Key Points:
- Alexander has developed a third-generation internal combustion engine with significant components 3D printed using common desktop FDM plastics like ASA and ABS.
- The engine includes 3D printed pumps for coolant and oil distribution, with engineering improvements to prevent fluid mixing seen in earlier versions.
- While much of the engine is plastic, critical parts such as a stainless steel sleeve in the engine block and a CNC-machined aluminum head are added for durability.
- Assembly requires additional hardware including bearings, belts, filters, and an off-the-shelf carburetor, indicating the engine is not entirely 3D printed but still a notable engineering achievement.
- This project highlights innovative use of accessible materials and desktop 3D printing technology to create functional internal combustion engines.
