FAQ
Metals are stronger, more durable, and machinable but costly. Plastics are lighter, cheaper, easier to form but less strong. Metals suit high-stress structural parts. Plastics work for complex shapes, low-stress parts.
CNC: Al 6061/7075, brass, copper, stainless, acetal. 3D print: ABS, PEEK, Ultem. Laser cut: Al, stainless, acrylic. Sheet metal: Al, stainless. Pick for properties and ease of processing.
OnlineMetals.com offers ABS, PLA, PETG, Nylon, and Polycarbonate. ABS is strong and heat resistant. PLA is biodegradable and easy to print. PETG combines PLA's ease with ABS's strength. Nylon is flexible and abrasion resistant. Polycarbonate is a high-performance choice for challenging applications. HDT = thermal resistance. Key for picking suitable materials.
Consider properties, machinability, cost, environment, aesthetics. Al = light, corrosion-resistant. Steel = strong, cheap. Stainless = corrosion-resistant. Brass/copper = conductive. ABS = machinable, versatile. Acrylic = clear. Delrin = stable. HDPE = cheap. Nylon = strong. PC = impact-resistant. UHMW = wear-resistant.
