Magigoo – The 3D printing adhesive, MO2016

Product Information

Print slowly on the first layer: Most materials but especially PP tend to show better first layer adhesion when the first layer is printed slowly (10-20 mm/s) Thermoplastic materials of different material compositions achieve optimum adhesion with different adhesion products. PLA, ABS and PET-G adhere firmly to the Original Magigoo® adhesive when the build-plate is hot and are easy to remove once the build-plate cools down. In addition to the original Magigoo® adhesive which is suited for printing conventional FDM materials, the Magigoo® Pro range consists of four additional adhesives designed specifically for use with different engineering grade materials. Warping is cause due to several factors including the material properties and the printing conditions which are not independent of each other. One of the most important material properties governing the amount of warp in a print is the CTE (coefficient of thermal expansion). The CTE describes the tendency of a material to change its shape, area and volume as the temperature changes. A material with a high numerical value for linear CTE exhibits large changes in length as a response to temperature change. As a result materials which have a high CTE are more prone to warping than materials which do not exhibit large changes in dimensions during the thermal changes present during FDM printing.

Secondly some printers tend to have the build plate colder at the edges, especially in non enclosed printers. This can lead to prints lifting towards the colder areas of the build-plate. In this case the warping can be controlled by using an enclosure or by increasing the build-plate temperature. 4. What is the best adhesive for TPU/TPE/TPC? Drying is the process of removing water molecules from the polymer chains. There are a number of ways that water can be removed from filaments, and these will be explained in the next section. Drying can be quite simple and cheap to do, if you have the right environment and parameters. Most drying techniques involve heating the filament to a temperature below the Glass Transition Temperature. The heat excites the water molecules that have bound to the polymer and allows them to move freely and diffuse to the surface. It is important that the Glass Transition Temperature is not exceeded, as this could irreparably damage the filament. The temperatures that each material is best dried at can be seen in the table below. Material Start high then go low: All PP materials benefit from using an additional 10 ˚C for the first layer on both the build-plate and the nozzle. This helps the first layer adhere better but prevents warping and other problems related to excessive printing temperatures. It doesn’t matter if you’re using PLA, ABS, PETG and more - Magigoo works for them all Easy Clean-Up One of the most used techniques, especially for DIY hobbyists and small companies, an oven is a simple, easy way to dry your filaments. Using an oven requires you to preheat it to the specific temperature that you want to dry your filament in. It is important that you monitor the oven with a temperature probe inside the oven. This is because ovens have a tendency to overshoot the temperature the first time that it is heating up. The fan assist feature on ovens aids the drying and improves heat distribution. Once the oven has heated to the right temperature, the filament spool can be placed in the oven. When the time is up and you are ready to remove the filament from the oven, the best practice is to first switch it off and leave the filament to cool down slowly in the oven.To best remove the printed flexible filament from the printing plate without causing damage, you need to soak the entire printing plate in water for about 30 minutes to 2 hours. After that, the printed object should be very easy to remove. Magigoo PRO HT Since the combination of PLA and a glass print bed is very common, I compared the print bed adhesion with and without Magigoo.

The Magigoo Pro Metal is specially designed for the BASF Ultrafuse® 316L filament. To print this metal filament it needs a very high print bed adhesion to avoid warping. In some cases the use of different printing surfaces might require that the first layer settings are tweaked accordingly. Using the appropriate Magigoo adhesive will still increase the first layer adhesion capabilities of the build surface, however, some materials might show a noticeable drop in performance when compared to using Magigoo on glass with the same material. 2. Which Magigoo adhesive and printing settings should I use? MaterialIf the material you are printing tends to warp, apply a coat of Magigoo and let it dry. Then apply a new layer of Magigoo on the printing surface. If there are still traces of glue, you can use rubbing alcohol or ethyl alcohol to finish cleaning the printing surface. Another way to obtain a smooth glass like finish is to dilute the Magigoo application slightly when applying. This can be done by dropping or spraying a couple of millilitres of water whilst smoothing out the Magigoo application. Magigoo adhesives are concentrated so that they last longer, this however makes them quite viscous. Thinning out the Magigoo will make it easier to spread into a thin smooth layer. How much Magigoo should I apply? Whenever you finish a printing process, apply Magigoo again, both to ensure the correct adhesion of the piece and to protect the printing surface from damage when removing the piece. Magigoo Original, PA, PC, Flex, HT and Metal can be easily cleaned by wiping off with a damp cloth followed by a dry paper towel to remove all residues. In some cases if the Magigoo layer is left on the build-plate for a very long time it can harden and would require a light scrub with a sponge and some warm water to remove.

Use a brim: For the majority of PP prints a 10-20 mm brim is an absolute necessity for a successful print with little to no warp

So if you have problems with print bed adhesion on a glass print bed, Magigoo is the perfect solution. I was really amazed at how strong the adhesion actually is, even though you couldn’t see that much adhesive on the glass surface. Magigoo Types Make sure that the printing surface is free of residues such as dust and filament residues, as well as oils and adhesive residues. Some filament types require very precise temperature control: Some filaments are very prone to warping and might require additional experimentation with cooling settings for optimal results. After this, one can perform the same test using the same settings at different build plate temperatures in steps of 10 °C above T0. At a certain stage of printing, the amount of warping of the test print at a higher temperature will be visibly more.

In some cases vigorous shaking can trap bubbles in the adhesive. If you wish to avoid air bubbles whilst applying Magigoo wait for a few seconds for the trapped air bubbles to dissipate before applying. What if I want a smoother Magigoo application? Smooth it out with the applicatorMagigoo for Polycarbonate can be used on glass or a multitude of other surfaces. To provide maximum adhesion and prevent printed parts from fusing to surfaces, it is recommended that Magigoo PC be applied to all plastic-based surfaces.
