Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of 3D printers, and particularly relates to a heating mechanism for a 3D printer. BACKGROUND

[0002] 3D printing (3DP) is a rapid prototyping technique, also known as additive manufacturing, which is a technique for constructing objects through layer-by-layer printing based on a digital model file, using materials such as powdered metal or plastic that can be bonded. 3D printing is usually realized by using a digital technology material printer. It is often used in mold manufacturing, industrial design and other fields to manufacture models, and is gradually used for direct manufacturing of some products. There are parts printed by using this technology. The technology is applied in the fields of jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobiles, aerospace, dental and medical industry, education, geographic information system, civil engineering and other fields.

[0003] Since the consumables for 3D printing have the characteristics of heating expansion and cooling shrinkage. When the extrusion device of the printer heats the consumables to melt, the consumables will be separated from the workbench due to shape change, resulting in printing failure when the workbench is cooled and shrunk sharply. Therefore, the function of the heating mechanism is to heat the workbench, improve the temperature, and reduce the temperature difference of the consumables as much as possible to avoid the influence of consumable loss on printing efficiency.
