Process and device for producing a three-dimensional object

A preparation process for preparing a production process of at least one three-dimensional object by solidifying a solidifyable material, said prepared production process being of a type comprising:

• providing an object carrier capable of carrying the object to be produced;
• bringing a solidifyable material carrier/provider in a position to provide solidifyable material at least in a building region where solidifyable material is to be solidified;
• and
• supplying, to the building region, energy capable of solidifying the solidifyable material;
• wherein said preparation process includes the step of:
• providing build data which, when executed, allow to produce the at least one three-dimensional object;
• and
• nominally setting process parameters on the basis of said build data,
• wherein said process parameters are nominally set, depending on at least one of:
• a structure of said at least one three-dimensional object to be produced;
• a presence or absence or a structure of an auxiliary support;
• type of solidifyable material and composition of solidifyable material;
• adhesion of solidifyable material to solidifayable material carrier/provider;
• and
• adhesion of solidifyable material to a previously solidified layer and/or cross-section and/or voxel matrix of previously solidified material;
• to control at least one of the following parameters:
• (a) moving distance between the object carrier and the building region, or between the object carrier and a surface of said solidifyable material carrier/provider, before providing energy for solidification;
• (b) pressure force of either the object carrier or the solidifyable material carrier/provider, respectively, towards the building region;
• (c) degree of insertion of object carrier, optionally having previously solidified material thereon, into solidifyable material provided;
• (d) separation force of either the object carrier or the solidifyable material carrier/provider, respectively, from the building region;
• (e) fluid pressure in or at the building region;
• (f) moving speed of said object carrier or said solidifyable material carrier/provider, respectively, in a direction towards or in a direction away from the building region;
• (g) tensile load of said solidifyable material carrier/provider;
• (h) coplanarity or tilt angle between a surface of said object carrier and a surface of said solidifyable material carrier/provider;
• and
• (i) rolling away or gliding away of the solidifyable material carrier/provider from a build area.

A process for producing at least one three-dimensional object by solidifying a solidifyable material, comprising the steps of:

• providing an object carrier capable of carrying the object to be produced;
• providing a material capable of solidifying when subjected to energy supply;
• bringing a solidifyable material carrier/provider in a position to carry/provide solidifyable material at least in a building region where solidifyable material is to be solidified;
• supplying, to the building region, energy capable of solidifying the solidifyable material;
• wherein a contact pressure of said object carrier, or of solidified material formed thereon through previous solidification, towards a surface of said solidifyable material or said solidifyable material carrier/provider occurring in or at the building region is sensed and/or adjusted.

• supplying, to the building region, energy capable of solidifying the solidifyable material;
• wherein a fluid pressure and/or a flowability of solidifyable material occurring in or at the building region or in or at the solidifyable material carrier/provider is sensed and/or adjusted.

A device for producing at least one three-dimensional object by solidifying a solidifyable material, comprising:

• a device for supply of energy to a building region, the energy supply device being capable of solidifying the solidifyable material;
