New 3D Printing Method
The new method called vapor-induced phase-separation 3D printing (VIPS-3D) promises to provide new capabilities while reducing costs for manufacturers. This new approach to 3D printing enables manufacturers to build more complex shapes using multiple materials including polymers, composites, and metals.
The University of Florida engineers used a new approach and chemicals to accomplish these tasks. The process began with researchers deciding on what 3D printing process to enhance. There are different methods and materials used in these applications and the researchers wanted to create a method of 3D printing that supported varying levels of porousness.
There are many use cases where porous materials are crucial. They are often more stable, lightweight, and use less material. As such, this sector of the 3D printing market has long been a focus of researchers seeking to improve operations. Here’s how this team of ingenuitive minds made it possible to print complex porous ceramic and metal shapes.
How VIPS-3D Works
The vapor-induced printing process used to enable this method of 3D printing is called non-solvent-induced phase separation (NIPS). It works by using a 3D polymer and composite materials to print. A nebulized non-solvent is used to dissolve polymer-based ink from the printed item as part of this process.

3D Printer Using Metal
Next, the low-volatility solvent removal process begins. The solvent gets extracted in a consistent manner which hardens the material evenly. This step enables the polymeric phase to begin to stiffen the material. Notaly, this process is more flexible in terms of material and shapes.
VIPS-3D Benefits
This method of 3D printing has some major benefits that industry professionals desire. For one, it enables engineers to scale key factors such as porosity. Additionally, they can spatially tune their creations, which enables the direct printing of functioning multi-material pieces when coupled with multiple materials.
Flexibility
Another major benefit is the added flexibility that VIPS-3d brings to the market. The process enables the use of a huge selection of materials. Engineers have proven the method works well in printing ceramic and metal items. This capability makes it possible to print complex shapes using multiple materials, including ones that leverage ceramic or metallic particles to provide structure.
The adjustability of this process is a huge plus which could help it find market use cases faster. The system enables users to set the inter-filament porosity and the inorganic space-holder. This option enables you to adjust printing conditions. For example, you could decide to make the item lighter and use less material simply by kicking up its porousness during manufacturing.
Economically
One of the main reasons there’s so much buzz around this new 3D printing method is that it’s more economical than traditional methods. The use of organic materials and new printing methods reduce costs significantly.
Additionally, since the project can adjust porousness, there is less waste or unnecessary ink usage. All of these factors add to the bottom line. For a firm that relies on 3D printing as part of its core business model, these costs make a difference.
Less Infrastructure Required
The researchers’ vapor 3D printing process has another added benefit: It requires far less infrastructure to set up, operate, and maintain. The use of non-solvent fluid enables the majority of it to be reclaimed. Additionally, this method of 3D printing uses a lot less electricity than existing methods. The use of the solvent allows the item to be locked into place without the need to reprint each section. As such, it’s easier to set up, move, and use.
Room Conditions
Notably, this method of 3d printing can be conducted under regular room conditions. This is a huge advantage for those seeking to print certain types of polymers and metals that can often require heat. VIPS-3D printing of polymeric, metallic, and composite materials can occur at room conditions with consistent results.
Reusable
The VIPS-3D method introduces a solvent reclamation system. This process enables the reuse of the non-solvent multiple times. After each session, the solvent gets removed and collected. This strategy ensures that it doesn’t get into the environment and saves money.
Sustainably Using Vapor-Induced Printing
One of the coolest aspects of this project is the use of eco-friendly liquids. These new 3d printer ink options leverage dissolvable polymer-based options that don’t harm the environment. As such, many predict 3D printing as one of the best ways to help reduce environmental impact.
Engineer Team
Notably, the research included mechanical and aerospace engineering professors Yong Huang, Ph.D., and Marc Sole-Gras, Ph.D. Notably, Sole-Gras is the lead author of the piece and was a former student of Dr. Huang. The team has filed for and received two patents as part of their research with the majority of funding for the research originating from the National Science Foundation and the Department of Energy.
Potential Applications
There are many applications where 3D printing porous materials are crucial to the completion of a task. There are times when you need to make the item porous so that it is lighter, enables air flow, or is more structurally sound. Here are the key industries that this development cold could affect
Healthcare
The creation of porous medical implants or other helpful healthcare items is a perfect example of how this technology could help millions of people live better lives. Already, the researchers have noted its potential in the field of bone tissue engineering.
This sector could see this method used to create realistic implants that match the porousness of other cells in your body. This approach would help to reduce the impact of prosthetics and implants by enabling them to better assimilate within your body.
Biohybrid Robotics
Another field that has a lot to gain from the integration of VIPS-3D is biohybrid robots. These devices are built to mimic or expand on natural mechanical processes. You can think of robots that resemble humans or other animals. They can even meld organic tissue with mechanical processes to accomplish impressive goals
Biohybrid robots are on the rise and for good reason. They could help millions of people. There are already biohybrid robots that help people talk, walk, and in the future, see. The integration of AI has helped boost this industry. Now, VIPS-3D could help make these items lighter, which would improve battery life and portability.
Aerospace
The aerospace industry is another area where porous 3D printing methods thrive. Pourosness is crucial when reducing weight and when discussing aerospace, weight is always a focus. The new method could streamline the creation of lightweight aerospace products on the go.
These 3D printers could one day be used to create replacement parts for a spacecraft. The ability to customize material usage and integrate polymers and metals makes it the ideal solution for these scenarios.
