Developed by researchers at the University of California, Berkeley, Rochester, and MIT, this latest technology replaces layering with stereo printing while creating entire objects. This is achieved by illuminating a plastic resin-filled hologram-shaped transparent water tank with three overlapping green laser pointer.
A single beam of light for a short time is not enough to cure the resin in a short time, but combining three lasers can cause curing in about ten seconds. After the object is formed, excess resin is discharged to display the entire unit. In fact, you can complete 3D parts in one step, which does overcome an important issue in additive manufacturing.
We are trying to print a 3D shape at the same time, and the real purpose of this paper is to ask, ‘Can we complete any 3D shape at once instead of putting the parts together layer by layer? ‘It turns out we can. Stereoscopic printing is not only faster and more flexible, but also does not require temporary support structures, and even provides more Green Laser Pointer geometric flexibility.
