Stratasys printers offer a wide range of material options across their FDM product line. These materials are all true thermoplastics that are common to many traditional forms of fabrication (i.e. ABS, PC, Nylon, Ultem). The majority of FDM printed parts are used for prototyping, jig, fixtures, tooling and end-use applications. In these settings, it's common for the 3D printed parts to come in contact with various chemicals. This means when deciding which material is the best fit for an application it's important to not just look at the strength of a particular material (tensile strength, impact-resistance, elongation at break, etc.), but we must also look at how a material can hold up to potential chemical exposure.
