Additive manufacturing, commonly known as 3D printing, has revolutionized product design and prototyping, enabling the creation of complex geometries with high precision. A significant driver of this advancement is photopolymerization, a process where liquid resins are selectively cured by light. Within this context, photoinitiators play a pivotal role. Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, or TPO (CAS 75980-60-8), has gained prominence for its suitability in various 3D printing technologies, particularly those employing UV or visible light sources.

TPO is an efficient free-radical photoinitiator that is compatible with many common monomers and oligomers used in 3D printing resins. Its ability to absorb light at wavelengths commonly used by 3D printers, such as 405 nm, makes it an ideal candidate for stereolithography (SLA) and Digital Light Processing (DLP) technologies. Upon exposure to light, TPO generates reactive free radicals that initiate the rapid polymerization of the resin, layer by layer, to build the desired three-dimensional object. The performance of TPO in these applications translates to faster print speeds and improved resolution.

Beyond standard 3D printing, TPO's unique properties are also being explored in the development of advanced materials. For instance, its use in photo-crosslinking of PMMA composites for organic thin-film transistors (OTFTs) highlights its potential in the electronics sector. Researchers are also investigating its role in creating photocurable urethane-acrylate coatings and in photoinduced reactions for organophosphine compounds, which can serve as ligands for metal catalysts. The high purity and consistent quality of TPO from reliable manufacturers are essential for these cutting-edge applications.
