Magigoo – The 3D printing adhesive, MO2016

Product Information

It doesn’t matter if you’re using PLA, ABS, PETG and more - Magigoo works for them all Easy Clean-Up

In the next part of this series we will go into further details on how to prevent this warping effect. Make sure not to miss it. In the mean time: Recommended Magigoo Printing Settings This is part 3 of our 4 part blog series. This series is about warping and how to optimise your 3D printer’s bed temperature and increase your first layer adhesion to reduce this effect. In part 3, our chemist Jean Paul Formosa, will discuss how to determine the best 3D printing settings for minimum warping. How to determine the best 3D printing settings for minimal wapring 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? 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.

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 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. At Magigoo our aim is to help make your bed adhesion issues a thing of the past by suggesting the optimal settings for reliable bed adhesion each time. Unfortunately, every FDM printer and its environment is different so different materials will require different printer settings for optimal adhesion.

Excellent layer adhesion: Parts printed in PP tend to have very good layer adhesion and are rarely prone to layer splitting Turn off the heated build-plate after the first layer: Some PP materials such as Owen’s corning GF30-PP warp noticeably less when the heated build-plate is disable after the first layer. This helps anchor the material better to the build plate thus arresting warp! If 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. In the past two blogs in this series we have discussed what moisture is in regards to polymers, and how this affects 3D Printing filaments and printed parts. In this third blog post in the series, we will be delving into the methods to counteract such moisture, specifically drying filaments. If done right, drying can make moisture filled filaments viable for printing again.

What is Magigoo?

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 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.

PET – Polyethylene Terephthalate or CPE – Co-Polyester type materials describe a number of polymers which can vary significantly in chemical composition and thus in physical and chemical properties. As a result different CPE/PET type materials might require different printing settings.The bubbles seen when extruding a filament with moisture present is one of the main problems that moisture creates in 3D printing. These bubbles occur due to the water (moisture) trapped within the plastic. When the nozzle heats up to temperatures over 100 °C, the water vaporizes and expands, creating a series of bubbles in the filament. The bubbles create voids in the heated filament strand, which causes a variety of problems when it comes to 3D Printing. PP or polypropylene is a very popular plastic in the industry. It is stable, durable and relatively cheap. Since it is difficult to print and cannot be processed by cheap 3D printers, it is all the more important not to produce misprints. 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

There are various methods and tools that one can use to dry their filaments, and they vary in effectiveness, reliability and cost. We will now go through some of the most used drying techniques and mention their pros and cons in regards to cost, reliability and how well they dry filament. Using a Printer’s Build-PlateIf the warp continues increasing on the next increment for the build-plate temperature, one can safely assume that further increasing the temperature beyond that point will cause the print to warp even more. Thus one can stop increasing the build-plate temperature. This is Magigoo PPGF, the adhesive specifically designed for 3D printing on glass-filled polypropylene plastics. Magigoo PRO PPGF is the stronger cousin of Magigoo PP, offering stronger adhesion for the stiffer reinforced polypropylene blends. Magigoo PPGF requires the bed to be heated for easy and safe removal of parts. Since the combination of PLA and a glass print bed is very common, I compared the print bed adhesion with and without Magigoo. Printing with wet filament may also present visual differences in the extruded filament and printed parts. The filament will be more prone to stringing, and may have a slightly bleached colour. The final print often also has a softer texture than a print with dry filament. Properties of Parts 3D Printed with Wet Filament Low density: PP has one of the lowest densities of any of the currently available FDM thermoplastics
