Abstract

In a three-dimensional (3D) printing method example, a metallic build material is applied. A binder fluid is selectively applied on at least a portion of the metallic build material. The binder fluid includes a liquid vehicle and polymer particles dispersed in the liquid vehicle. The application of the metallic build material and the selective application of the binder fluid are repeated to create a patterned green part. The patterned green part is heated to at about a melting point of the polymer particles to activate the binder fluid and create a cured green part. The cured green part is heated to a thermal decomposition temperature of the polymer particles to create an at least substantially polymer-free gray part. The at least substantially polymer-free gray part is heated to a sintering temperature to form a metallic part.

Abstract

A method and system for a three dimensional printing system are described herein. In one example, the three dimensional printing system has a moveable carriage, an array of laser modules and a print controller. In this example, the moveable carriage has a print head arranged to selectively deposit a printing agent on to a layer of build material as the moveable carriage is moved relative to the layer of build material. The printing agent controls localized fusing of the build material on application of energy. The print controller is communicatively coupled to the array of laser modules and controls activation of individual laser modules of the array of laser modules so as to apply, selectively, energy to addressable sub-regions of the layer of build material on which printing agent has been deposited to control fusing together with the deposited printing agent.

Each cooling fin of the set is positioned to form a gap between that cooling fin and an adjacent cooling fin. The gas flow inlet is to receive the subject gas. The combination of the gap between each cooling fin of the set and the cooling capacity of the cooling fluid pathway is sufficient to, if the subject gas has ignited, lower temperature of the subject gas to below autoignition temperature.

Abstract

The present disclosure provides methods of three-dimensional printing, including iteratively applying individual build material layers of polymer particles having a D50 particle size from about 20 µm to about 150 µm to a build material, and based on a three-dimensional object model, selectively applying a fusing agent onto the individual build material layers to form individually patterned object layers of the three-dimensional object and selectively applying a pore-promoting agent onto the individual build material layers at a discrete location of the individually patterned object layers to form a pore-generating region therein. The method also includes exposing the build material to electromagnetic energy to provide selective heat fusing of the polymer particles and to generate and displace molten polymer leaving a localized void having a void size from about 1 mm to about 20 mm.

Abstract

Object model data modification is described in which object model data defining a three dimensional model to be generated by a three-dimensional printer may be obtained. Data relating to a first sensitive portion of the model may be obtained, the first sensitive portion representing a portion of the model to be concealed. Modified object model data in generated, the modified object model data including a first version of the three dimensional model that is represented in a first pre-processing application without exposing the first sensitive portion, and including the first object model data defining the three dimensional model for printing by a three-dimensional printer.

Abstract

Three-dimensional printing kits can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer build particles and cellulose particles. The cellulose particles can be chemically and thermally stable at a melting point temperature of the polymer build particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.

Abstract

Three-dimensional printing can include iteratively applying build material layers including stainless steel particles, iteratively applying a binding agent to individual build material layers to define individually patterned object layers that become adhered to one another to form a layered green body object, and sintering the layered green body object in a sintering oven. The stainless steel particles can include from about (2) wt % to about (6) wt % nickel, from about (14) wt % to about (19) wt % chromium, from about (2) wt % to about (6) wt % copper, and up to about (700) ppm carbon. Sintering can include ramping up the temperature to about (1240)° C. to about (1320)° C., pausing for about (30) minutes to about (12) hours, and ramping up the temperature to about (1350)° C. to about (1400)° C. for (10) minutes to about (6) hours.

Abstract

This disclosure describes three-dimensional printing kits, methods, and systems for three-dimensional printing with phosphorescent pigments. In one example, a three-dimensional printing kit can include a powder bed material and a low-tint fusing agent. The powder bed material can include polymer particles and phosphorescent pigment particles mixed with the polymer particles. The low-tint fusing agent can include water and an electromagnetic radiation absorber. The electromagnetic radiation absorber can absorb radiation energy and convert the absorbed radiation energy to heat.
