Three-dimension printer

Abstract

The invention relates to a three-dimension printer. The three-dimension printer comprises a host body, wherein a construct platform is arranged on the host body, exhausting equipment and a filter are arranged in the host body, and an ink feeding unit frame is erected outside the host body; a feeding chamber erected on the construct platform for temporary storage of a powder construct material; a construct chamber erected on the construct platform for stacking the powder construct material for moulding; a construct displacement mechanism erected on the construct platform for performing relative displacement; and a jet printing module arranged on the construct displacement mechanism for performing link displacement, wherein a jet printing displacement mechanism drives a supporting seat used for bearing a built-in cartridge to perform reciprocating displacement, a waste print cartridge is fixed by one end of the jet printing displacement mechanism, a pushing stopping roller is arranged at the bottom of the jet printing module, so that the powder construct material is pushed into the construct chamber. Thereby, three dimensional object moulding work through laminated jet printing is completed.

Description

【Technical field】 [0001] The invention relates to a rapid prototyping device, in particular to a three-dimensional printer which can be placed on a table and operated with a greatly reduced volume. 【Background technique】 [0002] With the advancement of science and technology, 3D printing technology is quietly emerging recently, which is a potential technology capable of changing the production method of products. Even if only one item is processed, the input cost is low, and any shape item can be processed freely. It is expected that 3D printing technology will change the technical thinking in many aspects such as manufacturing, medical treatment and IT, and lead the innovation of the industry. 3D printing technology has been applied in part of the production process in the industry. For example, in the field of biomedicine, 3D printers can be used as the main structure to manufacture the required 3D medical finished products, and even various unique finished products such ...

Problems solved by technology

However, regardless of the 3D printing of any material, there is a certain degree of pollution. For example, a 3D printer made of resin, because it is formed by hot-melt plastic, will emit a toxic smell of burning plastic, while a powder-based 3D printer will cause pollution. The environment has a thin layer of powder

Such 3D printers are too numerous to enumerate. These are only environmental pollution, and the most serious ones are inhaled into the digestive system of the human body. Over time, they will cause the poisonous chemical substances in the body organs.

[0004] As far as the price of 3D printers on the market is concerned, although 3D printers using resin materials are relatively cheap, their processing and forming precision is low, and support materials are needed to assist in forming complex structures, but the support materials are not recyclable, which will also cause environmental problems. , so it has problems such as highly toxic molten materials and environmental pollution of support materials. Therefore, in terms of price promotion in the market, although it has the advantages of miniaturization, low cost and popularization, it still causes some environmental protection and health hazards. , there are still many scruples in implementation, and it is still unable to be widely used in industries that require applications in daily life
