IBM files patent application for novel hologram 3D printer

IBM has patented the concept for a hologram 3D printer. The engineers at IBM are working with an acoustic hologram that is generated with sound waves in the 3D printing sector. The objects generated in this way should feel like real objects in the room.

IBM has now published the patent with the name "3d printing on the surface of an acoustic hologram". The company had already successfully filed its patent application in June 2017. In February 2017, the Californian company DAQRI also introduced a hologram 3D printer:

 

 

IBM works with an acoustic hologram that is generated with sound waves in the 3D printing sector. In one step, hollow objects are to be printed. The hologram consists of acoustic waves that generate invisible acoustic radiation forces in 3D space and feel like surfaces of a solid object. Brigham Young University succeeded in 3D projection of volumetric images in January 2018.

 

 

The resulting hologram of the patented IBM 3D printer creates a tactile illusion of an object floating in space within a 3D printing area. When a 3D printing medium is applied to the surface of the hologram, the medium solidifies on the hologram surface. The result is a hollow envelope in the form of the object to be printed. The patent for the hologram 3D printer was granted patent number US20180361680A1 and was filed on June 19, 2017

UC Berkley introduced a new DLP technology

Posted on: Mon, 02/04/2019 - 14:54 By: Blacksheep

UC Berkley introduced a new 3D printer technology which uses light to transform sirupy liquids into solid objects in only a matter of minutes.

Quote from the article

Most 3D printers, including other light-based techniques, build up 3D objects layer by layer.  This leads to a “stair-step” effect along the edges. They also have difficulties creating flexible objects because bendable materials could deform during the printing process, and supports are required to print objects of certain shapes, like arches.

The new printer relies on a viscous liquid that reacts to form a solid when exposed to a certain threshold of light. Projecting carefully crafted patterns of light — essentially “movies” — onto a rotating cylinder of liquid solidifies the desired shape “all at once.”

Welcome to the open-SLA.org community!

As the Google+ services are being shut down soon in April hereby I will provide a platform as a possible replacement. So many member have been discussed what's next and how to keep the openSLA community alive. So I have created this website for you to test.

The setup is very rudimentary and if this site is being accepted by the community I am willing to extend the site with more possibilitys, e.g. a community addon. Feel free to provide your feedback in the forum.
