Nylon-fiberglass blends also offer increased stability without compromising flexibility. This material combination is often used in the production of robust and durable bicycle components that have to withstand daily stresses.

Metal powders, especially aluminum and titanium, are also used in 3D printing. Aluminum is lightweight and offers good strength, making it well suited for manufacturing components such as handlebars, stems, and cranks. Titanium, on the other hand, is extremely strong and corrosion-resistant, making it an excellent choice for high-quality and durable bike frames. The use of metal powder makes it possible to print complex and detailed structures that would be difficult to achieve using traditional methods.

Polyethylene terephthalate glycol (PETG) is another widely used material in 3D printing. PETG combines the best properties of PLA and ABS, two of the most common 3D printing materials. It is strong, flexible and easy to print, making it ideal for making bicycle components and accessories. PETG is often used for mudguards, bottle cages and other accessories that require a certain degree of flexibility and durability.

Thermoplastic polyurethane (TPU) is known for its elasticity and durability. This material is often used for making flexible and shock-absorbing parts such as tires, grips and protective covers. TPU offers excellent resistance to wear and tear and is ideal for components that are subject to constant movement and stress.
