Title: **Innovations of Erjian Ma: Pioneering 3-D Fabrication**
Introduction
Erjian Ma, based in Auburn, AL, is a distinguished inventor known for his significant contributions to the field of three-dimensional (3-D) fabrication. With a total of four patents to his name, Ma has been pivotal in advancing technologies that revolutionize how 3-D objects are created and manipulated.
Latest Patents
Among his latest inventions, Erjian Ma holds patents for two notable methods that enhance the fabrication of 3-D objects.
The first is the **Layer-additive method and apparatus for freeform fabrication of 3-D objects**. This innovative approach involves fabricating a 3-D object using porous solid preform layers and a pore-filling material. The method includes a series of steps: providing a work surface, feeding and dispensing materials onto he preform layers, stacking layers in the Z-direction, and ultimately forming a unitary body by affixing the layers together. A crucial part of this process is the removal of support structures by exposing un-hardened areas to a support-collapsing environment, leading to the final 3-D object.
The second patent, titled **Rapid prototyping and tooling system**, describes a solid freeform fabrication process that utilizes a material deposition sub-system to deposit solidifiable liquid compositions onto a work surface. The method emphasizes precision by controlling the focus of heat and creating a weld pool of molten materials, which solidify to form individual layers of the object. This technique allows for enhanced accuracy and the construction of complex shapes through a controlled layering process.
