Abstract

The invention discloses a head device for a 3D printer. The printer comprises a linear bearing which sleeves a cross optical shaft of the 3D printer and a head carrier which sleeves the linear bearing, the bottom of the head carrier is connected with a motor fixing frame through a connecting column, the motor fixing frame comprises a motor upper bracket and a motor lower bracket on an outer wall of one side of the motor upper bracket, the same motor is fixed on the motor upper bracket and the motor lower bracket, the output shaft of the motor is sleeved with a feeding wheel, the outer wall ofthe motor lower bracket is connected with a driven wheel which meshes with the feeding wheel, the bottom of the motor lower bracket is connected with a hollow throat, the upper outer wall of the hollow throat is provided with heat dissipating blocks which are equidistantly distributed, and the lower portion of the hollow throat is sleeved with a heating block. The device runs more smoothly, can quickly load and unload materials, has smooth silk output, feeds a silk at the proximal end, is beneficial to the withdrawal of the consumables, can reduce the drawing phenomenon, and has better printing effect, the hollow throat is durable, and the heat dissipation performance is good.

Description

technical field

[0001] The invention relates to the technical field of 3D printing, in particular to a head device for a 3D printer. Background technique

[0002] Rapid Prototyping Manufacturing (RPM for short) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. RPM printing is usually achieved with digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others.
