Consumable material with uniform color distribution for 3D printing pen

Abstract

The invention discloses a consumable material with uniform color distribution for a 3D printing pen. The consumable material is composed of oligomers, a photoinitiator, an assistant initiating agent,a surface active agent, a suspending agent, photodiffusion power and color paste or toner. The raw materials comprise, by weight, 60%-88% of oligomers, 1%-12% of photoinitiator, 1%-6% of assistant initiating agent, 1%-6% of surface active agent, 1%-3% of antisticking agent, 0.1%-3% of suspending agent, 0.5%-2% of photodiffusion power and the balance color paste or toner. The cost of the nonsticking consumable material for the printing pen is 10% of the cost of the traditional consumable material, the solidifying temperature rise is required to be within 45 DEG C, the solidifying time is within8 s, overquick solidifying speed can easily cause uneven color distribution, and the suspending agent is added to avoid uneven color distribution in the material preparation and solidifying processesof the color paste or toner, so that color and the whole system are uniform, the suspending performance is added, the color paste or toner does not precipitate, the physico-chemical property of the whole system is same, and color distribution is uniform.

Description

technical field [0001] The invention belongs to the field of 3D printers, and in particular relates to a consumable with uniform color distribution for a 3D printing pen. Background technique [0002] 3D printing pen technology is a revolutionary industrial molding technology. Compared with traditional painting, it is more vivid and increases children's hands-on ability. Raw materials can be directly shaped by a 3D printer. It is a digital model file-based technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing without the need for mold manufacturing. It saves the time and cost of mold manufacturing. With the rapid development of 3D printing technology, its requirements for materials are also rapidly increasing. At present, our company has developed a 3D printing pen consumable that has a low curing temperature (within 45°C), does not require electrified operation, and has a fast curing speed, which can be cu...

AI Technical Summary

Problems solved by technology

At present, our company has developed a 3D printing pen consumable that has a low curing temperature (within 45°C), does not require electrified operation, and has a fast curing speed, which can be cured within 8s. The sedimentation of the powder will also cause differences in the physical and chemical properties of the overall system after the product is cured, and the color distribution will be uneven
