CPC Class B33Y

A system for building a structure. The system includes a reservoir; an immiscible fluid in the reservoir; a membrane operatively connected to the reservoir; channels and delivery ports in the membrane; a microliter amount of curable resin; a delivery system for delivering the microliter amount of curable resin to channels and delivery ports in the membrane and to the reservoir in contact with the immiscible fluid in the reservoir; and an energy source adapted to deliver energy to the reservoir onto the microliter amount of curable resin for building the structure.

A three-dimensional (3D) continuous color printer includes one or more cartridges each with a building material stored therein, a mixer coupled to each cartridge, and a single printhead coupled to a mixer output, wherein the building material stored in the cartridge is transported to the mixer and the single print head to form a continuous color object.

The invention relates to a method for manufacturing road surface covering elements that can be mounted on rollers of chassis dynamometers, including detection of a surface contour of a road surface covering within an essentially strip-shaped section. The method also includes production of a digital image of the detected section and manufacturing of the road surface covering element according to the digital image by means of a three-dimensional manufacturing technique.
