Harvard engineers develop true 3D printing technology

Researchers have developed a 3D printing technique that goes beyond the traditional layered bottom-up approach and eliminates the need for support structures.
Description published in the journal Nature.
Read Hi-Tech in
A team of researchers led by scientists from the Rowland Institute at Harvard University has developed a new 3D printing technology. The engineers used a method of converting red light to blue and adding a photosensitive liquid to a resin used in 3D printers.
In traditional 3D printing, resin solidifies in a flat and straight line along the path of light. In their work, the researchers add nanocapsules containing special chemicals to the resin so that the resin reacts only to a certain type of light - blue light at the focus of the laser. Such a beam is formed in the process of frequency upconversion. The beam travels in three dimensions, so it doesn't need layering. As the researchers note, the resulting resin has a higher viscosity than the traditional method, so after printing it can stand without support.
“We designed the resin, we designed the system so that the red light does nothing,” says Daniel Congreve, co-author of the study.
“But a small dot of blue light triggers a chemical reaction that causes the resin to harden and turn into plastic. What this basically means is that you have a laser going through the whole system and only in that little blue do you get polymerization, [and only there] do you get printing. We just scan that blue dot in three dimensions, and wherever that blue dot hits, it polymerizes and you get 3D printing.”
The researchers demonstrated their printer and created 3D Harvard and Stanford logos and a small boat. This is a standard test for 3D printers: the small size of the boat and many small details, such as overhanging windows and open spaces in the cabin, create a challenge.
The authors of the development believe that the technology can seriously change 3D printing. Traditional layering requires the use of props for overhanging elements to keep the resin from sinking and dripping down. Refusal of such structures will significantly speed up the process.
Engineers plan to continue developing the system to increase speed and print even finer details.

3D Printing Applications
3D printing is used for applications such as visualization of modeled designs, prototyping, metal casting, as well as in architecture, education, mapping, medicine, entertainment and retail.
In addition, 3D printing technologies can be used to reconstruct fossil objects in paleontology, create copies of the most valuable ancient artifacts in archeology, restore bones and body parts in forensic science, and reconstruct badly damaged evidence obtained during an on-site investigation.
crimes.
In 2007, it was proposed to use 3D printing to create art. Since then, sculptors, designers, and other visual artists have found various ways to apply 3D printing technologies.
In addition, scientists and companies in the field of biotechnology are actively researching the use of 3D printing to create organs and tissues using inkjet printing. Such methods are reduced to the layer-by-layer introduction of living cells into a gel medium for the gradual production of a three-dimensional object. This area of development is called by various terms: printing of organs, printing with biomaterials, automated creation of tissues.
Industrial 3D printing
Over the past few years, 3D printing has become more known to the general public. However, most people still haven't even heard of this technology, even though it's been around for decades. In particular, in industry, 3D printing technologies have long been used to create prototypes in the development and design process, this process is called rapid prototyping.
The use of 3D printing for this purpose results in significant savings in time and money. A company can spend tens of thousands of dollars to install a 3D printer, but much more can be saved with rapid prototyping. Nike, for example, is using 3D printing to produce multi-colored athletic shoe prototypes. Prior to the introduction of 3D printing, the company spent thousands of dollars on prototyping and had to wait weeks for an order to be completed. Prototypes now cost hundreds of dollars to make, and if changes need to be made, they can be added to the computer model immediately and the modified prototype ready the same day.
In addition to rapid prototyping, 3D printing is also used for rapid production. The term refers to a new manufacturing method in which 3D printers allow companies to produce specialized and unique products in a short time frame. In other words, in this case, using 3D printing, you can get not a prototype, but the final product intended for the consumer.
At the same time, modern technologies allow creating unique products that meet the specific requirements of the consumer.
Personal 3D printers
Personal 3D printers designed for home use are mainly popular among hobbyists and enthusiasts. This segment of the market began to grow around 2011. Due to the rapid development of technology and increasing competition, prices for personal 3D printer models are constantly decreasing and today are in the range of $250 to $2,500. As devices become more affordable, 3D printing is becoming more widespread.
The hobbyist 3D printing market has been boosted by the creation of the open-source RepRap project. Consumers were able to purchase a RepRap kit for around $1,000 and build their own 3D printer with whatever modifications and additions they could think of and implement. The real driving force behind the project was the idea of openness of information. Everyone involved in RepRap shares their knowledge and experience with others so that the ideas are constantly refined and improved by the community.
The rapid development of open source 3D printers is of growing interest in both developed and developing countries. This approach allows not only to create a unique device that best suits the needs of an individual user, but also to share developments with a community of like-minded people through platforms such as Thingiverse and Cubify. This technology is also sustainable, as it can easily be used to create objects from available materials directly in the local community and in accordance with their needs.
3D printing services
Not everyone can afford or want to buy their own 3D printer. However, this does not mean that you cannot take advantage of the possibilities of 3D printing technologies. There are companies that provide 3D printing services such as Shapeways and Ponoko. For a relatively small fee, these companies will print and send you a 3D printed item based on a digital design that can be uploaded to the site using a simple system.
