Fused Deposition Modeling (FDM) is a 3D printing technology that builds a part layer by layer by depositing heated thermoplastic along an extrusion path.
We’ve put together this mini-guide to help inspire and inform your decisions when designing for FDM 3D printing.
ABS is a strong and stable production-grade thermoplastic available in a wide range of colors and material properties.
Polycarbonate (PC), one of the most widely used industrial thermoplastics, offers high tensile and flexural strength.
Nylon 12 is widely used in traditional manufacturing for its excellent value and offers the best Z-axis lamination and impact strength of any FDM thermoplastic.
Ultem is a high-performance thermoplastic known for its reliability and excellent mechanical, thermal, and chemical properties.
Design Tip: Infills
Infill describes how a solid part should be filled with material during the build process. Xometry offers 3 infill options with different properties.
Xometry’s Ultralight infill parts are filled with a single cross-hatch pattern. This is the lightest and least expensive infill option.
Xometry’s Light infill parts are filled with a double cross-hatch pattern. This option provides increased rigidity and is lighter than a complete solid infill.
Another feature unique to Xometry is automatic and instant quoting on 3D printed orders. Just upload a 3D CAD file and select a 3D printed material of your choice to price your order. Trust us, it’s as easy as it sounds.
