KNOWLEDGE HUB
Preserving motorcycle legacy
Finding discontinued motorcycle parts shouldn’t be the end of your restoration or your motorcycle. We created this knowledge hub to show you how we bridge the gap between no longer available (NLA) original components and modern, 3D printed replacement parts.
Explore our technical resources to learn about our process: from selecting high-durability materials that outperform 40-year-old plastic, to our guides on achieving a factory-correct OEM finish.
Material Specs
Not all 3D prints are created equal. We select materials specifically to the demand of the part. From UV stability to heat resistance, we ensure your parts handle the daily realities of the road.
Printing Tech
Learn what can be 3D printed and how the process works. We explain the FDM methods used in-house and explore industrial SLA and SLS tech to help you understand how the replicas are made.
Digital Blueprints
Our library is a curated collection of community-vetted designs, each tested for accuracy and strength. Whether it’s open-sourced or re-engineered inhouse, if it’s in our archive, it’s ready to be 3D printed.
OEM Finish
A 3D print is just the beginning. From smoothing and painting to final assembly, we show you how to post-process our parts to achieve a factory look. Learn how to get a professional finish.
Restoration Stories
Every classic bike has a story, but a single broken part can end it. We document how re-engineering brings rare and ‘unobtainable’ components back to the road. See how modern technology keeps motorcycle history alive, one project at a time.
