If you notice any issues, such as corners lifting or warping, you may need to adjust your print settings or tweak the glue application for better results. So, considering the reliability and filament compatibility you’re getting, Magigoo is a solid secondary option to Layerneer Bed Weld – especially if TPU is giving you the most trouble. There’s little to be disappointed in (the applicator, mainly), and lots to love. Best Multi-Purpose Glue: 3D Gloop! It’s inevitable when working with a paper craft project that you’ll end up with glue in places you don’t want. Like Elmer’s glue, Magigoo cannot be used on a hot build plate. You’ll eventually damage the dispenser and make it difficult to get more glue to come out. If you ever create multi-part 3D prints, Gloop! can fuse them seamlessly. If you regularly feel annoyed with layer lines but don’t want to shell out hundreds for a resin printer, Gloop! can help with that, too. For more on this, we also have an article on the best glues for 3D prints.If you only get problems every once in a while and would rather spend your limited hobby budget on new filaments or cooler upgrades, it’s understandable to prioritize saving money. However, certain filaments like TPU aren’t supported. Layerneer reports a small amount of corner lifting with TPU on their internal warp stress tests, but some people have found a great deal of success with it regardless. Some glues can warp or damage the paper it’s applied to. Some common damages are crinkling, tearing, or discoloring the paper. Magigoo is technically re-wettable, just like Layerneer Bed Weld, it just isn’t advertised as such. If you fill a spray bottle with water, give it a couple of spritzes, and swirl it around a bit, you can use one application for multiple prints. To use liquid glue, first dilute it 1 to 1 with water in a cup or bowl. Then use a wide (cheap!) paint brush to apply an even coat of glue to your bed surface. Wait for it to dry before printing.
