Embodiment 1

[0029] A method for preparing a luminous PLA wire for 3D printing, comprising the following steps:

[0030] (1) Weigh 99% PLA plastic and 1% phosphorescent plastic masterbatch to prepare;

[0031] (2) After drying the above raw materials in an oven at 80°C for 4 to 6 hours, place them in a high-speed mixer and fully stir and mix them for 20 minutes;

[0032] (3) Put the mixed raw materials in a twin-screw granulator, heat them at a high temperature of 170-200°C, pass through the screw basic raw materials with a rotation speed of 15-50rpm, and cut the extruded wire raw materials through the granulator into 5 ~ 10mm composite particles;

[0033] (4) Place the prepared composite particles in an oven at 80° C. for 4 to 6 hours to dry;

[0034] (5) Finally, the dried composite particles were processed into a 3D printing PLA filament with a diameter of 2.85mm and a luminescent effect by a twin-screw extruder at a temperature of 175-190° C. and a speed of 40-50 rpm.

Embodiment 2

[0036] A method for preparing a luminous PLA wire for 3D printing, comprising the following steps:

[0037] (1) Weigh 90% PLA plastic and 10% phosphorescent plastic masterbatch to prepare;

[0038] (2) After drying the above raw materials in an oven at 80°C for 4 to 6 hours, place them in a high-speed mixer and fully stir and mix them for 20 minutes;

[0039] (3) Put the mixed raw materials in a twin-screw granulator, heat them at a high temperature of 170-180°C, pass through the screw basic raw materials with a rotation speed of 15-50rpm, and cut the extruded wire raw materials through the granulator into 5 ~ 10mm composite particles;

[0040] (4) Place the prepared composite particles in an oven at 80° C. for 4 to 6 hours to dry;

[0041] (5) Finally, the dried composite particles were processed into a 3D printing PLA filament with a diameter of 2.85mm and a luminescent effect by a twin-screw extruder at a temperature of 175-190° C. and a speed of 30-40 rpm.

Embodiment 3

[0043] A method for preparing a luminous PLA wire for 3D printing, comprising the following steps:

[0044] (1) Weigh 70% PLA plastic and 30% phosphorescent plastic masterbatch to prepare;

[0045] (2) After drying the above raw materials in an oven at 80°C for 4 to 6 hours, place them in a high-speed mixer and fully stir and mix them for 20 minutes;

[0046] (3) Put the mixed raw materials in a twin-screw granulator, heat them at a high temperature of 175-185°C, pass through the screw basic raw materials with a rotation speed of 15-50rpm, and cut the extruded wire raw materials through the granulator into 5 ~ 10mm composite particles;

[0047] (4) Place the prepared composite particles in an oven at 80° C. for 4 to 6 hours to dry;

[0048] (5) Finally, the dried composite particles were processed into a 3D printing PLA filament with a diameter of 1.75mm and a luminescent effect by a twin-screw extruder at a temperature of 175-190° C. and a speed of 20-30 rpm.

Abstract

The invention belongs to the field of 3D printing, and particularly relates to a light-emitting PLA wire for 3D printing and a preparation method and application thereof. The preparation method comprises the steps that 60%-99% of PLA plastic and 1%-50% of phosphorescence plastic master batches by weight are blended in proportion; the blended raw materials are dried, stirred and mixed; the mixed raw materials are subjected to extrusion pelletization and extruded after being cut, or the mixed raw materials are directly extruded, and the light-emitting PLA wire for 3D printing is prepared. By means of the prepared light-emitting PLA wire for 3D printing, the toy market can be widened, a new 3D printing product market such as safety marks, traffic boards and switches can be opened, and meanwhile the light-emitting PLA wire can also be used for the field of artworks and decorations. The light-emitting PLA wire is beneficial to diversification and functionalization of 3D printing materials, and the application range of 3D printing in the fields of life and industry is widened.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a luminescent PLA wire for 3D printing, a preparation method and application thereof. Background technique [0002] After nearly 30 years of development, 3D printing technology is rapidly entering our production and life in recent years, from popular science products such as portrait printing and toy manufacturing in the past few years to direct printing of functional products. PLA wire is the main consumable for fused deposition (FDM) 3D printing. As the society becomes more and more functional for 3D printing products, PLA, the main material for 3D printing, also wants to diversify and develop functionally. For example, the biological Degradability, medical properties, etc. But so far there is no composite consumable with luminous effect for 3D printing. Contents of the invention [0003] In order to solve the shortcomings and deficiencies of the prior art, the primar...
