Sebastiaan Pot<\/a>\u00a0lives in Assen, in the northeast Netherlands. Last year Sebastiaan introduced himself in the Newcomers Lounge on the Shapeways forums<\/a>\u00a0and explained that he makes bigger scale model cars, up to the very rare 1:4. Since then he\u2019s been working quietly on a formidable project: a fully 3D printed 1:4 scale AC Cobra<\/a><\/strong>. Right now it’s a non-motorized scale model, but it can be transformed into an RC car.<\/p>\n

The history of the AC Cobra is pretty unique among sports cars:<\/p>\n

In September 1961, American automotive designer\u00a0Carroll Shelby<\/a>\u00a0wrote to [British car manufacturer] AC asking if they would build him a car modified to accept a V8 engine. AC agreed [to the modifications to its roadster], provided a suitable engine could be found. Shelby went to Chevrolet to see if they would provide him with engines, but not wanting to add competition to the Corvette, they said no. However,\u00a0Ford<\/a>\u00a0wanted a car that could compete with the Corvette, and they happened to have a brand new engine which could be used in this endeavor: the Windsor 221 in\u00b3 (3.6 L) engine \u2013 a new lightweight, thin-wall cast small-block V8. Ford provided Shelby with two engines. – Wikipedia<\/a><\/p><\/blockquote>\n

And the AC Cobra was born! The cars were only manufactured for five years<\/a>, helping their legend to grow far beyond their availability. Thankfully, Sebastiaan’s love for the vintage roadster led him to create something truly extraordinary.<\/p>\n

You don’t get to see a 1:4 scale car very often, so I drove the two-and-a-half hours from Eindhoven to Assen, from one end of the country to the other, to see what Sebastiaan had spent the past year making.<\/p>\n

When I got there, I was blown away. His AC Cobra is almost a meter long \u2014 and it\u2019s a masterpiece:<\/p>\n

\"scale<\/p>\n

Sebastiaan has a gift for drawing: Show him the front, side and top views of a car and he \u201cunderstands the lines\u201d and can effortlessly draw the exterior on his computer.\u00a0Interiors take him a bit longer, but he can 3D model those too by simply looking at a handful of photographs.<\/p>\n

Sebastiaan spoke to me before about his gift for drawing as if it\u2019s nothing special, but based on my own forays into 3D design and what I hear from other community members, he\u2019s awfully modest.\u00a0Next time I visit him we will focus more on the design process, and we’ll bring you the full story of 3D printing a car on this scale \u2014 but this time, I was simply too amazed by this car to do anything but stare:<\/p>\n

Check out the stunning interiors:<\/p>\n

The seats are 3D printed, then finished in leather. And yes, the buckles actually work.<\/p>\n

In some cases, for instance the gears in the dashboard, Sebastiaan 3D printed molds, then made the pieces out of aluminum. The steering wheel is made of wood \u2014 and you can even remove the key from the ignition.<\/p>\n

\"scale<\/p>\n

Sebastiaan printed the radiator in Shapeways Frosted Ultra Detail plastic<\/a>. The headlights are made from our Transparent Detail Acrylic<\/a>, then treated in a clear gloss. The blinkers get a coat of orange acrylic paint.<\/p>\n

The wheels are made of Elasto Plastic<\/a>. Sebastiaan found it particularly challenging to get the the right jet-black look.<\/p>\n

On the picture below, the two left hubcaps on the table are 3D printed Sterling Silver<\/a> and the other two parts in the foreground are Rhodium Plated Brass<\/a>. Which do you think look more realistic?<\/p>\n

The exterior is made from\u00a0Shapeways Strong & Flexible Plastic<\/a>. At 99 cm long, it needed to be printed in parts. With all the layers of paint, however, there are no visible seams. In the Facebook Live video below you see us taking a closer look at the overlap of parts at 5:00.<\/p>\n

You can learn more about the AC Cobra from this Facebook Live stream from my visit to Sebastiaan\u2019s workshop and home in Assen. We start with a reveal and then take a closer look to the rich details of this scale model:<\/p>\n
