ABS+ material is a type of filament, i.e. printing string, for 3D printers. It is based on the standard ABS material, which stands for acrylonitrile butadiene styrene, a strong and temperature resistant plastic. Conventional ABS is prized for its toughness, but printing it tends to be complicated by significant shrinkage on cooling, which causes the model to twist and peel away from the substrate. This phenomenon is referred to as "warping". The "+" in the name indicates that it is a modified version that suppresses these negative characteristics. Thanks to the added substances, so-called additives, ABS+ has a much lower tendency to shrink, which makes printing easier and more successful, especially for larger objects. At the same time, it often offers better bonding between the printed layers, which increases the mechanical resistance of the final product. In some cases, it can also have a reduced smell when fused. As a result, ABS+ is a material with mechanical properties similar to conventional ABS, but with a simpler and more reliable printing process.
