Gone the days that 3D printing was science fiction. 3D printing has entered our daily lives and it is here to stay. By using 3D printers, people are able to create/develop unimaginable things.
Bellow is a list of cool items created by using 3D printers.
1. 3D printed organs
When we talk about 3D printed organs, we don’t mean only printing some kind of robotic hand like Luke Skywalker’s one, but we really mean real 3D printed organs.
3D printing is going to change the health industry. In the near future, your doctor might be able to 3D print your missing ear or other missing parts of your body. No, it is not science fiction anymore. Scientists have already succeeded bioprinting ear made from children’s own cells. Also, scientists at Tel Aviv University (TAU) have succeeded bioprinting the world’s first 3D vascularized engineered heart. They achieved that by using a patient’s own cells and biological materials.
2. A 3D printed boat
In October 2019, the University of Maine revealed the world’s largest 3D printed boat. The boat had a length of 25 feet (7.62 meters) and weighted almost 5000 pounds (2.25 metric tones). The boat named 3Dirigo, was 3D printed with the additive manufacturing process from a mixture of plastic and wood cellulose.
The team of the project was awarded 3 world records: 1) the largest 3D printed solid part, 2) the largest 3D printed boat and 3) the largest 3D printer. 3Dirigo took almost 72 hours to be printed. Bellow you can see a time-lapse of the world’s largest 3D printed boat.
3. 3D printed houses
Lately, 3D printed houses are popping up all around world like mushrooms. The 3D printing technology has advanced so much that it is now able to build houses in a single day.
An example of it comes from the construction company Apis Cor. Apis Cor was able to 3D print a house in 24 hours with a cost a bit more than $10,000. The house has an area of 400 square feet (38 square meters). The main components of the house’s structure were fabricated on site by using concrete. This dramatically cut down costs on transportation and assembly. It is predicted to be durable enough to last up to 175 years.
3Dvarius, is one of the only companies in the world that succeeded producing commercial grade 3D printed violins. It started as personal project and challenge. That was to design an electric violin which wouldn’t weigh more than a classic, wooden acoustic one.
The violin got printed with the Stereolithography process. This process is using UV laser to polymerize liquid resin which is photosensitive. The violin made its debut in a Kickstarter campaign where 3Dvarius pledged €53,231 (around $63,294) out of their €50,000 initial goal.
After their successful Kickstarter campaign, 3Dvarius currently has a series of 4 different electric violins in their product line up.
3D printing allows the fabrication of large components with highly complex internal structure that otherwise it would be time consuming. The ability to significantly reduce the time and the associated costs of the fabrication of mechanical components is the driving force for various manufacturers that start fabricating their components by using the 3D printing technology.
Relativity Space, is one of such companies to embrace the usage of 3D printing. Their Terran 1 rocket is made by a proprietary 3D printed alloy. 3D printing, allows them to reduce the parts count of the rocket by 100x, simplifying the design of it and lead times. The Terran 1 rocket is consisted of 730 parts and it is much more simple to fabricate compared to rockets from other manufacturers that are made from more than 60,000 parts.
6. 3D printed cars
Lately, there have been done huge efforts by car manufacturers to produce 3D printed cars. The Czinger 21C is a 1,233bhp hypercar where large sections of its chassis are 3D printed. An other example is the Strati, an electric car developed by Local Motors. The car was manufactured during the 2014 International Manufacturing Technology Show in Chicago, Illinois.
This was done by using a large scale 3D printer. It took just 44 hours to print and it was followed by three days of milling and assembling. The completed car was first test-driven on September 13th, 2014. Depending on the battery packs of the car, the range of it can be from 100 to 120 miles (160 to 190 km) and can achieve top speeds of 40 mph (64 km/h).
Currently, we do not have any news about Strati. As such, we believe that Local Motors didn’t continue the development of it.
