Let it dry for a few minutes until it has a hazy appearance to it.Īt some point, Aqua Net became the de facto 3D printing hairspray.Īny hair spray will do. I recommend removing the bed before doing this so you don't cover your printer in sticky hair spray. Simply spray a light, even coat across the entire thing - similar to how you would with spray paint.
Hair spray is a tried-and-true method for getting good bed adhesion. You're going to run into issues with adhesion.
While it is possible to use a glass bed on an unheated printer, I wouldn't recommend it.
HeatĪ heated bed is key to printing on glass. There are a few ways to make sure your prints stick nicely to your glass bed: the magic formula is heat and hair spray or heat and glue. A proper borosilicate glass bed is very inexpensive (more on that later). Some people have cut inexpensive soda-lime silicate glass panes or IKEA mirrors to size for use on their printer and have experienced success for some time with them this doesn't mean that they're safe to use, nor does it mean that they will last a long time. You probably shouldn't have Home Depot cut your bed for you It's consistently smooth and flat and doesn't contain bubbles that can cause the glass to fracture or explode while heating. There's a reason scientists choose this type of glass: it's highly resistant to temperature changes and chemicals. Go with borosilicateīorosilicate glass is the same type used in labs for beakers and other neat labware. Therefore, it's important that your bed not explode with sudden temperature changes.Īdditionally, cheap glass like soda-lime silicate can contain bubbles when this glass is heated, the air in these bubbles can expand and shatter the glass. Your glass bed will rapidly cool or heat when your heated bed is activated, when the extruder comes into close contact with the print surface, or when a print finishes in a cold environment. Thermal shock resistance is the ability of a solid to withstand sudden changes in temperature during heating or cooling. It is essentially the ability of a solid to withstand sudden changes in temperature during heating or cooling. Thermal shock resistance is an important property to consider when choosing a glass for your bed. Industrial equipment, exterior lighting, laboratory and kitchen glassware Glass Typeįood and beverage containers, windows, lamp envelopesīone scaffolds, optical fibers, heat absorbers Windows, glass jars, and lab equipment all use different types of glass with different properties. There are several types of glass that you can use for your bed - and several types of glass in general. Glass will always remain flat and smooth, will always love you, will never give you up, and will never let you down. A high quality glass bed is supremely flat, hard, and rigid Lastly, repeated print and bed heat cycles can warp your aluminum build plate further. Thus, you end up with an imperfect print with poor layer adhesion and quality. If the bed isn't flat, the center of the cube doesn't exist on the same exact plane as its edges. When your 3D printer is laying layer after layer of filament to form your print, it's very helpful if the distance between the extruder and bed is identical for the entire layer, right? Well, it's about a lot of other things too, but tolerances and precision are really important. This is just the nature of thin, machined, often mediocre-quality aluminum. It's probably made from aluminum and, even when new, is slightly bowed toward the center or edges.
