Abstract: In some examples, an interaction module of a three-dimensional (3D) printer can include an interaction sub-module including a coupler, where the coupler is to connect to a tool, a first actuator to move the coupler in a first direction, and a second actuator to move the coupler in a second direction, and an analytics system to analyze the coupler and the tool during an interaction with a 3D object of the 3D printer, where the tool of the coupler is to interact with the 3D object of the 3D printer during a 3D print job.

Abstract: The present disclosure is drawn to coalescent inks and material sets, such as for 3D printing. In one example, the coalescent ink can include a conjugated polymer, a colorant imparting a visible color to the coalescent ink, and an ink vehicle comprising a high boiling point co-solvent having a boiling point of 250° C. or greater. The high boiling point co-solvent can be present in an amount from about 1 wt % to about 4 wt % with respect to the coalescent ink.

Abstract: In an example, a composition for three-dimensional (3D) printing includes a polymer build material and a non-conductive fusing agent dispensable onto the polymer build material to form a polymer-fusing agent composite portion when heated to a sintering temperature, a conductive agent dispensable onto on the polymer build material to form a polymer-conductive agent composite portion when heated at least to the sintering temperature, the conductive agent comprising: at least one conductive particulate present in an amount of from about 10% to about 60% of a total weight of the conductive agent; at least one co-solvent present in an amount of from about 10% to about 50% of a total weight of the conductive agent; and an additive present in an amount of from about 0% to about 10% of a total weight of the conductive agent.

Abstract: Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.

Abstract: A three-dimensional printing system can include polymeric build material and jettable fluid(s). The polymeric build material can have an average particle size from 20 μm to 150 μm, a first melt viscosity, and a melting temperature from 75° C. to 350° C. In one example, the jettable fluid can include water, from 0.1 wt % to 10 wt % of electromagnetic radiation absorber, and from 10 wt % to 35 wt % of an organic solvent plasticizer. Contacting a first portion of a layer of the polymeric build material with the jettable fluid can provide an organic solvent plasticizer loading from 2 wt % to 10 wt % based on the polymeric build material content. The first melt viscosity of the polymeric build material at the first portion can be reduced and the melting temperature of the polymeric build material at the first portion can be decreased by 3° C. to 15° C.

Abstract: Example described herein include a three-dimensional printer a threedimensional printing device that includes a fusible material applicator to apply a layer of fusible material, a inhibiting material applicator to apply a patterned layer of inhibiting material to establish exposed regions of the layer of fusible material and blocked regions of the layer of fusible material based on information corresponding to a three-dimensional model, and a photonic energy emitter to apply photonic energy to fuse the exposed regions of the layer of fusible material.
