In an era where additive manufacturing pushes boundaries, a remarkable story unfolds from a home garage, echoing the ambitious spirit of DIY innovation. While automotive giants explore 3D printing for concept cars, physicist Sterling Backus and his son have taken the technology into their own hands, embarking on an extraordinary project: 3D printing a full-sized Lamborghini Aventador replica. This isn’t just about building a car; it’s a compelling demonstration of what’s achievable with accessible 3D printing technology and a powerful father-son collaboration.

The Vision of a 3D Printed Supercar
The intersection of automobiles and 3D printing is rapidly evolving. Although complete, mass-produced cars made entirely with 3D printing are still on the horizon, the integration of 3D printed components in vehicles is increasing. This project by Sterling Backus showcases the disruptive potential of additive manufacturing, taking it from industrial applications to a personal, passion-driven endeavor. Driven by a desire to inspire his son about the capabilities of technology, Backus set out to 3D print a Lamborghini, leveraging readily available desktop 3D printers. This initiative highlights the accessibility of advanced manufacturing techniques and their capacity to realize seemingly impossible dreams, like creating a supercar in your own garage.
From Idea to 3D Printed Reality: The Process
Sterling Backus wasn’t new to the world of additive manufacturing. With prior experience using Fused Deposition Modeling (FDM) printers, he possessed the foundational knowledge to tackle this ambitious build. For the Lamborghini project, he utilized a combination of consumer-grade machines: CR-10S, CR-105S, and QIDI Xpro. The sheer scale of the project is evident in the consumption of 220 spools of thermoplastic filaments to construct the car’s body. For the primary body panels, PLA (Polylactic Acid) was chosen for its dimensional stability. ASA (Acrylonitrile Styrene Acrylate) and ABS (Acrylonitrile Butadiene Styrene) filaments were employed for components like rear light housings and headlights, requiring different mechanical properties. For interior parts demanding higher strength, carbon fiber-filled nylon was selected, demonstrating a strategic approach to material selection based on functional requirements.

The journey wasn’t without its challenges. Approximately 50 spools of filament were dedicated to tests and overcoming printing failures, underlining the iterative nature of 3D printing and the learning curve involved, even for experienced users. This highlights the importance of experimentation and perseverance in achieving successful 3D prints, especially in a project of this magnitude.
Beyond Additive Manufacturing: Combining Techniques
While 3D printing formed the core of the Lamborghini construction, Sterling and his son intelligently integrated other manufacturing processes to enhance the car’s structural integrity and aesthetic appeal. CNC (Computer Numerical Control) machining, waterjet cutting, vacuum infusion, and carbon fiber encapsulation were utilized in conjunction with 3D printing. Backus explained their rationale: “We decided to use advanced technologies to build the car. However, we wanted to use low cost options. This led us to researching different techniques of automobile construction. After choosing to use 3D printing for most of the car body, we needed solidity. Very few choices of heat stress resistant materials were compatible with our 3D printers; so we turned to encapsulation of 3D printed parts with carbon fiber.” This hybrid approach demonstrates a practical and resourceful methodology, combining the strengths of different manufacturing techniques to overcome limitations and achieve the desired outcome for their 3d Print Car project.

An Inspiration for STEM and Accessible Innovation
Sterling Backus’s ambition extends beyond simply building a 3D printed Lamborghini. He envisions the project as a powerful educational tool, aiming to inspire students in STEM fields. By showcasing this large-format 3D printing project at local schools, he hopes to ignite interest in science, technology, engineering, art, and mathematics among children. What better way to capture the imagination of young minds than with a real-life, partially 3D printed Lamborghini?
The project, initiated just over a year prior, involved daily dedication from the father and son duo, investing at least an hour each day. The total investment of $20,000 is remarkably low, especially when contrasted with the price tag of a commercially available Lamborghini Aventador, starting at over $300,000. This cost-effectiveness underscores the potential of 3D printing to democratize access to complex creations and reduce manufacturing costs. While Backus clarifies he has no intention of selling the car or competing with Lamborghini, his Facebook page documents the entire journey, offering a transparent and inspiring look into this DIY 3D print car endeavor.

The 3D printed Lamborghini project serves as a compelling testament to the evolving capabilities of 3D printing and its growing accessibility. It moves beyond novelty, demonstrating the potential for home-based, large-scale projects and inspiring a new generation to explore the boundaries of technology and innovation in creating their own 3D print cars and beyond.
