ABS (acrylonitrile butadiene styrene) is one of the oldest and best-known thermoplastics in 3D printing. It\u2019s what LEGO bricks, household appliance housings and car parts are made of. Industry has used ABS for decades, and for good reason: the material combines strength, heat resistance and the ability to be finished well \u2014 things other popular filaments often lack.<\/p>\n
If you\u2019re choosing a 3D printing material<\/a> and need a part that can take mechanical loads or high temperatures, or that needs a smooth surface, ABS is worth considering first. In this article we look at its key properties, compare it with the alternatives and explain which jobs it suits best.<\/p>\n ABS withstands temperatures up to 100\u2013110 \u00b0C without deforming. For comparison, PLA starts to soften at just 55\u201360 \u00b0C. This makes ABS indispensable for parts that work near heat sources: mounts in a car\u2019s engine bay, electronics enclosures that run hot, parts of lighting fixtures.<\/p>\n ABS is a stiff but not brittle material. It absorbs impacts well thanks to the butadiene in its structure. Where PLA would simply crack, ABS deforms elastically and stays intact. This is critical for functional parts: protective covers, mechanical mounts, tool housings.<\/p>\n Unlike brittle PLA, ABS has a certain elasticity. This makes it possible to create clips, snap-fit joints and springy elements that won\u2019t break after a few cycles of use. Of course, for truly flexible parts it\u2019s better to choose TPU, but ABS has enough ductility for most engineering tasks.<\/p>\n ABS resists many acids, alkalis and oils. ABS parts can be used in contact with lubricants, fuel and household chemicals. That\u2019s another reason the material is chosen for automotive and industrial applications.<\/p>\n Each material has its niche. Here are practical guidelines to help you choose:<\/p>\n Read more about the differences between materials in our comparison of PLA, PETG and TPU<\/a>.<\/p>\n ABS isn\u2019t the easiest material for 3D printing, and you should take that into account when planning a project.<\/p>\n The main problem with ABS is significant thermal shrinkage. As it cools, the material contracts, which makes the edges of a part lift off the bed (warping) and cracks appear between layers (delamination). Large flat parts suffer from this the most.<\/p>\n Printing ABS well requires an enclosed printer chamber with controlled temperature. Draughts and sudden temperature changes are enemy number one. A chamber temperature of 50\u201365 \u00b0C significantly reduces the risk of delamination. Open printers without a chamber can cope with small parts, but for serious projects it\u2019s a compromise with unpredictable results.<\/p>\n When printed, ABS gives off styrene \u2014 a substance with a strong smell that can be harmful in high concentrations. Printing ABS in a living space without extraction is a bad idea. You need either separate ventilation or a printer with a built-in air filtration system.<\/p>\n When it comes to post-processing, ABS is unmatched among common filaments. Acetone smoothing is a technique that turns a layered 3D print into an item with a smooth, almost moulded surface.<\/p>\n The process is simple: the part is placed in an airtight container with acetone vapour for a few minutes. The surface dissolves at a micro level, the layers merge, and the part takes on a glossy look. The result isn\u2019t just aesthetic: smoothing improves watertightness and strengthens the surface further.<\/p>\n Besides acetone smoothing, ABS is easy to:<\/p>\n More about finishing techniques in our article on post-processing 3D parts<\/a>.<\/p>\n ABS isn\u2019t a theoretical test material. It\u2019s used in real projects every day:<\/p>\n Choose ABS if your part meets at least one of these criteria:<\/p>\n Skip ABS in favour of other materials if you need easy printing without an enclosed chamber (choose PETG), the part is decorative and takes no loads (choose PLA), or you need food safety (ABS isn\u2019t certified for food contact).<\/p>\n Printing ABS takes the right equipment, experience and control of the settings. If you have a project that needs strong, heat-resistant parts with a quality surface, we\u2019ll help you bring it to life. We work with industrial printers with an enclosed, temperature-controlled chamber, which guarantees consistent quality even for large parts.
