DISH: New Tech Prints 3D Objects in Under 1 Second

The way we manufacture objects is currently undergoing a quiet but profound transformation. For ages, the world of impresión 3D has been defined by a slow and steady approach. Most people are familiar with the sight of a printer nozzle moving back and forth, slowly depositing layer after layer of plastic to build an object from the bottom up. While this method changed how we prototype new ideas, it has always struggled with a fundamental problem: it is incredibly slow. If you want to make something with a high level of detail, you have to wait hours or even days, and if you try to speed it up, you lose the precision that makes the object useful.

A new breakthrough¹ in a field called volumetric additive manufacturing is about to change that. Instead of building an object layer by layer, scientists have found a way to create the entire object at once. This is not a gradual process of stacking materials; it is more like a photograph coming to life inside a container of liquid resin. A recent development known as DDiseño y artes digitales, Incoherent Synthesis of Holographic light fields, or DISH, has pushed this technology to a point where complex objects can be created in less than one second.

Overcoming the Limitations of Traditional Volumetric Printing

To understand why this is such a significant leap, it helps to think about the limitations of current technology. In standard volumetric printing, a container of liquid resin is typically rotated while images are projected into it from different angles. As the light hits the liquid, it triggers a chemical reaction that turns the liquid into a solid. However, rotating the container creates physical problems. The movement can cause vibrations that blur the final object, and the heavy resin can cause the newly formed parts to sink or drift before they are fully finished. This meant that researchers had to use very thick, syrupy resins to keep everything in place, which limited the types of materials and objects they could create.

The DISH method solves this by keeping the liquid perfectly still. Instead of spinning the sample, the system uses a high-speed rotating periscope to move the light around the container. This periscope works in tandem with a sophisticated set of digital mirrors that can change the shape of the light thousands of times per second. By using holographic optimization, the system can ensure that the light is perfectly focused even deep inside the container. This allows for an incredible level of detail, with stable printing resolution of about nineteen micrometers being produced across a relatively large area. For perspective, a human hair is roughly seventy micrometers wide.

Comparing 3D Printing Technologies

Industrial Potential and Mass Production

This technology is disruptive because it bridges the gap between laboratory experiments and real-world mass production. By integrating the printing system with a fluid channel, the researchers demonstrated that they could print an object, wash it away, and immediately print another one in a continuous flow. This moves 3D printing away from being a tool for making one-off hobbies and toward being a viable method for industrial manufacturing.

The potential applications for this speed and precision are vast and span across several critical industries:

• Médicos profesionales could use this to print personalized dental implants or hearing aids in the time it takes for a patient to finish a short conversation.
• Biological researchers can print delicate scaffolds for human cells using soft hydrogels that would normally be too fragile for traditional printing methods.
• Compañías farmacéuticas could use the technology to print thousands of tiny, complex structures for drug testing, allowing them to see how new medicines interact with 3D shapes much faster than before.
• Engineers in the optics industry could print tiny lenses and light-guiding components for smartphones and sensors with almost no post-processing required.
• Manufacturers of specialized machinery can create intricate internal parts that are impossible to make with traditional molds or drills.

Because the process happens so quickly, it also allows for the use of materials that were previously off limits. Many high-performance resins begin to settle or separate if they sit for too long, but with a printing time of just zero point six seconds, the object is finished before the material has a chance to change. This opens the door for new types of elastic, rigid, and biocompatible materials that can be used in everything from flexible electronics to internal medical devices.

Invertir en innovación en impresión 3D

As these laboratory breakthroughs move toward the commercial market, investors are looking for companies that have the infrastructure to turn holographic printing into a standard industrial process. One of the most prominent names in this space is 3D Systems. While many companies focus on the consumer side of printing, 3D Systems has spent the last several years positioning itself as a leader in high-end industrial and medical applications.

The company made a significant strategic move in recent years by acquiring Volumetric Biotechnologies, a firm specifically focused on the challenges of printing human tissue and organs. This acquisition aligns perfectly with the advancements seen in the DISH research.

By focusing on regenerative medicine and bioprinting, 3D Systems is moving beyond traditional manufacturing and into the future of healthcare. Its goal is to create vascularized tissues, which are complex structures of blood vessels that can support living organs. The speed and stationary nature of holographic printing are exactly what is needed to handle the delicate biological materials required for these medical miracles.

Beyond healthcare, the company provides the hardware and materials for aerospace and automotive companies that require the highest level of precision. As volumetric printing matures, the ability to integrate these fast, stationary light systems into existing production lines will likely become a major competitive advantage.

For those watching the evolution of manufacturing, the transition from slow, mechanical layering to near instant light-based creation represents the next great frontier in the industry.

Una nueva era de fabricación

Looking ahead, we can expect this technology to continue shrinking in size and growing in capability. While the current systems are designed for millimeter-scale objects, the principles of holographic light control can be scaled. Eventually, we may see large-scale versions of these printers that can create entire car components or structural elements in minutes rather than days. On the other end of the spectrum, the ability to print directly onto surfaces or even inside existing structures could lead to new ways of repairing machinery or performing minimally invasive surgeries.

The most exciting aspect of this development is not just the speed, but the democratization of complex design. When it takes hours to print something, every mistake is costly. When an object can be created in less than a second, the cost of experimentation drops to nearly zero. This encourages a new level of creativity and rapid iteration that will inevitably lead to better products and more efficient solutions to global problems.

The transition from 3D printing as a slow hobbyist tool to a lightning-fast industrial powerhouse is no longer a matter of if, but when. As holographic light fields become easier to control and the software behind them becomes more accessible, the physical world will start to feel a lot more like the digital world. We are moving toward a future where if you can imagine an object and design it on a screen, you can have it in your hand almost as fast as you can blink.
