# Material Choice ### Aluminum Aluminum is lightweight and corrosion-resistant. It is easy to machine, stamp, weld, and drill, making it a popular choice for a wide range of applications, from parallel plates to electronics. It is very popular with FTC teams since it has one of highest strength to weight ratios for the price range. [See Aluminum Alloys >](/manufacturing-and-assembly/materials/aluminum-alloys.md) ### Steel Laser cut steel is a popular choice since it's the most cost effective metal for laser cutting. It's significantly denser than aluminum which makes it less popular for whole chassis, but it's still usable for a strong end effector part. [See Steel Alloys >](/manufacturing-and-assembly/materials/steel-alloys.md) ### Stainless Steel Stainless steel is a popular choice for a wide range of applications, its food safe, corrosion resistant, and easy to clean. Learn more about stainless steel and what sizes we can cut and form. ### Titanium Titanium is a high-performance metal known for its incredible strength-to-weight ratio and corrosion resistance. It’s stronger than aluminum and lighter than steel, though far more expensive. It’s best used in applications where strength and durability are critical, and weight is a constraint.\ [See Titanium Alloys >](/manufacturing-and-assembly/materials/titanium.md) ### Carbon Fiber Carbon fiber is a composite material that combines extremely high tensile strength with ultra-lightweight construction. While expensive and brittle under certain conditions, its strength-to-weight ratio is unmatched. Best suited for structural components where minimal weight is essential.\ [*See Carbon Fiber Options >*](/manufacturing-and-assembly/materials/carbon-fiber.md) ### 3D Printing Filaments Filaments offer unique flexibility for rapid prototyping and functional parts. From standard PLA and PETG to advanced materials like TPU or carbon-reinforced nylon, the right filament can provide strength, elasticity, or heat resistance depending on your design.\ [*See Filament Types >*](/design-style/optimizing-design-for-3d-printing/filaments.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
