If you've been keeping up with science and technology news recently, you've been thinking a lot about AI and/or rockets.
However, you shouldn't ignore 3D printing, a highly inventive tech industry that is expected to experience explosive development. Most likely, the fastest manufacture of tiny, specialized mechanical parts is where 3D printing is most helpful.
But technology can also create really big things and structures. Here is the list of the biggest item ever created by one of these quickly developing object-building machines in case you need a reminder of what's possible with them.
1. Titanium Brake Caliper by Bugatti

Undoubtedly, one sector that benefits the most from 3D printing technology is the automobile industry. One of the market leaders, Bugatti, didn't wait for their rivals to begin reaping the advantages of additive manufacturing. They are employing the Selective Laser Sintering (SLS) method to develop a new route for manufacturing.
Bugatti significantly improved the design and production of their brake callipers as a result of 3D printing. The brake created using conventional techniques was composed of aluminium and weighed 4.9 kg.
The experts were able to employ titanium, which is significantly stronger and more resistant, thanks to additive manufacturing. In addition, they could reduce the weight of the calliper to 2.9 kg by using innovative design techniques!
Due to their resources and workforce, Bugatti can pioneer ideas that should eventually be adopted by other VW Group companies like Audi and Lamborghini. The entire 3D printed car industry is hoped to advance significantly as a consequence.
If you want to witness this incredible 3D-printed brake calliper while you're in London, go to Berkeley Square and take a closer look at the Bugatti store. If you're lucky, the 3D-printed calliper will be on display in a glass case!




2. Two-level villa

Buildings that have been 3D printed in the past constitute some of the largest 3D printed objects. Nevertheless, HuaShang Tengda from China provides a particularly excellent example. They used their own concrete 3D printing equipment and finished the on-site 3D printing of a two-story villa in just 45 days.
The pace at which homes are produced utilising additive manufacturing is revolutionary. In just 45 days, HuaShang Tengda completed a two-story mansion! They not only created specialised hardware but also a cutting-edge 3D printing augmentation method. A 3D printer was used to lay the concrete after the building's structure had already been constructed.
Twenty tonnes of concrete were utilised to create this enormous sculpture! Another benefit of additive manufacturing is less material waste, which lowers prices.

This is demonstrated by the 3D-printed house. The timeline is still the most astounding. Your production may be enhanced by 3D printing by becoming faster and less expensive.

3. The largest 3D printed bridge

A well-known business in the construction industry is Shanghai Mechanized Construction (SMC). They contributed to the construction of the Shanghai skyscraper and the drilling of Shanghai's subterranean network. Their next project is a single-piece 3D-printed bridge that will be put in a park in the heart of Shanghai. The bridge is the result of a partnership between SMC and Polymaker and is printed in plastic.
With a construction area of 144 m3, the printer used to create the bridge is currently the biggest plastic 3D printer in the world. The finished printed bridge will be 15.25 metres long, 3 metres broad, and 1.2 metres high and weigh 5.8 tonnes.
Acrylonitrile styrene acrylate is utilised as the main component in the bridge's manufacturing (ASA). Glass fibres, which improve the structure's mechanical characteristics and lessen the likelihood that it would warp, makeup 12.5% of the structure.
The manner the bridge is maintained warm during the whole manufacturing is another interesting aspect of this endeavour. Heated blankets are employed to avoid unwelcome thermal expansions and to shield the bridge from dust because of its length.








4. Largest Wave Camper

The Wave, which is 13 feet long and 600 pounds heavy, was created in partnership with Saskatchewan Polytechnic. The largest indoor 3D printer in North America was used to produce it, breaking the previous record for the largest indoor 3D print.
Because he thinks 3D printing does bring a new wave of innovation to the industry, Randy labels his business Wave of the Future.
At a workshop organised by Create Café 3D Printing Solutions Inc., the entire printing process was streamed live on Facebook.

5. Aerospace Tool that Sets Records: Together with Boeing, Oak Ridge National Laboratory created a 3D-printed aerospace tool in 2016, and because of its size, it broke the previous record for the largest 3D-printed object. The Boeing 777x, a replacement for the well-liked 777 jet passenger aircraft, uses trim-and-drill technology to help in wing construction.
It was produced in one piece using ABS material that included carbon fibre reinforcement on a sizable, specially designed FDM 3D printer.
The object is 17.5 x 5.5 x 1.5 feet in size and weights 748 kg (1650 lbs)! The tool's print duration was 30 hours, which is quite rapid for such a sizable item.

6. Prudence the Golfer: There aren't many 3D printing-specific businesses in Croatia. A business by the name of Mikrotvornica stands out for having created a sculpture of a female golfer that is 190 cm tall and weighs around 18 kg.
Prudence is the name of the sculpture, which was created for the Dublin exhibition of Abigail O'Brien. Prudence was created with a Mikrotvornica FDM 3D printer. She is made up of 21 PLA plastic printed pieces.
After printing, all 21 pieces were assembled, sanded, and painted to give the golfer a brand-new appearance. Prudence is very breathtaking in person. The sculpture's extreme height as well as the fact that it was FDM produced are what most astounds people.

7. Stunning Sofa: Many FDM 3D prints have been examined, but what about SLA? The full-size lounger that you can see above was created using the ProX 950 industrial SLA 3D printer from 3DSystems. The largest component ever created on an SLA 3D printer is now Sofa So Good!
Only 2.5 litres of resin were used to make the lounger, which was then given a chrome and high-polish copper finish to improve both its strength and appearance.
Sofa So Good weighs only 2.5 kg and has dimensions of 1.5 x 0.75 x 0.55 m. It was created by Janne Kytannen and serves as the ideal illustration of how clean prints with intricate geometry can be produced with SLA.
8. Biggest Fidget Spinners: A firm and BigRep worked together to develop a massive, completely 3D-printed fidget spinner last year. What better way to demonstrate a printer's capabilities than this, given how well-liked fidget spinners were last year? Using BigRep's ONE, which has a remarkable build volume of 1 m2, to 3D print the toy.
BigRep's 3D printing expert advised printing the bearings in three dimensions to add even more intrigue, which they did!
The balls were immediately produced within the housing as a result of the bearings being 3D printed, which is a really neat feature. The body of the fidget spinner was 3D printed in 30 hours, while the bearings took 20 hours.

9. The Light Rider: The Light Rider is the first electric motorbike to be 3D printed, according to its makers. To be perfectly honest, it's more of an electric bicycle with a strong engine. The Light Rider's 3D printed frame was created by the German additive manufacturing business APWorks, which is owned by Airbus. It was produced utilising a special aluminium alloy powder and an SLS 3D printer.
The bike's frame was not created in one piece, but its components are nonetheless amazing. Each of them has a "bionic" design, which makes use of the least amount of material while still managing to reach the highest level of structural strength.
SelfCAD is a 3D modeling software that allows users to convert image to 3D. While it primarily focuses on 3D modeling and design, it does have features that enable users to convert 2D images into 3D models. With SelfCAD, you can import an image and use it as a reference or a starting point for creating a 3D model. The software provides tools that allow you to trace the image and create a 3D model based on its contours and shapes. By extruding and manipulating the model, you can give it depth and turn it into a 3D representation

10. World’s first 3D printed propeller: The marine sector is another business where 3D printing is a ground-breaking way to enhance the production process. The most recent innovation is WAAMpeller. It is the first ship propeller ever 3D printed. Where did it get its distinctive name?
An innovation created specifically for this project is WAAM. WAAM stands for wire arc additive manufacturing. Layer by layer, a metal wire is melted using this 3D technique.
The WAAMpeller is made of 298 layers of nickel aluminium bronze alloy. The finished product was both spectacular and useful! On a workboat named the Stan Tug 1606, a 3D-printed propeller was mounted.
