MATERIAL SPECS
Learn why and which materials we use
Engineering-grade materials for motorcycle parts are essential because there is no one-size-fits-all solution in 3D printing. Every component requires a unique set of capabilities, whether it’s enduring constant UV exposure on a side cover, chemical stress from fuel, or the need for high-heat near the cylinder head. That’s why we exclusively use the same industrial polymers trusted in the automotive and aerospace industries.
At R3print Moto, we assess the specific environment of every part before production. By matching the mechanical needs of the part with the strenghts and weaknessess of our engineering-grade materials, we ensure our 3d printed classic motorcycle parts don’t just fit. They provide a permanent solution for your restoration.
PPS
Extreme performance for the engine bay. These high-heat 3D printed parts offer the chemical resistance necessary to survive constant exposure to fuel, oil, and intense operating temperatures.
PPA
High-strength, heat-resistant polymer with metal-like strength and excellent impact resistance. Built for structural components exposed to fuel, oil and mechanical stress.
Nylon
The choice for Stress & Abrasion. For structural mounts, sliding chain guards, or brackets subject to intense vibration, we use carbon-fiber reinforced Nylon to handle mechanical load and constant wear.
TPU
The solution for unobtainable motorcycle gaskets. We recreate 3D printed rubber seals and vibration dampeners that outperform original parts, providing modern flexibility for classic restorations.
ASA
The standard for 3D printed motorcycle fairings and plastics. Engineered for maximum UV stability and weather resistance, ASA is the ideal replacement for brittle factory plastics that need to survive the sun.
Frequently asked questions
Q: Why don't you use standard 3D printing filaments?
A: Hobby-grade materials like PLA or PETG cannot be guaranteed to withstand the demands of a motorcycle. We exclusively use industrial polymers to ensure longevity and safety.
Q: Can these engineering-grade parts be painted?
A: Yes. Our ASA, Nylon and PPS parts are specifically selected for their ability to be finished to an OEM standard, allowing for a seamless look on any classic bike.
Q: How do I know which material my part needs?
A: That is part of the re-engineering process. We evaluate the original part’s placement and function to select the material that offers the best performance. However if you want your part made from another material, please reach out to us.
Q: How do these materials handle vibration?
A: Classic motorcycles are high-vibration environments. While hobbyist plastics are prone to stress-cracking, we utilize Carbon-Fiber reinforced Nylon and TPU specifically for their energy absorption and fatigue resistance. This ensures that brackets and mounts won’t snap under the harmonic stress of a running engine.
Q: Will these parts warp if thebike is left in the sun or a hot garage?
A: No. We select materials with a high Heat Deflection Temperature (HDT). For example, our ASA and PPS materials are stable at temperatures far exceeding what a bike faces in direct sunlight or storage, preventing the sagging or warping common with lower-grade 3D prints.
Q: Are the materials resistant to cleaners and degreasers?
A: Yes. Maintenance is part of owning a classic. Our PPS and Nylon specs are specifically tested for resistance to common workshop chemicals, including chain lube, degreasers, and fuel, so you can clean your bike without worrying about damaging the R3-engineered components.
