Boron-methylated dipyrromethene technology for rapid radical polymerizations using low-intensity green light
Background Visible light has emerged as a promising stimulus to drive polymerizations for a variety of applications, particularly in the biomedical and advanced manufacturing arenas such as 3D printing. This is due to its inherent spatio­temporal control, high penetration depth, low energy, and discrete absorption, which enable benign and wavelength-selective...

A device for deagglomerating fine powders in aerosol-based processes
Background The field of powder technology is crucial in various industries, including pharmaceuticals, ceramics, and metallurgy, where the manipulation and processing of fine powders are essential. A significant challenge in this field is the tendency of fine powders to agglomerate, forming larger clusters that can impede the efficiency and quality...

Nozzle design for high-velocity deposition of ceramic nanoparticles
Background The micro-cold spray (MCS) method offers a promising technique for produc­ing dense metal and ceramic films with thicknesses ranging from 1 to 100 μm. Unlike conventional methods, MCS operates by aerosolizing particles (with diameters ranging from 200 nm to 5 μm) in a carrier gas, which are then accelerated through a nozzle into...

Oxygen-tolerant photopolymer resins
BackgroundLight-driven polymerization methods for 3D printing are particularly attractive due to unparalleled speed and resolution, yet the reliance on high energy UV/​violet light in contemporary processes limits the number of compatible materials due to pervasive absorption, scattering, and degradation at these short wavelengths. Such issues can be...

Visible to near-infrared light activated photopolymer resins
BackgroundResin 3D printing has many advantages, such as high precision, smooth surface finish, and rapid printing speed. Conventional LCD or DLP devices use ultraviolet (UV) light to activate photo-initiators in the resin. A cheaper, less power hungry, and more biocompatible alternative would be to use visible light to activate photo-sensitizers in...

Flash-sintered additive manufacturing
Background Ceramics have been found useful in increasingly diverse applications in modern industry because of their high mechanical strength, low thermal conductivity, and high wear and corrosion resistance. In addition, the bio-compatibility of some ceramics allows them to be used for body prostheses, dental, and tissue engineering scaffolds. These...
