Abstract
Official abstract text for this publication.
The present disclosure is drawn to 3-dimensional printed parts that can include a conductive composite portion and an insulating portion. The conductive composite portion can include a matrix of fused thermoplastic polymer particles interlocked with a matrix of sintered elemental transition metal particles. The insulating portion can include a matrix of fused thermoplastic polymer particles that are continuous with the matrix of fused thermoplastic polymer particles in the conductive composite portion. The insulating portion can be substantially free of sintered elemental transition metal particles and can include transition metal oxide bronze particles.
First claim
Opening claim text (preview).
What is claimed is: 1. A 3-dimensional printed part, comprising: two conductive composite portions, each of which comprises a matrix of fused thermoplastic polymer particles interlocked with a matrix of sintered elemental transition metal particles; and an insulating portion positioned between the two conductive composite portions, the insulating portion comprising a matrix of fused thermoplastic polymer particles that is continuous with the matrix of fused thermoplastic polymer particles in the conductive composite portions, wherein the insulating portion is substantially free of the sintered elemental transition metal particles, and wherein the insulating portion comprises transition metal oxide bronze particles. 2. The 3-dimensional printed part of claim 1 , wherein the sintered elemental transition metal particles comprise silver particles, copper particles, gold particles, or combinations thereof. 3. The 3-dimensional printed part of claim 1 , wherein the sintered elemental transition metal particles are generated from elemental transition metal particles having an average particle size from 10 nm-200 nm. 4. The 3-dimensional printed part of claim 1 , wherein the transition metal oxide bronze particles comprise a tungsten bronze, a molybdenum bronze, or combinations thereof. 5. The 3-dimensional printed part of claim 1 , wherein the transition metal oxide bronze particles comprise a cesium tungsten bronze with a composition Cs x WO 3 (0<x<1) having an average particle size of 2 nm-200 nm. 6. The 3-dimensional printed part of claim 1 , wherein the two conductive composite portions further include conductive fusing agent composition components introduced to the thermoplastic polymer particles with elemental transition metal particles to form the sintered elemental transition metal particles. 7. The 3-dimensional printed part of claim 1 , wherein the insulating portion further includes nonconductive fusing agent composition components introduced to the thermoplastic polymer particles with the transition metal oxide bronze particles. 8. A 3-dimensional printed part, comprising: a conductive composite portion comprising a matrix of fused thermoplastic polymer particles interlocked with a matrix of sintered elemental transition metal particles; and an insulating portion comprising a matrix of fused thermoplastic polymer particles that is continuous with the matrix of fused thermoplastic polymer particles in the conductive composite portion, wherein the insulating portion is substantially free of sintered elemental transition metal particles, wherein the insulating portion comprises transition metal oxide bronze particles, and wherein the insulating portion substantially prevents crosstalk between two of the conductive composite portions. 9. The 3-dimensional printed part of claim 1 , wherein the two conductive composite portions and the insulating portion are thermally fused.
