Abstract

The invention discloses a rapid cooling and curing 3D printing material and a preparation method thereof, and belongs to the technical field of 3D printing. The 3D printing material is prepared from the following raw material components in parts by mass: 70 to 95 parts of polycaprolactone, 2 to 20 parts of elastomer, 1 to 6 parts of ionization reagent, 1 to 2 parts of nucleating agent and 1 to 2 parts of antioxidant, and the ionization reagent is at least one of sodium acrylate, calcium benzenesulfonate, calcium hydroxide, sodium toluenesulfonate or ethylene-sodium methacrylate. According to the invention, polycaprolactone is subjected to modification treatment by adopting an ionization reagent, so that the melt index of the prepared printing material is reduced, and the problem of hand sticking is avoided under the condition of meeting proper flowability. The 3D printing material can be well applied to the fields of 3D printing and medical treatment and public health.

Description

technical field

[0001] The invention relates to a 3D printing material, which belongs to the technical field of 3D printing, in particular to a rapidly cooling and solidifying 3D printing material and a preparation method thereof. Background technique

[0002] Polycaprolactone (PCL) is a consumable mainly used for supporting 3D printing, with a low melting point of only about 60°C; like most biological materials, it is often used for special purposes such as drug delivery devices, sutures etc. At the same time, PCL also has shape memory. In 3D printing, because of its low melting point, it does not require a high printing temperature, so as to achieve the purpose of energy saving. At the same time, due to its low melting point, it can effectively avoid burns when operating personnel. In addition, because it has the characteristic of shape memory, it makes the printed things have "memory", and under certain conditions, it can return to the original set shape. In the medica...
