Materials
PLA (Polylactic acid)
PLA is the most commonly 3D printed material on the market. PLA comes in various colors and can be used for most applications. However due to it's low glass transition temperature (122 °F - 176 °F) it is not suitable for high temperature applications. PLA is also not UV resistant, long exposure to sunlight will degrade this material.
PETG (Polyethylene terephthalate glycol)
PETG is also one of the more commonly used filaments for 3D printing. However, PETG is a stronger material than PLA while also being resistant to high temperatures (185 °F, glass transition temperature), chemical solvents, UV exposure, and water.
Carbon Fiber reinforced Nylon
Carbon fiber reinforced nylon is one of the various types of carbon fiber reinforced plastics available on the market. These materials are extremely strong and lightweight. This type of material is commonly used in instances where strength-to-weight ratio and stiffness are primary factors of the design. While boasting exceptional material characteristics carbon fiber reinforced nylon and similar CF reinforced plastics come at a cost. These filament types are priced 2x-3x higher than their PLA and PTEG counterparts. Printing CF reinforced filament also requires an upgraded 3D printer in order to withstand the heat and abrasiveness of extruding these types of filaments.
