ABS is a widely-used plastic renowned for its versatility in everyday items like plastic boxes, toys, and electronic device casings. Available in both 1.75 mm and 2.85 mm variants and in spools of 750 g or 3.3 kg, ABS Smartfil from Smart Materials offers exceptional functionality and adaptability to various projects, also thanks to its wide range of available colors, including black, white, red, yellow, blue, green, grey, and natural.
Unlike PLA, ABS Smartfil isn't biodegradable, and its vulnerability to UV radiation has spurred the development of ASA material as a UV-resistant alternative, highlighting the ongoing evolution within the realm of ABS-based materials. Furthermore, ABS has a high propensity for water absorption. When considering applications involving water containment, alternative materials may be more suitable.
ABS is a polymer composed of three building blocks, acrylonitrile, butadiene and styrene, which is why it is called a terpolymer. Each of the three building blocks provides different characteristics. Acrylonitrile provides rigidity, resistance to chemical attack, hardness and high temperature stability. Butadiene, especially low temperature toughness and impact strength; and styrene, mechanical strength, stiffness, gloss, hardness, toughness, and impact resistance.
Parts 3D printed with the ABS Smartfil filament can be machined, polished, sanded, drilled, drilled, painted and glued with extreme ease, maintaining a really good finish. If you want to obtain extraordinary surface finishes, we recommend the use of the XTC-3D coating specifically designed for 3D printing. ABS is also soluble in acetone, so many 3D printing users use acetone vapour baths to obtain smooth and shiny surface finishes.

3D printing with filament ABS is a bit more complex than the PLA filament. In the case of Smartfil ABS filament is necessary that the print base is hot about 60 °C, unlike other ABS standards on which this temperature should be between 80 and 110 ºC, so printing ABS Smartfil is really easier. In addition, the extruder temperature should be around 240 °C depending on the color used. Also worth remembering that the ABS plastic undergoes the phenomenon called "warping" which causes the first layer of the pieces off the base of the 3D printer. So if you are printing large pieces it is advisable to use BuildTak, Kapton Tape, DimaFix, Magigoo or 3DLac so that the pieces do not tend to detach from the base.
It is also advisable to set the "raft", which is to create a first thick layer, such as media, who will not suffer that contraction and on which to print the piece. The disadvantage of using the "raft" is that this first layer will have a less smooth. It is advisable to lower the density of "infill" parameter for the part to store less heat. As for the "brim" (the membrane that is created around the piece) parameter is recommended to set it to never greater thicknesses of 5mm to help the first layer will not peel.
If you need to print very thin and tall pieces, you'll notice that the ABS plastic doesn´t give you enough time to harden in each recording layer and therefore the piece is as if it had melted. To solve this problem we give a very simple advice, it prints at the same time at least two pieces, and place them separate at the base. Thus while the extruder is moved from one room to another in each recording layer, the plastic will have enough time to harden getting a much better result. As for the interior temperature where printed it is recommended to be controlled and no drafts. Finally remember to use your 3D printer in a well ventilated room as the fumes released during printing filament ABS are not entirely healthy.
