ABS: High strength engineering plastic, used for many commercial products.
Acrylic: A clear glass-like plastic. Good wear and tear properties. Great for outdoor use.
Delrin (Acetal): Resin with good moisture resistance, high wear-resistance, and low friction.
Nylon 6/6: Offers increased mechanical strength, rigidity, good stability under heat and/or chemical resistance.
PC (Polycarbonate): With almost twice the tensile strength of ABS, polycarbonate has superior mechanical and structural properties. Used widely in automotive, aerospace, and other applications that require durability and stability. Solid infill parts are fully dense.
PEEK: Offering excellent tensile strength, PEEK is often used as a lightweight substitute for metal parts in high-temperature, high-stress applications. PEEK resists chemicals, wear, and moisture.
