# 3D-Printed Car Transmissions An Engineer Created This Working 5-Speed Transmission for a Toyota By Jana Pijak | Published 2015-03-17 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/3dprinted-car-transmission References: [3dprint](http://3dprint.com/50265/3d-printed-toyota-transmission/) This 3D-printed car transmission was designed to fit a [Toyota](https://www.trendhunter.com/trends/lego-vehicle) 22RE engine. The fully functional model is the work of mechanical engineer Eric Harrell of Santa Cruz, California. The 5-speed 3d-printed car transmission is Harrell's second attempt at a working car part and follows his fully functional Toyota engine project. The engine is was also made using [additive manufacturing techniques](https://www.trendhunter.com/trends/fibreseeker-3) and has been combined with its accompanying transmission. The engineer's combined car part project was created using complex [3D-printing practices](https://www.trendhunter.com/trends/heygears1) and has inspired 8 other inventors to try their hand at their very own version of it. This inspiring project illustrates how far additive manufacturing has come and suggests that the future of car parts will be one fulled by 3D-printing technology. ## Trend Insights (Trend Hunter) - Score: 4.7/10 - Popularity: 80% | Activity: 54% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### What Makes This Trend Stand Out - **Additive Manufacturing:** The 3D-printed transmission showcases the potential of additive manufacturing in producing functional car parts. - **Personalized Automotive Manufacturing:** The ability to 3D-print car parts opens up opportunities for personalized manufacturing, where customers can request customized transmission designs. - **Technological Advancements in Automotive Industry:** The use of 3D-printing technology in car part production demonstrates the continuous technological advancements in the automotive industry. ### Sectors Adopting This - **Automotive Manufacturing:** Automotive manufacturers can leverage 3D-printing technology to revolutionize their production processes and offer innovative car parts. - **Additive Manufacturing:** The 3D-printing industry can capitalize on the demand for functional 3D-printed car parts, such as transmissions. - **Engineering Services:** Engineering service providers can explore opportunities in designing and producing 3D-printed car parts for various automotive applications. ## Related on Trend Hunter - [E-Bike Transmission Systems](https://www.trendhunter.com/trends/automatic-bike-transmission.md) - [3D-Printed Motorsports Components](https://www.trendhunter.com/trends/mclaren-racing-x-stratasys.md) - [3D-Printed Car Storage Inserts](https://www.trendhunter.com/trends/peugeot.md) - [3D-Printed Hypercar Components](https://www.trendhunter.com/trends/3dprinteros.md) - [3D-Printed Ball Machines](https://www.trendhunter.com/trends/fraens.md) - [3D-Printed Workshop Wrenches](https://www.trendhunter.com/trends/workshop-wrench.md) - [3D-Printed Auto Accessories](https://www.trendhunter.com/trends/fits.md) - [Ultra-Fast Manual Transmission Vehicles](https://www.trendhunter.com/trends/venom-f5m.md) - [Range-Extending eBike Transmissions](https://www.trendhunter.com/trends/orbit-drive.md)
