How To 3D Print Replacement Car Parts [2022 Guide]
If you're looking to create your own car parts, you can do so with ease. Here is a guide on how to 3D print replacement car parts very cheap.
By Justin Evans
As 3D printing technology grows more popular, hobbyists and automotive industry leaders alike are starting to 3D print car parts as an alternative to expensive repairs and manufacturing.
This may seem unbelievable to people outside of the 3D printing space, but it is true. 3D printers can create all kinds of car parts, and they work just as well as traditionally manufactured parts.
There are plenty of reasons why people do this. They may want to personalize their car, make their car lighter, or just replace a part quickly without needing to pay an excessive amount for it.
For people who want to get into it, it is a lot easier than it looks.

What Kind of Parts Can You Make With 3D Printers?
There are several types of parts that you can use 3D printing to manufacture:
- Cosmetic customization (rear-view mirrors, cup holders, custom frames)
- Small parts (lids, valves, specialized parts)
- Larger parts (grills, dashboards)
While you can make powerful parts with 3D printing (like with carbon fiber), it is not recommended for making internal car parts. These parts must deal with excessive heat or pressure and require a specialized manufacturing process.
So long as you keep the part, your intended material, and what that part is used for in mind, the sky is the limit as far as what you can create.
What Kinds of 3D Printers Are Best for 3D Printing Car Parts?
When 3D printing car parts, the ideal printer can vary depending on what you are trying to print.
For most things, an inexpensive basic printer is fine. Plenty of car parts are small and simple and should not need a heavy-duty machine to do the lifting.
If you plan on printing more complex parts or want intricate engravings on your customized parts, you may want to use a higher-end model that can handle that.
What Materials Should You Use?
There are plenty of materials you can use to 3D print your car parts, but the rule of thumb is they should be durable, lightweight, and flexible.
A few standout materials are:
- TPU (shock-absorbent, flexible, and durable)
- Polypropylene (great for airflow and fluid systems)
- Nylon PA11 (great if you are worried about sustainability)
- Polyamide 6 (heat resistant)
What material you use depends entirely on what part you want to make, so always do your due diligence and research what materials work best for each part before you start printing.
How Do You Go About 3D Printing Car Parts?
3D printing car parts seems complex, but when you get down to it, it is a simple process that only requires a few steps.
Make or Find a Scale Model
This is the most important step of the entire process.
A high-quality 3D printed car part relies on using the proper material and creating it from a good model.
You can set up your scale model in one of two ways. You can make the model yourself using a 3D modeler or find a model online. If you are not confident in your 3D modeling skills, it may be best to find an online model rather than make it yourself.
Many websites offer 3D models for parts that you can download and use with your 3D printer. Make sure the model is from a reputable source for the best results.
Pick Your Material
After picking out your model, the next step is to pick what material you want to use. This will depend entirely on what part you are making and your specific needs.
Remember, materials are not a one-size-fits-all solution. Make sure the material you choose matches your part’s use (heat resistance or flexibility, for example). If you make a part with the wrong material and install it, it can break or damage your car.
Also, keep in mind that just because you can theoretically make engine parts with 3D printing does not mean that you should.
Print the Part
After you have your model and material, it is time to make your part. Make sure the parameters are set the way you want them and double-check everything before printing. Follow the instructions based on your specific printer.
Finishing Touches
Once your part is printed, it is time to add any finishing touches. This is when you paint any small details, like numbers on a knob, or coat the part in another material for a better finish.
You should also use this time to check over the part and make sure everything is up to standard. If there are any defects or issues with the part, you will need to start over.
Install the Part
After printing the part, it is time to install it. This is simple for a part like a cup holder or knob — just pop it in and see if it fits.
If you 3D printed a part like a grill or a dashboard, try going on a test drive first and see how it holds up under a stress test. If it looks like it is not holding up well, it’s time to go back to the drawing board.
What if You Don’t Want to Do It Yourself?
Sometimes 3D printing car parts is not feasible for everyone. A person may want to 3D print a part, but they do not have access to a printer or are not confident in their 3D modeling skills.
In this case, you may want to consider hiring a business that specializes in 3D printing car parts. Be sure to check the business’ rates, selection, and reviews before committing.
Conclusion
3D printing car parts is an easy way to customize and repair your car without breaking the bank. With the right model, materials, and plenty of patience, 3D printing your own parts is a reliable way to take care of your car and make it your own.
There are no limits to what can be done with 3D printing, whether you do it yourself or hire someone else to make the parts for you.

5 ways 3D printing is changing the automotive industry / Sudo Null IT News
You can't buy a fully 3D printed car in a car dealership yet, but additive technologies have been used in car design for many years.
Every year, especially in recent years, 3D printing is taking an increasingly important place at all stages of production. This is evidenced by the rapid growth of 3D printing market share in automotive manufacturing, which is projected to reach $2.5 billion by 2023.
For example, luxury car companies including Bentley, Porsche, BMW and Ferrari are using 3D printing to create custom car interior parts. GM, Volvo, Ford are using 3D printing to produce tooling to save money, improve designs and reduce delivery times. 3dprinting.com If the first 3D printers cost about $20,000, now you can find 3D equipment for $100. Now companies can, with the help of additive technologies, produce the necessary components directly at their own enterprises and not depend on suppliers.
With new materials, 3D printers can print high-precision, functional end parts. Additive technologies facilitate the production of custom products and increase productivity.
But this is only the beginning of the journey.
Here are five key ways 3D printing is driving innovation in the automotive industry, from car design to production. Plus one bonus.
1. Changing the prototyping process
It was with the manufacture of prototypes that the use of 3D printers in the automotive industry began. 3D printed prototypes took much less time than traditional methods required.
Using Raise3D 3D printers and ideaMaker software, Crazy Grandpa Garage was able to automate the process of creating custom car parts. Production costs have been reduced by 50%, design reliability has improved significantly, and lead time has been reduced by 83%. The parts now come out very well fitted to the car.

Using 3D printing, car designers can quickly prototype individual parts or assemblies, from interior detail to dashboard, or even full-size car models. Thanks to 3D prototyping, the initial idea quickly turns into a physical embodiment of the concept - a conceptual model.
The concept can then be developed into full-featured, high-fidelity prototypes, and after several validation steps, mass production begins. For the automotive industry, getting through these steps quickly is vital, and the entire downtime of an automobile production line in just an hour is very costly for the company.
For example, the assembly plant of the US car manufacturer General Motors claims to have saved more than $300,000 by purchasing a 3D printer in 2016.

Traditional prototyping was time-consuming and costly, in part because the product went through more iterations. With 3D printing, you can create high-quality prototypes in one day and at a much lower cost.
More examples.

For example, General Motors has partnered with Autodesk to produce low cost, lightweight automotive parts using 3D printers. Tools, fixtures and fittings can now be produced at a fraction of the cost, according to Autodesk. For example, a 3D printed tool used to align engine and transmission ID numbers costs less than $3 at General Motors. A traditionally produced instrument will cost $3,000. In addition, downtime due to faulty tools can be significantly reduced as new tools are produced in-house.
2. Creation of non-standard and complex parts

In Europe, the BMW MINI brand also uses 3D printing to create personalized car parts. Since the beginning of 2018, MINI customers have been able to personalize various trim elements such as the instrument panel, LED treadplates and illuminated bumpers, as well as choose from different colors and textures. These parts are then 3D printed using a range of technologies from DLS Carbon to SLS.

Large companies are merging 3D printing technologies with traditional manufacturing methods.
Volkswagen has recreated its iconic 1962 Microbus by replacing the petrol engine with a 120 hp electric one. The Type 20 concept electric minivan has received many improvements using 3D printed parts. These improvements include cast aluminum wheels. Even the wheel hubcaps, while looking like stamped steel, are actually printed on a Formlabs SLA 3D printer, then electroplated and polished.

3D printing has also made it possible to create parts that could not be made in any other way.
Bugatti's monobloc brake caliper is a prime example. For some components, Bugatti would have preferred titanium due to its high performance, but processing this metal with traditional methods is expensive and difficult. 3D printing has allowed Bugatti to produce a titanium alloy brake caliper. Due to the thin walls, the caliper turned out to be very light - almost two times lighter than forged aluminum. At the same time, the strength of the 3D-printed monoblock is superior to that of aluminum. The 3D printed titanium monoblock has a tensile strength of 1250 N/mm2. This means that a force of just over 125 kg will be applied per square millimeter of this titanium alloy without tearing the material. The new titanium caliper is 41 cm long, 21 cm wide and 13.6 cm high and weighs only 2.9kg compared to currently used aluminum, which weighs 4.9 kg.

3. Tool making
Various devices help to facilitate and speed up the production and assembly processes, improve the safety of workers. Automotive factories and component suppliers use a large number of non-standard tooling that is specifically designed and optimized for end use. As a result, a lot of non-standard equipment and tools are made, which increases production costs.

Delegating custom tooling and fixtures to service providers who machine parts from solid metal or plastic stock can delay production by weeks.
For example, the development and prototype of a commutator motor using traditional manufacturing methods can take up to four months and cost about half a million dollars.
Thanks to 3D printing, Ford was able to develop several variants in just 4 days and 99.4% cheaper - only $3,000.

Additive technologies allow you to complete the task in a few hours and significantly reduce costs compared to ordering from a third-party enterprise. Since increasing the complexity of a 3D printed model does not incur additional costs, products can be better optimized for their application. New elastic materials for 3D printing in many cases allow you to print plastic parts instead of metal or create prototypes on a 3D printer to test the tool before using it in production
Gradually, the production of 3D printed accessories and tools is becoming one of the largest applications of additive technologies.

For example, Pankl Racing Systems uses a stack of multiple Formlabs SLA 3D printers to make critical manufacturing tools.
The multi-stage production of parts for transmissions on automatic lathes requires a series of fixtures and tools designed for each specific part.
With the help of 3D printing, Pankl's engineers have reduced the production time for the aids by 90%, from 2-3 weeks to around 20 hours. Costs were also reduced by 80-90%, saving $150,000.
The transition to 3D printing has enabled Volkswagen Autoeuropa to cut tooling development costs by 91% and cut tooling times by 95%.
4. Troubleshooting spare parts
Spare parts have always been a problem for the automotive industry. The demand for them is either there or not, so the production of spare parts is not economically viable, and the storage of pre-fabricated replacement components is also costly. But if there are no repair parts available, difficulties arise and the main product becomes less valuable.
3D printing could solve the problem of parts in the automotive industry in many ways.
The main factors are printed materials, which can match the characteristics of traditional materials used in parts and be cost-effective. There are prerequisites for this.
Using computer-aided design, drawings of all parts can be stored digitally, so there is no need to store the parts themselves. The parts needed by the client can be printed on a 3D printer right in the workshop.
Even obsolete parts whose blueprints have not survived can in principle be recreated by making a 3D scan of existing parts of this type and applying reverse engineering (reverse engineering). You can read more about this on our blog. Old projects can take on new life. There are many lovers of vintage cars, with the help of 3D printing it would be possible to create parts for them.

5. Production of standard parts
As 3D printers and materials for 3D printing become more affordable, a gradual transition to the production of mass-produced automotive parts using additive technologies is possible.
3D printing makes it possible to combine components into a single whole. Let's say there is a mechanism assembled from six or seven car parts that can be combined into one printed part. It will save time and assembly costs. With 3D printing, it is also possible to reduce the weight of the combined assembly, as a result, the car will use fuel more efficiently.
3D Systems has designed an advanced exhaust pipe for a sport bike. In the image below, you will see 20 sheet metal and hydroformed parts needed to assemble the original exhaust pipe. On the right is a monolithic exhaust pipe that does not require assembly, made using metal 3D printing.

The 3D printed tube was produced using Grade23 titanium in just 23 hours, compared to three weeks for traditional production. Design development time reduced from 6 weeks to 6 days. Additive manufacturing also eliminates the need for tooling, fixtures, multiple welding and multiple inspections.
Geometry optimization has reduced the amount of material needed for maximum productivity. All elements of the original exhaust pipe are incorporated into the new design and, when printed with a typical wall thickness of 0.5mm, the 3D printed exhaust pipe is about 25% lighter than the original one.
A wide range of 3D printing materials is starting to meet the requirements of various vehicle components. Since additive methods reduce costs compared to traditional methods (such as molding and injection molding), it makes a lot of sense from a production and financial point of view to further introduce 3D printing into the production of basic parts.
Volkswagen, one of the world's largest and most innovative car manufacturers, is using an HP Metal Jet 3D printer to produce high-performance functional parts with special design requirements, such as shift knobs and mirror mounts. Volkswagen's long-term plans to work with HP include accelerating the production of mass-customized parts such as key rings and exterior nameplates.

+1. 3D printed cars
While 3D-printed cars have yet to hit the market, there are some interesting designs and concepts that can suggest a possible direction for the automotive industry.
Light Cocoon . German engineering firm EDAG was clearly inspired by nature to create the 3D printed supporting structure of the Light Cocoon concept car. The frame resembles the veins of a tree leaf or its branch. Despite the fact that the design of the EDAG took less material than a conventional frame, all the strength requirements for structurally significant components are met. Outside, the case is covered with a lightweight and durable waterproof fabric.

Strati . The American company Local Motors 3D printed and assembled the Strati electric car right at the exhibition stand, in just 44 hours. Most of the components were printed - the body, seats, interior parts. A car is made up of less than 50 assemblies, far fewer than the thousands of parts that go into a traditional car. The company intends to reduce the print time to 10 hours.

3D printing of prototype parts for cars and auto parts
3D printing of parts and auto parts one of the most common applications for 3D printing technology. Its effectiveness is confirmed at least by the fact that almost all global automotive brands are already opening additive centers for the production of components for their car models.
In our country, this industry is being developed by many enthusiasts: from owners of desktop 3D printers to specialized companies. The use of 3D printing in the automotive industry is a common practice that has proven to be effective and promising.
Benefits of 3D printing in the automotive industry
3D printing technology is widely used in the automotive industry. Developers and designers using additive manufacturing have the ability to quickly and cheaply create prototype parts for car concepts, test the assembly and performance of various components with the ability to make adjustments at any stage. For service centers, 3D printing of spare parts allows you to save on the purchase of parts and reduce their waiting time. The printing of spare parts on a 3D printer for modeling among collectors is also common. Printing parts on a 3D printer brings a lot of advantages.
Advantages of 3D printing in the automotive industry:
- 3D printer for auto parts allows you to create any component from any of the elements.
This makes it possible to manufacture a part to replace a broken one: be it one of the gears in the gearbox or a retainer for the rear-view mirror; - A variety of consumables allows you to create spare parts with different properties: elastic, soft, hard, and so on. If ABS plastic is used as the basis, the main quality will be low cost and conformity of products to linear dimensions. If it is polyamide, then the key advantage will be hardness and resistance to friction;
- you can introduce unique developments of limited edition technology - this is valuable both for car developers and for people who modernize and tune their car models;
- high speed of creation - 3D printing of auto parts on average takes much less time compared to traditional production methods;
- Available post-processing: primer and filler application, sanding, painting, varnishing, polishing;
- low cost - a component printed in a single copy is an order of magnitude cheaper than an industrial sample.
This is especially true for spare parts that are difficult or impossible to find in mass sales.
Auto tuning and 3D printing
Printing parts on a 3D printer is of particular value among connoisseurs of car tuning. The modernization process itself involves not only changing the appearance, but also improving the performance of the vehicle. For this, uniquely designed parts and components are used, often existing in a single copy. Previously, their development and production required large financial and time costs. Now it is enough just to develop a three-dimensional computer model, after which any suitable 3D printer will make it possible to produce both prototypes and functional parts with the desired characteristics.
What parts are usually ordered to be printed?
3D printing of car parts allows you to create both prototypes and products designed for long-term and efficient performance of certain functions in systems and mechanisms.
