The present disclosure provides a photo-curable elastic ink composition for three-dimensional printing and the preparation method. The ink composition includes approximately 10%-75% of a soft monomer, approximately 10%-75% of a hard monomer, approximately 5%-20% of a cross-linking agent, approximately 5%-20% of a non-reactive soft resin, approximately 0.5%-10% of a photo-initiator, approximately 0%-0.5% of a colorant, and approximately 0.05%-8% of an auxiliary agent. The soft monomer is capable of generating a homopolymer with a glass transition temperature lower than about 25&#xb0; C. The hard monomer is capable of generating a homopolymer with a glass transition temperature of about 25&#xb0; C. or higher. The non-reactive soft resin is a resin without containing any radiation curable group in the molecular structure and having a glass transition temperature less than 0&#xb0; C.

Photo-curable elastic ink composition for three-dimensional printing

A photocurable transparent ink composition for three-dimensional molding includes the following components in parts by weight: 60-125 parts of a photocuring agent, 0.01-5 parts of a yellowing adjusting agent, 0.5-5 parts of a photoinitiator, and 0.5-5 parts of an auxiliary agent, where the yellowing adjusting agent can absorb light in a wavelength range of 560 nm to 650 nm, so that the ink composition appears transparent. The photocurable transparent ink composition for three-dimensional molding can prevent yellowing of a printed article and make the printed article show a whiter, more transparent, and brighter appearance.

Photocurable transparent ink composition for three-dimensional molding and preparation method and application thereof

The present disclosure provides a light curing non-transparent material for 3D printing and a preparation method thereof, a 3D printed product and a 3D printer. The light curing non-transparent material for 3D printing provided by the present disclosure can be used to print non-transparent 3D printed products without adding white pigments such as white pigments powder, and therefore has the characteristic of high stability, and also ensures fluency of the 3D printing process, good quality of the 3D printed products, as well as good performances of the 3D printer that containing light curing non-transparent material for 3D printing.
