Anti-gravity Object Modeling
MATAERIAL is a patent-pending new method of additive manufacturing which allows for creating 3D objects on any given working surface independently of its inclination and smoothness, without a need of additional support structures.
Conventional methods of additive manufacturing are affected both by gravity and by printing environment. By using innovative extrusion technology Mataerial team is able to neutralize the effect of gravity during the course of the printing process.
This method gives the flexibility to create truly natural objects by making 3D curves instead of 2D layers. Unlike 2D layers that are ignorant to the structure of the object, the 3D curves can follow exact stress lines of a custom shape. Their new out of the box printing method can help manufacture structures of almost any size and shape.

Gel dispensed printing (GDP)
An Israeli company has recently created a 3D printing technology specifically suited for large objects that usually require supports to help stabilize complex overhangs or angles. GDP printer uses a moving gantry system to cure UV sensitive material with light. Once UV light hits a specific area, the gel cures and solidifies into a hard polymer. Using a combination of proprietary software, special printing gel, and UV curing processes, the MASSIVIT 3D printer can create non-vertical walls and ceiling without the need for supports.
