Print every part of the automotive process

Everything from a small piece of an automobile, to a prototype to the complete automobile can be designed with 3D printing.

Impact of 3D Printing in Automotive Industry

Since the past several years, car manufacturers have mostly employed 3D printing in the automobile sector to manufacture vehicle prototypes to test its design and fit. The first method for manufacturing components was selective laser sintering, also known as binder jetting. This enabled carmaker to build visually pleasing pieces, although they were fragile and therefore could not be utilized for long periods of time.

Recently however, more durable procedures for automotive 3D printing exist, such as fused filament fabrication (FFF), which may be utilized to produce not just prototypes but also final analysis components.

Traditionally, prototyping is by far the most popular use application for 3D printing in the automobile sector. Rapid prototyping has become generally compatible with 3D printing due to the substantially improved pace during which prototype can be performed using the technique, and the system has transformed the product development cycle.

Automotive manufacturers can use 3D printing to swiftly design a prototype of a physical item or assembly, such as a small interior piece, a console, or even a scale replica of a complete automobile. Companies may use rapid prototyping to transform ideas into credible demonstrations of ideas.

sales annually by 2024.” Since this industry is dominated by a few OEMs, entry hurdles are quite high.

The market for parts and accessories is distinct. There are several major and small-scale participants, and the rivalry is fierce. This market is expected to be worth roughly US$ 17 billion by the end of 2025.

Lastly, as per Machine Design, the automobile industry’s use of 3D printing components will reach $530 million by 2021.

Core Applications of 3D Printing in The Automotive Industry

Design and concept of communication

Fine precision, smooth, and precise 3D printed size replicas are frequently used in the automobile industry to illustrate new car designs and concepts. The explanation is straightforward: utilising CAD models by itself is insufficient for defining potential design issues. These prototypes are often used to test the aerodynamics of new designs.


Prototyping validation

Fine precision, smooth, and precise 3D printed size replicas are frequently used in the automobile industry to illustrate new car designs and concepts. The explanation is straightforward: utilising CAD models by itself is insufficient for defining potential design issues. These prototypes are often used to test the aerodynamics of new designs.


Preproduction sampling and tooling

This application is regarded as one of the most viable among 3D hub professionals. Molds and heat treating tools, as well as grips, jigs, and fittings, may be created via 3D printing. This enables manufacturers to generate low-cost prototypes and equipment while eliminating future production losses caused by high-cost machining investments.


Customized parts

Automotive companies employ additive manufacturing to customize parts to individual vehicles (customizing them and making them lightweight) or perhaps even operators (drivers seats for race cars). This is best suited when the expense of such one-of-a-kind components is offset by a significant gain in engine efficiency.


Advantages of 3D Printing in The Automotive Industry

Printing methods for the automobile sector offer advantages that are immediately quantifiable in accordance with the performance parameters. 3D printing has the potential to replace costly and time-consuming CNC manufacturing.

Since everything is manufactured on-site, in-house 3D printing can also assist to regulate Intellectual Property (IP) breaches or data leakage. Additionally, 3D prototyping may drastically cut turnaround times throughout all phases of production, allowing for greater flexibility. When compared to conventional techniques to automobile engineering (this includes both cars and trucks), which employ a range of materials, 3D printing in automobile manufacturing offers decreased material consumption and waste, which benefits all phases of manufacture.

In the automobile sector, 3D printer aided design enables designers to test various possibilities for the same detail and revisions during the development stages of a new model. It provides additional flexibility, resulting in more efficient designs and the ability to make design modifications during the model review process. This, in turn, assists automakers in staying current with market demands and staying ahead of the competition.

The capabilities and benefits of 3D printing in the automobile sector has been discovered, b ut it must be noted that this benefit is comprised of two parts: 3D printers and 3D printing software.

3D Printing Software in The Automotive Industry

Using commercial 3D printing technology, 3D printing enables a more efficient automotive model construction, development, testing, and execution. This system allows engineers to produce designs that can be printed, which are perhaps the most important stage in manufacturing 3D printed vehicle parts.

To fully utilize a 3D printer’s potential, one must have 3D printer control systems and 3D editing software that permits the gear to accomplish specified jobs. All programmes must adhere to particular standards, which means it must “prehend” diverse data input formats.

Generally, 3D printer software makes use of:

3D printing handled by software that responds to your individual demands instead of the industry norm can result in more substantial cost reductions (labor expenses, equipment utilization, product cost, etc.) and a considerable decrease in production time. 3D printing software has the potential to streamline the manufacturing process and assure lean production.

When it comes to small-scale enterprises that attach “custom” at their center, like customized car manufacturer Ringbrothers, 3D printing auto parts has made available various efforts to manipulate and push the efficiency and inventiveness of their project, ensuring adequate room to try and come up with and create flawless new features without worrying about the possibly high expense and time consuming production methods that come with personalization. This is also proved convincingly by the Italian start-up X Electrical Vehicle (XEV). XEV went on to introduce the first electric automobile in China in the second quarter of 2019 in collaboration with the Chinese business enterprise Polymaker.

Big businesses are also using 3D printing technology with older methods. Volkswagen resurrected their classic 1962 Microbus, turning out the gas engine for a 120 horsepower, 173 lb-ft torque turbo chargers. The “Type 20” idea also includes a number of enhancements made possible by 3D printed pieces, such as generatively built cast aluminum rims. The hubcaps are 3D printed as well: while they appear to be pressed steel, they were really manufactured on a Formlabs SLA 3D printer and then electroplated to mimic metal components.

However, the uses of 3D printing are not restricted to classics and idea or show models. Twikit’s customization software has enabled British carmaker MINI to provide bulk personalization services for their vehicles with the use of 3D printing, allowing consumers complete design freedom. Clients may personalize the interior and outside of their automobile with a variety of typefaces, patterns, and photos, and assess their layout using 3D simulations. The price cuts offered by generic 3D printed elements have enabled this type of customization feasible to the general population, which is critical for the market feasibility of such a project.
