A three-dimensional printing system includes a print bed and a shelf insertion mechanism for inserting a shelf of one or a plurality of auxiliary shelves into a print volume between the print bed and a printer head. A printer assembly is configured to deposit layers of material within the print volume to form one or more objects on a support platform, the support platform including the print bed or an auxiliary shelf that is inserted into the print volume by the shelf insertion mechanism. A controller is configured to control the shelf insertion mechanism to insert an auxiliary shelf between the print bed and a printer head of the system after formation of the objects on that support platform by the printer assembly is complete.

A method for the additive manufacturing of an elastomer part, includes—the creation of a model of spatial coordinates of the part; followed by—the corresponding deposition of an elastomer material. The deposition is carried out in a plurality of substantially flat layers which are vertically stacked. The elastomer material is deposited in the form of a latex-based liquid composition having a dispersion of polymers in an aqueous base, and the deposition is carried out by formation and pressurized ejection of drops of a liquid composition.

Systems and a method determine an amount of printing material powder for 3D printing an object a multi-object printing job. Data on the following is received: a 3D-model of the object, a volume and a surface of the object, data on a thickness of a powder, on characteristics of the build chamber, a volume of a no build zone and a volume of a net build zone, an estimation of a volume of recyclable interstitial powder, on a powder density and on a solid density of the printing material and on a recycling ratio. The following quantities are determined: a volume of the powder layer around the object, a dilated object contribution, the amount of used powder due the dilated object, the amount of lost powder in the no build zone, the amount of lost powder in the net build zone and the amount of printing material required.
