The 3D printer systems can also assist other production methods. The 3D printing system. It can be used. To create the models for casting molds. The regular system prints material layer by layer. In regular casting technology. The 3D printer makes the object. And then the ceramic mold will be made around that thing. 

The new hologram-based printing system can make 3D printing even more accurate and effective. The growth of efficiency. It is about 70%. The system turns the hologram straight into a physical object. ScitechDaily describes this system like this. 

“The technology, known as tomographic volumetric additive manufacturing (TVAM), works more like a CT scan in reverse than a traditional 3D printer. Instead of stacking material one layer at a time. The TVAM system projects patterns of light. Into a rotating vial filled with photosensitive resin. Wherever enough light energy accumulates, the liquid rapidly solidifies into a complete 3D structure”. (ScitechDaily, New Holographic 3D Printing Method Is 70x More Efficient)

"During testing, the team produced millimeter-scale objects in seconds and centimeter-scale objects within minutes. The phase-controlled system also supports self-healing beams, allowing the printer to create more accurate structures in materials that scatter light, including those containing living cells." (ScitechDaily, New Holographic 3D Printing Method Is 70x More Efficient)

But the ability to use so-called.  Cold photo-reacting resin allows the system to drive living cells into the form. That operators want. The resin can carry living cells into the form. That. The operators want. And that thing could make it possible to create the organs and even limbs. 

And maybe in the future, that kind of system. They can make it possible to clone entire humans. In some futuristic visions, this kind of system can make interstellar voyages possible. The interstellar spacecraft carries. The humans whose genetic code is stored in a digital form. When that craft is close enough. The destination. The printer system transforms those digital creatures into a physical form. It creates cells and DNA that can be used to turn the digital model into a physical human. 

The resin could act as a mold. Those things. Like tissue printing systems can use. These kinds of systems. They can also. Make it possible to create more accurate molds and models for the regular metal-based 3D printers. 

The photosensitive resin can be used to create a test piece. That is used. For fitting the real pieces into the entirety, like machines. The photosensitive resin can also act. As the mold for the casting mold. The ceramic mold will be cast around those pieces. And this brings new accuracy for those systems. Even if some systems are made for some particular functions. There is also a possibility. To use those systems also for other purposes.
