Composition for 3D printing |
摘要 |
The present invention relates to polymer compositions suitable for 3D printing. The composition comprises 60 to 80 mass % of oligoester acrylate; 10 to 30 mass % of a liquid polyethylene glycol; 7 to 9 mass % of a non-liquid polyethylene glycol; and 0.1 to 1 mass % of a system of photopolymerization initiators. A distinguishing feature of the composition is that after being extruded at an environment temperature of 22° C. with the extrusion rate of 2.5 to 3.5 cm/sec through a nozzle of a hand-held 3D printing device having an output orifice with a diameter in the range of 0.6 to 1.5 mm and after being irradiated after extrusion with a light having a wavelength in the range of 390 to 410 nm by LEDs having a total power of 2 Wt, the composition maintained its shape without a support. |

1. A composition for 3D printing comprising: 60 to 80 mass % of oligoester acrylate; 10 to 30 mass % of a liquid polyethylene glycol; 7 to 9 mass % of a non-liquid polyethylene glycol; and 0.1 to 1 mass % of a system of photopolymerization initiators, wherein the oligoester acrylate comprises a dimethacrylic ester of triethylelene glycol which is a non-toxic homogenous transparent liquid soluble in organic solvents and insoluble in water and wherein the oligoester acrylate is produced by condensation-type telomerization from methacrylic acid, triethylene glycol, and fluoroanhydride. |
