3D printing conveying device for pasty materials

Abstract

The invention discloses a 3D printing conveying device for pasty materials. The 3D printing device for the pasty materials comprises a material bed, a forming mechanism, a supply mechanism and a bottom plate which is installed at the bottom of the material bed, the forming mechanism and the supply mechanism are adjacently arranged on the material bed, and the forming mechanism comprises a replaceable forming cylinder, a base plate and a first piston plate; the base plate and the first piston plate are slidingly arranged on the inner wall of the forming cylinder from top to bottom in sequence,the supply mechanism comprises a supply cylinder which is adjacent to the forming cylinder, a second piston plate slidingly arranged on the inner wall of the supply cylinder and a supply plate installed at the top of the supply cylinder through screws, and the first piston plate and the second piston plate are vertically connected with one or more thrust cylinders respectively. The 3D printing conveying device for the pasty materials helps the supply amount in the supply cylinder to meet the printing requirement, the printing precision is improved, the structural design is reasonable, and theapplicability is high.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a 3D printing feeding device for paste materials, which is suitable for ceramic 3D printing technology and also for 3D printing technology for printing paste objects. Background technique [0002] 3D printing equipment, also known as a three-dimensional printer, is a kind of additive manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic, ceramics, etc. Composite materials, which create three-dimensional objects by printing multiple layers of adhesive materials. A wide variety of media can be used for printing, from a wide range of plastics to metals, ceramic-like pastes, and rubber-like materials. [0003] Paste materials such as ceramics have excellent mechanical properties (high strength, high hardness, high wear resistance), thermal properties (high tempera...

AI Technical Summary

Problems solved by technology

This kind of ceramic material has high viscosity and no fluidity, and it is easy to generate air bubbles during production, which makes it difficult to realize feeding of ceramic materials, so it becomes a key point of 3D printing ceramic materials, so a design suitable for paste materials 3D printing feeding device is very necessary
