Abstract

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a component present therein. Composite filaments suitable for additive manufacturing may comprise a continuous polymer phase of a first thermoplastic polymer and a second thermoplastic polymer that are immiscible with one another, and electrically conductive particles distributed in the continuous polymer phase, such as microparticles, nanoparticles, or any combination thereof. The first thermoplastic polymer is dissolvable or degradable and the second thermoplastic polymer is insoluble or non-degradable under specified conditions. Removal of the first thermoplastic polymer from a printed part may introduce porosity thereto, thereby inducing or enhancing piezoresistivity within the printed part. An aqueous mixture comprising the electrically conductive particles and the first and second thermoplastic polymers may have water removed therefrom, and the resulting composite residue may be extruded to form the composite filaments.

The composite filament is compatible with fused filament fabrication and has a length and diameter compatible with fused filament fabrication, and the piezoelectric particles are substantially non-agglomerated and dispersed along the length of the composite filament. The piezoelectric particles may remain substantially non-agglomerated when dispersed in the thermoplastic polymer through melt blending. Additive manufacturing processes may comprise heating such a composite filament at or above a melting point or softening temperature thereof to form a softened composite material, and depositing the softened composite material layer by layer to form a printed part.

Abstract

Additive manufacturing processes, such as fused filament fabrication, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of a printed object. Conductive traces and similar features may be introduced in conjunction with fused filament fabrication processes by incorporating a metal precursor in a polymer filament having a filament body comprising a thermoplastic polymer, and forming a printed object from the polymer filament through layer-by-layer deposition, in which the metal precursor remains substantially unconverted to metal while forming the printed object. Suitable polymer filaments compatible with fused filament fabrication may comprise a thermoplastic polymer defining a filament body, and a metal precursor contacting the filament body, in which the metal precursor is activatable to form metal islands upon laser irradiation.

Abstract

Melt emulsification may be employed to form elastomeric particulates in a narrow size range when nanoparticles are included as an emulsion stabilizer. Such processes may comprise combining a polyurethane polymer and nanoparticles with a carrier fluid at a heating temperature at or above a melting point or a softening temperature of the polyurethane polymer, applying sufficient shear to disperse the polyurethane polymer as liquefied droplets in the presence of the nanoparticles in the carrier fluid at the heating temperature, cooling the carrier fluid at least until elastomeric particulates in a solidified state foini, and separating the elastomeric particulates from the carrier fluid. In the elastomeric particulates, the polyurethane polymer defines a core and an outer surface of the elastomeric particulates and the nanoparticles are associated with the outer surface. The elastomeric particulates may have a D50 of about 1 [im to about 1,000 m.

Abstract

-1- METHOD FOR PRODUCING SULFONE POLYMER MICRO-PARTICLES FOR SLS 3D PRINTING [0001] The present disclosure relates generally to materials for three- dimensional printing and, more particularly, to a method for producing sulfone polymer micro-particles for selective laser sintering (SLS) three-dimensional (3D) printing. BACKGROUND [0002] Selective laser sintering (SLS) is a powder bed-based additive manufacturing (AM) technique to produce complex three-dimensional parts. When a laser beam scans the powder, the powder melts due to the rising temperature and layer-by-layer the final part approaches full density and should result in properties of the bulk material (i.e., polymer). In theory, every thermoplastic polymer that can be transformed into a powder form can be processed via this technique. However, the reality is every new material behaves differently during melting, coalescence, and consolidation, and requires optimization of the SLS processing parameters. The bed temperature and laser energy input are chosen based on the "processing" window of the polymer's thermal profile as well as its energy absorption. Laser parameters also need to be optimized based on the powder's particle size and shape. [0003] The availability of powder materials for SLS is limited, where about 95% of the materials market consists of polyamide-12 which is a crystalline nylon grade polymer. High glass transition flexible amorphous materials such polysulfone (PSU) are not available as printable powders. Unlike semi- crystalline polymer powders, amorphous polymer powder must be heated above the glass transition temperature, at which the polymer is in a much more viscous state than semi-crystalline polymers at similar temperatures. Semi- crystalline polymers are highly ordered molecules with sharp melting points (Tm). Unlike amorphous polymers, they do not gradually soften as the temperature increases, but instead remain hard until a given amount of heat is absorbed and then rapidly transform into a viscous liquid. When a semi- crystalline material is above the Tm, it has very low viscosity and will flow and

Abstract

Methods of using a toner as a printable adhesive are provided. In embodiments, a method of adhering substrates is provided which comprises disposing a cold pressure fix toner comprising a phase change material on a first substrate via xerography to form an unfused layer of the cold pressure fix toner on the first substrate; placing a second substrate on the unfused layer of the cold pressure fix toner; and subjecting the cold pressure fix toner to a pressure to form a bonded article comprising the first substrate, an adhesive layer formed from the cold pressure fix toner, and the second substrate. Methods of applying an adhesive to a substrate and bonded articles are also provided.
