डायरेक्ट साउंड प्रिंटिंग (DSP)

In 2022, a method of 3D printing using sound waves was introduced to the market. This strategy leverages sound waves to harden print material into a desired shape. Sound Waves are used to create cavitation which occurs whenever the static pressure drops below vapor pressure in a liquid. This state creates milliseconds of high pressure and heat. This heat is used to harden 3D printed materials quickly.

होलोग्राफिक डायरेक्ट साउंड प्रिंटिंग (HDSP)

Researchers proposed an upgrade to the current DSP method in a recent article published in the journal Nature Communications called Holographic Direct Sound Printing (HDSP). This new approach utilizes acoustic holograms to improve the process. The hologram uses specially patterned acoustic waves that induce cavitation bubbles at specific locations.

The chemically activated acoustic cavitation bubbles provide real-time on-demand regional polymerization, enabling researchers to print using sound more effectively and with more detail. According to the study, the printing process allows engineers to examine and store cross-sectional images of desired prints, enhancing design capabilities and enabling researchers to improve internal structuring.

The HDSP printer is set up in a manner that is reversed to many of its predecessors. Rather than the printing arm moving, a motorized platform moves the material within the stationary holographic image. The system utilizes pre-programmed patterns based on advanced algorithms to navigate the robotic arm around the holographic image, enabling the sonochemical reactions to occur and harden the print.

The research paper discusses the testing methods used to qualify the new additive manufacturing process. Researchers conducted a series of sono-chemiluminescence and high-speed imaging experiments to gauge the capabilities and performance of the HDSP. Specifically, key details were tracked including a detailed account of the polymerization process, tuning effects, robotic movements, and software computations.

The results of the study are game-changing. For one, the researchers noticed that there was a direct correlation between feed rate and their ability to make alterations to complex prints. As such, the team integrated advanced software algorithms to optimize parameters based on the needs of each print. This maneuver resulted in highly accurate printed structures that could outperform previous designs.

The team went on to research the HDSP’s ability to print across a variety of different materials. They also tested the effects of the holograms on the process under different levels of intensity, design, and placement. Lastly, they examined how different structures, such as porosity and materials, affect the tuning process.

The most important breakthrough of this research revolves around remote printing. The engineers found that they could print objects behind walls and other structures using HDSP. This method of internal printing could enable a future where your car parts are printed in place rather than installed. Even more impressive, the same strategy could be used to print organs or repair internal damage in a non-invasive manner.

होलोग्राफिक 3डी प्रिंटिंग के लाभ

The researchers put forth a compelling case as to why HDSP outperforms DSP across nearly every category. For one, it’s much faster than the original DSP method which was limited to a voxel-by-voxel printing strategy. HDSP enables multiple areas to undergo hardening at the same time. The results are that you can print up to 20x faster using DHSP methods.

Another benefit that HDSP introduces is the ability to alter images during the printing process. In a traditional method of 3D printing, each layer is applied and hardened, meaning that there’s no way to make alterations if the component is already added. HDSP users can alter the hologram, which automatically changes the printing with minimal effort. As such, there’s less waste as this approach reduces printing errors.

HDSP opens the door for a new level of complexity within the market. This printer can create intricate designs with internals utilizing soundwaves, enabling engineers to develop more effective, lightweight options without sacrificing performance and durability.

मल्टी-प्रिंट

Another game-changing advantage the HDSP offers is the ability to create objects simultaneously. The system allows you to maximize efforts by combining multiple prints during a single session. The system can accommodate different prints at different locations, maximizing printing space and lowering print times.

The HDSP unit is a versatile device that introduced a new level of flexibility to the market. Users can alter printing materials, create intricate shapes, and print across opaque surfaces using this method. This added flexibility will result in further innovation and collaboration across industries.

असाध्य स्थानों में प्रिंट करना

Another great benefit that HDSP brings to the table is its ability to print in nearly impossible-to-reach locations. Imagine parking your car and a repair drone notifying you that they are going to print you a new fan because your old one is broken. Now, rather than popping the hood, a holographic image is being used to print your new fan in location, no installation is required.

There are several potential use case applications for HDSP technology, which could provide some much-needed boost in capabilities across markets in the coming years. Here are the top potential use case applications for HDSPs.

स्वास्थ्य देखभाल

The use of HDSP in the medical and biomedical field will help to lower costs, improve patient safety, and expand access to more regions of the world. HDSP systems are capable of printing complex tissue structures,  drug delivery vehicles, and even skin grafts. All of these options improve survivability over their predecessors and can be printed internally, eliminating the need for invasive surgeries.

Researchers at Concordia’s Department of Mechanical, Industrial, and Aerospace Engineering conducted the research and testing of the HDSP process. Specifically, a professor named Muthukumaran Packirisamy led the team. Funding for the project came from grants sponsored by  FQRNT (Fonds de Recherche du Québec, Canada), NSERC Discovery of R.B., and the Concordia Research Chair.
