PLA or ABS, which 3D printer filament should you use? We simply explain the differences and the fields of application of ABS and PLA Filament. When it comes to desktop 3D printing, two of the most common filament types are PLA and ABS. Both are thermoplastics, meaning they become malleable when heated. Yet, despite the ways in which these filaments are similar, they also have a great many differences. Let’s dive into the ABS-PLA comparison. 1 Polylactic Acid (PLA) is a biodegradable thermoplastic , made from renewable resources like corn starch or sugarcane. Outside of 3D printing, it’s typically used in medical implants, food packaging, and disposable tableware. The main benefit of PLA is that it’s easy to print . Acrylonitrile butadiene styrene (ABS) is an oil-based thermoplastic , commonly found in (DWV) pipe systems, automotive trim, protective headgear, and toys (like Lego!). Objects printed with ABS boast slightly […]
