The best 3D printing videos of 2021


The year 2021 is over, and like every Sunday, 3Dnatives takes a look at some of the best videos, although this time around it’s the last 12 months rather than the week. Between building houses, bridges, robots or auto parts, technology has developed a lot over the past year. Other industries, such as medical and aerospace, have also been affected by advancements in technology. In addition, the return of physical events, such as Formnext, the world’s largest exhibition dedicated to 3D printing, brought together industry players. Through these 10 3D printing videos, relive some of the most striking innovations of 2021!

A 3D printed ocular prosthesis

A few weeks ago, we learned about the case of Steve Verze, a London resident who became the first person in the world to receive a 3D printed ocular prosthesis. The prosthesis was developed in collaboration between several agents in the UK and Europe, as part of a project led by researchers at UCL and the Moorfields Eye Hospital NHS Foundation Trust. In this video, see how 3D printing allowed Steve to regain his self-confidence thanks to the ultra-realistic appearance of the prosthesis, which is also adapted to the shape of the orbit.

Large format machines at Formnext 2021

One of the biggest 3D printing events the industry saw in 2021 was without a doubt Formnext. Organized in Frankfurt in mid-November, this event brought together the main players in the industry in one place after several months without the possibility of physical events. And to bring you all the news from the 2021 event firsthand, the 3Dnatives team has produced a series of videos featuring the show’s most remarkable machines, applications and innovations. Concretely, in this video, discover the 5 large format 3D printers that we saw in Frankfurt, in particular on the CMS, Triton, CEAD, Cubicure and MX3D stands. Discover the characteristics of these five machines below!

The Striatus bridge printed in 3D

Among the various 3D printed bridges this year, we would like to highlight the Striatus Bridge. The project was carried out by a group of architects from ETH Zurich who, together with Zaha Hadid Architects and Incremental3D technology, successfully designed this pedestrian bridge. It is a 12 x 16 meter long bridge that was installed by putting together several individual pieces in a park in Venice. Thanks to 3D printing, concrete was only applied at certain angles, which meant that the bridge did not need any additional reinforcement. We let you discover the rest of the details in the video!

Try the Adidas 4DFWD

The combination of 3D printing, shoes and sports is certainly something that we have seen throughout 2021. In fact, the so-called Adidas 4DFWD were launched in May of this year by the German manufacturer in collaboration. with the 3D printing company Carbon. What is striking about these sneakers is that the midsole was created using resin additive manufacturing. According to the authors of the project, this design should allow athletes to generate more thrust during the exercise thanks to the trellis structure of the midsole. To learn more about these shoes, we let you watch this video where a user puts them to the test.

The role of additive manufacturing in construction

While additive manufacturing takes center stage in the construction industry, many companies have started 3D printed house projects. What once looked like science fiction is now a reality. Thus, companies like WASP, ICON, Mighty Buildings, TAM and many others have taken advantage of 3D printing to bring their innovative projects to life. To learn more about the rise of technology in construction, at 3Dnatives we wanted to take a look at some of the most popular 3D printed homes in recent months. Will additive manufacturing be the main method of building houses in the future?

Atlas, the Boston Dynamics robots

This is undoubtedly one of the 3D printing videos that went viral in 2021. It is an obstacle course made by the so-called Atlas, humanoid robots printed in 3D. The development of the robots was carried out by the company Boston Dynamics, which aims to test the limits of the possible by combining 3D printing and robotics. Specifically, Atlas prototypes have certain components 3D printed, such as legs or other parts of the final structure. Do not miss the incredible video where the robots do all kinds of jumps on their own!

3D printing of bones with living cells

Advances in additive manufacturing in medicine are revolutionizing the industry, allowing the development of exciting projects ranging from prostheses to 3D printed organs. In this case, we’re going to watch a video in which Kris Kilian, a researcher at the University of New South Wales in Sydney, explains a new initiative using this technology. Specifically, his research team has developed an ink that could allow surgeons to create 3D printed bones using real living cells. If you want to know more about this project and its impact on the medical sector, don’t miss the video below!

3D printed rockets for space exploration

Over time, more and more projects using additive manufacturing are emerging in the aeronautics sector, whether for the creation of parts and tools or large-scale structures. The increasing implementation of 3D printed rockets in industry allows companies to reduce the weight of final parts as well as production times. To learn more about the benefits of this technology in space exploration, we’ve provided an update on the main projects to date. Discover the activity of large companies such as Relativity Space, Hyperganic, SpaceX or SPEE3D!

The TECLA project uses sustainable resources

Although we have seen several videos from 2021 that use 3D printing in the construction industry, we could not leave out the TECLA project, one of the ones that marked the year 2021 the most. the Italian company WASP, these structures were created with natural and sustainable materials, using their exclusive construction 3D printer. The innovative housing model created by WASP aims to implement a new circular housing model created entirely with reusable and recyclable materials, from local soil, carbon neutral and adaptable to any climate and context.

3D scanning of difficult surfaces

Another video that caught our attention in 2021 was brought to you by HandsOnMetrology. The company has released this short video in which it aims to solve a big question that many industry users have on a daily basis: How do you 3D digitize the most difficult areas of a part or model? To do this, he shows the case of the IndyCar RLL racing team, who needed to scan the windshield of a racing car, which was complicated because the laser passed through the surface. For this, they used a 3D scanning mattifying spray which allowed them to cover the surface, achieving a much cleaner and better end result.

Ford and BigRep additive manufacturing

Another 2021 video highlight comes from Ford Motor Company. In this case, the famous automaker used BigRep’s large format additive manufacturing to optimize tooling production in the factory. With more than 30 years of experience in additive manufacturing, Ford has expanded its Cologne prototyping plant with two BigRep solutions. This integration of 3D technology has enabled Ford to reduce delivery times by 94%, as well as final costs. All of these investments in additive manufacturing machines highlight the growing popularity of the technology in many areas, especially in the automotive industry.
