7 curiosities about 3D printing you cannot miss

The world of 3D printing is a constantly evolving and mutating one – something a lot of people don’t realize! Its progress is closely linked to the technological innovations that are emerging at all times and we’re going to figure out more about that in this article, exploring some curiosities about 3D printing that you may not know. We bet that some of them will really surprise you! At first glance, it may seem a very complex technology, and sure, there are some challenges, but the reality is that it is becoming more and more democratized and, therefore, more accessible to everyone.

Reuse of plastic waste (and therefore creation of a circular economy)

Ever heard that 3D printers are potentially great for our planet? They could actually be one of the most sustainable alternatives to conventional manufacturing, as 3D printing generates hardly any waste, because only the essential amount of material is used.

We love the sustainability factor, which is heavily due to it using otherwise single-use plastics, repurposing them and giving them a brand new lease of life! With this kind of tech, we might even be able to put an end to single-use plastic waste, prioritizing a circular economy.

This technology also simplifies the production process of parts and components, thus reducing the time and costs of making something, and synthesizing the use of machinery and technologies to cover the entire process. And that’s not all – 3D printing technology goes one step further and opens up a world of possibilities in terms of materials.

The manufacturer UltiMaker has available in its UltiMaker Marketplace different materials made from filaments of other prints, which are recycled to create new high-end materials.

4D printing is on the way

Technology is advancing in leaps and bounds, and the evolution of 3d printing is surging forward too! In recent years, the work in many areas has been done by 4D printing, which involves manufacturing with materials that can change their nature when in contact with water. At the same time, research is being carried out so that they can adapt to other environments and, once immersed in them, adopt the desired shape.

In a way, this modality aims to use more special materials that react in certain ways to external stimuli. In order to manufacture elements with these characteristics, a much more complex design process is needed – but wow, the payoffs are huge!

Manufacture of buildings and houses

Ever thought about 3D printing a house? It sounds pretty crazy, right? But… well, actually, this tech is already creeping into sectors like construction, where it is gaining prominence in the manufacture of buildings and houses, as it represents a great boost to the sustainability of the sector.

Through 3D printing technology, spectacular buildings and houses can be built without the transportation and logistical costs involved in traditional construction. 3D printing allows the entire manufacturing and construction process to be carried out in the same space, thus decreasing the long lead times common in this sector.

In addition, the manufacture of buildings and houses through 3D printing can be carried out using recyclable elements, avoiding the generation of waste. In this way, buildings focused on the reduction of emissions are obtained, which represent a real alternative to the problems of the cement industry.

First bridge manufactured by 3D printing

Recently, a great step forward in architecture and 3D printing has been taken with the world’s first 3D printed bridge. This is a very new development in the tourism sector too, as it could become a major tourist attraction for the city in which it is located – in this case Amsterdam.

This 3D printed bridge has been manufactured with the purpose of replacing one that needed to be repaired. Not only that, but it’s also an opportunity to test its resilience and thus verify if this innovative approach works well!

The material used is stainless steel and so far, they have ensured great stability for the large number of tourists visiting the streets of the Dutch city. This is a momentous step – to quote a certain astronaut, “one giant leap for mankind,” and all that…

Production of tissues and organs for the medical sector

Did you know that 3D printing could also bring significant changes in the healthcare sector? Who would have thought you could reproduce a heart in 3D? Yet today it is becoming feasible!

Broadly speaking, 3D printing technology allows total customization of treatments, as well as the manufacture of disposable surgical material. The result is a very considerable reduction in surgery times, and waiting and recovery periods, and offers cost savings.

One of the most important applications of 3D printing in the healthcare sector is in the production of prostheses and implants. This technology allows customization down to the millimeter to adapt to the needs and requirements of each patient.

Additionally, 3D printing makes it possible to improve the precision of surgery, since replicas of organs can be used to plan how the operation will go before it is carried out. In addition, it improves communication with the patient, since understanding medical language can sometimes be complicated, and thanks to 3D replicas, the patient understands the diagnosis and treatment much better.

Did you know that it is possible to print edible food and kitchenware?

3D printing never ceases to amaze! This technology has gone a step further and now even makes it possible to generate completely edible food from fresh ingredients such as chocolate, fruit or pasta. After all, thanks to this technology, it is possible to print geometrically complex pieces that would be impossible to obtain with other types of technology. The result is therefore dishes with a highly refined visual aesthetic and completely refined, a truly unique experience.

Cooking enthusiasts know that the tools used are never enough! 3D printing makes it possible to create gadgets according to very specific needs. Is your mouth watering yet? You should try it out!

Alternatives to testing cosmetics on animals

A few years ago, it was possible to obtain a way to 3D print synthetic skin that works effectively as an alternative to human tissue for testing cosmetics on animals.

As you may already know, cosmetic experimentation uses testing on animals, such as rats or rabbits, which are subjected to different treatments with different products and are not subjected to any kind of alternative to relieve their skin afterwards.

3D printing is a great option to put an end to animal experimentation (the animals would be really grateful), by cosmetic or pharmaceutical companies, as it allows the same testing to be carried out, but on synthetic fabrics.

3D printing is a very rapidly evolving field

We can’t help but notice: 3D printing is growing so fast, and it’s hard to keep up with all the innovations in this technology! If you are interested in this topic, you should definitely keep up to date with the latest news as it is an extremely interesting field especially since it has a great future ahead of it, and we can’t wait to find out the new innovations! Also, as you have seen, 3D printing can be a great ally for taking care of our planet, our bodies, and our animals! Are you ready to make your contribution toward sustainable innovation?


In conclusion, 3D printing is a revolutionary technology that continues to evolve and impact various industries. From its surprising applications in medicine and fashion to its potential in construction and aerospace, 3D printing is pushing the boundaries of what is possible. As advancements continue, it is poised to become even more integral to manufacturing, healthcare, and beyond. Understanding these curiosities not only highlights the current state of 3D printing but also offers a glimpse into the exciting future of this innovative technology.
