摘要： A three-dimensional (3D) printing build material composition includes polyamide particles and a filler material consisting of aramid fibers having an aspect ratio ranging from about 0.1 mm/20 μm to about 1.2 mm/16 μm. The polyamide particles are present in an amount of at least 82 wt % based on a total weight of the build material composition, and the aramid fibers are present in an amount ranging from about 2 wt % to about 18 wt % based on the total weight of the build material composition.

摘要： An example image forming apparatus that detects an error of an image formed on a printing medium, the apparatus includes a print engine, an inline scanner located at an output end of the print engine, and a processor. The processor is to obtain information of print data of a received print job, form an image on a printing medium based on the print data by using the print engine, obtain information of a print image of the printing medium on which the image is formed by using the inline scanner, detect whether normal output is performed by comparing the information of the print data with the information of the print image, and, in a case where the normal output is not detected, detect an output error and perform re-output.

摘要： An example system includes a first image sensor, a second image sensor, and an electronic device. The electronic device includes a controller that is to compare positions of a human face and a non-human object in a first set of images captured by the first image sensor. In addition, the controller is to select a presentation arrangement of the first set of images and a second set of images captured by the second image sensor based on the comparison. Further, the controller is to output the first set of images and the second set of images to a video conferencing application in the selected presentation arrangement.

摘要： A device to prevent fire of a fusing belt having a heater positioned inside includes at least one temperature control member adjacent to one side of the fusing belt and, when the at least one temperature control member detects abnormal heat from the fusing belt based on a temperature of the fusing belt, the at least one temperature control member to cut off a supply of electricity to the heater to prevent the fire. The device also includes a heat absorption member adjacent to the other side of the fusing belt and to absorb latent heat from the fusing belt to lower the temperature of the fusing belt to prevent the fire.

摘要： A method of three-dimensional printing can include iteratively applying a polymer build material as individual layers to a powder bed, where the polymer build material includes from about 80 wt % to 100 wt % polymeric particles, and based on a three-dimensional object model, selectively applying a coalescing agent onto individual layers of the polymer build material. The coalescing agent can include an aqueous liquid vehicle and a coalescing solvent that depresses a melting point of the polymeric particles. The method can include exposing the powder bed to heat to selectively coalesce portions of individual layers of the polymer build material in contact with the coalescing solvent. The heat may not be sufficient to coalesce the polymer build material that is not in contact with the coalescing solvent and may be sufficient to fuse the polymeric particles in contact with the coalescing solvent together to form a three-dimensional object.

摘要： The present disclosure is drawn to bio-ink printer components, methods of printing bio-inks, and multi-fluid live cell printing systems. In one example, a bio-ink printer component can include a bio-ink and a bio-ink ejector fluidly connected or connectable to the bio-ink. The bio-ink can include a buffer solution that is suitable for live cells, and a polymer that includes polyvinylpyrrolidone, polyvinyl alcohol, polyvinyl sulfate, polyethylene glycol, polyester, poly(dimethylsiloxane), cellulose, polysaccharide, or a combination thereof. The bio-ink ejector can include an ejection nozzle and a thermal resistor positioned to heat the bio-ink to form a vapor bubble to eject a droplet of bio-ink from the ejection nozzle.

摘要： Examples include apparatuses, processes, and methods for generating three-dimensional objects. An example apparatus comprises build material distributor and a controller. Examples distribute a particular build layer in a build area of the apparatus over a previous build layer. Examples determine a build layer temperature corresponding to the particular build layer. Examples analyze build layer coverage for the particular build layer based at least in part on a build layer temperature of the previous build layer and the build layer temperature of the particular build layer. Examples selectively recoat the particular build layer with additional build material based at least in part on the build layer coverage for the particular build layer.

摘要： A three-dimensional printing kit, as presented herein, can include a particulate build material and a binder agent. The particulate build material can include from about 80 wt % to 100 wt % metal particles based on the total weight of the particulate build material. The binder agent can include an aqueous liquid vehicle, an acrylic polymer or copolymer latex dispersion, a sulfonated small-molecule dispersed pigment, and a solubilized dihydrazide. A sulfonated small-molecule of the sulfonated small-molecule dispersed pigment can be from about 100 g/mol to about 2000 g/mol. The binder agent can exclude a polymeric dispersant.
