Definitions
- the present invention relates to a new cement composition for 3D printing and a 3D printing process using said cement composition.
- 3D printing or three-dimensional printing refers to the processes for manufacturing parts in volume by adding or agglomerating material. In the industrial environment it is also designated by the term additive manufacturing.
- manufacture of the object slice by slice via the execution of the G-code by the machine which deposits or solidifies the material layer by layer until obtaining the final part.
- the principle remains close to that of a conventional 2D printer except that the stacking of layers makes it possible to create volume.
- the plastic filament is heated at the level of the print head which allows its extrusion then hardens very quickly after being applied;
- laser sintering essentially used for printing metal: a laser strikes a metal powder locally generating cohesion between the powder particles and the formation of a metal structure by sintering.
- 3D printing from cementitious materials to design structures more efficiently is also booming.
- the printing process used is similar to the process used for plastics, except that extrusion and hardening are not ensured by heating at the print head.
- the material in the fluid state is pumped up to a print head where it undergoes a sudden change in its rheology which allows it to be extruded into a bead of material which does not sag and supports its own weight.
- the cement ink is prepared upstream of the printer in a mixer. It can be prepared by batch or via a continuous process. It is then pumped to the print head.
- the ink is mixed with an adjuvant suddenly accelerating its setting.
- This mixing or stirring can be done using two technologies: the static mixer: it is a tube inside which numerous obstacles disturb the flow of ink. The turbulence thus generated makes it possible to homogenize the various constituents of the ink before extrusion; or
- the dynamic mixer consisting of a propeller (rotor) rotating in a tube (stator) and actuated by a motor. This is the most effective brewing technique.
- the ink is extruded through a nozzle into a bead of material of dimension defined by the flow of material and the speed of movement of the print head, allowing the printing of the following structure the G-Code.
- a cement ink must therefore meet three main requirements:
- composition directly after its preparation, the composition must be sufficiently fluid to be pumpable but not to segregate (so-called “pumpability” criterion);
- the composition must be capable of undergoing a sudden change in the rheology in order to make it much more viscous and allow the mortar bead not to spread out after extrusion; and finally, after passing through the print head, the cords already extruded / printed must have sufficient strength to hold the weight of the new extruded layer (the so-called "buildability" criterion).
- cement inks containing essentially a Portland binder have been used.
- Portland cement is used in the form of a suspension in water.
- hydration begins to harden the cement, which is not without posing difficulties in the 3D printing process, the rise in resistance of the ink thus prepared is slow, which limits the printing speed.
- Chinese patent application CN 104 310 918 describes a cement ink for 3D printing comprising one or two cements, in particular a mixture of sulfoaluminous cement of Portland cement, as well as optionally a filler chosen from fly ash, slag powder, silica fume, activated gangue or blast furnace slag. Again, the rise in resistance of the ink thus prepared is slow or even insufficient, which limits the printing speed or makes it impossible.
- compositions comprising one or more cements makes it possible to obtain cement inks.
- a silicoaluminous filler having a specific surface of at least 5 m 2 / g makes it possible to obtain cement inks. having particular rheological properties, in particular a high threshold which, coupled with a high reactivity and a very rapid rise in resistance or more controlled as required thus allows faster printing and at least equivalent quality.
- the subject of the present invention is a cement composition for 3D printing comprising:
- the cement composition according to the present invention has a high reactivity, a very rapid or more controlled increase in resistance depending on the proportions of Portland cement, aluminous cement, sulfoaluminous cement and / or natural cement which is prompt in the composition.
- a silicoaluminous filler having a specific surface of at least 5 m 2 / g makes it possible to significantly increase the printing speed (in particular by the generation of a threshold essential to the behavior of the printed structure ) while maintaining or even improving the quality thereof.
- cement composition for 3D printing means any composition of cement, mortar or concrete which, after adding water, is capable of being used as ink in 3D printing;
- - "Portland cement” means any Portland clinker cement classified as CEM (I, II, III, IV or V) according to standard NF EN 197-1;

- Example 1 Cement ink containing a single cement 1.1 - Composition
- E-1 An ink for 3D printing (E-1), the characteristics of which are reported in Table 1 below, was prepared from a “monocomponent” cement ink.
- the E-1 ink was prepared in a laboratory mixer according to the following procedure: - dry mixing for 45s of all of the dry constituents to homogenize the mixture;
- Table 3 Resistance to El ink compression The resistances observed are compatible with the use of El ink in 3D printing.
- Example 2 One-component cement ink
- E-2 An ink for 3D printing (E-2), the characteristics of which are reported in Table 4 below, was prepared from a “one-component” cement ink.
- the E-2 ink was prepared in a laboratory mixer according to the following procedure: dry mixing for 45s of all the dry constituents to homogenize the mixture;
- the inks E-3 and E-4 were prepared in the laboratory in a mixer according to the following procedure:
- lithium carbonate has a very moderate effect on the increase in resistance of Portland cement considered alone and it does not or very little disturb its rheology.
- the binder formed consists of Aveat R 2 and Portland cement CEM I in proportions 60/40, a formula which sets in a few seconds, and the lithium carbonate then accelerates the increase in resistance of the mixture.
- This “cross-additive” allows the introduction of additives having a powerful effect on one component (A) via the other component (B), their effect only being triggered when the two constituents meet.
- Each component of the ink was prepared separately. The dry materials were mixed for 45 seconds at low speed and then the water was added for 15 seconds. The cement paste is then mixed for one minute at low speed.
- the two components were then introduced into syringes connected to a static mixer in which they are brought into contact. At the outlet of this mixer, the mixture of the two components has set and the material has passed from the state of liquid to that of thick paste in a few seconds without the need to add liquid adjuvants such as a superplasticizer or a catch trigger.
- liquid adjuvants such as a superplasticizer or a catch trigger.
- the inks E-6 to E-9 were prepared in the laboratory in a mixer according to the following procedure:
- the indicated amount of setting trigger (Chryso Jet 1000 AF) is then added and the ink is mixed again for 30 seconds.
- Layers of material are then stacked successively in order to validate the criterion of "buildability" or the ability of the ink to support its own weight and that of the successive layers.
- a cylindrical cookie cutter 40mm in diameter and 30mm high is used.
- Successive layers are added at a rate of 1 layer every 30 seconds. This test makes it possible to study the behavior of the first layer deposited when the load applied to it increases.
- the inks E-6 and E-8 (which contain a silicoaluminous filler) allow a stacking of layers up to at least 20 successive layers without observing deformation or sagging of the lower layer.
