The following solution article is provided to help ABS users get better quality prints.
◄About ABS Filament►
ABS is a combination of three different plastics; Acrylonitrile, Butadiene, and Styrene. How they are mixed and in what percentage is usually directly related to their intended use. You will see many different kinds of ABS in the marketplace and you can seek out formulations perfect for your application.
MAXX ABS is a mainstream mixture that achieves strength and quality of print. It is very tough second only to MAXX Nylon. It makes excellent structural pieces that can easily be drilled or tapped for bolts and screws. It has good resistance to heat once it is printed which can also make it a good choice for some projects requiring that. It prints extremely well since you don't need to worry about ABS dripping/oozing from your nozzle due to it remaining fairly viscous in the extruder nozzle as it outputs.
It is important to use a MAXX Perfect-Print sticker on your print bed so that you gain excellent adherence to the surface for your first printed layer. Due to a high rate of thermal expansion, which basically means that ABS expands quickly as it is heated and shrinks quickly as it is cooled. The trick is to make sure the object your are printing as a whole heats and cools at roughly the same temperature so that any expansion or shrinkage is relative to the entire object. Doing this will ensure you avoid issues from warping and cracking. ABS bonds its layers together best at high temperatures however printing at higher than standard temperatures increases the chance for warping and cracking.
If you want to achieve a high quality, very strong MAXX ABS print it is best to print it with our Leapfrog XEED printer which is fully enclosed and is built to mitigate the issues of warping and cracking. However many users find that simply covering the front and partially covering the top of our Leapfrog Creatr Series with some kind of plastic to keep the heat in produces excellent ABS prints.
◄MAXX ABS Printing Tips►
-Your extruder temperature should be 235 degrees Celcius +/- 5 degrees depending on the color of the material, some experimentation may be necessary.
-MAXX ABS requires a heated print bed as all ABS varieties do. You should set the bed to about 85 degrees Celsius, +/- 5 degrees
-To minimize thermal expansion and it's side effects it is best to drop the temperature of the bed a bit (10 degrees) after the first few layers have successfully been printed, especially if your bed was set to 90 degrees or higher.
-If you are using a open bay printer like the Leapfrog Creatr Series, use any kinda of disposable plastic wrap to wrap around the machine to seal up the front opening to really help keep the environment warm to avoid warping and cracking of your print. For serious ABS users, you may want to purchase a dust cover (if you own a Creatr HS) from our website, or design something similar.
-If you still experience warping, try printing with a raft or a brim.
