With the auto parts market experiencing an acute shortage in many functions, car enthusiasts are turning their attention to the so-called 3D printing technology. With its help you
Printing is an expensive operation: the minimum price for one part starts from 5,000 rubles. It all depends on the material and size of the product. Usually such money is taken for a small spare part made of plastic or silicone.
Now let’s explain what the cost consists of. To print a part of the so-called ABS plastic you need a 3D printer with ABS filament. This is quite an expensive device. But before you start, you need the source, that is, what you want to print. For example, a decorative bumper air intake that has split in an accident.
First, the masters will scan the part and translate it into a full 3D model. Then the last one is made final, because the part is broken, but a whole is needed. Only then can you start printing. Then the received part is processed, painted if necessary and handed over to the customer. The easiest way is to print plastic wheel covers in this way. This makes the car more attractive in appearance and gives a touch of exclusivity.
It makes sense to print a rare small detail. A kind of rubber door seal. On some machines, these plastic retainers often break the locking tabs. It is difficult to find such fasteners when disassembling, so only 3D printing will help. You can also print individual elements for the block headlight. Since optics are not cheap now, it will be economically feasible to restore the headlight.
But with large details it is more difficult. Making a car bumper, for example, just doesn’t work. It will have to be printed in parts, because there are no such large 3D printers. Then process so that the parts come into perfect contact with each other. In addition, the material must be additionally reinforced, because the plastic is quite fragile.
Don’t forget time and money. A factory bumper therefore weighs about 10 kg and it takes about 20 kg of plastic to print it. All this is printed continuously for 4 months, so the electricity costs will be significant. Then, as we wrote, glue, fit, paint, install. The price will turn out to be cosmic for the owner of a very expensive and rare car, for example, a Ferrari sports car.
Continue. Now there are technologies that allow you to print not only plastic parts, but even metal ones, from aluminum, stainless steel, titanium, and so on. This technology comes from the usual sintering of materials used in powder metallurgy. But now it has become more perfect.
The main thing here is a modern metal printing 3D printer. Allows you to choose an individual configuration for printing with a specific metal powder. And this powder is melted by a laser.
However, it should be remembered that the rigidity of the printed part is lower than that of the molded part. Therefore, we do not recommend the use of such spare parts, for example in an engine or suspension. For example, it is not possible to print the entire crankshaft. This is a very big detail, which means it has to be done in parts. And the connection of these parts will lead to errors, and it will be difficult to balance such a crankshaft. If you take the chance and install it in the engine, no one can guarantee how long the spare part will last and how the engine will run. High temperatures will most likely just cause it to fall apart and the power supply will die.
Replacing the timing mechanism rollers with printed copies may also destroy them. Then the revision is guaranteed. As for the chassis, here too it will not be possible to make a large wishbone from one piece of metal. And if you cut it into pieces, it just won’t withstand the blow and will split.
That is, we repeat that 3D printing is suitable for the manufacture of fastening elements, for example, a bumper, or decorative interior elements. Therefore, do not blindly rely on new technologies. First estimate the repair costs. It may be more economical to order parts and wait three or four weeks, rather than paying hefty money to manufacture them through 3D printing.
