## Abstract

A tangible structure includes a set of removable and parallel rods, each rod including a head; a set of drive devices, each drive device including a motor element generating a rotational motion to a transverse shaft to transmit a translational motion to a rod, the drive device being piloted in order to transmit a motion to the rod at a given speed and in a given direction; a holding system for the drive devices making the drive devices integral with each other, and a calculator determining a set of pilot set points, each pilot set point being transmitted to a drive device on the basis of a first digital set point.

## Claims

### Claim 1

A tangible structure, comprising:
a set of movable and parallel rods, each rod including a head;
a set of drive devices, each drive device including a motor element generating a rotational movement to a transverse shaft to transmit a translational motion to a rod, said drive device being piloted in order to transmit a motion to the rod at a given speed and in a given direction;
a holding system for the drive devices making said drive devices integral with each other;
a calculator arranged to determine a set of pilot set points, each pilot set point being transmitted to a drive device on the basis of a first digital set point.

### Claim 2 (depends on 1)

The tangible structure according to claim 1, wherein each drive device comprises a pressure element driven by the motor element in turn driving a rod by friction.

### Claim 3 (depends on 1)

The tangible structure according to claim 1, wherein each drive device comprises a bevel gear system including two gear wheels allowing transmission of the rotation of the drive shaft to a rotation of a transverse shaft, said rotation of the transverse shaft causing rotation of the roller, said roller being secured to the transverse shaft.

### Claim 4 (depends on 1)

The tangible structure according to claim 1, wherein the rods are made of a polymeric material.

### Claim 5 (depends on 1)

The tangible structure according to claim 1, wherein each drive device is integrated into a frame of substantially parallelepipedal shape and including two guides each including an opening adapted to receive a rod in order to direct translational motions of a rod, said rod passing through said frame.

### Claim 6 (depends on 1)

The tangible structure according to claim 1, wherein the rods are provided at their ends with an elastic head formed by a material among which: {elastomer, polymer, resin}.

### Claim 7 (depends on 1)

The tangible structure according to claim 1, comprising a deformable surface, the deformation of which is driven by the rods, each of the heads of which is in contact with said surface.

### Claim 8 (depends on 1)

The tangible structure according to claim 1, wherein:
the holding system is a plate including a plurality of openings, each opening allowing a rod to pass therethrough,
and wherein the tangible structure includes a second guide plate having a plurality of openings and parallel to the first plate and spaced apart by a predefined distance for sandwiching the drive devices, said second plate being arranged such that each rod passes through both plates.

### Claim 9 (depends on 1)

The tangible structure according to claim 1, further comprising a plurality of light sources, said light sources being controlled by a light set point, each of the light sources being arranged:
at one end of a head of a rod, or;
in a thickness of a deformable surface,
the calculator coordinating generation of the pilot set point with generation of the light set point from a same first digital set point.

### Claim 10 (depends on 1)

The tangible structure according to claim 1, further comprising a heating source and a means for activating heat to be applied to a material arranged in contact with the ends of the rods.

### Claim 11 (depends on 1)

The tangible structure according to claim 1, wherein the first digital set point is:
at least one digital piece of data;
pixel values of a digital image and/or a pixel distribution of said image;
digital information including text and/or numbers.

### Claim 12 (depends on 10)

A method for manufacturing a three-dimensional object, comprising:
positioning and holding a thermosetting material on a structure according to claim 10;
activating the tangible structure by a rod pilot set point in order to form a three-dimensional shape deforming the thermosetting material held at the end of each rod;
activating a source of heating of the thermosetting material beyond a predefined temperature threshold allowing the thermosetting material to polymerize, and
cooling and removing the material.

### Claim 13

A method for generating a three-dimensional shape by activating a plurality of rods of a tangible structure, said rods being arranged in parallel to each other, said method comprising:
receiving an image made by a communication interface or a memory of the structure;
calculating a plurality of stroke indicators for a plurality of sets of pixels of the image, each stroke indicator being calculated for a given rod of the structure depending on the properties of each set of pixels;
guiding the set of rods by means of each drive device, said drive devices each generating a motor set point from a pilot set point deduced from the stroke indicators, each pilot set point further generating an electrical set point each piloting a light source arranged at the end of each rod and activating a property of the light emitted by each of them.

### Claim 14 (depends on 1)

The tangible structure according to claim 1, wherein the pressure element is a roller.
