1. A process for applying a particle material to a assembly platform for the creation of a three dimensional rapid prototype, comprising the steps of:
- a. applying the particle material to the assembly platform, for the creation of a three dimensional rapid prototype by a layer by layer deposition method, in advance of a moving blade that is mounted on an end of an arm;
b. moving the blade, the blade including;
1) a front edge and2) a rear edge essentially aligned vertically with respect to the front edge, the edges facing a surface to be coated rounded by radii,wherein the moving blade creates a zone that includes;
1) a homogenization zone in front of the blade,2) a compression zone between the front radius of the blade and the assembly platform, and3) a smoothing zone between the front and rear radii of the blade and the assembly platform;
c. vibrating the blade in an oscillating rotary motion about an axis in which the blade is rotatably mounted,wherein the vibration of the blade causing the particles to be fluidized and creating a roll of the particles in front of the blade, further wherein a proportion of the particle material is drawn through the compression zone during the movement over the assembly platform and during reversal of the blade providing an even layer of particle material on the assembly platform;
d. passing the blade over the assembly platform;
e. lowering the assembly platform; and
f. repeating steps a-e until the three dimensional rapid prototype is complete.

Abstract
The invention relates to a method for applying fluids, especially particle material, on a area that is to be coated, wherein the fluid is applied on the area to be coated in front of a blade when observed from the direction of forward movement of the blade and said blade is then displaced on the applied fluid. The method is characterized in that the blade performs an oscillation similar to a rotational movement.

-
a. applying the particle material to the assembly platform, for the creation of a three dimensional rapid prototype by a layer by layer deposition method, in advance of a moving blade; b. providing a moving blade mounted on an arm, the moving blade including; 1) a front edge and 2) a rear edge essentially aligned vertically with respect to the front edge, the edges facing a surface to be coated rounded by radii, wherein the moving blade creates a zone that includes; 1) a homogenization zone in front of the blade, 2) a compression zone between the front radius of the blade and the assembly platform, and 3) a smoothing zone between the front and rear radii of the blade and the assembly platform; c. advancing the moving blade across the assembly platform; d. swinging the blade forward, in a rotary motion, about an axis in which the blade is rotatably mounted, wherein the swinging of the blade causes the particles to be fluidized; e. creating a roll of the particles in the homogenization zone by the rotary motion of the blade and a forward movement of the blade across the assembly platform; f. swinging the blade backwards in a rotary motion about the axis; g. drawing a proportion of the particle material from the roll through a gap formed between at least one of the radii of the blade and a surface of the assembly platform to be coated; h. compressing and applying the particle material to the surface of the assembly platform to be coated in the compression zone; i. smoothing the particles in the smoothing zone during both the forward and backwards swinging steps providing an even layer of particle material on the assembly platform; j. lowering the assembly platform; and k. repeating steps a-j until the three dimensional rapid prototype is complete. - View Dependent Claims (11)
