Aston Martin fan uses 3D printer to build DB4 replica

New Zealander Ivan Sentch had long-dreamed of owning a 1961 series II Aston Martin DB4, but with the stylish motor costing at the very least hundreds of thousands of dollars, he knew it was unlikely to ever happen. And then along came 3D printing.

Since December last year, the Auckland resident has been busy building a replica of the classic car bit by bit, and we mean bit by bit. You see, his Solidoodle desktop 3D printer isn’t big enough to print off large objects in one go, so the computer programmer is printing off several thousand sections – just 105mm x 105mm in size – that he then glues into place on a wooden frame. Sentch says that he’s currently about 72 percent of the way toward creating a plug from which he’ll then take a mold using fiberglass.

“I should point out that is just the printing; there will be endless months of work once it’s all assembled before I can take a mold – applying auto filler, sanding, repeat until it’s all true then sanding from 400 to 600 to 1000 grit sand paper until it has a glassy finish then applying mold prep and sanding with 1000 again,” Sentch explained in a Q&A post on Solidoodle’s blog.

The vehicle’s mechanical parts – he’s using a 1993 Nissan Skyline GTS for those – and interior also need to be added.

Remarkably, Sentch says that before embarking on the project, he had no experience of 3D printing, though his knowledge of CAD – he’s using a TurboSquid CAD rendering of the car for his project – is of course proving invaluable in the process.

According to Sentch, the project has been on his mind for the last six years, but starting a family forced him to put it on the back burner until earlier this year.

“The printing itself isn’t very time-consuming – click a few buttons to kick one off before I go to work and another one off before I go to bed – and preparing the next prints only takes a couple of hours a week,” Sentch said. “It’s just really the sanding of the printed parts before I glue them together that is time-consuming – and dreadfully boring.”

As for why the Aston Martin fan went for the DB4 over the pricier DB4 GT Zagato or James Bond’s DB5 model, Sentch explains: “I like old cars but most of the ones I like were just 2-seaters, and now with the kids….I went with an old Aston Martin (2+2 seats) because they’re just very, very cool, and a DB4 because I just like the look of it more.”

Mercedes-Benz G580 first drive: old-school off-roader goes electric
2025 Mercedes-Benz G580 from three quarter view.

American car buyers mostly know Mercedes-Benz as a luxury brand. But for decades, the automaker has also produced the tough, rugged G-Class (also known as the Geländewagen or G-Wagen), an SUV not afraid to get its leather upholstery muddy. And now, this iconic Mercedes is going electric.

The 2025 Mercedes-Benz G580 with EQ Technology — the final name of the SUV previously known as the EQG — isn’t the first electric off-roader. The Rivian R1S and R1T and GMC Hummer EV have proven that electric powertrains and off-roading are a great combination. But the electric G-Wagen is different because it’s based on an internal-combustion model — and a very traditional one at that.

Honda believes hydrogen semi trucks will make the case for fuel cells
Honda hydrogen fuel-cell semi truck.

Honda remains committed to hydrogen fuel-cell vehicles, but the market for those vehicles remains limited. So Honda is looking at other uses for fuel cells -- including commercial trucks.

To show how that could work, Honda converted a semi truck to fuel-cell power, replacing its diesel engine with three fuel-cell modules. Together, the three modules produce a combined 321 horsepower, and can propel the truck to a top speed of 70 mph. There's enough onboard hydrogen storage capacity for a 400-mile range with a full load, Honda claims.

Mercedes-Benz G580 vs Rivian R2: Is the much cheaper Rivian actually better?
2025 Mercedes-Benz G580 from three quarter view.

Mercedes-Benz has finally taken the wraps off of the new "Mercedes-Benz G580 with EQ Technology." Yeah, it's a mouthful, but it's basically a new electric G-Wagon. It looks a lot like the G-Wagon you know and love, but with an electric powertrain and a battery. It's not the only electric SUV out there, however, and there are some great ones -- like the Rivian R2.

Both the Mercedes G580 and the Rivian R2 have a lot going for them, but they also approach the electric SUV slightly differently. Is one better than the other? I put the two head-to-head to find out.

The approach that the two vehicles take to design is quite different -- and you might like one better than the other.
