3D Printing a 1952 Porsche 356 Engine in 1:4 Scale

While a 356’s flat-four powerplant is light and compact, it is far from a desk-top piece. Giuseppe Guerini has approached this problem with an all-new 3D model of an early 356 engine, resulting in a resin model printed in 1:4 scale. Though the resin engine cannot run, the level of detail is impressive. The final build includes 250 pieces cast in three different resins. How long until we see this in 1:1 scale built of aluminum or magnesium?

Guerini built the digital model in Rhino and Meshmixer, and used the Formlabs Form 2 to 3D print the resin parts. Much of the model iss made of clear resin, allowing screws to be more easily threaded, and simplifying finishing work. Soft parts, like the belts and hoses, are made of a 3D printed soft resin. The print work is estimated at some 45 hours, and assembly around another four hours.

Additional photos of the build can be seen here and here. The model is available for sale on Creatr, though no prices are listed.
