Devices, systems, and methods are directed to the use of nanoparticles for improving strength fabrication of three-dimensional objects formed through layer-by-layer process in which an ink is delivery of a binder delivered onto successive layers of a powder of inorganic particles in a powder bed. More specifically, nanoparticles of inorganic material can may be introduced into one or more layers of the metal powder in the powder bed and thermally processed to facilitate sinter necking, in the powder bed, of the metal particles forming the three-dimensional object. Such sinter necking in the powder bed can may improve strength of the three-dimensional objects being fabricated and, also or instead, can may reduce the likelihood of defects associated with subsequent processing of the three-dimensional objects (e.g., slumping and shrinking in a final sintering stage and/or inadequate densification of the final part).

An object of the present invention is to provide a nonaqueous primer composition offering excellent discharge property and adhesion to printing media, even when applied on roll materials (acrylic, PET, etc.), board materials (glass, plastics, etc.), and other nonabsorbent media. As a solution, a nonaqueous primer composition containing a chlorinated polyolefin resin and a ketone resin is provided, wherein the chlorinated polyolefin resin and ketone resin together account for at least 10 percent by mass in the primer composition, the chlorine content in the chlorinated polyolefin resin is 30 to 50 percent by mass, and the chlorinated polyolefin resin and ketone resin are contained at a ratio by mass, calculated by “Chlorinated polyolefin resin/Ketone resin,” of 3/7 to 7/3.

A method of fused filament fabrication (FFF) additive manufacturing comprises employing a thermoplastic blend comprised of high density polyethylene and a second thermoplastic polymer, wherein the second polymer is a low density polyethylene (LDPE), functionalized polyolefin or combination thereof and the amount of high density polyethylene to the amount of second thermoplastic polymer by weight is a ratio from 1.5/1 to 20/1. LDPE means a polyethylene that have been radically polymerized at high pressure. The method allows for the additive manufacturing article that retains the desirable mechanical properties of HDPE without experiencing the problems inherent in FFF printing of HDPE or use of solid fillers. In a particular embodiment, the additive manufactured article has a continuous phase and the second thermoplastic polymer is present as a discontinuous phase within the additive article manufactured article and the filament used to make the article.

An example of an anti-coalescing agent for a three-dimensional (3D) printing process includes a vehicle and an anti-coalescing polymer dispersed in the vehicle. The vehicle includes a co-solvent, a surfactant, a humectant, and water. The anti-coalescing polymer has a mean particle size ranging from about 50 nm to about 195 nm, and the anti-coalescing polymer is to coat polymeric build material particles to prevent the polymeric build material particles from coalescing during electromagnetic radiation exposure of the 3D printing process.
