Hello everyone! We are 3D Sets and we would like
to show you our project. We have a lineup of 3D-printed remote controlled off-road cars.They have plenty of great little features and they look just like the real thing. So, what we do is we
sell premium-quality 3D models for 3D printers. We wanted to offer models that will go
beyond the usual statues and flower pots and since we are both RC car enthusiasts,
it was pretty easy to decide what to do: let's make 3D-printed RC cars! We set out on
a journey towards our first model. It's a 4×4 off-road car which is printed using the Original
Prusa 3D printers. The only thing you need to buy is the motor, electronics and a bunch of screws.
The cars are rather large, so it will take you nearly two weeks of non-stop printing to produce
all the parts and you will need between two and a half and three kilograms of filament. We also fully
support parts with various colors, meaning that parts that should have the same color are already
grouped together on a single build plate.
Of course, there is a detailed step-by-step guide on how to
assemble the entire model. This is the overview of the model, here's a shopping list, which also
includes links to a recommended eshop. We also have a set of testing objects. By printing them, you can
tell whether your printer is calibrated correctly. In the end it's almost like LEGO. The assembly
process receives a lot of positive feedback from our customers and in case any inaccuracies or
some other issues with the assembly are reported we can easily update our Google Slides project
and all the customers see the update immediately. So here's our brand new Landy 4×4. Its
parts are spread across 30 build plates. Again, this means around 14 days of printing, give
or take. We understand that not everyone can be around the printer 24 hours a day, so it's not 14
days of non-stop printing. We also offer a wide range of accessories and custom parts, so anyone
can make them and modify their cars to achieve truly individual results.
So it's not just about
the color. You can choose to mount a hard top or leave the car without a roof, add plenty of
various little details. You can really have a lot of fun with the modifications. Plus, in case
anything breaks, you can easily print a replacement. The only thing we don't recommend printing are
the tires. Printing with flexible filaments may be tricky and the results are often not that
great.
Even if you don't want to spend money on the electronics, you can, of course, print
the cars and put them on a shelf in your office or living room. However, it's still a fully functional
off-road RC car, so we recommend to take it outside. We drove it across beaches, mud, we took it
to the mountains. Gravel, sand, grass… it can drive pretty much anywhere with ease. I
would like to add one important detail: our cars will always have added value compared
to models you can buy in a regular store. Replacement parts are a no-brainer
and you can keep on modifying the car to your heart's content. Everything is 3D-printed,
even the gears in the gearbox. We wanted to have as many 3D-printed parts as possible. Well, as long
as everything works the way it should.
We wanted to demonstrate what you can achieve with a 3D printer
nowadays. Not just produce flower pots and statues. We even considered a 3D-printed engine… well, that
was a bit too ambitious. Here you can see the axles which are fully 3D-printed we even have 3D-printed
ball joints, which is something many would consider impossible to make. We did it, though! We came up
with a fully functional solution that allows the parts to snap together.
There is one thing we
did not mention: there is no glue needed anywhere. Everything is held together by screws. So, the only
thing you need to repair your car is a screwdriver! Everything can be disassembled, replaced, upgraded…
the car will simply grow with you. To achieve all of this, we had to come up with a flexible
design. We are using Fusion 360 and cloud sharing. We are working with parametric models, so
it's easy to implement any changes without an exhausting manual tweaking process. I always
had a dream to start selling something digital online and worldwide – this was the perfect fit. It
took us around 1500 hours to design the first car. We had to learn a ton of things from scratch. We
made our own website, eshop, guides, everything. And I had to explain to my wife, whether we really
needed a second 3D printer – and of course we did.
That's really the gist of it. And the most
beautiful day was when we finally launched the eshop and orders started rolling in. The first one
was from Mexico, the next one from Indonesia. And we managed to reach our goal. We really hit
the global market. So, right now, we have our hands full with new products and there might be
even something more than just more off-road cars.
